1. Call for Participation at 2010 GEM Summer Workshop:
   Substorm Expansion Onset: The First 10 Minutes
----------------------------------------------------------------------
From: Vassilis Angelopoulos (Vassilis at ucla.edu)
      Kazuo Shiokawa (Shiokawa at stelab.nagoya-u.ac.jp)
      Andrei Runov (arunov at igpp.ucla.edu)
      Shin Ohtani (Ohtani at jhuapl.edu)

Our focus group, "Substorm Expansion Onset: The First 10 Minutes", 
will have 4 sessions at the upcoming GEM Workshop in Snowmass (June 
20-25, 2010).  They are scheduled on June 24 (Thu) and 25 (Fri).  We 
have four topical areas identified, which are:

1. Onset timing: observations/theory/simulations (Angelopoulos)
2. How do onset signatures propagate to near Earth and to the ground? 
(Runov)
3. Ground-space mapping of physical processes before/during/after 
onset (Ohtani)
4. Substorm processes near transition between stretched and dipole 
field lines (Shiokawa)

We would like to invite you to participate, and if you have any 
request or question, please contact the person of the topical area of 
your interest, whose name is in the parentheses for each topic.
