		+
		+	====Tuesday 6/20, PM1 - 1:30-3:00pm (individual session)====
		+
		+	This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any topic relevant to the focus group as interest dictates. Please contact Brian Walsh <bwalsh at bu.edu> with questions.
		+
		+	====Wednesday 6/21, PM1 - 1:30-3:00pm (individual session)====
		+
		+	This session will be a continuation of the open forum from Tuesday. We also would like to spend some time discussing community interest in proposing a new reconnection focus group. Discussion on topics for the next group to address are invited, as this is a grass roots effort. Please contact Yi-Hsin Liu <Yi-Hsin.Liu at Dartmouth.edu> with questions.
		+
		+	====Thursday 6/22, PM2 - 3:30-5:00pm (Joint session with “Dayside Kinetic Processes in Global Solar Wind - Magnetosphere Interaction” focus group)====
		+
		+	This session will focus on discussing the following science topics: 1) Kinetic physics of dayside and/or magnetosheath reconnection - dissipation, energy conversion, particle acceleration, and comparisons between the two regions, 2) Do kinetic bow shock and magnetosheath transients impact magnetopause reconnection?, and 3) Does kinetic physics at the dayside impact the global reconnection process? Discussion on other topics related to the two focus groups is welcome.
		+
		+	We plan to have most of the time driven by discussion. Time permitting, we would like community members to pose a science question or challenge that they would like to see other people address (e.g., “is it possible to observe/simulate this feature I’ve simulated/observed?”). We would also like to have time to brainstorm on open questions. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> or Heli Hietala < heli at igpp.ucla.edu> with questions.

		+	===2016 GEM Workshop Plans===
		+
		+	We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Workshop.
		+
		+	We have a broad collection of sessions planned for this year, including both basic reconnection science and joint sessions with focus groups where reconnection plays a role in the broader dynamics. The sessions are intended to be driven by open discussion, but attendees are encouraged to enhance the discussion by showing a slide or two as appropriate. As in the past, we are asking participants to not do AGU-style presentations. As always, we will try to accommodate all who want to speak, but the priority is having open and active discussion over sticking to a schedule. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.
		+
		+	The (currently scheduled) dates, times, and summaries for each session are:
		+
		+	====Monday 6/20, PM1 - 1:30pm-3:30pm (Individual session)====
		+
		+	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. In addition, we will have a discussion of magnetotail stability, with a scene setting talk on recent progress (Slava Merkin, JHU-APL). We also encourage discussion on other relevant topics. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you are interested in being part of the discussion.
		+
		+	====Monday 6/20, PM2 - 4:00pm-6:00pm (Joint with Mesoscale Auroral and Polar Cap Dynamics and Substorms focus groups)====
		+
		+	We will discuss the following topics:
		+
		+	-- Ionospheric signatures of magnetopause reconnection and FTEs
		+	-- Possible dayside-nightside coupling (remote observations, modeling, tests for in-situ multi-point observations)
		+	-- The role of the ionosphere in transient day- and night-side reconnection-related processes
		+
		+	Contributions from ground- and space-based observers as well as from modelers are welcome. Please contact Brian Walsh <bwalsh at bu.edu> if you are interested in being part of the discussion.
		+
		+	====Tuesday 6/21, PM1 - 1:30pm-3:30pm (Joint with Dayside Kinetic and Transient Phenomena focus groups)====
		+
		+	This session will encourage cross-focus group interaction and open ended discussion on the topics of magnetopause reconnection, flux-transfer events, Kelvin-Helmholtz instability, magnetopause waves, and other boundary layer processes. Talks on MMS-related studies and modeling with the emphasis on global magnetospheric aspects of reconnection are especially encouraged. Please contact Yi-Hsin Liu <yi-hsin.liu at nasa.gov> by Friday, June 10 if you are interested in being part of the discussion.
		+
		+	====Friday 6/24, PM1 - 1:30pm-3:30pm (Individual session)====
		+
		+	This session will be an open forum for discussion of topics about reconnection in the magnetosphere. It may include discussion from any of the earlier sessions as interest dictates. In addition, there will be an update on efforts to incorporate kinetic modeling into NASA’s CCMC. We also hope there is time for a discussion on topics of interest for next year, and the potential future of the reconnection focus group beyond when the current version ends next year. Please contact Paul Cassak <Paul.Cassak at mail.wvu.edu> if you would like to offer a discussion topic.
		+
		+	We look forward to seeing you at the sessions! Please let one of the organizers know if you have any comments, questions or suggestions.

		+
		+	We are announcing plans for the "Magnetic Reconnection in the Magnetosphere" Focus Group sessions at the upcoming GEM Meeting. We also welcome Yi-Hsin Liu and Brian Walsh to our team of co-chairs, and offer thanks to Homa Karimabadi for his years of service.
		+
		+	Last year, we employed two "scene setting" talks per session to frame relevant questions and generate discussion for the remainder of the session. We intend to use a similar strategy this year. We are in the process of lining up speakers, but if you would like to nominate someone (including a self-nomination) for any of the sessions listed below, please email Paul.Cassak at mail.wvu.edu with the name(s) and a brief justification.
		+
		+	Others are encouraged to enhance the discussion by showing a slide or two as appropriate, and we expect some time for open discussion. As in the past, we are asking participants to not do AGU-style presentations, opting for discussion and real-time progress instead. We strongly encourage anyone wishing to present more than a few slides to also sign up to give a poster.

		+
		+	====Tuesday 6/16, 1:30pm-3:00pm (Joint with "Tail-Inner Magnetosphere Interactions" Focus Group)====
		+
		+	This session will focus on reconnection in the magnetotail and its effects on the inner magnetosphere. In particular, a topic that has generated a lot of interest of late are the kinetic processes associated with energy conversion and the formation and consequences of dipolarization fronts. We also encourage discussion on reconnection onset in the magnetotail - tearing vs. ballooning/interchange. Other relevant topics are welcome.

		+	====Thursday 6/18, 1:30pm-3:00pm (Joint with "Geospace System Science"Focus Group)====
		+
		+	This session will encourage cross-focus group interaction and open ended discussion on the topic of "What is the interplay between local and global processes in regulating reconnection?" This can include local-scale (Alfven speeds, microphysics, plasma state and composition, magnetic field geometry), meso-scale (geometry of the magnetic configuration, impediment of outflows), and global-scale (magnetospheric geometry and inflation, current closure through the magnetosheath, ionospheric conductivity, ionospheric outflows). We expect observers, theorists, and modelers interested in the magnetosphere as a system will find this session interesting.
		+
		+	====Thursday 6/18, 3:30pm-5:00pm (Individual session)====
		+
		+	This session will be an open forum for discussion of topics about reconnection in the magnetosphere. We expect dayside reconnection to be a main topic of this session. We encourage discussion on topics of local vs. global control of dayside reconnection and the role of diamagnetic effects and flow shear on dayside reconnection. We encourage people interested in opening a discussion on a topic (the ones listed or otherwise) to attend. Please email Paul.Cassak at mail.wvu.edu by June 9 if you would like to propose a discussion topic.
