GEM will be holding its annual summer workshop June 21-26, 2009 at the Snowmass Conference Center in Snowmass, Colorado. Registration can be made at the GEM Workshop Web Site by June 14, 2009. The GEM Workshop Web Site also provides the workshop agenda.

The following GEM sessions are calling for presentations. Poster titles must be submitted to the workshop website no later than Friday, June 12.

Substorm Expansion Onset: The First 10 Minutes

This is the 1st announcement of the focus group "Expansion Onset: The First 10 Minutes" for the upcoming GEM workshop in Snowmass (June 21-26, 2009; http://www.cpe.vt.edu/gem/index.html).

We will have 4 breakout sessions on June 25 (Thu) and 26(Fri) (for the current schedule of the overall workshop see http://www.ece.vt.edu/GEM-2009).

Following are four topics and primary questions we will discuss this year.

1) Onset Timing What is the time sequence of onset-related phenomena observed in space and on the ground, and what are the implications for substorm initiation?

2) M-I Coupling How does aurora evolve around substorm onsets? How are magnetospheric and ionospheric onset signatures connected in terms of auroral precipitation and currents, and what can we learn about substorm initiation from simultaneous ground-satellite observations?

3) Onset Signature Propagation How do onset-related signatures propagate in the magnetosphere? How does the uncertainty of propagation time affect our understanding of substorm initiation?

4) Mapping How does the presence and evolution of pre-onset and expansion-phase current systems affect the link between auroral and plasma sheet locations and processes?

Sessions will be scheduled based on responses to this announcement. Those who are interested in participating in the discussion are encouraged to email to Andrei Runov (arunov at igpp.ucla.edu), the session coordinator, with c.c. to other conveners.

We look forward to seeing you there.
