1. Dates and Locations of the GEM Summer Workshop 2017
------------------------------------------------------------
From: Zhonghua Xu (zxu77 at vt.edu)

As the decision of GEM steering committee decided, we will hold the GEM Summer Workshop 2017 at Renaissance Portsmouth-Norfolk Waterfront Hotel, Portsmouth, during June 18 - 23, 2017.

More information will be updated to the GEM 2017 website after the GEM-Mini Workshop 2016, which will be held at the Holiday Inn Golden Gateway in San Francisco on Dec 11, 2016, the Sunday right before the AGU Fall Meeting.

For any questions related to the GEM workshop, please feel free to contact Zhonghua Xu at zxu77 at vt.edu.

2. 2016 GEM-CEDAR Workshop Report: Tail Inner Magnetosphere Interactions (TIMI) Focus Group
------------------------------------------------------------
From: Frank Toffoletto, Vassilis Angelopoulos, Pontus Brandt, and John Lyon (toffo at rice.edu)

The GEM Tail Inner magnetosphere interactions (TIMI) had its final session at the 2016 GEM workshop in Santa Fe NM. Katie Garcia-Sage, presented some recent work she has done examining the stability under tearing and interchange of LFM simulations using a criteria based on the work of Lembege and Pellat [1982]. They found in some cases the code could be unstable to tearing near the Earth and possible also to interchange. W. D. Cramer presented work using the OpenGGCM-RCM code to investigate to simulate multiple geomagnetic storms with a variety of solar wind driving conditions and correlate the various mechanisms with changes in ring current-generated geomagnetic disturbance. Under this analysis they found that changes in ring current geomagnetic disturbance correlate better with steady convection than occurrence of fast flows. Christine Gabrielse analytically modeled localized dipolarizing flux bundles/bursty (DFB) bulk flows to demonstrate their ability to create both dispersionless and dispersed injection signatures at multiple spacecraft simultaneously. She demonstrated that the localized nature of the DFB results in localized, sharp magnetic field gradients that give energetic electrons a boost earthward on the DFB's dawnside (from gradB drift), but cause electrons to gradB drift tailward on the duskside (which can result in flux decrease at the front's duskside). The B gradients allowed electrons to travel earthward all the way from the reconnection site, but she also noted that much of the injection's electron population may originate in the plasma sheet before encountering the DFB. Finally, Jiang Lu report that dipolarizing flux bundles can send traveling Pi2 waves deep inside the plasmasphere, but these waves did not cause significant change to the energy spectrum there.

3. NASA ROSES-16 Final Text for MMS GI
------------------------------------------------------------
From: Errol J. Summerlin (errol.summerlin at nasa.gov)

This message is to inform you that the final text for program element B.8 Magnetospheric Multiscale Guest Investigators (MMS GI) has been released and is now available on NSPIRES.

The Heliophysics Guest Investigators (H-GI) program is a component of the Heliophysics Research Program. This particular element of the Guest Investigator program is offered only for investigations that primarily use data from the recently launched Magnetospheric Multiscale (MMS) Mission.

This particular ROSES element supports investigations whose primary focus is the analysis of MMS data. Proposals should use primarily MMS data to address (1) the goals of the MMS mission (found at http://mms.gsfc.nasa.gov/about_mms.html) or (2) any of the relevant goals of the Heliophysics Decadal survey (Solar and Space Physics: A Science for a Technological Society http://www.nap.edu/catalog.php?record_id=13060):

1. Determine the origins of the Sun’s activity and predict the variations in the space environment;
2. Determine the dynamics and coupling of Earth’s magnetosphere, ionosphere, and atmosphere and their response to solar and terrestrial inputs; 
3. Determine the interaction of the Sun with the solar system and the interstellar medium;
4. Discover and characterize fundamental processes that occur both within the heliosphere and throughout the universe.

This program is intended to maximize the scientific return from this recently launched mission by providing support for research of a breadth and complexity beyond presently funded investigations. As for any H-GI proposal, investigations may employ theory, models, and data from other sources, as needed, to interpret and analyze NASA’s MMS data, but only as a secondary emphasis.

Step-1 proposals are due November 18, 2016, and Step-2 proposals are due January 13, 2017.

The solicitation can presently be found in the NASA Research Announcement “Research Opportunities in Space and Earth Sciences (ROSES) 2016” (NNH16ZDA001N). It is currently posted on the NASA research opportunity homepage at http://nspires.nasaprs.com/ and will appear at: http://nasascience.nasa.gov/researchers/sara/grant-solicitations/roses-2016.

The NASA point of contact for this program element is Errol J. Summerlin who may be reached at errol.summerlin at nasa.gov.

4. JOB OPENING: Research Associate Opportunity at CU/NOAA SWPC
------------------------------------------------------------
From: Naomi Maruyama (naomi.maruyama at noaa.gov)

University of Colorado Boulder, Cooperative Institute for Research in Environmental Sciences (CIRES) is seeking a full-time Research Associate to work with the Space Weather Prediction Center (SWPC), part of the U.S. Department of Commerce's National Oceanic and Atmospheric Administration (NOAA), located in Boulder, Colorado. Our mission at SWPC is to deliver a real operational coupled Whole Atmosphere Model - Ionosphere-Plasmasphere-Electrodynamics (WAM-IPE) model and products in the near future. This job encompasses the development, maintenance, and management of the Ionosphere Plasmasphere Electrodynamic (IPE) model and its coupling to WAM on the NOAA/NCEP supercomputers. For more information, visit http://cires.colorado.edu/node/5817. For questions, e-mail naomi.maruyama at noaa.gov. University of Colorado is committed to diversity in hiring, and members of under-represented groups are encouraged to apply.
