SOHO SPWG Minutes



SPWG FINAL MINUTES
Friday 18 November 2005

1. Boundary conditions


- SOHO is right side up until the next manoeuvre, scheduled for 15
  December. Note: this is a change from last month's minutes.

- Graphical DSN schedule: http://soho.nascom.nasa.gov/soc/dsn/

- All available keyhole information (including December keyhole plan) is
  available from http://soho.nascom.nasa.gov/soc/keyholes.html

- We've been warned that the March keyhole is likely to be very tight,
  with very few 70m stations - close to the minimum to get MDI, GOLF
  and VIRGO continuous - very little for everyone else.

- 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.

- MDI continuous contacts are listed in Section 2 a) below and on the
  SOHO calendar.

- 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
* Dec 3-20      26m Keyhole (Dec 6-17 34m Keyhole), SM5 or SM6(end)
* Dec 6         Submode change to Submode 5, 20UT
* 2006:
* Jan 18,25     EIT Shutterless #22, 14:00-16:40 UT, SM6
* Feb 18-27     JOP175 Extended Filaments at the Limb (see sect. 2a), SM6
* Feb 22-Mar 21 26m Keyhole (Feb 28-16 34m Keyhole), SM5/6
* Mar 29-Apr 10 SUMER mini-campaign, SM5
* Mar 29        Solar Eclipse, 08:34-11:48 UT, SM5
* Apr 12,19     EIT Shutterless #23, 18:00-20:40 UT, SM6 
* May 27-Jun 14 26m Keyhole (May 31-Jun 11 34m Keyhole), SM5/6
* Jul 26,Aug 2  EIT Shutterless #24, SM6, TBC
* Aug 21-Sep 19 26m Keyhole (Aug 28-Sep 13 34m Keyhole), SM5/6
* Oct 18,25     EIT Shutterless #25, SM6, TBC
* Nov 1-Dec 15  SUMER Campaign, SM5, TBC
* Nov 24-Dec 11 26m Keyhole (Nov 27-Dec 08 34m Keyhole), SM5/6

  Some of the 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.

  SUMER will run a mini-campaign from March 29-April 10 instead of a full 
  MEDOC campaign in May/June. Chris StCyr doesn't need to run JOP175 in 
  March so there is not a conflict with that. SOC removed the Mar 17-30 
  JOP175 from the calendar.

  SUMER is further investigating a suggestion to observe during EIT
  shutterless. The spectra would be stored on-board and could be
  dumped later on. Earliest date: April 2006. More details will
  follow.

- EIT Bakeout/Other

* Dec 2-18      EIT Bakeout

  Dec 2, 2005 DSS-24 17:00-23:10 UT    begin bake 20:00 UT
  Dec 18, 2005 DSS-63/66 08:45-12:25   end bakeout 10:00 UT from plan
  Dec 18, 2005 DSS-24 16:15-22:55      21:00 UT observations resume

  EIT requests that TRACE take full disk mosaics from Dec 3 - 18. The start
  may be delayed based on the launches. TRACE will run 1700 full disk 
  mosaics daily starting November 19 and will add an EUV FDM when EIT
  bakeout begins.

- TRACE Eclipse period

* Oct 14-Feb 17 TRACE Hard Eclipse Season

  TRACE loads plans only 3 days a week (Mondays, Wednesdays, Fridays).

2. Priorities for the coming month & more



a) Joint observing plans and campaigns

Continuing campaigns:

* 2002/02/25--  JOP136 Default RHESSI Collaborations (#6850), POC:Stein Haugan
* 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 (#8005)

  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  CME watch in submode 5/6,
  except JOP175 getting half/full-res 304  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.

  JOP175 will be listed as a top-priority TOO for February 18-27. It will
  not be run March 17-30. UVCS will participate.

* Nov 28-Dec 11 Ulysses Quadrature, UVCS/Ulysses, POC: Giannina Poletto

  CDS has not received any request, but will consider advantages of
  joint observations.

  UVCS observations will start on Nov.28 and end on Dec.11. SOC changed the 
  dates accordingly.

* Dec 3-20      26m Keyhole (Dec 6-17 34m Keyhole)

* Jan 5-7       MDI Continuous Contact

* Jan 18,25     EIT Shutterless #22, 14-16:40 UT, EIT/CDS/TRACE/MDI(TBC)

  NOTE: There is a chance segment 2 will be moved to coincide with
  the (tentatively) scheduled MOSES/EUNIS launches on January 27.

  As long as it does not conflict with an MDI 3-5 Day CC period, MDI
  will support Shutterless #22 with the best observing sequence for
  the target.

  CDS is supporting, sequence is TBD.

* Jan 19,24     JOP184 Bright Points from Photosphere to Corona, CDS/Sac Peak, 
                  POC: Gerry Doyle (jgd@arm.ac.uk), TBC

* Jan 27 (TBC)  Sounding Rocket Launch, MOSES/CDS/EIT/MDI/TRACE, POC: Charles
                  Kankelborg (kankel@solar.physics.montana.edu), 18 UT
* Jan 27 (TBC)  Sounding Rocket Launch, EUNIS/EIT/CDS/TRACE/VLA,
                  POC: Jeffrey.W.Brosius.1@gsfc.nasa.gov, 18:30 UT

  NOTE: Latest news (November 28) on the launch is tenatively January
  27, 2006 (unofficial until after a White Sands scheduling meeting on
  December 14).  There is interest to couple it with the EIT shutterless
  #22, segment 2, originally scheduled for January 25, There is a
  chance this will be moved to accommodate the launches. 

  TRACE will provide their eclipse times in the hopes that the flights 
  can be timed to maximize TRACE support.

  If high rate is available, MDI will support both flights with Full
  Disk, 1 minute cadence Magnetograms and Dopplergrams along with our
  standard 96 minute synoptic, Full Disk Magnetograms and Continuum
  images.

  CDS plans are being developed.

  EIT's (non-shutterless) plan is to use FFFres synoptic sets at the
  following timings for the rocket supports:

  17:30 UT        full-field, full-res (fffr) 171  image
  17:36 UT        fffr 284  image
  17:43 UT        fffr 195  image
  17:49 UT        fffr 304  image

  18:00 UT        fffr 171  image
  18:06 UT        fffr 284  image
  18:13 UT        fffr 195  image
  18:19 UT        fffr 304  image

  18:30 UT        fffr 171  image
  18:36 UT        fffr 284  image
  18:43 UT        fffr 195  image
  18:49 UT        fffr 304  image

* Feb 1-5       MDI Continuous Contact

* Feb 18-27     JOP175 (#7135), Priority TOO, EIT/LASCO/TRACE/UVCS

  Note overlap with keyhole, below.

* Feb 22-Mar 21 26m Keyhole (Feb 28-16 34m Keyhole)

* Mar 22-May 21 MDI 60-day Continuous Contact

  We now have the current plans for the 3-5 day continuous contact periods for
  2006 on the calendar (January and February periods included in these
  minutes). Gaps between Canberra and Madrid will be requested covered by New
  Norcia.

  MDI will switch back to best focus for Full Disk observing
  before the 60 Day CC starts in March. 

* Mar 29-Apr 10 SUMER mini-campaign

  The SUMER mini-campaign will run through April 10 and there will not
  be a MEDOC campaign in May/June.

* Mar 29        Solar Eclipse, 08:34-11:48 UT, SUMER/UVCS/TRACE/CDS(TBC),
                  POC: Alan Gabriel (gabriel@ias.fr)
* Mar 29        Solar Eclipse, 10:40 UT, EIT/TRACE/LASCO, 
                  POC: Serge Koutchmy (koutchmy@iap.fr)

  SUMER has been requested to support ground based observations during
  this eclipse, so we will be in submode 5 around this date - from
  March 22-April 10. The observations will be along the lines of
  JOP002, but suggestions about a roll have been withdrawn, so an
  updated (actually, new!) JOP description should be drawn up. For
  eclipse details, see:
  http://sunearth.gsfc.nasa.gov/eclipse/SEmono/TSE2006/TSE2006.html

  CDS support for Alan Gabriel's request is under consideration.

  UVCS will participate for Mar. 27-31. 

  Serge Koutchmy sent an email on 16 November with requested
  observations from TRACE, EIT, LASCO for the eclipse: One 304 image
  at 10:40 UT +/- 2 min, and one 195 image as close as possible to
  that, either before or after. Routine images taken hours before and
  after will also be useful. LASCO images (near-simultaneous, within
  +/- 10 min, and hours before/after) are also needed.

  TRACE has received several eclipse requests and their plans are TBD.

b) Intercalibration activities

  Last Intercal 1: November 3

* Nov 23        ICAL01 (#7113), 15 UT, CDS/EIT, TBC

* Week 51/01    ICAL01 (#7113), CDS/EIT

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 70m antenna
  availability at the time.

  All requests for MDI support need to be made several months ahead of
  time and sent to mdi-ops@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 currently in better focus for high resolution observing and
  we plan on doing as much high resolution observing as possible until
  ~Jan/Feb 2006. If anyone has HR requests, send email to
  mdi-ops@mdisas.nascom.nasa.gov.

UVCS:

  We plan to use the LyA detector for special observations in the
  future when appropriate.

  For weekly plans, see the SOHO calendar and the UVCS planning page:
  http://cfa-www.harvard.edu/uvcs/observations/obst.html

  The following are listed because of NRT requirements or as candidates
  for collaboration (with e.g. CDS):

* Nov 23-24     UVCS Observations of Del Sco
* Dec 6,17      UVCS Helium Focusing Cone Observations
* Dec 18-31     UVCS Streamer Study

CDS:

  See their request diary for details:
    http://solar.bnsc.rl.ac.uk/scientificops/request.shtml

  A re-calibration of GIS (filament and raw data dumps) is under
  consideration.


LASCO/EIT:

  EIT Dec 2005 keyhole bakeout periods:
  Dec 2, 2005 DSS-24 17:00-23:10 UT    begin bake 20:00 UT
  Dec 18, 2005 DSS-63/66 08:45-12:25   end bakeout 10:00 UT from plan
  Dec 18, 2005 DSS-24 16:15-22:55      21:00 UT observations resume

  LASCO plans to get a C3-SNR calibration using the Triplets procedure
  prior to the scheduled date of the S/C transponder swap/submode 5
  change of December 6 (? 20:00 UT).  The actual time and day of this
  cal set still TBD (? Dec 3-6).  During the keyhole period C2 and C3
  will be in 'improved cadence' synoptic program, including daily
  orange/blue fielding images. The dates for this will be changed if
  the bakeout is delayed due to launches.

SUMER:

  SUMER will be observing again in the spring. A request for eclipse
  observations (March 29) has been received.

  SUMER will run a mini-campaign from March 29-April 10 and there will
  not be a MEDOC campaign in May/June.


TRACE:

  The outcome of the Senior Review of all Sun-Solar System missions this
  fall will determine the level of support (or no support) for each
  mission in the future. TRACE operations will continue through at least
  the rest of the year.

  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.

  The TRACE eclipse season is expected to end February 17. TRACE will load
  plans 3 times a week (Mondays, Wednesdays, Fridays).

3. AOB


* Next SPWG:

F Dec 16	SPWG after Daily/Weekly Meetings

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.
