1. Mini-GEM 2018: Conductance Challenge Joint Session
------------------------------------------------------------
From: Katherine Garcia-Sage, Hyunju Connor, Mike Liemohn, Lutz Rastaetter, Rob Redmon (katherine.garcia-sage at nasa.gov)

Please join us for the Conductance Challenge session at mini-GEM! This is a joint session with the Modeling Methods and Validation FG and the Magnetosphere-Ionosphere-Thermosphere (MIT) Coupling FG. The focus is on discussion of conductance and conductivity-related observations, modeling, and model-data comparisons for the following 4 events:

2016 Oct 13-15
2013 March 17
2015 Jun 21-24
2012 March 9

If you have recently made any improvements to your conductance modeling or auroral region data availability, we hope you'll attend! The session will be at 3:30 pm.

Confirmed presenters so far include:
Agnit Mukhopadhyay
Margaret Chen
Bob Robinson
Gang Lu - presented by Hyunju Connor

Contact Katherine Garcia-Sage (katherine.garcia-sage at nasa.gov) or Hyunju Connor (hkconnor at alaska.edu) for more info.

2. Mini-GEM 2018: The Tail Environment and Dynamics at Lunar Distances Focus Group Session
------------------------------------------------------------
From: Chih-Ping Wang, Andrei Runov, David Sibekc, Slava Merkin, Yu Lin (cat at atmos.ucla.edu)

The Tail Environment and Dynamics at Lunar Distances Focus Group will hold a session at the Mini-GEM workshop.

Time: 3:30-5:00 PM, Sunday, December 9, 2018
Location: Jefferson Room, Hilton Alexandria Old Town in Alexandria, Virginia

The 90 minute session will include two parts: 
(1) Progress on the topics of this FG: We would like to solicit short (< 5 min) GEM-style presentations of your current work on observations and modeling of structure, dynamics, and boundary processes in the mid-tail magnetosphere and magnetosheath. Topics related to near-Earth tail are also welcomed.

(2) Modeling challenge: We will present a modeling challenge event, 06-11 UT of 2017-07-09, for understanding the global response of the tail, from near-Earth to mid-tail, to a gradual solar wind dynamic pressure increase, an IMF southward turning, and an IMF northward turning. This is an midnight conjunction event of Arase(ERG), GOES, Geotail, MMS, and ARTEMIS. The observations will be compared with the BATS-R-US, OpenGGCM, and LFM runs conducted on NASA CCMC.

If you would like to present, please contact Chih-Ping Wang (cat at atmos.ucla.edu)
