New GEM Focus Group "Modes of Solar Wind-Magnetosphere Energy Transfer"
----------------------------------------------------------------------------
From: Larry Kepko <larry.kepko at unh.edu> and
      Bob McPherron <rmcpherron at igpp.ucla.edu>

The 2008 GEM workshop will herald a new Tail Focus Group, "Modes of solar 
wind-magnetosphere energy transfer." This focus group seeks to improve our 
knowledge of the physical mechanisms that provide for different dynamical 
modes of response of the magnetotail to the solar wind. The Focus Group 
proposal is available at

http://www.spaceplasma.unh.edu/~jraeder/GEM/uploads/Main/GEM-FGProposal-2007-McPherron-response.pdf

At the upcoming workshop we will discuss:
 - Steady magnetospheric convection
 - Sawtooth events
 - Poleward Boundary Intensifications
 - Pseudo breakups

The discussion of each topic will start with a short invited talk designed 
to lay the groundwork for discussion. Each invited speaker will describe:
 - The particular state of solar wind conditions associated with the 
   response mode
 - The internal state of the magnetosphere during the response mode
 - What causes the transition into or out of a mode

Anyone interested in participating in the discussion are encouraged to email 
Larry Kepko (larry.kepko at unh.edu) or Bob McPherron (rmcpherron at 
igpp.ucla.edu).
