(Jacob Bortnik, Craig Kletzing,Scot Elkington and Yuri Shprits)

You can submit the title of your presentation online by following the
link below to reserve a time slot during each individual session. We
invite potential contributions and encourage to limit presentations to
approximately 5 min.

Please submit the title of your presentations by June 5th at

In particular we would like to encourage modelers to participate in
the GEM particle modeling challenge. Data for the GEM chellange and
rules are given on ViRBO web site at

2. Call for Presentations at 2012 GEM Summer Workshop:
   Magnetosheath Studies Focus Group
----------------------------------------------------------------------
From: Steven Petrinec <steve.petrinec at gmail.com> and 
      Katariina Nykyri <nykyrik at erau.edu>

The Magnetosheath Focus Group will hold three sessions at the 2012 GEM 
Summer Workshop in Snowmass, CO (6/18; 10:30–12:15 & 13:30–15:00, and 
6/19; 10:30-12:15). We cordially invite participants to provide short 
presentations related to any of the magnetosheath focus group topics 
listed below. We especially encourage data-analysts utilizing in-situ 
spacecraft measurements from the THEMIS, Cluster and Geotail missions, 
as well as theoretical modelers, global and local modelers to 
participate in this session. We also welcome magnetosheath study 
presentations relevant to other solar system bodies, as they relate to 
the terrestrial magnetosheath. Please send the title of your 
presentation to us by June 8th.

The Primary Objectives and Expected Activities of the FG:

1. To produce more comprehensive models of large scale magnetosheath 
flow and field patterns, and geometry of the magnetosheath region

2. To improve understanding of magnetosheath plasma instabilities and 
wave particle interactions: Spatial distribution and characteristics

3. To develop a better understanding of the effects on magnetospheric 
dynamics due to processes occurring in the magnetosheath and due to 
characteristic magnetosheath properties.
