SPWG DRAFT MINUTES (last changed 28 Apr 2006 at 13:40 UTC by T. Siili) Friday 28 April 2006 1. Boundary conditions a) Orbit, attitude and manoeuvres - SOHO is currently right side up - manoeuvres Jun 6 roll, stationkeeping and momentum management Sep 5 stationkeeping and momentum management; roll date separate and TBC (timing TBC) Dec 5 roll, stationkeeping and momentum management (timing TBC) b) Communications with the spacecraft - Graphical DSN schedule: http://soho.nascom.nasa.gov/soc/dsn/ * May 27-Jun 14 26 m Keyhole Tentatively VGM-only or VGMFL5-only. For details see below. * May 31-Jun 11 34 m Keyhole Tentatively VGM-only or VGMFL5-only. For details see below. * Aug 21-Sep 19 26 m Keyhole * Aug 28-Sep 13 34 m Keyhole * Nov 24-Dec 11 26 m keyhole * Nov 27-Dec 8 26 m keyhole Note: the keyhole plan for the June keyhole will be based on VGM-only or VGMFL5-only to reduce FOT manpower requirements needed for complex operations during the keyhole. This will allow the FOT personnel to devote more time on the development of future more automated operations. The tradeoff is some less science accomplished. Similar approach is planned also for the Sep keyhole. All available keyhole information is at http://soho.nascom.nasa.gov/soc/keyholes.html c) KNOWN submode dependent activities/submode changes: * TOO JOP153/MMOP003 Future Major Flare Watch (SM5 if SUMER observes target, SM6 otherwise) * TOO JOP175 Extended Filaments at the Limb (see sect. 2a), SM6 * May 27-Jun 14 26 m Keyhole (May 31-Jun 11 34 m Keyhole), SM5/6 * Jul 26,Aug 2 EIT Shutterless #24, SM6, TBC * Aug 21-Sep 19 26 m Keyhole (Aug 28-Sep 13 34 m Keyhole), SM5/6 * Oct 18,25 EIT Shutterless #25, SM6, TBC * Nov 1-Dec 15 SUMER Campaign, SM5, TBC * Nov 8 Transit of Mercury, SM5/6 * Nov 24-Dec 11 26 m Keyhole (Nov 27-Dec 08 34 m Keyhole), SM5/6 Some of the default SUMER campaign dates overlap with keyholes - which is not a problem in itself (submode 5 will often be needed for keyholes anyhow) as long as potential periods of no SUMER data between passes can be accepted. According to EIT the Mercury transit observations can be carried out in either submode 5 or 6. FDF has been contacted to get the observational geometry. - Except for Major Flare Watches, TRACE will be doing full disk mosaics if/when EIT is not able to do synoptic sets due to keyhole operations. --> #CDS, #LASCO, #SUMER - additions, changes, comments? d) Instrument maintenance activities - EIT Bakeout --> #EIT - date(s) known yet? e) Others - TRACE eclipses TRACE is in its normal operations mode until the next 'eclipse season', which is estimated to start on 2 Oct 2006 (doy 275) and last through to 13 Apr 2007 (doy 103). --> #CDS, #LASCO, #SUMER - changes, comments? 2. Priorities for the coming month and more a) Joint observing plans and campaigns Continuing campaigns: * 2002/02/25-- JOP136 Default RHESSI Collaborations (#6850), POC: Tero Siili * 2002/04/25-- JOP159 CMEs in Lyman-alpha (#6870), SWAN/LASCO/EIT/UVCS, POC: Chris St Cyr, Eric Quemerais * 2003/05/13-- Default CDS Co-observations with TRACE (#6950) * 2003/07/01-- Network-Internetwork Oscillations (#7033), EIT/TRACE, POC: Scott McIntosh * 2004/02/19-- JOP175 Extended Filaments at the Limb (#7135), EIT/TRACE/LASCO/UVCS, POC: Chris St Cyr (Chris.StCyr@nasa.gov) * 2005/09/20-- JOP153/MMOP003 Future Major Flare Watch (#8006) Campaign #6850 is for "individual instrument studies" selecting an AR target [partially] influenced by the Max Millennium target selection to maximise chances of serendipitous co-observations. EIT supports all with half/full-res 195 Å CME watch in submode 5/6, except JOP175 getting half/full-res 304 Å CME watch in submode 5/6, and Network-Internetwork Oscillations which is TBD by Scott McIntosh. As long as the S/C is in submode 6, all EIT CME watch will be in full res. Major Flare Watches will be in full-res even if it requires a submode change, unless the target is observed by SUMER. The question of whether or not to continue campaign #7033 (Network- Internetwork Oscillations) has been brought up, and the issue of how to list a possible "final, long run" has been raised. If that run will involve a significant change to the existing campaign, e.g. by including Solar-B instruments, it should be a separate item (and the current campaign can be closed). If not, the campaign can be continued until the final run has been done, to keep things simple by using the existing campaign number. The INO study has been removed from the TRACE calendar until an explicit request is made --> #CDS, #LASCO, #SUMER - changes, comments? * Mar 22-May 21 MDI 60-day Continuous Contact Full disk Magnetograms/Dopplergrams. New Norcia will cover a few of the gaps (see below). For additional details, see the graphical DSN schedule. 16 Apr 2006 (DOY 106) 05:25-06:05 UT 30 Apr 2006 (DOY 120) 01:35-04:00 UT 12 May 2006 (DOY 132) 00:15-00:40 UT 20 May 2006 (DOY 140) 00:20-01:40 UT * Jun 3-9 La Palma Observations, Facular irradiance characteristics Sunspot penumbral filament and/or light-bridge dynamics, MDI/TRACE/La Palma, POC: Tom Berger, TBC Obervation time 08-18 UTC. MDI will try to support this run, but due to the keyhole support will be limited. TRACE will support this observation and a program has been defined. * Jun 12-18 Ulysses-SOHO quadrature observations UVCS team is looking into the possibility of starting the quadrature observations earlier than Jun 12. Since part of this campaign is during the June keyhole, as much data coverage as possible for UVCS is preferred. * Jun 28-Jul 12 JOP171 Solar Network Variability and Dynamics, CDS/EIT/MDI/TRACE/DOT, POC: Peter Gomory CDS has worked out the details with Peter already. EIT sees no problems supporting the request. MDI will likely support the request, tentatively taking 1-min cadence high-res magnetograms, dopplergrams and filtergrams. TRACE will support this observation and a program has been defined. --> #CDS - changes, comments? * Jul 12-16 MDI Continuous Contact The default plan is high resolution magnetograms, dopplergrams and filtergrams, but it's subject to change based on solar activity and general requests for MDI observations. We may continue with whatever we run for JOP171. * Jul 26, Aug 2 EIT Shutterless #24, TBC * Jul 22 STEREO launch (TBC) * Aug 16-20 MDI Continuous Contact The default plan is high-resolution magnetograms and dopplergrams. * Aug 25-Sep 3 JOP178/JOP157 Filament and its Environment, MDI/CDS/EIT/TRACE/THEMIS/GBOs, POC: Brigitte Schmieder,TBC Overlaps with the September keyhole. MDI will try to support this for the first couple of days, but after that, no support is guaranteed. --> #CDS - changes, comments? * Sep 27-Oct 6 La Palma observations, Propagation of low frequency waves & spicule formation, MDI/TRACE/SSO, POC: Bart DePontieu MDI has requested extra DSN coverage for 08-18 UTC. Default plan is high resolution magnetograms, dopplergrams and filtergrams (or some combination of the three). TRACE is supporting this request (TBC). * Oct 11-15 MDI Continuous Contact No plans yet, default plan is full-disk magnetograms and dopplergrams. * Oct 24 Dual sounding rocket launch for CELIAS/SEM, TIMED/SEE and SDO/EVE cross-calibration, TRACE, POC: Andrew Jones, TBC Exact launch time is TBD, but most likely it will be 1720-2020 UTC. This is an expanded repeat of 2005 Aug CELIAS/SEM calibration flight. Backup launch date is between 7-27 Feb 2007. Request is for going to record for approximately 10 min even if SOHO is in contact. MDI is OK with going to record for 10 min. TRACE would like to participate and has contacted the POC. --> #CELIAS - further info, changes, comments? * Oct 18,25 EIT Shutterless #25, TBC * Oct 25-Nov 2 La Palma observations, Facular irradiance characteristics Sunspot penumbral filament and/or light-bridge dynamics, MDI/TRACE/SSO, POC: Tom Berger MDI has requested extra DSN coverage for 08-18 UTC. Default plan is high resolution magnetograms, dopplergrams and filtergrams (or some combination of the three). TRACE supports this request. b) Intercalibration activities Last Intercal 1: 5 Apr 2006, 27 Apr 2006 - Week 21 ICAL01 (#7113), CDS/EIT, TBC Details and confirmation will be determined by the planners. --> #CDS - changes, comments? c) Individual instrument plans MDI: See section 2a for MDI continuous contact periods. MDI may reduce the ALT cadence during Keyholes to be less than 15 ALT magnetograms per day if the lack of high rate telemetry is such that we will lose all or almost all of the 15 ALT Magnetograms each day. The ALT cadence will be decided on an individual Keyhole basis and even a daily basis during each Keyhole depending on the 70 m antenna availability at the time. All requests for MDI support need to be made several months ahead of time and sent to email@example.com. Even outside keyholes, MDI can only do 1-minute cadence observations when we have contact and there is no recorder dump in progress. MDI's REQUEST page is at http://mdisas.nascom.nasa.gov/coordination.txt NOTE: Listing of a study on that page means *only* that a request has been received, not that it will necessarily be supported. A description of MDI Observing Modes most used for JOPs and campaigns (FD vs. HR) can be found at http://mdisas.nascom.nasa.gov/Collaborate. Anyone requesting MDI observations is encouraged to read this page in order to have a better idea of what observing modes would be best suited for a particular study. More detailed information about how MDI operates, observational constraints and telemetry information can be found at http://mdisas.nascom.nasa.gov/MDI_Collaboration_Details. MDI is back in best focus for Full Disk observing and may switch to better high-resolution observation focus after the June keyhole, in preparation for late summer/early fall timeframe requests for high-res observations. UVCS: We have been using the LyA detector for some observations and will keep planning so when appropriate. For weekly plans, see the SOHO calendar and the UVCS planning page: http://cfa-www.harvard.edu/uvcs/observations/obst.html CDS: See their request diary for details: http://solar.bnsc.rl.ac.uk/scientificops/request.shtml --> #CDS - changes, comments? LASCO/EIT: --> #LASCO - changes, comments? SUMER: --> #SUMER - changes, comments? TRACE: TRACE is in its normal operations mode until the next 'eclipse season' (for estimated dates see section 1e). NASA has announced that it plans to continue funding of TRACE operations at close to the FY06 level through FY08, followed by a significant ramping down of operations into FY09. NOTE that TRACE in general reserves the right to withdraw support from agreed, existing collaborations if a sufficiently "good active region" is called by the Max Millennium group. 3. AOB * Next SPWG: Fri May 26 after the Daily/Weekly Meetings. --> #CDS, #LASCO, #SUMER - other suggestions? The rest are FYI items: * If anyone has projects that require high rate (i.e. 1 minute 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. * 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. * Solar-B launch is currently scheduled for 23 Sep 2006. Science observations (including some MDI, TRACE and possibly STEREO collaborations) are tentatively scheduled to begin approximately 45 d thereafter. Spacecraft and launch site scheduling issues may push the launch from Sep to Nov-Dec time frame. * STEREO launch is currently scheduled for 22 Jul 2006.
