*************************** ** THE GEM MESSENGER ** *************************** Volume 3, Number 5 April 28, 1993 ----------------------------------- Notes from the NSF Program Director ----------------------------------- A request has been made to extend my rotational appointment up to January 15 to provide more time and continuity for the Magnetospheric Physics program. We need a highly qualified candidate for a start date as early as August 15 and no later than January 15. Potential candidates should contact Tim Eastman or Rich Behnke at 202-357-7618. Tim Eastman ---------------------------------------------- Report of 1992 Snowmass Tail/Substorm Workshop ---------------------------------------------- The report of 1992 Snowmass Tail/Substorm Workshop will be available 2-3 weeks from now. It will be mailed to everyone in the GEM mailing list in late May. If your name is not in the GEM mailing list and would like to receive a copy, please send your name and address to Jeff Hughes at e-mail address "HUGHES at buasta.bu.edu". ----------------------------------------- Report to GEM on the Second IACG Workshop ----------------------------------------- The Interagency Consultative Group (IACG) consists of the heads of the space agencies of Europe, Japan, the United States and the confederation of Independent States(ESA, NASDA, NASA and IKI). The IACG was established during the Halley encounter period to maximize the scientific return of these missions. This effort was so successful that the IACG has continued to meet annually to coordinate the scientific space program. The latest thrust of the IACG is to coordinate the spacecraft contributing to the ISTP program. To do this they are planning three "campaigns": a Magnetotail and Substorm campaign, a Boundaries in Collisionless Plasmas campaign, and a Solar campaign. The former campaign was organized in June 1992 at a workshop in Airlie House, Virginia. The results of this workshop are contained in the document "Towards a New Era of Global Solar-Terrestrial Research: The First Inter-Agency Consultative Group (IACG) Campaign: Magnetotail, Energy Flow and Non-Linear Dynamics." This report is available from E. C. Whipple of NASA (SPAN address: NHQVAX::EWHIPPLE). The second campaign was organized at a workshop held in Graz, Austria April 13-15, 1993. The third workshop to plan a campaign on Solar Disturbances will be held next year. The Graz workshop was attended by close to 60 scientists associated with the programs of the four major space agencies. I was asked to cochair the deliberations of the panel on the magnetopause. I was also asked by the GEM Steering committee to represent GEM's interests at this workshop. Herein is my interim report to the GEM community. The organizer of the Graz workshop was Rudi Schmidt of ESTEC and the editor of the final report will be Goertz Paschmann of MPE/Garching. The workshop began with invited review papers on the bow shocks (G. Zastenker and A. Nozdrachev), on the magnetopause (B. Sonnerup), on current sheets (E. Priest), particle acceleration (D. Baker), mission oriented theory (M. Abdalla), the European Plasma Simulation Network (A. Roux) and ground observations (H. Opgenoorth). The attendees then split into 4 panels: The bow shock under S. Schwartz and the M. Scholer, the magnetopause under G. Paschmann and myself, current sheets under L. Zelenyi and E. Antonucci and particle acceleration under T. Terasawa. These groups then met to decide how the available missions could be coordinated to maximize the scientific return in each of their areas. A common procedure was to identify spacecraft constellations or configurations that were ideally suited to address particular objectives. The community would then be called upon to emphasize data gathering and analysis during these intervals. The reports of each panel were then presented to Goertz Paschmann who in turn presented the draft plans to the IACG. Goertz Paschmann is now assembling the written contributions and will issue a report on the second campaign roughly following the style of the report on the first campaign. It should be apparent from the above discussion that the purview of the IACG campaign is much wider than that of the GEM campaign which is bounded by the ionosphere on the one hand and the magnetosphere on the other. For example, the current layer panel discussed current layers from the magnetotail to the Sun. Linkages between GEM and the IACG campaigns would be a useful topic for the Snowmass meeting. C. T.
