Good WIND IMF data: Greenwald: N. hemisphere SuperDARN Rodger: S. hemisphere SuperDARN (Halley) R. Nakamua: GEOTAIL data 2. ISTP 18-19 Oct. 95 magnetic cloud event. Lu: AMIE results, and WIND, GEOTAIL, IMP8 data Greenwald: N. hemisphere SuperDARN data Rodger: S. hemisphere SuperDARN (Halley) MacDougal: 3-station polar-cap digital ionosonde R. Nakamura: GEOTAIL data 3. Any interesting SuperDARN data for the following dates? 11-14 Jan. 94 (1 radar pair, plus Goose and Halley; polar-cap digital ionosonde) 5-6 July 94 (1 radar pair, plus Goose and Halley) 5-7 Dec. 94 (2-pairs plus Halley; Halley data excellent on 6 Dec.; polar-cap digital ionosonde) 28 Feb.- 2 Mar. 95 (2-pairs plus Finland and Halley) WIND tail crossings on 20 Aug., 17 Sept. (Greenland B interesting), 29 Nov. (Greenland B interesting). ----------------------------------------------------------------- Monday 1:30-3:00 PROJECT D: Continuation of 3 above if necessary. PROJECT A: Identify separatrix and 2-dimensional flow versus time across and in vicinity of separatrix. 1. Pinnock/Rodger: Further HF radar studies of dayside reconnection, including reliability analyses 21 July 1992: Excellent Goose and Halley Bay data; well-defined IMF changes. Analysis of simultaneous data from both hemispheres in progress; Relation to AMIE. Multi-event study of small-scale structure in reconnection rates 2. Blanchard: Determination of dayside reconnection rates from incoherent-scatter radar data. Update on technique under development ----------------------------------------------------------------- Monday 3:30-5:00 PROJECT B: Continued studies of Aug. 2-4, 1991 period 1. Ridley: Convection reversal boundaries. Different types of boundaries (shear, rotational, traveling waves) related to solar wind parameters. PROJECT C: Pinnock/Rodger/Mende: Identify and test separatrix identification techniques with dayside optical observations, DMSP, and radars. Any interesting data or results? Dates: 6-7 Jan. 1992; 14 Jan. 1994, 6-7 Dec. 1994 PROJECT E: Polar cap convection and relations to other features 1. Lyons/Lu: "Synoptic Space Weather Maps" for Jan. 12-13, 1989 very stable IMF almost in x-direction. Initial results 2. Lu: Consideration of future periods for "Synoptic Space Weather Maps" (July 20-21, 1992; Oct. 18-19, 1995) PROJECT F: Spence: Polar high-altitude data from cusps/dayside boundary layers ----------------------------------------------------------------- Tuesday 3:30-4:15 Summary Session: What have we done and what do we want to pursue for Snowmass 1997? +-------------------------------------------------------------------------+ |To add name to the mailing list, send a message to: editor at igpp.ucla.edu | |For message to whole GEM mailing list, send to: gem at igpp.ucla.edu | | | |URL of GEM Home Page: http://igpp.ucla.edu/gem/Welcome.html | |Please update your e-mail address. | |CAUTION: Do not send messages to gem at igpp.ucla.edu unless you want | | your message to go to everyone in the GEM mailing list! | +-------------------------------------------------------------------------+
