1. 2015 Mini-GEM Session: Ultra-Large International Terrestrial Magnetometer Array (ULTIMA)
------------------------------------------------------------
From: Ian Mann (imann at ualberta.ca) and Peter Chi (pchi at igpp.ucla.edu)

The Ultra-Large International Terrestrial Magnetometer Array (ULTIMA) is a consortium of magnetometer arrays promoting the community-wide exploitation of data from multiple international networks of ground-based magnetometers. In particular ULTIMA promotes the coordinated operation of the arrays and promotes data use from multiple arrays in support of solar-terrestrial physics and space weather science and applications, especially in combination with data from satellite missions.

We invite everyone who is interested in the use of magnetometer data, especially in support of mission such as THEMIS, Van Allen Probes, Cluster, e-POP, Swarm, MMS and others to join us for two sessions focussing on science as well as operations.

This year the ULTIMA session will focus partly on the scientific exploitation of ground-based magnetometer data in especially combination with such missions and hence is relevant to GEM-wide activity relevant for all GEM FGs.

Note the ULTIMA Meeting will take place from 9am-12 noon on Sunday 13th December, and hence will not clash with any GEM FG meetings since these all take place later in the day starting at noon.

The ULTIMA session will be held in the Gold Rush A room at the Holiday Inn Golden Gateway (1500 Van Ness) and will include science and array update talks as well as discussion on mechanisms for enhancing collaboration and on data and data analysis tool sharing.

If you would like to make a science or data presentation please let us know with a title and authors to Peter Chi (pchi at igpp.ucla.edu) and Ian Mann (imann at ualberta.ca) ideally by 5pm MST on Thursday 10th December and we will add it to the schedule. 

Current list of invited science speakers/topics (more welcome):

•	Kyle Murphy/NASA GSFC: FAC and Substorm Dynamics with Global Magnetometer Arrays and AMPERE
•	David Murr/Augsburg: ULF waves in GPS and magnetometer data
•	Jesper Gjerloev/Shin Othani/APL: ULTIMA Data Access and Science with SuperMAG: Current operations and future plans
•	Eija Tanskanen/FMI: Substorm Zoo for science and social data analysis

As usual there will also be updates on the latest scientific activities in the magnetometer array members of ULTIMA from science and operations talks and updates from ULTIMA Member teams.

2. 2015 Mini-GEM Session: Metrics and Validation (M&V) Focus Group
------------------------------------------------------------
From: Lutz Rastaetter (lutz.rastaetter at nasa.gov)

The Metrics and Validation Focus group is ending in 2015 and is organizing its last meeting at the 2015 GEM mini workshop.

Time: 12:00 noon - 1:30 PM, December 13, 2015
Location: Nevada Room, Holiday Inn Golden Gateway Hotel (1500 Van Ness Avenue)

This session will provide continuity as new focus groups are being proposed that will continue efforts started in the M&V focus group:
•	ULF Wave modeling – Kazue Takahashi, Michael Hartinger, Brian Kress
•	Modeling Methods and Validation – Mike Liemohn, Rob Redmon, Lutz Rastaetter, Katie Garcia-Sage

During this session we provide updates on ongoing challenges:
•	ULF wave modeling challenge; runs performed at the CCMC – Lutz Rastaetter
•	Magnetopause standoff modeling – Yaireska Collado-Vega

We also invite workshop style contributions on modeling and validation.

3. 2015 Mini-GEM Session: Inner Magnetosphere Cross-Energy/Population Interactions Focus Group
------------------------------------------------------------
From: Yiqun Yu (yiqunyu17 at gmail.com), Colby Lemon, Mike Lemon, Jichun Zhang

We would like to solicit short presentations relevant to mini-GEM session "The Inner Magnetosphere Cross-Energy/Population Interactions (IMCEPI)" to be held on Sunday Dec 13, 2015 in San Francisco.

Time and Location: 
15:30-17:00, Gold Rush B Room, Holiday Inn Golden Gateway Hotel, San Francisco.

We will focus on three challenge events to understand the coupling mechanisms in various regions,including wave-particle interactions in the inner magnetosphere, coupling between mid-tail and inner regions, as well as coupling between inner region and the ionosphere.
-- Feb 18-22, 2014: CME impact, prolonged storm main phase
-- March 17, 2013: Small storm, isolated clean substorm injections
-- Jan 25-26, 2013: Large storm, substantial substorm injections

We also welcome studies on other events/statistical results. If you are interested in presenting, please email Yiqun Yu with the title. We look forward to seeing your participation!

4. 2015 Mini-GEM Session: Tail-Inner Magnetosphere Interactions (TIMI) Focus Group
------------------------------------------------------------
From: Vassilis Angelopoulos (toffo at rice.edu), John Lyon, Pontus Brandt and Frank Toffoletto

On behalf of the GEM Tail-Inner Magnetosphere Interactions (TIMI) focus group, we would like to invite you to make a brief, informal presentation at this year’s GEM mini workshop on a topic related to this focus group. Part of the session will be for the purposes of planning the 2016 summer workshop, which will be the last year for this focus group.

The session will be held in the California room at Holiday Inn Golden Gateway, San Francisco on December 13, 2015 from 12-1:30 PM and your participation would be most welcome.

If you would to make presentation, please email Frank Toffoletto (toffo at rice.edu). 

We look forward to seeing you all in San Francisco.

5. 2015 Mini-GEM Session: Geospace Systems Science Focus Group
------------------------------------------------------------
From: Joe Borovsky (jborovsky at spacescience.org)

The Geospace Systems Science Focus Group is holding a planning session at Mini-GEM at 1:50 in the Washington room. We would like feedback and suggestions for the 2016 Summer GEM planning. Two potential sessions for Summer GEM to be discussed at Mini-GEM are:

1. Driver Geoeffectiveness and Geospace System Response
2. System-Level Data Analysis Tools and Techniques.

Brief presentations have been arranged to prime the pump of discussion on these two topics. Opinions welcome.
