SOHO SPWG Minutes



SPWG MINUTES Friday November 22, 2002

1. Review of action items

From last meeting: * All teams: Give a list of email addresses to be added to the SPWG list (to make sure all relevant people receive the draft and final minutes) We will add: trace_planner@cheyenne mdiops@mdisas grl@kreutz planner@uvcs6 Remove: Several, by request (new duplicates and dead mailboxes) * All teams, each SPWG meeting: Designate one person to be point of contact for collaborations and to review & "sign off" on SPWG draft agendas The following list is based on inputs and *assumptions*: CDS: Andrzej Fludra CELIAS: Peter Bochsler CEPAC: Jarmo Torsti, Horst Kunow GOLF: Alan Gabriel EIT: Joe Gurman (Alex Young is backup) LASCO: Gareth Lawrence MDI: Rock Bush - Sarah Gregory is POC for collaborations SUMER: Werner Curdt SWAN: Eric Quemerais, Asko Lehto UVCS: Yuan-Kuen Ko VIRGO: Claus Frolich TRACE: Dawn Myers Replies from CELIAS, SWAN & VIRGO still pending for both of the above.

2. Boundary conditions

* The next MM/SK maneuver is tentatively scheduled for February 19, 2003. Fuel estimate for stationkeeping: 0.4xx kg. * No action for SOHO during the Leonids meteor shower (Nov 18 & 19) * TRACE is in eclipse season * 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 There may be limited contacts on New Years Day as well * MDI continuous contacts: Dec 26-27 MDI 2-day continuous contact Jan 20-Feb 16 MDI best effort continuous contact period 2003 Note: The 5-day continuous planned for December 26-31 has shrunk! * Submodes: Submode 6 except for these submode 5 periods: November 15, 17 UT - November 22, 17 UT (SOHO-Ulysses quadrature support) December 2, 19 UT - December 4, 20 UT (SUMER Eclipse support) April 7 - approximately - for one to two weeks (SUMER mini-campaign) * Commanding outlook: See AOB section. NOTE: Late additions: * The ground-observable Mercury disk transit on May 7, 2003, is expected to be visible from SOHO (details pending). * The ground-observable Venus disk transit on June 8, 2004 will miss by about 160 arcseconds as seen from SOHO, from the latest calculations.

3. Priorities for the coming month (W49-W52; December 2 - December 29)

a) Joint observing plans and campaigns * Nov 25-Dec 3 SOHO-Ulysses quadrature (PA 296.7), UVCS/Ulysses, POC: Luca Teriaca/Giannina Poletto * Nov 26-27 Extended Observations of AR Loops, CDS/EIT, POC: Jack Ireland * Dec 4 Total Solar Eclipse, EIT/LASCO/SUMER/UVCS/MLSO/GBO, See http://soho.nascom.nasa.gov/soc/dec2002_eclipse/ SUMER will command from MEDOC. Additional observing details will be put on the web pages. The SSR will be in record from 05:15 - 09:30 UT. TRACE has not received any requests for eclipse support yet - contact trace_planner@cheyenne.nascom.nasa.gov if you would like to request something. * Dec 10-12 Blinker Study, CDS/MDI/TRACE/Tenerife/La Palma, 9-16 UT, POC: Jack Ireland (local)/Hardi Peter * Apr 2003 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 may be 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. 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: November 13 (Week 46) * Dec 3-5,18 Intercal 1, CDS/EIT, POC: CDS/EIT Planners c) Individual instrument plans (See the SOHO monthly calendar for weekly plans) CDS: See their request diary for details (http://solg2.bnsc.rl.ac.uk/scientificops/request.shtml) LASCO/EIT: EIT Shutterless: January 8 (primary), January 23 (backup) 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 December 20 RIGHT AFTER WEEKLY MEETING IN THE EOF. * Instrument teams should send 1-3 lines with their tentative weekly plans 10 minutes before the daily/weekly meetings. * 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. * Commanding outlook - These times are subject to change - More details available if wanted: Week 49 - Dec 2 - Dec 8: Monday has D27 in the morning followed by a gap then a good station. Tuesday has D27 all day. Wednesday has a large gap. Thursday - Sunday are good with a tiny afternoon gap. Week 50 - Dec 9 - Dec 15: Monday - Thursday have D27 in the morning followed by a gap then a good station. Friday has a gap. Saturday and Sunday have D27 part of the day. Week 51 - Dec 16 - Dec 22: Large gaps on Tuesday, Friday, Saturday, Sunday. D27 part of Monday. Wednesday is good. D27 all day Thursday. Week 52 - Dec 23 - Dec 29: Large gaps on Monday, Tuesday, Wednesday, Saturday. D27 part of the day on Tuesday, Wednesday, Sunday. D27 all day Thursday. Friday is good. Week 01 - Dec 30 - Jan 5: Large gaps on Monday, Tuesday, Friday. D27 part of the day on Tuesday, Wednesday, Thursday, Friday. D27 all day Saturday. Sunday is good.
