GEM Focus Group "Substorm Expansion Onset: The First 10 Minutes": First Announcement for the GEM 2009 Summer Workshop ---------------------------------------------------------------------------- From: Shin Ohtani 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.

THEMIS Science Data Analysis Software Tutorial at GEM 2009 Summer Workshop ---------------------------------------------------------------------------- From: David King The THEMIS Project announces a Science Data Analysis Software Tutorial at the National Science Foundation's Summer 2009 GEM workshop at Snowmass Colorado. The Tutorial will be held on Friday June 26th from 10:30 - 12:15. The Tutorial will review the use of IDL command line analysis tools with emphasis on Plotting, Coordinate Transformations, Mapping tools and a new mini-language for operations on structures and tplot variables. It will be followed by presentation of the capabilities of the new Graphical User Interface (GUI). The new GUI features a user friendly windows-like environment, the ability to produce publishing quality plots and increased user interaction with graphics and visualization options. +-------------------------------------------------------------------------+ |To subscribe GEM Messengers, send an e-mail to | | with the following command in the body of your e-mail message: | | subscribe gem | |To remove yourself from the mailing list, the command is: | | unsubscribe gem | | | |To broadcast a message to the GEM community, please contact Peter Chi at | | | |Please use plain text as the format of your submission. | | | |URL of GEM Home Page: http://aten.igpp.ucla.edu/GemWiki | |Workshop Information: http://www.cpe.vt.edu/gem/index.html | +-------------------------------------------------------------------------+
