FINAL MINUTES FOR SOHO 24 Aug 2007 SPWG MEETING
1. Boundary conditions
a) Orbit, attitude and manoeuvres - SOHO is in upside down roll (180 deg) position - manoeuvres Aug 30 stationkeeping and momentum management Aug 31 roll Nov 20 roll, stationkeeping and momentum management (timing TBC) b) Communications with the spacecraft Graphical DSN schedule: http://soho.nascom.nasa.gov/soc/dsn/ * Aug 11-Sep 9 26 m keyhole * Aug 19-Sep 2 34 m keyhole * Nov 15-Dec 2 26 m keyhole * Nov 19-Nov 28 34 m keyhole * Feb 4-Mar 2 26 m keyhole * Feb 11-24 34 m keyhole - The need and approach to reduce FOT manpower requirements needed for complex operations during the keyhole remains in effect until further notice. 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) * Oct 24-29 SUMER campaign preparations (SM5, timing TBC) * Oct 30 EUNIS Sounding Rocket Launch, 18:00 UT (SM5, SUMER supports) * Nov 2-16 Polar Plume and Active Region Morphology Studies, SUMER/CDS/MDI/UVCS/EIT/VTT/HINODE/TRACE/STEREO-EUVI (SM5) * Nov 8,14 TBD EIT shutterless #29 (timing TBC) - dates will change - 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. - 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. d) Instrument maintenance activities EIT bakeout periods will be during keyholes. Dates and times are defined when the DSN schedules become available. During the Aug 2007 keyhole EIT will bakeout Aug 26-Sep 1. e) Others Hinode eclipse season 7 May - 10 Aug. TRACE winter eclipse season is 13 Sep 2007 - 13 Mar 2008
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 * 2003/05/13-- Default CDS Co-observations with TRACE (#6950) * 2005/09/20-- JOP153/MMOP003 Future Major Flare Watch (#8008) * 2007/03/20-- Default CDS/Hinode-EIS co-observations (#7200) Campaign #6850 is for "individual instrument studies" selecting an active region target [partially] influenced by the Max Millennium target selection to maximise chances of serendipitous co-observations. EIT supports all with half/full-res 195 A CME watch in submode 5/6. As long as the spacecraft 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. * Aug 3-31 JOP189 Microflares and Network Dynamics (#7240), CDS/EIT/MDI/TRACE/Hinode-EIS/Hinode-SOT/Hinode-XRT/ RHESSI/DOT/KSO, POC: Jan Rybak, Peter Gomory, Local POC: Tero Siili, Alex Young MDI supports JOP189 when we have high rate data. * MDI 60 Day continuous contact has been changed to Dec 3-Feb 3 * Oct 21-Nov 16 JOP190/HOP027 Temperature, Density and 3-D Structure of AR Loops, CDS/SUMER/MDI/Hinode-EIS/Hinode-SOT/ Hinode-XRT (TBD)/ TRACE (TBD)/STEREO/VTT/Huairou, POC: Davina Innes Note: this JOP run is associated with the SUMER campaign beginning on Nov 2. Due to ground-based observatory supports the run begins already on Oct 21. CDS will support. Since the 60-day continuous contact is moved, MDI can provide either full-disk or high-resolution mode observations. MDI can provide observations to all of the requested JOPs if we have high rate data and if the targets for each do not conflict (ie, one JOP wants high-resolution and another wants full-disk or some other pointing in high-resolution mode). MDI will not switch observing modes on timescales less than 24 h. MDI received a request for observations for a joint Hinode/MDI high-resolution campaign. However, the dates are not firm, but were tentatively planned for 01-15 Nov to avoid the SUMER/Hinode campaign. Now that the dates have changed, this may cause a problem. MDI is waiting to hear from Takashi Sekii on whether or not we will change the dates. * Oct 21-Nov 16 JOP191/HOP027 3-D Structure and Evolution of Filaments/ Prominences, CDS/SUMER/MDI/Hinode-EIS (TBD)/Hinode-SOT/ Hinode-XRT (TBD)/ TRACE (TBD)/STEREO/VTT/Huairou, POC: Davina Innes Note: this JOP run is associated with the SUMER campaign beginning on Nov 2. Due to ground-based observatory supports the run begins already on Oct 21. CDS will support. Since the 60 Day CC is moved, MDI can provide either FD or HR mode observations. See also response to JOP190 above. * Oct 21-Nov 16 JOP192/HOP027 Chromospheric Heating - Signatures of Waves and Reconnection, CDS/SUMER/MDI/Hinode-EIS (TBD)/ Hinode-SOT/Hinode-XRT (TBD)/TRACE (TBD)/STEREO POC: Davina Innes Note: this JOP run is associated with the SUMER campaign beginning on Nov 2. Due to ground-based observatory supports the run begins already on Oct 21. CDS will support. Since the 60 Day CC is moved, MDI can provide either FD or HR mode observations. See also response to JOP190 above. * Oct 24-29 SUMER campaign preparations (timing TBC) * Oct 30 EUNIS Sounding Rocket Launch, 18:00 UT, CDS/MDI/SUMER/EIT (all TBC), POC: Jeff Brosius, Douglas Rabin, Andrew Thomas CDS will support, need more details. Jeff Brosius had inquired about the possibility of MDI being in high-rate during the flight, which would require a backup DSN station. Backup DSN coverage request has been submitted to the scheduler, but availability information is not yet available. That time frame is, however, contentious due to Phoenix, Dawn and Selene. If a backup station turns out not to be available, we need to find out if SOHO will need to be in record and if that will be OK with the EUNIS people (in that case MDI will not get high rate data other than 96 minute Synoptic Magnetograms). From D. Rabin: Key timing goals are coincidence with Hinode observations and proximity (slighly before) local noon. The launch time is flexible approximately within 1700-2000 UTC to accommodate DSN availability. More detailed information on the launch time is forthcoming. Flight duration is approx. 10 min. Launch schedule solidifies in early October, but the launch may be delayed on about a week's notice. A likely backup launch date would be 2-3 days after the baseline date. * Oct 30-Nov 5 Polar Plumes, UVCS/SUMER/CDS/Hinode. POC: Giulio Del Zanna A Hinode HOP (entitled "Multi-wavelength observation of coronal hole plumes at solar minimum") has been proposed by Giulio Del Zanna asking an observing period 30 Oct - 4 Nov. MDI hasn't gotten a request for this. Maybe they don't need MDI support? Is this part of the other polar plume and AR study that will happen 2-16 Nov? The POC has been e-mailed to request clarification on the dates and the SOHO/TRACE supports desired. * Nov 2-16 Polar Plume and Active Region Morphology Studies, SUMER/CDS/MDI/UVCS/EIT/VTT/HINODE/TRACE/STEREO-EUVI Note that these dates have changed. JOP leaders are being contacted to see what they will change their dates to be. Submode change and SUMER door opening will be on Oct 26 or Oct 29, TBD. CDS will join the campaign - please add CDS Planner e-mail address to the mailing list. All Hinode and SUMER users are invited to submit requests for complementary CDS observations. Send requests to A.Fludra (at) rl.ac.uk and P.R.Young (at) rl.ac.uk. There are several JOPs associated with this campaign, some of which begin already before this time frame due to ground-based observatory supports. These are listed separately on the calendar (see above and below) and will have separate campaign numbers when the time gets closer. Werner Curdt writes that observers are requested to contact all instrument teams involved and to timely submit JOP/HOP descriptions with all the observational details approved. The responsibility for the proposed studies rests with the observers. Note, that TRACE will be in eclipse at that time, and EUV observations will be constrained. Several teams requested a POC for this entire time instead of individual JOP leaders. POC in ISAS: Enrico Landi (TBC) POC in MPS: Davina Innes SUMER planner in GSFC: Udo Schuehle MDI apparently has not gotten a formal request for this. See above comment about a possible collaboration between MDI and Hinode 1-15 Nov that may now conflict with the SUMER/Hinode studies including this Polar Plume Study. The TRACE team was not informed of this change in dates for the SUMER campaign and we have not heard any details about what will be run. I have changed the dates on our calendar, but it is still not clear what is running when. Also TRACE will likely decide on the level of support on a day to day basis. Also please be advised that we will be further into our eclipse season. * Nov 2-16 JOP193/HOP031 Coronal Holes Boundaries Evolution, CDS/SUMER/ MDI/Hinode-EIS/Hinode-SOT/Hinode-XRT/TRACE/STEREO/VTT, POC: Maria Madjarska CDS will support. Since the 60 Day CC is moved, MDI can provide either FD or HR mode observations. See also response to JOP190 above. Dates of this JOP were specified on Nov 23. That information has been e-mailed to instrument planners. TRACE had this running from 22 Oct - 2 Nov with specifics to be defined. Again this was with the original SUMER campaign timeframe. * Nov 6-17 Characterization of Fast and Slow Solar Wind Source Regions, SUMER/UVCS/Hinode-EIS, POC: Enrico Landi, Mari Paz Miralles A Hinode HOP has been proposed by Mari-Paz Miralles and Enrico Landi for an observation period Nov 6-17. The POC has been e-mailed to request clarification on the dates and the SOHO/TRACE supports desired. * Nov TBD HOP032 Magnetic Structure of Macrospicules, SUMER, POC: Gerry Doyle The POC has been e-mailed to request clarification on the dates and the SOHO/TRACE supports desired. * Nov TBD HOP003/Velocity Field in a Coronal Hole HOP003 Study #32, SUMER, POC: Suguru Kamio Re-run. The POC has been e-mailed to request clarification on the dates and the SOHO/TRACE supports desired. * Nov 8, 14 TBD EIT shutterless #29 - dates will change * Dec 2--->2008 Exceptional Ulysses Quadrature (ends May 28, 2008) * Dec 3-Feb 3 MDI 60-day Continuous Contact The default observing campaign will be Full Disk Magnetograms and Dopplergrams (p30vr_fd_m1 - 1100). We will not switch to high-rate during this time. * Dec 17-23 Ulysses-SOHO Quadrature Observations POC: Giannina Poletto b) Intercalibration activities Last Intercal 1: 10 August 2007 * Sep 10-14 ICAL01 (#7113), CDS/EIT, TBC Possible EIS collaboration. EIS and Stereo have been added to the Campaign #7113 description. Details and confirmation will be determined by the planners. EIT: ICALs are OK except (usually) during the weeks of shutterless. 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. MDI may also downlink select magnetograms in the 5 kbps telemetry if no 70 m passes are available at least every 2 days for Mag dump in the 160 kbps telemetry. All requests for MDI support need to be made several months ahead of time and sent to mdi-ops(at)mdisas.nascom.nasa.gov. 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 Focus 5 for best focus for FD observing and will stay there at least until March 2008. 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://www.cfa.harvard.edu/uvcs/observations/obst.html. CDS: For details see http://solar.bnsc.rl.ac.uk/scientificops/request.shtml. LASCO/EIT: EIT: 195 A CME watch plus synoptics at 6-hour cadence, as usual. Full-res CME watch whenever we're in submode 6. SUMER: Nov 2-16 Polar plume and active region morphology studies, SUMER/CDS/MDI/UVCS/EIT/VTT/HINODE (TBC)/TRACE/ STEREO-EUVI See details in Section 2a for list of JOPs/HOPs to be run at this time. There are tentative plans for another SUMER campaign from April 21 to May 4, 2008. TRACE: 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. For TRACE summer eclipse season see section 1e. During our fall eclipse season that starts in October, we will accept observing requests through Novemeber 1st. Any observations that are to take place after November 1st will be evaluated in October once eclipse season has started and then we will decide what makes sense for us to support. During the period of deepest eclipses (Nov. 16 - Feb. 15) of its winter eclipse season, TRACE will be operated by three command loads per week (Mondays, Wednesdays, and Fridays). TRACE will accept a limited number of JOP requests, giving preference to those that involve multiple observatories (in space and/or on the ground), provided that their targets can be specified on a schedule that is compatible with the reduced frequency in instrument command loads during the winter eclipse season).
3. Any other business
* VC3 and non-ranging handovers From MDI/Gregory: for automation (actually for ops in general), I would like to suggest that we do away with VC3 (except for non-ranging) handovers. I know that during long overnight contacts, the FOT traditionally go to VC3 while still giving periodic VC2 around ALT times (refer to the "Standard Ops Policy" OCD submitted 17 Oct 2005 for details). Status: the required modifications to automation software may be extensive at this point. Feasibility as well as resource expenditure vs. benefits are being assessed. Decisions are not expected until early Sep 2007 at the earliest. * .REL files' creation interval To aid getting prompt relativistic electron information from COSTEP with which to predict solar energetic particle (SEP) events, we are wondering if all instrument teams can support changing the creation interval for .REL files to 1 minute instead of 30 minutes? This would not affect real-time telemetry streams, only the .REL files that are currently ftp'd to you every 30 minutes. Status: based on e-mail inquiry responses, this approach seems to be too much effort to too many groups. COSTEP will investigate using their realtime data stream instead. EIT team has agreed to provide assistance in implementation and testing. * Next SPWG: Friday 28 September after daily & weekly meetings The rest are FYI items: * If anyone has projects that require high rate (i.e. 1 minute cadence and anything other than 96 minute synoptic Magnetograms) 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. * Future Mercury and Venus transits: SOC is requesting the Flight Dynamics Facility (FDF) to provide estimates and data for not only disk, but also for coronal transits. For this purpose FDF needs a criterion (radial/angular distance from Solar disk centre) to define the coronal transits. Currently FDF has been instructed to use SOHO/Sun/[Mercury,Venus] angle of (35 arcmin (from centre of Solar disk) as criterion. Instrument teams are requested to provide the SOC with information on whether a larger angle is applicable. * Hinode operational and planning information can be found from http://www.isas.jaxa.jp/home/solar/hinode_op/ * STEREO operational and planning information can be found via http://stereo-ssc.nascom.nasa.gov/, more specifically from http://stereo-ssc.nascom.nasa.gov/plans.shtml. * The SOHO JOP/ICAL database and the web pages are now the Solar JOP/ICAL database and web pages. This is due to anticipated increased contributions by and collaborations as well as intercalibrations with STEREO and Hinode. * To provide more unambiguous identification, individual instruments on board spacecraft other than SOHO will be as of this SPWG be referred to with notation SPACECRAFT-INSTRUMENT, for example Hinode-EIS. * The Project Scientist has decided that submission of the Inputs to the Activity Plan (IAPs) will change to be voluntary. The PS has informed the SOHO community of the change on 22 Feb by e-mail. * The FOT will begin testing the automation procedures on the week beginning 19 March. The passes will continue to be manned until after an operational readiness review and both agencies agree to a change in the mission management plan, both of which won't be for at least a couple of months, after we have significant experience with the automation. * New JOP vs. modified existing JOP rules-of-thumb: New JOP, if/when scientifically or qualitatively new type of a coordination is set up; modified JOP, when the investigation (the foci or targets thereof) remains essentially the same but new instruments/spacecraft/GBOs/etc are brought to bear.
