1. Tail\Modes of Solar Wind-Magnetosphere Energy Transfer Focus Group:
   Call for Presentations at the 2013 GEM Summer Workshop
----------------------------------------------------------------------
From: R. McPherron <rmcpherron at igpp.ucla.edu>
      J. Kissinger <jenni.kissinger at nasa.gov>
      L. Kepko <larry.kepko at nasa.gov>

The Focus Group on "Modes of Solar Wind-Magnetosphere Energy Transfer" 
will hold two sessions at the 2013 workshop. These sessions are 
scheduled at 10:30 AM to 12:15 PM and 1:30 to 3:00 PM on Thursday June 
20. The Focus Group has examined the solar wind and magnetospheric 
conditions leading to different types of geomagnetic activity. This 
will be the last meeting of this Focus Group as GEM moves to other 
topics. We will begin with a review of our past activities and 
suggestions for future work. We are soliciting presentations related 
to the following topics:

1.    The occurrence of substorms as function of universal time, 
season, and solar cycle
2.    The properties of steady magnetospheric convection (SMC) and its 
relation to solar wind and prior substorm activity
3.    The occurrence and properties of sawtooth events
4.    The occurrence statistics of poleward boundary intensifications 
(PBI) during substorm phases and SMC
5.    A comparison of PBI and pseudo breakups

Please contact one of the organizers if you have material you wish to 
present. Plan for short informal presentations designed to stimulate 
discussion.

2. Plasmasphere-Magnetosphere Interaction Focus Group:
   Call for Presentations at the 2013 GEM Summer Workshop
----------------------------------------------------------------------
From: Joe Borovsky <jborovsky at spacescience.org>, Jerry Goldstein, 
      and Maria Spasojevic

The "Plasmasphere-Magnetosphere Interaction" focus group will have its 
final sessions at the 2013 GEM Summer Workshop in Snowmass June 16-21. 
Two sessions will be held on Tuesday Afternoon: one session in which 
plasmaspheric research findings from this last year will be reported, 
and one session that is a wrap-up/summary of progress made with the 5-
year Focus Group. To make short contributions to either session, 
please contact Joe Borovsky (jborovsky at spacescience.org).

3. The Scientific Magnetic Mapping and Techniques Focus Group:
   Call for Presentations at the 2013 GEM Summer Workshop
----------------------------------------------------------------------
From: Elizabeth MacDonald <macdonald at lanl.gov>, 
      Robyn Millan <robyn.millan at dartmouth.edu>, and 
      Eric Donovan <edonovan at ucalgary.ca)

The GEM Magnetic Mapping Focus group (bit.ly/gem_mapping) is pleased 
to announce our sessions for Snowmass 2013:

* Monday at 10:30 in Salon D 
* Monday at 1:30 in Salon D 

We will focus the first two sessions on mapping challenges around a 
number of new exciting events in the RBSP era including:

Nov 14 (lobe crossings)
Jan 17, Jan 26, Feb 2 (BARREL and RBSP wave conjunctions)
Mar 17 (geomagnetic storm)

Coordinated study from multiple observation types and vantage points 
is encouraged and those who wish to present on other dates of interest 
are also welcome. Invited and confirmed speakers include Toshi 
Nishimura, Lutz Rastaetter, Alexa Halford, Phil Erickson, and Mei-
ching Fok. 

* Finally, Tuesday at 10:30 in Salon D we will continue our successful 
collaboration with the Substorm Expansion Onset focus group. 

Those interested in volunteering for any of these exciting, 
challenging topics, please contact Liz MacDonald, Robyn Millan, and/or 
Eric Donovan at your earliest convenience. We look forward to seeing 
you in Snowmass and thank you in advance for your participation.
