The GEM Substorm Trigger Observational Working Group at GEM Mini-Workshop
-------------------------------------------------------------------------
From: Aaron Ridley (ridley at umich.edu)

The GEM Substorm Trigger Observational working group would like to invite 
presentations and discussions focused on a limited number of substorms at
the GEM Miniworkshop.  The working group has started to focus on describing
a limited number of substorms thoroughly.  The times in interest are (but
are not specifically limited to):

January  7, 1997  0300 UT
January  7, 1997  1730 UT
January 12, 1997  0730 UT
January 27, 1997  1630 UT

Presentations describing the basic characteristics of each event in
various data sets (UVI, VIS, SuperDARN, AMIE, Geotail, Geosynchronous
particles, etc.) will be presented.  Presentations describing how these
events do or don't fit current theories of substorm onsets are welcome.

Please contact Aaron Ridley (ridley at umich.edu) or Larry Kepko
(lkepko at igpp.ucla.edu) if you are interested in presenting data, simulation
results, or specific views on these events at the GEM Miniworkshop.
