 From: Bob Lysak <bob@fields.space.umn.edu>
 Ion heating transverse to the magnetic field and the associated ion outflow are common processes in the polar and auroral regions of the Earth and the corona of the Sun.  The intent of this joint session is to bring together researchers in these areas and explore the similarities and differences between the two regions.  On Earth, these heating and outflow processes can be studied with in situ satellite and rocket data, as well as with energetic neutral atom imaging, while in the corona, remote observations from instruments such as the Ultraviolet Coronagraph Spectrometer on SOHO can be used to diagnose the properties of these ions.  Theory and modeling efforts have been carried out in both regions.  Despite the official title of the session, we solicit short contributions on observations, theory and modeling from either of these regions. The session will be held on Friday, June 27, from 10:30 am-12:15 pm.  Please contact Ben Chandran (benjamin.chandran@unh.edu) or Bob Lysak (bob@aurora.space.umn.edu) if you are interested in making a short, informal presentation.

+# How does reconnection depend on local plasma parameters (e.g., local magnetic field, density, resistivity) in global MHD simulations?
-During the 2008 Summer GEM workshop in Zermatt Utah, a number of sessions on the physical processes in the cusp will be held. The main objective of these sessions is to utilize observations, modeling, and theory of the cusp and its role in particle acceleration and plasma transport to assess the current status of the field and forge collaborative efforts towards addressing outstanding issues in the future. Based on the topics in earlier years and the discussions during the mini-workshop held during the 2007 Fall AGU, we plan to focus on the following topics:
+# What is the role of the Hall effect (and other kinetic scale physics) in magnetospheric reconnection?
-# Plasma transport into the cusp.
+'''Wed, June 25, 1:30 a.m. - 3:00 p.m.'''
-# Energization of ions in diamagnetic cavities.
+'''"How does the physics of magnetic reconnection scale up to reality?"'''
-It is the ultimate goal of the workshop to enhance our understanding of the cusp physics, its coupling to other parts of the system such as the bow shock, magnetopause and the ionosphere and the important role it plays in dayside transport and energization. Observational and theoretical contributions to this session are hereby solicited.
+This session will focus on the question of whether the physics of magnetic reconnection observed in kinetic scale simulations is relevant on a larger scale (hundreds of ion inertial lengths).  In particular, we would like to discuss the recent open boundary condition PIC simulation results, which seem to be at odds with the "standard model" of Hall-MHD reconnection.
-Those interested in these topics are invited to attend and contribute through showing a few slides and/or participation in the discussions.  Information regarding hotel reservations and travel arrangements will be posted on the GEM website (http://www.cpe.vt.edu/gem) in the near future.  Those wishing to give a presentation or with questions regarding the workshop should contact the conveners trattner@mail.spasci.com, omidi@solanasci.com or david.g.sibeck@nasa.gov.
+We are going for an informal group discussion, but short presentations on the topics listed above are welcome.  Please email John Dorelli (john.dorelli@unh.edu) or Mike Shay (shay@udel.edu) if you would like to participate.

 The 2008 GEM workshop will herald a new Tail Focus Group, "Modes of solar wind-magnetosphere energy transfer." This focus group seeks to improve our knowledge of the physical mechanisms that provide for different dynamical modes of response of the magnetotail to the solar wind. The Focus Group proposal is available at

 We are pleased to announce the start of a new focus group, "Expansion Onset: The First 10 Minutes", at the upcoming GEM workshop in Zermatt Utah. This focus group is concerned with magnetospheric and ionospheric processes around the time of substorm onset, and expects to address key physics questions regarding those processes, using ground imagery, magnetometry and in situ observations from the THEMIS, Geotail, FAST, Cluster and other satellite missions, as well as theory and modeling of processes before/during the expansion phase onset. The tentative plan is available at:

 In order to communicate our ideas better we will need tangible examples. Several nice events identified from the last THEMIS tail season can serve that purpose quite well. If there are suggestions for any events from the community please relay them to the conveners. A consolidated list of events will be announced in the near future. There will be 3 GEM meeting break-out sessions regarding this focus group, on Wed. June 25, at 10:30-12:15, 1:30-3:00 and 3:30-5pm. The discussion will start with a speaker presenting the questions at hand and is expected to be followed by event expositions but also theory/modeling related discussions.

 The Diffuse Auroral Precipitation and Near Earth Magnetosphere focus groups are holding a combined session on "Plasma sheet ion scattering."  The plasma sheet and magnetic field structure are tightly coupled.  The plasma pressure stretches the field lines, which leads to current sheet scattering of ions into the atmosphere where they excite the diffuse ion aurora.  The equator-ward edge of the diffuse aurora can provide valuable information on the magnetic structure in the magneto-tail.  Ion precipitation can also be associated with features of the ring current. The plasma sheet ion scattering session will focus on theory, modeling and observations of the plasma sheet, magneto-tail structure and the diffuse ion aurora.
