1. Call for Presentations at 2010 GEM Summer Workshop:
   "The Modes of Magnetospheric Response" Focus Group
----------------------------------------------------------------------
From: Larry Kepko <Larry.kepko at nasa.gov> and 
      Bob McPherron <rmcpherron at igpp.ucla.edu>

The Modes of Magnetospheric Response focus group will hold three 
sessions at the upcoming GEM Workshop (June 20-25) in Snowmass, CO, 
covering the following topics:

1. Dayside observations during sawtooth events, the role of polar cap 
saturation, and implications for the magnetospheric response. 
Specifically, are particle injections on the dayside dispersionless or 
dispersive? Can sawtooth observations be understood as substorms that 
penetrate deep into the inner magnetosphere, or do sawtooth represent 
a fundamentally different state of the magnetosphere? We particularly 
encourage participants to bring data that addresses the issue of 
dayside injection and/or dipolarization.

2. Non-linear coupling and the role of pre-conditioning in determining 
the response mode. Example topics and questions include: Systematic 
errors in activity indices; Seasonal effects on coupling functions; 
mass-loading effects on convection; The storm/substorm/SMC 
relationship.

3. Magnetospheric response and solar wind energy transfer during the 
extreme solar minimum.

This focus group has as its aim the improvement of knowledge of the 
physical mechanisms that provide different dynamical modes of response 
of the magnetotail to the solar wind. These include substorms, steady 
magnetospheric convection, sawtooth injection events, pseudo breakups, 
and poleward boundary intensifications. A complete description of the 
FG and its goals can be found at http://bit.ly/beGmTF

2. Call for Presentations at 2010 GEM Summer Workshop:
   "Plasma Entry and Transport into and within the Magnetotail (PET)"
   Focus Group
----------------------------------------------------------------------
From: Antonius Otto <ao at how.gi.alaska.edu>,
      Jay R. Johnson <jrj at pppl.gov>, and
      Simon Wing <Simon.Wing at jhuapl.edu>

We would like to invite contributions to the PET focus group at the 
upcoming GEM workshop in Snowmass on June 21-25, 2010.  The sessions 
will be held in a workshop (NOT AGU) style in which each speaker will 
be allotted time for a 2-3 slides, in order to ensure enough time for 
discussion.  In order to encourage this, at least one of the slides 
should deal with unresolved issues.  Speakers are encouraged to end 
the presentation with outstanding questions rather than a summary of 
what has/have been accomplished.  It is expected that there will be 
three sessions:
(1) ion outflow effects on the plasma sheet;
(2) Constraints on plasma sheet entry and transport; and
(3) GEM challenge, northward and southward IMF.

All three sessions have been tentatively scheduled on Monday Jun 21 
(See http://www.cpe.vt.edu/gem/index.html for the definitive schedule).  
If you have not already done so, please send the title(s) and 
session(s) of your contribution(s) to us at your earliest convenience 
at the email addresses listed below.
