SPWG, FRIDAY 20 DECEMBER 1996 10:00 AM, EAF CONFERENCE ROOM Chair: Piet Martens Minutes: Robert Doney Present: Joe Covington (MDI), Joe Gurman and Jeff Newmark (EIT), Chris StCyr (LASCO), John Raymond and Joe Michels (UVCS), Udo Schuehle, Philippe Lemaire, and Tom Moran (SUMER), Andrzej Fludra (CDS), Art Poland and Vicente Domingo (Project Scientists) AGENDA: 1 Review of action items - All items closed 2 Boundary conditions for the coming month - MDI Continuous: 1/15 6:50 UT - 1/18 21:50 UT - S/C orbit trim, station keeping, and momentum management: 1/14 - Memory dump 01 Feb 97 - No TR maintenance - Preliminary outlook on March Roll Maneuvers: Roll Maneuver: approximately 36 hours not including: Gyro Calibrations, Momentum Management, and a possible Station Keeping MDI has requested special program for March roll, requiring 22.5 degree steps and dwell after each. SWAN wants to use roll for cross-calibration - MDI also requests orbit trim and station keeping just prior to 3 months continous, i.e. in the first half of April, so that continuous program will be interrupted once at most for maneuver. Relative timing of trim, roll, and momentum management tbd (FOT, SOC's and experiments) 3 Priorities for the coming month: a) Individual instrument plans CDS: JOP018, Will run a new synoptic study (4 x 2" slit size) which will permit an additional 3 hours of viewing each day by sacrificing some resolution. Coronal Hole Jets to be run with EIT (no date yet). JOP021 shifted to week 4, and possible run in week 2. SUMER: JOP022, JOP058 have priority. Other JOPs as listed in calendar. SUMER and UVCS plan collaboration in January, details of which tbd. (More news in Jan.). UVCS: High Altitude/Coronal Hole Study [Mg(X) at approx 3 Solar Radii] LASCO: Performing Submode 2 transition at the end of this week. This is a c1-c3 cycle with 195 Angstrom EIT exposures, as well as a CME watch (FeX or FeIVX). LASCO will also try to coordinate a Galileo radio occultation study around 14 January (there is some uncertainty here since Galileo's high gain antenna failed to operate some time ago). Submode5 transition can not be performed before Jan. 20. EIT: Will perform a CCD Bakeout during week 1 or 2. There will also be JOP022 participation, and the last part of January is dedicated to Microjet studies. MDI: HiRes Study Jan. 15-18 (will try to combine with JOP022); this depends however on what is in the FOV. Jan. 7-13 possible calibration activities b) Calibration plans - Update on Intercalibration JOPs: ICAL001 and 002 will be combined into one JOP by Udo Schuehle ICAL009 on hold indefinitely, will be rewritten by Joe Michels - Schedule for intercalibration activities ICAL001 tentatively scheduled for week 4. c) Joint plans SOC thanks instrument teams for putting together a good program for January in very little time. Also, instrument planner and SOL positions are all filled for the month. For detailed January coordinated observing program see: http://sohowww.nascom.nasa.gov/operations/schedule/calendar.html 4 JOPs status - Status of Campaign Catalog, Webform for JOP-leaders' reports: The Campaign database has been redesigned to accept updated information from EOFers. An email message will be sent out to external JOP leaders with a request to complete the information on their past campaigns within the next 2 weeks. Webform will contain information on how to make such modifications. SOC's will screen inputs to eliminate hoaxes. 5 New JOPs - JOP058; No comments 6 AOB - SOHO-Yohkoh workshop, March 3-7, 1997 Subject: Sept. 25 - Oct. 5 Eruptive Event Observations Representatives: LASCO: Russ Howard & Chris St. Cyr SUMER: Jean-Claude Vial (to be confirmed) CDS: Richard Harrison & Andrzej Fludra EIT: TBD UVCS: John Kohl MDI: Craig DeForest Because of the workshop, the 36 hour Roll Maneuver should not take place during the week of MAR 3-8 * For the ISTP Meeting Jan 7-9 (BLDG 26, rm 205), SoHO instrument teams should try to get real collaborations with other ISTP missions * End of January ISTP workshop in Yosemite. ISTP wants to start producing video there, with results from ISTP missions. * MDI would like to permanently implement the reduction of VC2 time from 10 minutes to 5 minutes at the beginning of NRT during the passes. This is the proposed format: LONG CONTACT SHORT CONTACT ------------ ------------- AOS AOS VC2 (5 minutes) VC2 (5 minutes) VC4 VC4 1 hour VC2 EOS EOS * Upcoming Meetings: - JAN 17: Next SWT - JAN 24: Next SPWG * Meeting Adjourned: 11:00 am.
