DRAFT MINUTES FOR SOHO SPWG MEETING ON 20070727 Latest Update: $Date: 2007/07/26 20:48:54 $ $Author: tsiili $ $Revision: 1.8 $ Change log is at the end of the document. 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 - 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 22-Nov 2 Polar plume and active region morphology studies, SUMER/VTT/HINODE (TBC)/TRACE/STEREO * Aug 2,9 EIT shutterless #28 (timing TBC) * Nov 8,14 EIT shutterless #29 (timing TBC) - 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 as follows: 2007/08/26 DSS-24 16:05 - 01:00; bakeout begins by 21:00 UT 2007/09/01 bakeout ends from plan at 09:00 UT 2007/09/01 DSS-24 15:30 - 17:30 EIT recovery 2007/09/01 DSS-27 18:30 - 20:00 additional recovery time if needed. 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. * Jul 3-Aug 5 JOP 188 Prominence Mass Composition and Variability Study, CDS/EIT/MDI/TRACE/STEREO-EUVI/Hinode-SOT/Hinode-EIS/MLSO, POC: Gary Kilper, Local POC: Terry Kucera, Joe Gurman A study on the relative abundances of hydrogen and helium in prominences and on their trends in spatial distribution and variability over time is proposed. The method is measurement of the continuum absorption due to photoionization for EUV observations and of the absorption in H-alpha (6563 A) and He I (10830 A). EIT will support. MDI will support with synoptic Continuum Images when in high rate. Bill Thompson says: Both JOP188 and Filament/Cavity-CME-ICME IHY-CIP campaign are on the STEREO planning pages. From what I understand, the SECCHI team has been contacted, and is aware that the campaign organizers may request that the timing of the extra 4 hours of SSR2 observations be synchronized with observing time in Hawaii. Simon Plunkett says that they will not be able to make special changes until mid-July. Gary Kilper has updated the JOP description with the following changes: Observations from July 3 - August 5 Daily e-mail with targeting info will be sent by garyk@rice.edu Observing window is 16:30 to 02:42 UT (the next day) Targets: quiescent limb prominences CDS has not been contacted yet. We are assuming this is a target of opportunity to be run on several days in the indicated period. Are there plans to run this JOP continuously? TRACE will start supporting this JOP on July 9. --> #STEREO, #Hinode-SOT, #Hinode-EIS - changes, comments? * Aug 2,9 EIT Shutterless #28 Aug 2 DSS-27 15:00 - 20:45, runtime 16:00-18:40 UT Aug 9 DSS-27 18:45 - 00:45, runtime 20:00-22:40 UT * Aug 3-31 JOP 189 Physical mechanisms driving solar microflares and supergranular network dynamics - relevance for coronal heating, CDS/EIT/MDI/Hinode-EIS/Hinode-SOT/Hinode-XRT/ RHESSI/TRACE/DOT/KSO, POC: Jan Rybak, Peter Gomory, Local POC: C. Alex Young The local POC has changed from T. Siili to C. A. Young. Detailed campaign/coordination information can be found at http://www.astro.sk/~choc/open/07_dot/07_dot.html. Having in mind the SOHO keyhole we plan to request for the Hinode support mainly after Aug 17 expecting the SOHO will be supporting (at least) partially until Aug 17 in the time interval 07:00-13:30 UT (for UT times, see also the Aug 5-18 campaign). CDS will support on selected dates, as time allows. EIT will support through Aug 25 (until the beginning of the CCD bakeout). TRACE will only support 20-31 Aug. MDI will support with HR Filtergrams and Magnetograms when target in the HRFOV. FD Magnetograms and Dopplergrams otherwise. JOP targets will also be specified preferably in the HRFOV. The Hinode/EIS,SOT,XRT application has been sent on May 31. Application asks for the Hinode support for the period Aug 18-31. Negotiations are on the way discussing details with the EIS team. --> #Hinode-EIS, #Hinode-SOT, #Hinode-XRT - changes, comments? * Aug 8-18 JOP194 Activity in Filaments and Filament Cavities, CDS/UVCS/EIT/TRACE/Hinode-EIS/Hinode-XRT/Hinode-SOT/COMP/ SOLARC/ProMag/MWA/RHESSI, POC: Terry Kucera As part of the International Heliophysical Year (IHY), we propose an observing campaign in the time interval August 5-18, 2007 which will follow a targetted filament from East to West limb, in order to study its morphology, evolution and activation, and quantify its magnetic and plasma properties. Our study will be greatly enhanced should the filament erupt as a CME, and if it does, we will also examine in situ observations in order to link any pertinent ICME and magnetic cloud observations to their filament source. The campaign is a conglomeration of four International Heliophysical Year (IHY) Coordinated Investigaton Programmes (CIPs) which are headed up by Barbara Thompson, Sarah Gibson, Holly Gilbert and Pat McIntosh. The most important time of day for campaign participation would be 17:00 -- 20:00 UT, the best observing period of Mauna Loa. The full Mauna Loa observing day can run from 16:30 -- 02:30 UT. Scheduling spacecraft supports to these times would help to interleave with the JOP 189, which has its ground-based support focus on Canary islands and in Europe. EIT will support JOP194 Aug 8-18 with 304A CME Watch at 12-min cadence along with 10'x10' subfields in 304A in observation periods to improve cadence. EIT shutterless #28 Aug 9 will be included in the JOP194 support. POC Susanna Parenti . This will be made into a combination of JOPs and campaigns, exact details are still TBC. The 4 IHY Coordinated Investigation Programs (CIPs) have websites at: http://www.ukssdc.ac.uk/cgi-bin/ihy/cip-filter.pl?number=7 http://www.ukssdc.ac.uk/cgi-bin/ihy/cip-filter.pl?number=21 http://www.ukssdc.ac.uk/cgi-bin/ihy/cip-filter.pl?number=23 http://www.ukssdc.ac.uk/cgi-bin/ihy/cip-filter.pl?number=51 Bill Thompson says: Both JOP188 and Filament/Cavity-CME-ICME IHY-CIP campaign are on the STEREO planning pages. From what I understand, the SECCHI team has been contacted, and is aware that the campaign organizers may request that the timing of the extra 4 hours of SSR2 observations be synchronized with observing time in Hawaii. Simon Plunkett says that they will not be able to make special changes until mid-July. Terry Kucera says that the dates have been changed to August 8-18. She provided a JOP description, now called JOP194: http://sohowww.nascom.nasa.gov/soc/JOPs/jop194.txt For UVCS, if the target has not reached within 30 degrees to the limb, they will do 'synoptic study of the west-limb corona'. CDS will support. Still no request for MDI support. At this point JOP189 takes priority over coordinations that MDI will participate in during August. Terry Kucera says that they will not make a special request for MDI data. MDI's 96 minute ALT cadence will change during the keyhole. --> #Hinode-EIS, #Hinode-XRT, #Hinode-SOT - changes, comments? * Sep 10-Nov 11 MDI 60-day Continuous Contact (TBC) Tina Kelly has proposed to shift the 60-day continuous contact from Sep-Nov to Dec-Jan timeframe. The outcome of the proposal remains TBD. MDI will run 1 min cadence, full disk magnetograms and dopplergrams --- independent of the timing of the 60-day CC. MDI would like the DSN schedule for the 60 Day CC as soon as it is available. * Oct 22-Nov 4 Polar plume and active region morphology studies, SUMER/VTT/HINODE (TBC)/TRACE/STEREO/CDS 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. There are several JOPs associated with this campaign. These are listed separately on the calendar (see 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 Schühle --> #HINODE, #STEREO - changes, comments? * Oct 22-Nov 2 JOP190/HOP027 Temperature, density and 3-D structure of active region loops, CDS/SUMER/MDI/Hinode-EIS/Hinode-SOT/ Hinode-XRT (TBD)/ TRACE (TBD)/STEREO/VTT/Huairou, POC: Davina Innes CDS will support. MDI can only support with 1 minute full disk Magnetograms/Dopplergrams and 96 minute synoptic Magnetograms and Continuum images (when in high rate).

MDI can only support with 1 minute full disk Magnetograms/Dopplergrams and 96 minute synoptic Magnetograms and Continuum images (when in high rate). If the 60 Day CC is moved, MDI can provide either FD or HR mode observations. --> #Hinode-EIS, #Hinode-SOT, #Hinode-XRT, #STEREO - changes, comments? * Oct 22-Nov 2 HOP032 The magnetic structure of macrospicules. POC: G. Doyle * Oct 22-Nov 4 Solar wind study. POC: E.Landi, M.Miralles HOP submission in progress. * Oct 22-Nov 4 Plume study.

Poletto * Dec 26-30 MDI Continuous Contact Depends on whether or not there is a 60 day CC during this time, but the default plan will be FD, 1 minute cadence Magnetograms and Dopplergrams. b) Intercalibration activities Last Intercal 1: 11 July 2007 * August 6-10 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. --> Hinode-EIS - 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. 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 through November. 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. LASCO and EIT will do annual instrument calibrations during morning and daytime NRT week of Jul 30 - Aug 3. SUMER: Oct 22-Nov 2 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. 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). We can talk about this after the SPWG if necessary. * .REL files' creation interval To aid getting prompt relativistic electron information from COSTEP with which to predict 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: the above request for information has been sent to the teams and the SOCs are compiling the replies before the matter is taken further. MDI has requested clarification on the changes proposed to the .REL files procedure. * Next SPWG: Friday 24 August or 31 August (the day of the roll) after daily & weekly meetings CDS: No comment EIT: Either is OK MDI: Aug 24 preferred SUMER: No comment TRACE: No comment UVCS: Aug 31 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. $Log: agenda.txt,v $ Revision 1.8 2007/07/26 20:48:54 tsiili Changed JOP 189 local POC.
