SOHO SPWG Minutes




December 4, 1998 SPWG Meeting Minutes

Chair/Notes: L. Roberts (SOC) Attendees: A. Fludra (CDS), J. Charra (GOLF), S. Suess (UVCS), I. Scholl (IAS/MEDOC), A. Gabriel (IAS/GOLF), P. Bochesler (UMD, UBE, CELIAS), R. Bush (MDI/Stanford), K. Wilhelm (SUMER/MPAE), H. Benefield (FOT), N. Piston (FOT), L. Sanchez (ESA), B. Fleck (ESA), J. Gurman (NASA)

0. Announcements

* On January 15, Paal Brekke will join the ESA Project Scientist Team.

1. Review of action items

- None Open

2. SOHO Re-Certification Board Conclusions and Recommendations

- The Board acknowledges the outstanding achievements of the SOHO Recovery Team. - The spacecraft is operating in a sun pointing mode with all instruments on and collecting high quality science data. - Roll gyro redundancy has been lost, which increases the risk associated with recovery from future spacecraft anomalies. - The Board endorses implementation of several measures to increase ground system effectiveness in order to reduce risk to operations. - Recommendations include a strengthened management structure and processes with increased staffing and includes a phased approach to transition to normal operations. - Implementation of the response to the recommendations will contribute significantly to the mitigation of risk of future operations and ensure the obligations of both agencies. For the time being, the spacecraft will remain under control of the ESA Recovery Manager. There will be a new SOHO Program Office, staffed by a NASA Program Manager and an ESA Program Manager. Instrument teams should see no difference with the exception of making changes to TSTOL procedures. The requests will be submitted to a configuration control board (CCB). Instrumenter requests shall be submitted to SOCs who will forward them to the CCB.

3. Preview of future months / Boundary conditions for the coming month

- DSN on XMAS & New Year. Reminder, shortened DSN contacts on these days -- enough to dump SSR and MDI magnetograms only. - MDI Continuous: * 03:25 January 14th - 22:10 January 19th MDI OCD Deadline is 5 January at noon local time. * 3-month continuous starts on February 28th still TBD which month is best-effort depending upon WIND maneuver in April. - 6 hours SVM reserved TR Maintenance & ACU Memory Dumps, Still to be confirmed if we can move the date to Sunday 31 January 1999; rather than Monday 1 February 1999. - Upcoming Maneuvers: * 21 December, MM & SK (130 grams) * 28 January 1999, MM & SK - MEDOC Campaign in January Since a maneuver falls during the MEDOC campaign, SUMER will switch-on earlier (January 7) to perform a SUMER only 80 hour study (Sun as a Star). MEDOC campaign start date will remain on 11 January and will end when instruments close doors for the maneuver. First weekly meeting for MEDOC campaign will be on Thursday, January 7. They will have weekly meetings on Thursdays so that teams at the EOF can create IAPs on Thursday afternoons per usual. The observations scheduled by J.C. Vial have been placed into the monthly calendar. Since the monthly calendar is not currently mirrored to the ESTEC site -- the monthly calendar is appended to these minutes.

4. Priorities for the coming month

   a) Individual instrument plans
   ------------------------------
   TRACE -- continues its "eclipse season" for all of December and January,
        during which the orbit contains sunsets and orbital nights up to ~25
        minutes long.  Our observations will be limited to occasional full disk
        mosaic images or perhaps part-time flare watching on promising active
        regions.....  In the last 2 weeks, mosaic observations have been fairly
        successful, though a variety of nuisances caused by the sunrises & sunsets
        have prevented us from getting a nice time series of mosaics of any length so 
far.

        TRACE will not take part in joint observing again until eclipse season
        ends and normal operations resume in mid-February.  If there is an SPWG
        meeting in January to discuss February operations, a TRACE
        representative will be there to take an active part in the planning. 
        Proposals for JOP participation for 1999 are welcome and may be sent to
        any member of the TRACE core team; tarbell@lmsal.com and
        schryver@lmsal.com are good contacts.

   MDI -- Priority given to active region targets in the MDI high resolution 
          field of view.  Will devote first 24 hours of continuous contact to
          support of JOP022 with SUMER during the MEDOC Campaign.

   EIT -- Will do a bake-out prior to the MEDOC campaign but not exactly sure
          when they will do this.  Synoptic and CME watch continue. 

   LASCO -- Synoptic and C1 testing continues.

   SUMER -- Programs outlined in MEDOC campaign.  Second week of MEDOC campaign
            seems suited to SUMER detector A programs.  

   CDS --  Plan on a Christmas/New Year Long Duration Study: Probably a wave study 
           repeated over many days, but other long-term raster sequences being considered.
           Expect to finish on or about January 4th.  Leader: Andrzej Fludra (RAL)

	   During MEDOC campaign, Week of January 18 (probably the 20th for 2-3 days):
           CDS Real Time velocity event study, monitoring and selecting pointing in real time
           from MEDOC. Leader: Dave Pike (RAL) and Helen Mason (Cambridge)

   UVCS -- Still trying to find a planner for the last week of the MEDOC campaign.  
           UVCS would like the CDS plans for NEAR support by Thursday, December 10 -- 
           so that they can determine how to shift their synoptic program if necessary.

 
  b) Intercalibration activities
  -------------------------------
      - ICAL01 ideally would like to run the third week of the MEDOC campaign
        when Udo Schuehle is planner.  However, since the third week of the
        MEDOC campaign was shortened due to the maneuver -- it is uncertain if
        Udo will be planner that week.  Action is now on the SUMER team to 
        suggest a date to run ICAL001.

  c) Joint observing plans
  ------------------------
        - Submode Schedule:  Submode 6 until January 7.  January 7 at ~ 16:00 UT,
          switch to submode 5 for SUMER turn-on.  Probably switch back to submode
          6 after SUMER door closure for maneuvers on January 28 (will be sorted
          out after maneuver timeline is created).

5. JOPs status

- Completion of Campaign Catalog

6. New JOPs


   - New JOPs submitted for MEDOC campaign.

	* JOP095
	
	  Proposal for a Joint SOHO-GBO Campaign to Study Chromospheric
	  and TR Oscillations from Peter Heinzel and Werner Curdt
          Internal SOHO test run during the MEDOC campaign and run the 
	  full JOP in the middle of the year with Canary Island GBOs.
	  Accepted by SPWG.

	* JOP096

	  TITLE: Magnetic flux emergence in active regions
	  CONTRIBUTORS: C.E. Alissandrakis, H. Dara, C. Gontikakis, 
		      G. Tsiropoula, T. Zachariadis, J.-C. Vial
		     (+CDS, SUMER, MDI, EIT teams) 

	  INSTRUMENTS: CDS, SUMER, MDI, EIT
	  GROUND-BASED OBSERVATIONS: We will try to have Ha, microwaves

	  This JOP was approved by the SPWG with the following suggestions:
          - SUMER eliminate the OVI 1037A line and add NeVIII.
          - EIT requests a suggested cadence for the 8x8 arcmin images
            from the JOP authors. 

7. AOB

- Next SPWG on January 22 in EAF.
