--------------------------------------------- Report on the Dec. 5, 1993 GEM Mini-Workshops --------------------------------------------- GEM WORKING GROUP 1: RECONNECTION ELECTRIC FIELD AND MAGNETOPAUSE BOUNDARY NORMAL MAGNETIC FIELD L. Lyons and O. de la Beaujardiere (Co-chairs) Attention focused on results from GEM campaign periods. Considerable progress has been made with convection and boundary data from the Jan. 27-29, 1992 campaign, as discussed by Lu, Papitashvili, Lyons, and Baker. In addition, results on plasma convection associated with IMF By fluctuations on Aug. 2-3, 1991 were discussed by Clauer. Data from an Eiscat/DMSP conjunction on March 29, 1992 were discussed by Denig, and low-latitude boundary layer disturbances near 1400 MLT on this day were considered by de la Beaujardiere. AMIE and TIGCM results for March 29 have also been obtained by Lu. The important problem of identifying the magnetic separatrix on the dayside from ground-based radar data was addressed by Baker and de la Beaujardiere. Campaigns planned for 1994 are: Jan. 11, 09 UT to Jan. 14, 20 UT July 5, 09 UT to July 6, 20 UT Dec. 6, 09 UT, to Dec. 7, 20 UT
