SOHO SPWG Minutes



SPWG FINAL MINUTES Friday December 20, 2002

1. Review of action items

From last meeting: * All teams, each SPWG meeting: Designate one person to be point of contact for collaborations and to review & "sign off" on SPWG draft agendas. Confirmation from CELIAS (Peter Bochsler) and VIRGO (Claus Fr÷hlich) pending. They will be contacted on an as-needed basis.

2. Boundary conditions

* TRACE may have to stop science operations temporarily some time in January if the next installment of FY 2003 funding is not received from GSFC shortly after New Years. The TRACE PI team at Lockheed Martin (and Project Scientist at GSFC) have been working for many months to have GSFC extend its contract and provide the FY 2003 funding recommended by the Senior Review. The process is ongoing but still not completed. * The next MM/SK maneuver is tentatively scheduled for February 19, 2003. Fuel estimate for stationkeeping: 0.4xx kg. * TRACE is in eclipse season, end date is still uncertain * Christmas Eve and Day will have limited contacts, suggestion for the Christmas week follows: Monday and Thursday will be normal Tuesday (Christmas Eve): D66 06:55-11:35 UT, D27 18:30-23:30 UT Wednesday (Christmas Day): D66 06:55-12:00 UT, D27 19:25-23:05 UT As far as we know, New Years-related contacts will not be limited * MDI continuous contacts: Dec 26-27 MDI 2-day continuous contact Jan 20-Feb 16 MDI best effort continuous contact period 2003 (27 days) Note: The 5-day continuous planned for December is only 2 days! * EIT Bakeout tentatively scheduled for January 31 - February 3, TRACE will be taking full disk mosaics. * The Mercury disk transit on May 7, 2003 will be visible from SOHO. MDI will be doing observations during the transit, so we cannot use the SSR. We have asked for a backup (likely downlink only) station; details pending. We have also asked for a tabulation of the position vs time to be calculated after the February 19 stationkeeping maneuver. More details (copy of emails sent to the SPWG list on November 27) at http://soho.nascom.nasa.gov/soc/mercury2003/transit-email.txt * The ground-observable Venus disk transit on June 8, 2004 will be a coronal transit as seen from SOHO. * Submodes: Submode 6 except for these submode 5 periods: April 2 - 21/22 (approximately) for a SUMER mini-campaign * Commanding outlook: See AOB section.

3. Priorities for the coming month (W1-W5; December 30 - February 2)

a) Joint observing plans and campaigns W Jan 08 EIT Shutterless Run #9, 17-19:40 UT, EIT/CDS/TRACE, POC: Erwin Verwichte, Local POC: Kevin Schenk * Jan 14-18 JOP146 Fine Temperature/Density Structure of Coronal Loops in a Bipolar AR, CDS/TRACE, POC: Jonathan Cirtain T Jan 23 Backup EIT Shutterless Run #9, 14-16:40 UT, EIT/CDS/TRACE, POC: Erwin Verwichte, Local POC: Kevin Schenk * Mar 9-20 Magnetic Field Evolution around Leading Sunspots, TRACE/Sac Peak ASP/[MDI]/CDS, POC: Ted Tarbell We have indicated we would like to have a JOP written for the occasion. * Apr 7-16 JOP161 Comprehensive Footpoint Study, SUMER/CDS/EIT/MDI/TRACE, POC: Scott McIntosh CDS, EIT, TRACE, MDI agree to a test run (time TBD - early in 2003). MDI High Rate coverage has been requested for the real campaign. Some details in the JOP will be filled in, e.g: EIT & CDS observing details (EIT program will be something other than Intercal 1 program). LASCO observations may be impacted by EIT (both test and proper runs); they agree in principle, pending discussion at next telecon. MDI support for test run is not possible after January 20. The test run may be done without MDI support. Continuing campaigns: * JOP159 CME's in Lyman-alpha (#6870), SWAN/LASCO/EIT/UVCS*, POC: Chris St Cyr, Eric Quemerais Targets of opportunity for the whole period: * JOP136/MMOP009 Default RHESSI collaboration (#6850) * JOP153/MMOP003 Major Flare Alert (#6892) Campaign number 6850 has been set aside for "individual instrument studies" that select their AR target [partially] influenced by the RHESSI target. Note that the RHESSI target will be observed by a significant number of ground based observatories, so chances for serendipitous co-observations are larger when selecting the RHESSI target. b) Intercalibration activities Last Intercal 1: December 5 (Week 49) * Week 1/2 Intercal 1, CDS/EIT, POC: CDS/EIT Planners CDS prefers Tues/Wed/Thurs, any date before January 14 EIT prefers week 2. c) Individual instrument plans (See the SOHO monthly calendar for weekly plans) UVCS: * Jan 28-29 UVCS Observations of Comet Kudo-Fujikawa (C/2002 X5) MDI: * Jan 20-Feb 16 MDI best effort continuous contact period 2003 A full disk doppler and magnetic campaign will be run during this period - no other coordination is practical. JOP136/153 will be supported as much as high rate telemetry and continuous contacts allow. CDS: See their request diary for details (http://solg2.bnsc.rl.ac.uk/scientificops/request.shtml) LASCO/EIT: EIT Shutterless (304 ┼, 68s cadence): January 8 17:00-19:40 UT (primary), January 23 14:00-16:40 UT (backup) From Erwin Verwichte (erwinv@oma.be): I would like to announce this campaign to other instrument teams who may be interested to coordinate their observations w.r.t. this campaign: - TRACE: Would the TRACE team be willing to participate to this run? If so, our preference of bandpass for TRACE is 171A. - Are the CDS and SPIRIT teams interested to participate? Please let me know who will be the coordinator/planner for your instrument. Information concerning the EIT High-cadence synoptic program may be found at the ROB website http://sol.oma.be/High-cadence. EIT Bakeout tentatively scheduled for January 31 - February 3. TRACE: During TRACE eclipse season (starts Novermber 4, ends in February), TRACE will do 3 loads per week during eclipse season and stay with one wavelength for an extended period of time. No additional collaborations will be done other than those previously agreed to.

4. AOB

* Next SPWG: Friday January 24 RIGHT AFTER WEEKLY MEETING IN THE EOF * DSN support should be requested at least 6 months in advance. Keep this in mind for: ground-based collaborations that require MDI support, stellar/shutterless observations that require NRT, etc. * If anyone has projects that require high-cadence MDI support, now is a good time to ask! If you need MDI data, make sure you request it specifically. There is no significant change in the shutter performance over the last 10 months; monitoring continues, but no immediate changes in operations are planned. * Commanding outlook - These times are subject to change - More details available if wanted: Week 1 - Dec 30 - Jan 05: Afternoon gaps and lots of D27 this week. Sunday is good. Week 2 - Jan 06 - Jan 12: D27 from 15-20 UT then D46 on Monday, Saturday, and Sunday. Gap until 19 UT then D27 on Tuesday and Thursday. Wednesday is good. Friday has a gap from 15-20 UT. Week 3 - Jan 13 - Jan 19: D27 all day Wednesday, Saturday, Sunday. Gaps on Monday, Tuesday, Thursday, Friday, with D27 after those gaps on Monday and Thursday. Week 4 - Jan 20 - Jan 26: Continuous contact begins on Monday. D27 in the afternoons on Monday, Tuesday, Wednesday, Saturday. Gap then D27 on Thursday and Friday. Sunday is good. Week 5 - Jan 27 - Feb 2: No information available on this week yet.
