SOHO SPWG Minutes




SPWG Minutes Wednesday May 22, 2002

1. Review of action items

Offpoint requirements are in and the offpoint has been approved by the Program Office for August 20, 2002.

2. Boundary conditions

* Next maneuver is scheduled for June 3. Fuel estimate for station keeping is roughly 0.75 kg, MM burn ~1 hour, SK burn ~101 minutes. * MDI is in continuous contact until June 2/3. * TDRS may impact our Canberra supports starting June 6. * VAULT (JOP148) will be June 14 with June 17 as a backup date. * Submodes: Submode 5 until May 31 then switch to Submode 6. Note that if a Major Flare Alert occurs in Submode 5, and SUMER is not doing Major Flare Watch-relevant observations, submode switches may be negotiated. * SUMER will close doors on Friday 31 May. * Commanding outlook: See AOB section. * EIT CalRoc and CELIAS/SEM launches shooting for a joint launch date in early August (on the 7th +/- 7 days). * Offpoint on August 20.

3. Priorities for the coming month (W23-26, June 3-30)

a) Joint observing plans and campaigns * April 25 on JOP159 CME's in Lyman-alpha (#6870), SWAN/LASCO/EIT, POC: Chris St Cyr, Eric Quemerais All teams approved the JOP. * May 23-26 JOP157 Bright Points in Active Regions (#6866), CDS/MDI/EIT/RHESSI/TRACE/GBO's, POC: Brigitte Schmieder All teams approved the JOP. TRACE was not given specific observing details for this JOP. MDI will only support this JOP on Thursday and Friday 23 and 24 May. * May 27-Jun 2 JOP158 The Fast Solar Wind from 1.05 to 4 Ro. (#6871), UVCS/CDS/SUMER/EIT/LASCO, POC: Ester Antonucci, Alan Gabriel All teams approved the JOP. LASCO will close doors on Friday 31 May and will not be able to support the JOP after that. MDI not requested for this JOP. * Jun 14 or 17 JOP148 VAULT sub-arcsecond imaging of the solar atmosphere, VAULT/TRACE/BBSO/KPNO/MDI/EIT, ~20:00 UT, POC: Gareth Lawrence (GSFC), Angelos Vourlidas (NRL) MDI may be able to support this with high resolution magnetograms, else full disk magnetograms. * Jun 11-17 JOP146 Fine Temperature and Density Structure of Coronal Loops in a Bipolar Active Region, EIT/CDS/TRACE, POC: Jonathan Cirtain * Jun 21-Jul 5 DOT/THEMIS/TRACE/SOHO Observations (TBC) TRACE coordination wanted, nothing special from SOHO. * Jul 20-26 JOP150 Dynamics and Seismology of the Solar Atmosphere, MDI/THEMIS/TRACE, POC: Alexander Kosovichev (sasha@quake.Stanford.EDU) * Jul 24 EIT Shutterless (TBC), EIT/CDS * Aug 7 EIT CalRock and CELIAS/SEM underflight (+/- 7 days) * August 20 SOHO offpoint * Sep 6-13 JOP155 Polar Coronal Jets at the Declining Phase of the Solar Cycle (TBC), UVCS/EIT/LASCO/CDS(v)/TRACE, POC: Danuta Dobrzycka Note: Support from instruments (e.g. TRACE) must be requested for this run separately. Targets of opportunity for the whole period: * JOP136/MMOP009 Default RHESSI collaboration (#6850) * JOP153/MMOP003 Major Flare Alert 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. * See also the Monthly Calendar at: http://sohowww.nascom.nasa.gov/soc/head_calendar.html b) Individual instrument plans UVCS * Jun 4 UVCS Star Observations (Tau Tau) * Jun 13-15 UVCS Star Observations (Zeta Tau) * Jun 29-Jul 1 UVCS HESSI Campaign Floating Days Note: This activity will be moved to whenever a Major Flare Watch occurs See also SOHO monthly calendar for weekly plans CDS JOP146 Temperature and Density Structure of Coronal Loops, June 11-17,2002 JOP136 - Default RHESSI Collaboration (MMOP009), TOO Usual weekly studies ICAL Future requests: JOP155 in September, EIT shutterless, EIT calrock, SOHO offpoint, MEDOC #10 See their request diary for details (http://solg2.bnsc.rl.ac.uk/scientificops/request.shtml) MDI: Next continuous contact is June 19-24 TRACE: Quadrant selector is doing better - they are moving it more. LASCO/EIT: Bakeout sometime in June * Jul 24 EIT Shutterless (TBC), EIT/CDS * Jul 30/31 EIT Shutterless Backup Day (TBC), EIT/CDS c) Intercalibration activities Last Intercal 1: May 9, 2002 * Week 24/25 ICAL01, CDS/EIT, POC: CDS Planner

4. AOB

* Next SPWG: Friday 28 June at 2pm in EAF * 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 23 - June 3-9: Monday, Thursday, Saturday, Sunday are good. Tuesday has D27 all day, Wednesday and Friday have a gap around lunchtime but good stations otherwise. Week 24 - June 10-16: Monday, Tuesday, Sunday have D27 and then a good station after that. Wednesday, Thursday, Friday are good. Saturday has a gap in the morning then a good station. Week 25 - June 17-23: Monday, Tuesday, Sunday have D27 then a good station. Wednesday, Friday, Saturday are good. Thursday has D27 all day. Week 26 - June 24-30: Monday has D27 then a good station. Tuesday, Saturday, Sunday are good. Wednesday, Friday have a gap in the morning then good staions. Thursday has D27 all day.
