DRAFT MINUTES FOR SOHO SPWG MEETING ON 20090424 Latest Update: $Date: 2009/04/24 13:53:24 $ $Author: tsiili $ $Revision: 1.10 $ Change log is at the end of the document. 1. Boundary conditions a) Orbit, attitude and manoeuvres - SOHO is right side up (0 degrees). - manoeuvres To the degree possible, manoeuvres take place during the last days of 34-m keyholes. Currently proposed or set manoeuvre dates are: May 12 (TBC) station-keeping, momentum management, roll (to approximately 180 degrees) Aug 11 (TBC) station-keeping and momentum management Aug 13 (TBC) roll (to approximately 0 degrees) b) Communications with the spacecraft Graphical DSN schedule: http://soho.nascom.nasa.gov/soc/dsn/ Keyhole dates for the next 6 months (All keyhole information is available at or via http://soho.nascom.nasa.gov/soc/keyholes.html): * Apr 28-May 16 26m Keyhole * May 02-12 34m Keyhole * Jul 22-Aug 20 26m Keyhole * Jul 29-Aug 13 34m Keyhole * Jul 22-Aug 20 26m Keyhole * Jul 29-Aug 13 34m Keyhole - End-of-pass handling during MDI continuous contact periods To avoid problems with transmitter masks at the end of passes during MDI continuous, DSN has requested we bring the carrier down 30 min before the end of pass. As a result, the last 30 min of all MDI continuous contacts will be TM only. For ranging passes, the spacecraft will be transitioned to record ~1 h before the end of the pass. The station will drop the carrier and re-sweep into receiver 2. The spacecraft will then be transitioned back to VC2 and VC3. - DSN 26 m antenna decommissioning and the keyholes DSN is in the process of decommissioning its 26 m antennae --- the only one left is DSS-46. DSS-46 is planned to be decommissioned Oct 31, 2009. DSS-46 may, however, be decommissioned as early as Aug 3, 2009. Since the current high-gain antenna (HGA) position along the unmoved axis has been optimized for 26 m antennas, the spacecraft team is investigating moving the HGA to a position optimized for 34 m antennae. Such a change would shorten or remove the keyholes, but DSN resource allocation issues and possible impacts on MDI and MDI/SDO-HMI cross-calibration period need to be addressed. For analyses and details see the minutes of Science Working Team meeting number 40 (available at http://sohowww.nascom.nasa.gov/operations/SWT/Minutes/swt40.pdf, pages 38--41). c) KNOWN submode (SM) dependent activities/submode changes: * TOO JOP153/MMOP003 Future Major Flare Watch (SM5 if SUMER observes target, SM6 otherwise) * Apr 15-29 SUMER campaign (SM5) * Jun 1-Jul 10 Sunrise 5-day balloon flight * Jun 25, Jul 2 EIT shutterless #36 (time TBC) * Oct 8, 15 EIT shutterless #37 (time TBC) * Jan 7, 15 EIT shutterless #38 (time TBC) SUMER campaign dates may overlap with keyholes. Such overlaps shall be scheduled only if periods of no SUMER data between passes are acceptable. SUMER campaign ending activities related to the Apr 15-29 campaign are proposed to be scheduled as follows: Door closing late on Apr 30. Submode change 5->6 on May 12 prior to LASCO recovery from maneuver safing on May 12. SUMER will observe during the Sunrise balloon flight. Note, that the balloon launch is scheduled for Jun 1 - Jul 5 and the duration is expected to be 5 days. For submode change plan see the Sunrise entry in section 2a below. 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 * May 2-8 EIT bakeout e) Spacecraft maintenance activities Reduction of PLM heaters was successfully completed. Jean-Philippe Olive is in the process of contacting all teams about the instruments' heaters. This relates to future optimization of thermal control and electric power supply. Since the FOT staffing (and hence the FOT's resources to implement changes quickly) will decrease towards the end of this calendar year, all instrument teams are reminded to review not only thermal, but also other limits as well as TSTOL procedures and scripts for possible changes. --> #ALL: changes, comments? f) Others TRACE eclipse season began on 13 Sep 2008 and will be ongoing, except for the following predicted non-eclipse periods in 2009: Mar 7 -- Apr 29 Jul 28 -- Sep 9 TRACE will not perform science operations from May 15 - July 12, and from September 30 through early December. Daytime weekday passes of Mon-Wed are currently automated but attended. Thu-Fri passes remain crewed for training and proficiency reasons. Date of transition to unattended daytime automation remains TBD. NRT during automated passes (both weekend and weekday) is currently paused (briefly) regularly for resets of software anomalies. NRT schedule (which includes the pauses) for all automated passes can be found at http://sohowww.nascom.nasa.gov/soc/nighttime_nrt.txt. The development of a software anomaly detection system (which would pause NRT only when needed instead of the current regular pauses) has been put on hold due to problems in development. 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. It is clear that STEREO-EUVI provides adequate "context" information for RHESSI flare observations. Routine EIT submode and resolution switches are probably no longer needed. --> #CDS, #STEREO-EUVI: changes, comments? * Mar 16 - Sep LASCO C2pB for Tomography Reconstruction, POC: Angelos Vourlidas, Richard Frazin * Mar 27- JOP 222 (ToO) Detecting the Origin of Shock-Accelerated Solar Energetic Particles, LASCO/STEREO-SECCHI POC: Angelos Vourlidas --> #STEREO-SECCHI: changes, comments? * Apr 15-29 SUMER-Hinode Campaign, POC: Davina Innes NOTE: the campaign will be to a large degree over, when this SPWG meeting is held. The definitive sources of information are - the campaign planning web site (password-protected, contact campaign POC or the SOHO SOCs for access): http://www.mps.mpg.de/services/campaignplanner/planning/campaign-200904/index.cgi?print=no (Click on schedule - observer) - SOHO calendar: http://sohowww.nascom.nasa.gov/soc/head_calendar.html - SOHO campaign database: http://sohodata.nascom.nasa.gov/cgi-bin/soho_campaign_search A lookup table between different observation/collaboration identifiers is given below: CmpID JOP HOP CmpNR 1 219 86 7308 2 Not used 3 210 110 7310 4 Not used 5 Not used 6 214 73 7302 7 215 7301 8 178 111 7313 9 221 112 7316 10 Not used 11 80 7300 12 105 7306 13 SUMER-only 14 SUMER-only 15 SUMER-only 16 207 82 7314 17 207 82 7314 18 108 7309 19 217 106 7312 20 218 7304 21 108 7309 22 220 109 7305 23 223 107 7303 24 104 7315 25 7307 CmpID = SUMER-Hinode website campaign identifier CmpNR = SOHO campaign number All participants are requested to check the planning web site given above and to complete missing ops details (if any). For information on SUMER preparatory and campaign ending activities see section 1c above. TRACE has not received any requests from JOP 214 & awaits date and program information. CDS requests to be added to the mailing list to receive information (including pointing coordinates) for all JOPs. MDI will support all requested observations as best we can, not changing HR pointing, observing sequence or observing mode on timescales less than 24 h. Only JOPs with other than date and time information are listed below. For other JOPs, see the campaign web site or the SOHO calendar. * Apr 17, 20 JOP 218 Dynamics and structure of the solar atmosphere from SUMER and VTT observations (SUMER-Hinode campaign program ID 20), MDI/SUMER/TRACE/VTT POC: L. Teriaca MDI will support with HR Magnetograms if the target is within the MDI high resolution (HR) field of view (HRFOV). * Apr 18-26 JOP 219 Connection between photospheric vortex flows and transition region and coronal heating (SUMER-Hinode campaign program ID 1), MDI/SUMER/Hinode-EIS/Hinode-SOT/Hinode-XRT/TRACE(TBD)/ STEREO(TBD) POC: Davina Innes Currently scheduled to run on Apr 18, 22, 26. Requested DSN coverage for Apr 18 obtained, Apr 22 and 26 remain TBD. For details see the campaign web site. MDI will support with HR Magnetograms as requested if the target is within the MDI HRFOV. * Apr 18-28 JOP 215 Connection between the magnetic canopy and chromospheric/lower transition region dynamics, SUMER/MDI/VTT, (SUMER-Hinode campaign program ID 7), POC: Anna Pietarila, Currently scheduled to run on Apr 18-19 and 21-28. For details see the campaign web site. HR observations specifically, hr_ve_fe_me, is requested from MDI. However, the JOP description indicates the MDI data is for coalignment, so would MDI synoptic HR images would be sufficient? Will coordinate with JOP POC, but MDI may be in HR mode anyway for another SUMER/Hinode JOP. POC reply/comment on MDI: Any MDI HR data (also synoptic) support for JOP 215 would be wonderful. POC reply/comment on SUMER and timing: Part of the SUMER observing sequences reserved for JOP215 will be most likely be used by Werner Curdt for Ly-alpha studies. Exact dates have not yet been decided. * Apr 23-29 JOP 178 Filament and its environment (footpoints and filament channel) CDS/EIT/MDI/TRACE (all TBC) (SUMER-Hinode campaign program ID 8), POC: Brigitte Schmieder Currently scheduled to run on Apr 23-25 and 28-29. For details see the campaign web site. MDI has not gotten a formal request to support this, but as long as it does not conflict with JOP's 219/218/215 then MDI can support JOP178. If MDI is running in HR mode, though, on any given day for another JOP and JOP178 wants us to switch to FD, we will not do so on timescales less than 24 hours. TRACE has also not gotten a request to support this JOP. EIT will support with 304 A CME watch binned 512x512 at the synoptic 12 min cadence. * Apr 23-28 JOP 207/HOP 82 Eruptive and quiescent prominences Atlas with SOHO and Hinode CDS/SUMER/UVCS/Hinode-EIS/Hinode-SOT/Hinode-XRT (SUMER-Hinode campaign program ID 16 & 17), POC: Susanna Parenti The two different campaign program IDs refer to two different pointings. Currently scheduled to run on Apr 23-24 and 27-28. For details see the campaign web site. * May 15-Jul 12 TRACE not performing science operations * May 17-Jul 21 MDI 60-day continuous contact Timing TBC. The continuous contact period will be a 60-day period within the dates listed above. MDI will run p30vr_fd_c1, a full disk, 1 minute cadence Velocity and Continuum campaign during the 60 day CC along with the usual 96 minute Full Disk synoptic Magnetograms and Continuum. The only possible change to this observing sequence will be to change to p30vr_fd_m1, a full disk, 1 minute cadence Velocity and Magnetogram campaign to support the 5 day Sunrise balloon flight. * Jun 1-Jul 10 Sunrise 5-day balloon flight, MDI/SUMER/TRACE, POC: Davina Innes In June or July 2009 a balloon borne solar observatory called 'Sunrise' is planned to be launched and SoHO (at least MDI and SUMER) as well as TRACE supports have been requested. The launch date will be sometime between Jun 1 and Jul 5, 2009 and the flight lasts 5 days. Coordinated observations with SoHO would therefore be for five days sometime between 1 June to 10 July 2009. NOTE: TRACE has announced, that no science operations will be conducted from May 15 - July 12 (see also section 2c and http://chippewa.nascom.nasa.gov/TRACE/ops/timeline/monthly_plan/current_plan.txt). A short description of SUNRISE is given in http://star.mpae.gwdg.de/Sunrise/project/publicat/SPIE_2004.pdf A tentative timeline of the flight is below: Major milestones (x = moment of tether cutting): x - 3 weeks: Hardware arrives at lauch facilty x - 3 days : Launch readiness review x - 3 days : SUMER opens aperture door (remotely) x -24 hours: Next day launch announcement x + 1 hour : Launch confirmed x + 6 hours: Ascent completed x + 6 hours: Switch-on sequence and initial tests x +12 hours: SUNRISE operational x +12 hours: SOHO submode switch x + 5 days : Science operations completed Submode change 6 -> 5 is proposed to take place during the next working shift after SUNRISE is launched. CDS concurs, as long as the submode change timing allows for CDS crash recovery (if needed) and loading on one single pass. MDI can support with full-disk, 1-min cadence magnetograms and dopplergrams if there is high rate at the time. MDI support will be the ONLY interruption to the 60 day CC plans of running a Full Disk Velocity and Continuum campaign. See above notes for the 60 day CC period. SOHO will NOT go to record at any point for this flight since it will occur during the 60 day Continuous Contact period. * June (TBC) HERSCHEL sounding rocket launch, CDS/EIT/LASCO/UVCS/STEREO/TRACE POC: Dan Moses, Lucia Abbo HERSCHEL has successfully passed all per-launch testing, but due to issues with availability of critical project personnel, the launch has been postponed to June 2009, exact date remaining TBC. The rocket payload consists of a suite of 3 instruments: SCORE/Ultraviolet Coronagraph Imager (UVCI), Herschel EIT (HEIT) and Helium Coronagraph (HeCor). The HERSCHEL Sun-Earth Sub-Orbital Program is a sounding-rocket payload designed to investigate Helium coronal abundance and solar wind acceleration from a range of solar source structures by obtaining simultaneous observations of the electron, proton and Helium Solar coronae. HERSCHEL will provide the first measurements of the coronal He abundance in source regions of the solar wind, thus bringing key elements to our understanding of the Sun-Earth connections. Timing and supporting SOHO instruments remain TBC. The HERSCHEL team is currently involved in integration and test activities. The critical milestones thereof are expected to be completed by the beginning of March. The official request on the launch date will not be made until then. EIT is OK with SOHO being in submode 5. Support will be a four-filter synoptic set binned over the rocket flight timing. LASCO support will be C2 pB set orange filter binned before and after the flight time around the EIT filter set. CDS will participate, taking on-disk He I and 2nd order He II observations. Request to add CDS planner to the mailing list. TRACE hopes to support HERSCHEL sounding rocket launch, but support depends on the scheduled downtime. See also section 2b (intercalibration activities) for proposed SOHO/STEREO/TRACE/HERSCHEL cross-calibration. --> #CDS, #UVCS, #STEREO: changes, comments? * Jun 25 (TBC) EIT shutterless #36 run 1 Hopefully no conflict between Sunrise and SUMER 5-day observations. * Jul 2 (TBC) EIT shutterless #36 run 2 Hopefully no conflict between Sunrise and SUMER 5-day observations. * Jul 22 Total Solar eclipse (around 0236 UT) Information on the eclipse itself can be found at URL http://eclipse.gsfc.nasa.gov/SEpubs/20090722/TP214169a.pdf. The key numbers can be found also at http://eclipse.gsfc.nasa.gov/SEmono/TSE2009/TSE2009iau/TSE2009-fig01.GIF. The external/internal contacts of Umbra occur at: U1 = 00:51:14.3 UT U2 = 00:54:28.4 UT U3 = 04:16:10.5 UT U4 = 04:19:23.9 UT Tentative DSN schedule for the eclipse date and the preceding date is as follows: Jul 21 D45 2315-0215 Jul 22 D65 0720-1120 Jul 22 D27 1830-2230 (uplink) Jul 22 D15 1830-2230 (downlink) The week has not been negotiated and there is no guarantee that the passes remain as is. Unless the DSN supports change, SOHO will not be able to be in contact during the eclipse. SOCs will attempt to obtain DSN support better covering the eclipse. Jay Pasachoff's expedition will observe from the vicinity of Hangzhou, China. Mid-eclipse time will be at 01:36 UT. The team would like to have a full set of EIT and LASCO images, one of each type, as close as possible to that time and repeating as often as possible +/- 3 min from mid-eclipse, if it is possible to get more than one image during our totality (which is probably not possible). EIT/LASCO: no support requests yet, but will participate. --> #ALL: supports? * Jul 28 (TBC) SUMI sounding rocket launch, CDS/MDI/TRACE, TBC POC: Jonathan Cirtain (TBC) NOTE: launch postponed from Apr 16 to Jul 28. The new date is approcimately a week into the Aug 2009 keyhole, which very likely would restrict MDI and SUMER supports. The SUMI POCs have been notified and urged to move the launch to a better date, but no reply has been received yet. MDI needs to know what observations (full-disk or high resolution) are needed for the SUMI rocket launch. This is during the Jul/Aug 2009 SOHO Keyhole, so MDI high rate (ie, 1 minute cadence images and some 96 minute synoptic Mags) will be limited. TRACE has been asked to support this rocket launch. --> #CDS: changes, comments? * Sep 30-Dec TBD TRACE not performing science operations * Oct 8 (TBC) EIT shutterless #37 run 1 * Oct 15 (TBC) EIT shutterless #37 run 2 * Jan 7 (TBC) EIT shutterless #38 run 1 * Jan 15 (TBC) EIT shutterless #38 run 2 b) Intercalibration activities Last ICAL was: Mar 09 ICALs are normally performed monthly. Below is a SOC proposal for ICAL weeks for the next six months. Baseline will be to schedule it for Thursday during contact. * Apr 6-10 ICAL01 (#7113), CDS/EIT/STEREO/Hinode-EIS(TBD)/Hinode-SOT(TBD) * May 11-22 ICAL01 (#7113), CDS/EIT/STEREO/Hinode-EIS(TBD)/Hinode-SOT(TBD) * June (TBC) ICAL14 SOHO-STEREO-TRACE-HERSCHEL radiometric cross-calibration (TBC), EIT/LASCO/UVCS/STEREO/TRACE/HERSCHEL, POC: Lucia Abbo A radiometric cross-calibration between SOHO, STEREO, TRACE and the HERSCHEL sounding rocket has been proposed. A preliminary draft of the ICAL proposal can be found at http://sohowww.nascom.nasa.gov/soc/JOPs/ical014-draft.pdf. TRACE hopes to support HERSCHEL sounding rocket launch, but support depends on the scheduled downtime. * Jun 15-19 ICAL01 (#7113), CDS/EIT/STEREO/Hinode-EIS(TBD)/Hinode-SOT(TBD) The Sunrise balloon flight period may need to be taken into account in scheduling. * Jul 13-17 ICAL01 (#7113), CDS/EIT/STEREO/Hinode-EIS(TBD)/Hinode-SOT(TBD) * Aug 17-21 ICAL01 (#7113), CDS/EIT/STEREO/Hinode-EIS(TBD)/Hinode-SOT(TBD) NOTE: the Aug 2009 keyhole ends on 20 Aug 2009, hence this run should be possible during the proposed time, but may also be postponed to the following week. * Sep 14-18 ICAL01 (#7113), CDS/EIT/STEREO/Hinode-EIS(TBD)/Hinode-SOT(TBD) * Oct 12-16 ICAL01 (#7113), CDS/EIT/STEREO/Hinode-EIS(TBD)/Hinode-SOT(TBD) Proposed compiled ICAL scheduling criteria, constraints and guidelines (see also campaign #7113): 1) EIT/CDS are the primary participating instruments 2) STEREO-EUVI observations are included when possible. ICALs are attempted to be scheduled not to coincide with STEREO manoeuvres or other interruptions in observations (see http://stereo-ssc.nascom.nasa.gov/plans.shtml). 3) EIT: ICALs OK at all other times except the weeks of shutterless 4) Dates, details and confirmation will be determined by the planners with support from the SOHO SOCs. 5) Neither Hinode-SOT nor Hinode-XRT have current interest in participating in ICALs. Hinode-EIS will from time-to-time perform its sensitivity calibration exercise, but has no need to perform this regularly as part of the SOHO ICAL. When it is convenient for Hinode-EIS (given Hinode's constraints), SOHO will be informed ahead of time of when the sensitivity calibration is to be performed. It will then be up to SOHO whether to follow Hinode-EIS' pointing and timing. CDS OK. If Hinode-EIS can suggest convenient date & time, CDS can usually accommodate. --> #CDS, #STEREO, #Hinode-EIS, #Hinode-SOT: changes, comments? --> #UVCS: changes, comments (esp. on ICAL14)? 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 down-link 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 has switched to Focus 5 (best focus for full-disk observing) on Oct 23, 2008. MDI will do Full Disk Velocity observations for March and September 2009. These FD Velocity observations are reserved specifically to collaborate with Hinode-SOT. MDI also reserves the March (28-30) continuous contact for FD Helioseimology studies with Hinode-SOT. UVCS: For weekly plans, see the SOHO calendar and the UVCS planning page: http://www.cfa.harvard.edu/uvcs/observations/obst.html. --> #UVCS: changes, comments? CDS: For details see http://solar.bnsc.rl.ac.uk/scientificops/request.shtml. --> #CDS: changes, comments? EIT/LASCO: EIT: 195 A CME watch plus synoptics at 6-hour cadence, as usual. Full-res CME watch whenever we're in submode 6. Hope never to change until the Bogart mission. EIT JOP178 April 23-29 support: 304A cme watch half res, synoptics May 11 17:00 UT Lasco safes for maneuvers/roll. May 12 20:00 UT LASCO recovers and observes (opening before CDS to allow limited interuption to C2pB Topography). CDS plans to recover May 14, LASCO will close doors for the hour around CDS recovery time due to debris. SUMER: See section 2a for details. SUMER has plans for another campaign after SDO commissioning. Dates are still TBD. 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 1f. TRACE will not perform science operations from May 15 - July 12, and from September 30 through early December. See also http://chippewa.nascom.nasa.gov/TRACE/ops/timeline/monthly_plan/current_plan.txt. 3. Any other business * Tentative SPWG meeting times for next six months (only the next one will be decided in this meeting). Meetings take place as a baseline on Fridays after the daily and weekly meetings. Apr 24 May 29 Jun 26 Jul 24 Aug 21 Sep 25 Oct 30 The rest are FYI items: * In the future SOHO's DSN contacts will grow shorter as we lose 26-m antenna support and other, new missions get higher priority. The instrument teams are therefore requested to look at the NRT commanding that is done (especially for emergencies and recoveries) and see what can be converted into TSTOLs that the FOT can run (even without explicit instrument or SOC direction). * MDI high-rate support requests: no change, see URL http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html * DSN support requests: preferably 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: no change, see URL http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html * Hinode operational and planning information and guidelines: no change, see URL http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html and http://sohowww.nascom.nasa.gov/soc/JOPs/jop-submit.html * STEREO operational and planning information: no change, see URL http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html * 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. * New JOP vs. modified existing JOP rules-of-thumb: no change, see URL http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html * SOHO calendar email notifications: no change, see URL http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html $Log: agenda.txt,v $ Revision 1.10 2009/04/24 13:53:24 tsiili Updated the SUMER-Hinode lookup table.
