With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data. Other speakers on dayside reconnection are (in no particular order) Joo Hwang, Sun Hee Lee, Richard Denton, Jan Egedal, Rishi Mistry, Kris Maynard, and Cong Zhao. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). Other speakers on magnetotail reconnection are (in no particular order) Yongliang Zhang, Stefan Kiehas, Haoming Liang, Misha Sitnov, Andrei Runov, Joachim Birn, Phil Pritchett, and Tony Lui.<br /> <br /> ==== [FG] (Joint) Storm-time Inner Magnetosphere-Ionosphere Convection + Inner Magnetosphere Cross-Energy/Population Interactions ====<br /> <br /> Location: SFCC O'Keefe/Milagro/Kearny<br /> <br /> *Topic: Impact of large-scale or transient electric fields on inner magnetosphere populations, and the role of particle precipitation of magnetospheric origin on the ionospheric electrodynamics<br /> * Chairs: Stanislav Sazykin, Yiqun Yu<br /> #Richard Selesnick: Control of the inner electron radiation belt by large-scale electric fields<br /> #Sam Califf: Van Allen Probes observations of subauroral polarization streams (SAPS) electric fields<br /> #Scott Thaller: Van Allen Probes investing of the night/dusk asymmetries of the plasmapause and dawn-dusk electric field, a synoptic study<br /> #Joe Huba : Storm-time electrodynamics of the ionosphere/plasmasphere system using SAMI3/RCM<br /> #Carlos Martinis: Coincident observations of all-sky images and Van Allen Probes<br /> #Raluca Ilie: TBD<br /> #Yiqun Yu: A new ionospheric precipitation module coupled with RAM-SCB in geospace general circulation model<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:GEM_CEDAR_Modeling_Challenge GEM-CEDAR Modeling Challenge] ====<br /> <br /> Location: SFCC Sweeney B<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:Particle_Precipitation Particle Precipitation and the Effects on Earth's Atmosphere] ====<br /> <br /> Location: SFCC Coronado/DeVargas<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:Data_Integration_in_Geospace Data Integration in Geospace] ====<br /> <br /> Location: Eldorado, Zia<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:High_Latitude_Geospace_System Grand Challenge: The High-Latitude Geospace System] ====<br /> <br /> <br /> Location: SFCC Sweeney E/F<br /> <br /> === 1600-1800: Splinter Sessions ===<br /> <br /> ==== [FG] M3-I2: Merged Modeling &amp; Measurement of Injection Ionospheric Plasma into the Magnetosphere and Its Effects ====<br /> <br /> Location: SFCC Sweeney A<br /> <br /> *MONDAY PM2 16:00-18:00 SFCC SWEENEY A (GEM-CEDAR JOINT SESSION)<br /> *Topic: Polar Wind Models and the Ionospheric Boundary Definition<br /> *Chair: Shasha Zou Scribe: Barbara Giles<br /> #Roger Varney (Invited) - Ion Energization in Polar Wind Models<br /> #George Khazanov (Invited) - Polar Wind M-I-T Coupling: Kinetic Versus Hydrodynamic<br /> *Short contributed presentations with discussion <br /> #Shunrong Zhang - ISR Campaigns<br /> #Doug Roland - Vision Sounding Rocket<br /> #Bruce Fritz - Renu Sounding Rocket<br /> #Bill Peterson - ePoP<br /> *Open Floor Discussion (bring a slide)<br /> #Questions &amp; methodology on ionospheric boundary layer and ion energization.<br /> #F-region/topside ionosphere processes as lower boundary<br /> #Polar wind<br /> #Model-measurement comparisons<br /> <br /> ==== [FG] (Joint) Magnetic Reconnection in the Magnetosphere + Testing Proposed Links between Mesoscale Auroral and Polar Cap Dynamics and Substorms ====<br /> <br /> Location: SFCC Sweeney C<br /> <br /> The joint session will focus on the signatures and consequences of magnetic reconnection within the magnetosphere and ionosphere.

With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data. Other speakers on dayside reconnection are (in no particular order) Joo Hwang, Sun Hee Lee, Richard Denton, Jan Egedal, Rishi Mistry, Kris Maynard, and Cong Zhao. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). Other speakers on magnetotail reconnection are (in no particular order) Yongliang Zhang, Stefan Kiehas, Haoming Liang, Misha Sitnov, Andrei Runov, Joachim Birn, Phil Pritchett, and Tony Lui.<br /> <br /> ==== [FG] (Joint) Storm-time Inner Magnetosphere-Ionosphere Convection + Inner Magnetosphere Cross-Energy/Population Interactions ====<br /> <br /> Location: SFCC O'Keefe/Milagro/Kearny<br /> <br /> *Topic: Impact of large-scale or transient electric fields on inner magnetosphere populations, and the role of particle precipitation of magnetospheric origin on the ionospheric electrodynamics<br /> * Chairs: Stanislav Sazykin, Yiqun Yu<br /> #Richard Selesnick: Control of the inner electron radiation belt by large-scale electric fields<br /> #Sam Califf: Van Allen Probes observations of subauroral polarization streams (SAPS) electric fields<br /> #Scott Thaller: Van Allen Probes investing of the night/dusk asymmetries of the plasmapause and dawn-dusk electric field, a synoptic study<br /> #Joe Huba : Storm-time electrodynamics of the ionosphere/plasmasphere system using SAMI3/RCM<br /> #Carlos Martinis: Coincident observations of all-sky images and Van Allen Probes<br /> #Raluca Ilie: TBD<br /> #Yiqun Yu: A new ionospheric precipitation module coupled with RAM-SCB in geospace general circulation model<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:GEM_CEDAR_Modeling_Challenge GEM-CEDAR Modeling Challenge] ====<br /> <br /> Location: SFCC Sweeney B<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:Particle_Precipitation Particle Precipitation and the Effects on Earth's Atmosphere] ====<br /> <br /> Location: SFCC Coronado/DeVargas<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:Data_Integration_in_Geospace Data Integration in Geospace] ====<br /> <br /> Location: Eldorado, Zia<br /> <br /> ==== [GEM-CEDAR] [http://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:High_Latitude_Geospace_System Grand Challenge: The High-Latitude Geospace System] ====<br /> <br /> <br /> Location: SFCC Sweeney E/F<br /> <br /> === 1600-1800: Splinter Sessions ===<br /> <br /> ==== [FG] M3-I2: Merged Modeling &amp; Measurement of Injection Ionospheric Plasma into the Magnetosphere and Its Effects ====<br /> <br /> Location: SFCC Sweeney A<br /> <br /> *MONDAY PM2 16:00-18:00 SFCC SWEENEY A (GEM-CEDAR JOINT SESSION)<br /> *Topic: Polar Wind Models and the Ionospheric Boundary Definition<br /> *Chair: Shasha Zou Scribe: Barbara Giles<br /> #Roger Varney (Invited) - Ion Energization in Polar Wind Models<br /> #George Khazanov (Invited) - Polar Wind M-I-T Coupling: Kinetic Versus Hydrodynamic<br /> *Short contributed presentations with discussion <br /> #Shunrong Zhang - ISR Campaigns<br /> #Doug Roland - Vision Sounding Rocket<br /> #Bruce Fritz - Renu Sounding Rocket<br /> #Bill Peterson - ePoP<br /> *Open Floor Discussion (bring a slide)<br /> #Questions &amp; methodology on ionospheric boundary layer and ion energization.<br /> #F-region/topside ionosphere processes as lower boundary<br /> #Polar wind<br /> #Model-measurement comparisons<br /> <br /> ==== [FG] (Joint) Magnetic Reconnection in the Magnetosphere + Testing Proposed Links between Mesoscale Auroral and Polar Cap Dynamics and Substorms ====<br /> <br /> Location: SFCC Sweeney C<br /> <br /> The joint session will focus on the signatures and consequences of magnetic reconnection within the magnetosphere and ionosphere.

The information here serves as a rough guide for those who wish to know the most updated session plans. Due to the nature of the GEM Workshop, Focus Groups may continue to revise their agenda as needed.<br /> <br /> All other information about the 2016 Joint GEM-CEDAR Workshop can be found at [http://www.cpe.vt.edu/gem/index.html the GEM Meeting Coordinator Website] and [https://cedarweb.vsp.ucar.edu/wiki/index.php/2016_Workshop:Main the CEDARwiki 2016 Workshop Page]. <br /> <br /> == Monday, June 20 ==<br /> <br /> === 0815-1000: Plenary Session ===<br /> <br /> * '''Welcome''' by ''Josh Semeter, Mike Wiltberger, Students, and Therese Moretto Jorgensen'' <br /> <br /> * '''Tutorial GC#1''' by ''Roger Varney'' -- Geospace electrodynamics<br /> <br /> === 1025-1200: Plenary Session ===<br /> <br /> * '''Tutorial GC#2''' by ''Jesper Gjerloev'' -- Multiscale MI coupling<br /> <br /> === 1330-1530: Splinter Sessions ===<br /> <br /> ==== [FG] Merged Modeling &amp; Measurement of Injection Ionospheric Plasma into the Magnetosphere and Its Effects ====<br /> <br /> ==== [FG] Magnetic Reconnection in the Magnetosphere ====<br /> <br /> This session will focus on kinetic physics in day- and night-side reconnection. With the recent launch of the Magnetospheric Multiscale (MMS) satellites, there is already a wealth of new data on kinetic scale physics. Scene setting talks to frame relevant questions and generate discussion will include particle acceleration in dayside reconnection (Allison Jaynes, CU-Boulder) and how global/non-local physics impacts kinetic reconnection physics (John Dorelli, NASA-GSFC), both of which will include discussion of MMS data.

Antarctica is an important<br /> platform for some areas of Space Weather related research. Our purpose<br /> is to engage the Space Physics community to determine the most<br /> important research questions that are ripe for major advances in<br /> understanding that require or utilize Antarctic infrastructure that<br /> could feasibly be achieved in the coming decade. The reason for this<br /> is NSF Polar Programs has asked for guidance in setting priority for<br /> funding Antarctic Research due to constrained budgets. We are<br /> specifically also looking to determine technological, infrastructure<br /> or data sharing developments that can enable the proposed high<br /> priority research, opportunities in international cooperation that<br /> might help advance high priority research or other innovative<br /> arrangements.

Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers). <br /> <br /> We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are: <br /> <br /> * Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?<br /> * What model assumptions affect the model predictions significantly and lead to differences between models?<br /> * How does the magnetopause change during extreme events<br /> * How sensitive is model performance to changes of the boundary conditions?<br /> * Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?<br /> <br /> We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.<br /> <br /> '''Draft Agenda:'''<br /> (~12 min/ presentation, walk-ons welcome and we will adjust time appropriately)<br /> <br /> * Tim Guild: Introduction to Session<br /> * Bob Weigel: Validation of MHD Magnetosphere Models - Long-term, point, and single model analysis with measured solar wind inputs.<br /> * Bob Weigel: Validation of MHD Magnetosphere Models - Short-term, global, and intermodel comparisons with artificial solar wind inputs. <br /> * Lutz Rastaetter: Introduction to the Magnetopause Crossing Challenge. <br /> * Yari Collado-Vega: Events and observations for the magnetopause challenge. <br /> * Alex Glocer: The effects of the inner near Earth boundary conditions on MHD models. <br /> * Darren DeZeeuw: Virtual Model Repository tools to calculate metrics derived from CCMC runs. <br /> * All: Open Discussion<br /> <br /> ==== [IMS] Inner Magnetosphere Cross-Energy/Population Interactions (Amphitheater) ====<br /> Session 2: coupling of ring current plasma with fields (10min/talk)<br /> <br /> * Colby Lemon - Introduction of Session 2<br /> * Raluca Ilie - Self-consistent coupling of HEIDI and MHD fields<br /> * Cristian P.

The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated. These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events.

Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers). <br /> <br /> We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are: <br /> <br /> * Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?<br /> * What model assumptions affect the model predictions significantly and lead to differences between models?<br /> * How does the magnetopause change during extreme events<br /> * How sensitive is model performance to changes of the boundary conditions?<br /> * Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?<br /> <br /> We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.<br /> <br /> '''Draft Agenda:'''<br /> (~12 min/ presentation, walk-ons welcome and we will adjust time appropriately)<br /> <br /> * Tim Guild: Introduction to Session<br /> * Bob Weigel: Validation of MHD Magnetosphere Models - Long-term, point, and single model analysis with measured solar wind inputs.<br /> * Bob Weigel: Validation of MHD Magnetosphere Models - Short-term, global, and intermodel comparisons with artificial solar wind inputs. <br /> * Lutz Rastaetter: Introduction to the Magnetopause Crossing Challenge. <br /> * Yari Collado-Vega: Events and observations for the magnetopause challenge. <br /> * Alex Glocer: The effects of the inner near Earth boundary conditions on MHD models. <br /> * Darren DeZeeuw: Virtual Model Repository tools to calculate metrics derived from CCMC runs. <br /> * All: Open Discussion<br /> <br /> ==== [IMS] Inner Magnetosphere Cross-Energy/Population Interactions (Amphitheater) ====<br /> Session 2: coupling of ring current plasma with fields (10min/talk)<br /> <br /> * Colby Lemon - Introduction of Session 2<br /> * Raluca Ilie - Self-consistent coupling of HEIDI and MHD fields<br /> * Cristian P.

The goals for this session are: to show model results for extreme events in the magnetosphere, to share information about the range of conditions where models have been validated, to assess methods for validating model performance with limited observations (such as for early historical events), and to assess the reliability of a model outside the range in which it has been validated.

Specifically solicited are strategies to accommodate uncertainty in modeled physical processes (e.g. uncertain radiation belt diffusion coefficients), uncertainty in boundary conditions (e.g. upstream solar wind), or the validation of models at their boundaries (such as ground-based magnetometers). <br /> <br /> We will introduce a challenge based on previously run magnetopause standoff simulations that compared model results to magnetopause crossings of geo-synchronous satellites. The few crossings observed during strong events revealed significant discrepancies between the major magnetospheric MHD models. We plan to revisit the challenge on the basis of selected events with steady and changing solar wind conditions and observations near the nose of the magnetosphere. The role of boundary conditions applied at the inner boundary (e.g., ionospheric conductance and convection, plasma density and temperature, magnetic field) can be tested. Some of the questions that can be addressed are: <br /> <br /> * Which model is better suited to predict magnetopause position near the nose of the magnetosphere under typical conditions/storm time conditions?<br /> * What model assumptions affect the model predictions significantly and lead to differences between models?<br /> * How does the magnetopause change during extreme events<br /> * How sensitive is model performance to changes of the boundary conditions?<br /> * Can we define common settings for the inner boundary location, and the plasma density or temperature applied at this boundary?<br /> <br /> We also anticipate presentations on topics such as the influence of the plasma sheet boundary conditions on ring current development and also welcome specifications of uncertainties derived from observations and lessons from data assimilation and ensemble modeling methods.<br /> <br /> '''Draft Agenda:'''<br /> (~12 min/ presentation, walk-ons welcome and we will adjust time appropriately)<br /> <br /> * Tim Guild: Introduction to Session<br /> * Bob Weigel: Validation of MHD Magnetosphere Models - Long-term, point, and single model analysis with measured solar wind inputs.<br /> * Bob Weigel: Validation of MHD Magnetosphere Models - Short-term, global, and intermodel comparisons with artificial solar wind inputs. <br /> * Lutz Rastaetter: Introduction to the Magnetopause Crossing Challenge. <br /> * Yari Collado-Vega: Events and observations for the magnetopause challenge. <br /> * Alex Glocer: The effects of the inner near Earth boundary conditions on MHD models. <br /> * Darren DeZeeuw: Virtual Model Repository tools to calculate metrics derived from CCMC runs. <br /> * All: Open Discussion<br /> <br /> ==== [IMS] Inner Magnetosphere Cross-Energy/Population Interactions (Amphitheater) ====<br /> Session 2: coupling of ring current plasma with fields (10min/talk)<br /> <br /> * Colby Lemon - Introduction of Session 2<br /> * Raluca Ilie - Self-consistent coupling of HEIDI and MHD fields<br /> * Cristian P.

These results will guide our understanding of the magnetosphere under extreme conditions, and provide insight into what physics needs to be incorporated into models so that they perform better during extreme events.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner''' - Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu''' - Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi''' - Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu''' - Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto''' - Bow Shock interaction with Transient Solar Wind Structures<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner''' - Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu''' - Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi''' - Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu''' - Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto''' - Bow Shock interaction with Transient Solar Wind Structures<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

Zong, University of Massachusetts Lowell (qgzong@gmail.com)<br /> <br /> Michael Ruohoniemi, Virginia Polytechnic and State University (mikeruo@vt.edu)<br /> <br /> David Murr, Augsburg College (murrdl@augsburg.edu)<br /> <br /> ===Description===<br /> The &quot;Transient Phenomena at the Magnetopause and Bow Shock and Their Ground Signatures&quot; focus group will employ both observations and simulations to investigate the transient phenomena at the magnetopause and bow shock and their ground signatures. The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner''' - Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu''' - Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi''' - Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu''' - Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto''' - Bow Shock interaction with Transient Solar Wind Structures<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner''' - Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu''' - Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi''' - Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu''' - Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto''' - Bow Shock interaction with Transient Solar Wind Structures<br /> <br /> ====Session 2: 03:30 pm - 05:00 pm on Wednesday (June 18) Foreshock and Magnetopause Phenomena ====<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner''' - Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu''' - Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi''' - Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu''' - Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto''' - Bow Shock interaction with Transient Solar Wind Structures<br /> <br /> ====Session 2: 03:30 pm - 05:00 pm on Wednesday (June 18) Foreshock and Magnetopause Phenomena ====<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner''' - Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu''' - Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi''' - Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu''' - Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto''' - Bow Shock interaction with Transient Solar Wind Structures<br /> <br /> ====Session 2: 03:30 pm - 05:00 pm on Wednesday (June 18) Foreshock and Magnetopause Phenomena ====<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

Zong, University of Massachusetts Lowell (qgzong@gmail.com)<br /> <br /> Michael Ruohoniemi, Virginia Polytechnic and State University (mikeruo@vt.edu)<br /> <br /> David Murr, Augsburg College (murrdl@augsburg.edu)<br /> <br /> ===Description===<br /> The &quot;Transient Phenomena at the Magnetopause and Bow Shock and Their Ground Signatures&quot; focus group will employ both observations and simulations to investigate the transient phenomena at the magnetopause and bow shock and their ground signatures. The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner''' - Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu''' - Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi''' - Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu''' - Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto''' - Bow Shock interaction with Transient Solar Wind Structures<br /> <br /> ====Session 2: 03:30 pm - 05:00 pm on Wednesday (June 18) Foreshock and Magnetopause Phenomena ====<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

<p>Hzhang: /* 2014 GEM Workshop Schedule */</p> <hr /> <div>===Chairs===<br /> <br /> Hui Zhang, University of Alaska Fairbanks (hzhang@gi.alaska.edu) <br /> <br /> Q.-G. Zong, University of Massachusetts Lowell (qgzong@gmail.com)<br /> <br /> Michael Ruohoniemi, Virginia Polytechnic and State University (mikeruo@vt.edu)<br /> <br /> David Murr, Augsburg College (murrdl@augsburg.edu)<br /> <br /> ===Description===<br /> The &quot;Transient Phenomena at the Magnetopause and Bow Shock and Their Ground Signatures&quot; focus group will employ both observations and simulations to investigate the transient phenomena at the magnetopause and bow shock and their ground signatures. The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner'''-Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu'''-Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi'''- Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu'''-Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto'''- Bow Shock interaction with Transient Solar Wind Structures<br /> <br /> ====Session 2: 03:30 pm - 05:00 pm on Wednesday (June 18) Foreshock and Magnetopause Phenomena ====<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2014 GEM Workshop Schedule===<br /> <br /> ====Session 1: 01:30 pm - 03:00 pm on Wednesday (June 18) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner'''-Particle acceleration in transient ion foreshock phenomena<br /> * '''Zixu Liu'''-Five-points THEMIS observations of multiple transient ion foreshock phenomena <br /> * '''Nick Omidi'''- Parametric Dependencies of Spontaneous Hot Flow Anomalies<br /> * '''Christina Chu'''-Analysis of Hot Flow Anomalies and Spontaneous Hot Flow Anomalies<br /> * '''Antonius Otto'''- Bow Shock interaction with Transient Solar Wind Structures<br /> <br /> ====Session 2: 03:30 pm - 05:00 pm on Wednesday (June 18) Foreshock and Magnetopause Phenomena ====<br /> * '''Q.-G.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2013 GEM Workshop Schedule===<br /> <br /> ====Session 1: 03:30 pm - 05:00 pm on Monday (June 17) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner'''-Foreshock bubbles and their effects on particle acceleration and the magnetosphere-ionosphere system<br /> * '''Nick Omidi'''- Mach number and cone angle dependence of SHFA formation.<br /> * '''Christina Chu'''-Statistical study of HFAs-THEMIS observations<br /> * '''Gabor Facsko'''-Turbulence in HFA cavities <br /> * '''Hui Zhang'''-Recent advances in HFA studies <br /> * '''Nick Omidi'''- Hybrid simulation of enhanced ion precipitation caused by an interplanetary shock<br /> <br /> ====Session 2: 10:30 am - 12:15 pm on Tuesday (June 18) Ground Signatures====<br /> * '''David Murr''' - Overview of ground mag signatures for event list on FG wiki<br /> * '''Michael Hartinger''' -Magnetospheric ULF waves driven by the ion foreshock<br /> * '''Harald Frey''' (presented by someone else) - Optical signatures<br /> * '''Mark Engebretson''' - EMIC waves stimulated by dayside transients<br /> * '''Hyomin Kim'''-Conjugate observations of traveling convection vortices and electromagnetic ion cyclotron waves associated with transient events at the magnetopause: Initial Results from the 40-Degree Magnetic Meridian Conjugate Magnetometer Network<br /> * '''Gar Bering''' - &quot;Further Studies of the Relationship between Pc3 Emissions and TCV's&quot;<br /> * '''Mark Engebretson''' -TCVs observed by MACCS array<br /> <br /> ====Session 3: 01:30 pm - 03:00 pm on Tuesday (June 18) Magnetopause Phenomena (joint with Reconnection FG)====<br /> * '''Rick Wilder'''-Cluster Observations of Reconnection Exhausts at the High-Latitude Magnetopause Under Extreme Density Asymmetry Conditions<br /> * '''Binzheng Zhang'''- Bifurcation of soft electron precipitation under IMF By driving conditions<br /> * '''Karlheinz J Trattner''' -Tracing multiple X-lines at the magnetopause<br /> * '''Yaireska M.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===2013 GEM Workshop Schedule===<br /> <br /> ====Session 1: 03:30 pm - 05:00 pm on Monday (June 17) Foreshock Phenomena==== <br /> <br /> * '''Drew Turner'''-Foreshock bubbles and their effects on particle acceleration and the magnetosphere-ionosphere system<br /> * '''Nick Omidi'''- Mach number and cone angle dependence of SHFA formation.<br /> * '''Christina Chu'''-Statistical study of HFAs-THEMIS observations<br /> * '''Gabor Facsko'''-Turbulence in HFA cavities <br /> * '''Hui Zhang'''-Recent advances in HFA studies <br /> * '''Nick Omidi'''- Hybrid simulation of enhanced ion precipitation caused by an interplanetary shock<br /> <br /> ====Session 2: 10:30 am - 12:15 pm on Tuesday (June 18) Ground Signatures====<br /> * '''David Murr''' - Overview of ground mag signatures for event list on FG wiki<br /> * '''Michael Hartinger''' -Magnetospheric ULF waves driven by the ion foreshock<br /> * '''Harald Frey''' (presented by someone else) - Optical signatures<br /> * '''Mark Engebretson''' - EMIC waves stimulated by dayside transients<br /> * '''Hyomin Kim'''-Conjugate observations of traveling convection vortices and electromagnetic ion cyclotron waves associated with transient events at the magnetopause: Initial Results from the 40-Degree Magnetic Meridian Conjugate Magnetometer Network<br /> * '''Gar Bering''' - &quot;Further Studies of the Relationship between Pc3 Emissions and TCV's&quot;<br /> * '''Mark Engebretson''' -TCVs observed by MACCS array<br /> <br /> ====Session 3: 01:30 pm - 03:00 pm on Tuesday (June 18) Magnetopause Phenomena (joint with Reconnection FG)====<br /> * '''Brian Walsh'''-Plasmaspheric drainage plumes and reconnection<br /> * '''Sunhee Lee'''-Cold ion behavior during magnetic reconnection at the magnetopause<br /> * '''Rick Wilder'''-Cluster Observations of Reconnection Exhausts at the High-Latitude Magnetopause Under Extreme Density Asymmetry Conditions<br /> * '''Binzheng Zhang'''- Bifurcation of soft electron precipitation under IMF By driving conditions<br /> * '''Karlheinz J Trattner''' -Tracing multiple X-lines at the magnetopause<br /> * '''Yaireska M.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010, [http://onlinelibrary.wiley.com/doi/10.1029/2009JA014828/abstract]]; Turner et al. [JGR, 2013, [http://onlinelibrary.wiley.com/doi/10.1002/jgra.50198/abstract]]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere.

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010]; Turner et al. [JGR, 2013]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.

The goal of this focus group is to provide a fundamental physical understanding of the transient phenomena at the magnetopause and bow shock including magnetic reconnection, FTEs, and Hot Flow Anomalies. This focus group encourages participation from communities interested in spacecraft observations (e.g., THEMIS and Cluster), ground-based observations (all-sky camera, radar, magnetometer), and global simulations. Coordinated multi-point observations are especially encouraged. This focus group is unique in the sense that it connects phenomena in regions ranging from the distant solar wind, bow shock, magnetosheath, and magnetosphere, all the way down to the ionosphere. Thus it will attract participation from a broad community including CEDAR and SHINE who do not normally interact.<br /> <br /> ===Comparison of Transient Phenomena at the Bow Shock===<br /> {| border=&quot;1&quot; Class=&quot;wikitable&quot;<br /> |-<br /> !!!

The kinetic processes associated with these phenomena modify the solar wind just prior to its interaction with the Earth's magnetosphere. <br /> <br /> '''Hot Flow Anomalies (HFAs)'''<br /> <br /> HFAs are marked by greatly heated plasmas and substantial flow deflections, with durations of a few minutes [e.g., Schwartz et al., 1985; Schwartz, 1995; Thomsen et al., 1986; Lucek et al., 2004; Facsko et al., 2008; Zhang et al., 2010; Wang, Zong, and Zhang, 2012]. HFAs are thought to be produced by the interaction of certain types of upstream discontinuities with the bow shock [Thomas et al., 1991; Wang, Zong, and Zhang, 2013]. The ions reflected from the bow shock are energized and trapped in the vicinity of the discontinuities when the motional electric field points toward the discontinuity. <br /> <br /> '''Spontaneous Hot Flow Anomalies (SHFAs)'''<br /> <br /> Description: SHFAs are similar to HFAs, though SHFAs occur independent of any discontinuity in the pristine, upstream magnetic fields. They form due to processes internal to the quasi-parallel foreshock, and display all of the same core and compression region characteristics as HFAs.<br /> Some Refs: Zhang et al [Under review, JGR]; Omidi et al. [JGR, 2013]<br /> <br /> '''Foreshock Bubbles (FBs)'''<br /> <br /> Description: FBs can form when energetic foreshock ions upstream of quasi-parallel planetary bow shocks interact with rotational discontinuities in the pristine, upstream IMF. Unlike HFAs, FBs form independent of any connection between the discontinuity and the bow shock. FBs form just upstream of the responsible discontinuity and move anti-sunward with it. As an FB impinges upon a planetary bow shock and sweeps up more and more energetic ions in the foreshock, it grows in time, potentially reaching sizes on the same order as Earth's entire dayside magnetosphere. Due to the building concentration of suprathermal ions in their cores, FBs exhibit very high core temperatures, resulting in the expulsion of thermal plasma, which drops the core density and field strength. Core fields are highly distorted, and within the core, there are very strong and sometimes even sunward bulk flow deflections. Compression regions form around the edges of the core, and provided sufficient conditions, the upstream compression regions can evolve into fast magnetosonic shocks (i.e., if the difference between the upstream bulk velocity and the rate at which the FB grows back into the upstream plasma approaches and exceeds the fast magnetosonic speed). FBs should be particularly efficient particle accelerators since they involve two converging shocks (i.e., that of the FB at the upstream edge and the bow shock itself) and increased wave activity in their cores. When a FB impacts the bow shock and magnetosphere, it should first result in expansion of the system into the tenuous core followed by a sudden and strong compression of the system due to the upstream shock/compression region. FBs can result in extreme magnetopause deformations and global magnetosphere-ionosphere activity. <br /> Some Refs: Omidi et al. [JGR, 2010]; Turner et al. [JGR, 2013]<br /> <br /> '''Foreshock Cavities'''<br /> <br /> Foreshock cavities, although more common, are less prominent than the HFAs in the sense that the solar wind distributions within the cavities show little evidence of heating or significant flow deflection although a second, suprathermal population is present. Foreshock cavities can be identified based on enhanced magnetic field strengths and densities bounding regions of depressed magnetic field strength and density containing a suprathermal ion component [e.g., Sibeck et al., 2002, 2004; Schwartz et al., 2006; Billingham et al., 2011]. <br /> Formation mechanism: Antisunward-moving slabs of magnetic field lines connected to the bow shock that are sandwiched between broader regions of magnetic field lines that remain unconnected to the bow shock. The slabs are filled with reflected and energized particles from the bow shock. The corresponding pressure enhancement causes the cavities to expand, depressing the internal densities and magnetic fields but enhancing these parameters at the expanding edge [Schwartz et al., 2006]. <br /> <br /> '''Foreshock Cavitons'''<br /> <br /> Foreshock cavitons are about an RE in size. Their cores exhibit drops in density and magnetic field, while their outer edges show plasma and magnetic field enhancements. They form as a result of the nonlinear evolution of two types of waves: the parallel propagating sinusoidal waves and the highly oblique, linearly polarized, fast magnetosonic waves [Lin, 2003; Lin and Wang, 2005, Omidi, 2007; Blanco-Cano et al., 2009, 2011]. Foreshock cavitons are embedded in regions with ULF activity, which is in contrast to the isolated character of foreshock cavities.<br /> <br /> '''Foreshock Compressional Boundary'''<br /> <br /> The foreshock compressional boundary (FCB) [Sibeck et al., 2008; Omidi et al., 2009] forms in the ion foreshock and is associated with enhanced densities and magnetic field strengths. Backstreaming ions result in increased pressure within the foreshock region leading to its expansion against the pristine solar wind and the generation of FCB. Although the FCB itself is associated with increases in the magnetic field strength and density, these quantities are reduced on the turbulent side of the FCB as compared to the pristine solar wind. FCBs may be a steady state feature, but observed transiently because of slight changes in the IMF orientation. <br /> <br /> '''Density Holes'''<br /> <br /> Similar to HFAs, density holes display significant bulk flow deflections and are filled with heated plasma. Density holes are accompanied by similarly shaped magnetic holes. They have enhanced densities and compressed magnetic field at one or both edges. Density holes have durations of ~18 seconds, which are much shorter than that of HFAs, and scale sizes of an ion gyroradius, which are much smaller than those of HFAs [Parks et al., 2006]. Density holes are possibly formed by backstreaming particles interacting with the original solar wind [Parks et al., 2006].<br /> <br /> '''Short, large-amplitude magnetic structures (SLAMS)'''<br /> <br /> SLAMS (Short, Large-Amplitude, Magnetic Structures) are large amplitude (the magnetic field magnitude is enhanced over the undisturbed field by at least a factor of 2.5) magnetic structures with durations of the order of 10 s [Schwartz, 1991; Lucek et al., 2002]. They grow rapidly (~seconds) out of ULF waves in the foreshock region. See also: Wilson III et al.
