1. Boundary conditions

- SOHO is right side up until the the next manoeuvre, scheduled for 21
  December. The manoeuvre will include a momentum management, station
  keeping, and 180 degree roll. Fuel estimate was 139 g prior to ESR-24,
  but this is bound to change.

- The winter keyhole schedule is at:

- Scheduling windows for keyhole periods through 2005 are listed on the
  SOHO calendar. For estimated keyhole dates through 2007 see

- Long-term DSN outlook: Although substantial losses of normal VC0/1 are
  expected during 2005/2006 keyholes, GOLF and VIRGO (likely also MDI)
  will be continuous thanks to the recording patch. It may also be
  possible to have nearly continuous LASCO (submode 5) and CELIAS data in
  future keyholes.

- TRACE is in eclipse season, estimated to end around February 4.  Eclipse
  operations will be simple as usual, by default no new JOPS will be
  supported. Time may be set aside for engineering during eclipse season.

  On Thursday 23 December and Friday 31 December, TRACE will load plans
  through the following Tuesday.

  Starting 6 January, TRACE's normal uplink station will be in
  maintenance until mid-February. As a result, TRACE will have to send
  loads early (before 10am local time - times will vary).

- 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.

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
* 2003/05/13--  Default CDS Co-observations with TRACE (#6950)
* 2004/11/15--  JOP153/MMOP003 Future Major Flare Watch (#8001)
* 2002/04/25--  JOP159 CMEs in Lyman-alpha (#6870), SWAN/LASCO/EIT/UVCS,
                  POC: Chris St Cyr, Eric Quemerais
* Feb-Sep 2004  Quiescent AR Loop Diagnostics (#7019), CDS/TRACE/EIT/SUMER,
                  POC: Helen Mason (,
                  Local POC: CDS Planner
* 2004/02/19--  JOP175 Extended Filaments at the Limb, EIT/TRACE/LASCO/UVCS,
                  POC: Chris St Cyr (
* 2003/07/01--  Network-Internetwork Oscillations (#7033), EIT/TRACE,
                  POC: Scott McIntosh

  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.

  The running of the Quiescent AR Loops is left to the decision of the
  CDS planner.

  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

  An extension of the Quiescent AR Loop Diagnostics campaign is being
  discussed by the CDS team.

  Campaign 7033 is dormant until after the TRACE eclipse season.

  MDI will support with high resolution mag/doppler/filtergrams.  We
  have requested extra DSN coverage for this time between 14-22UT

  TRACE has been contacted, awaiting more details.

b) Intercalibration activities

  Last Intercal 1: October 14 (Week 42)

* Week 1        ICAL01, CDS/EIT, TBC

c) Individual instrument plans


  See section 1 (boundary conditions) for MDI continuous contact

  With the recording patch in place for the winter keyhole, and given
  that MDI can expect near-continuous medium-l data and some VC2
  during 70m contacts, MDI will take 3 magnetograms per day (00 UT, 08
  UT and 16 UT). The 00 UT magnetogram will be downlinked in VC1, the
  other two in VC2. The 08 UT and 16 UT magnetograms will be
  downlinked in VC2 every ~1.5-2.5 days and should be available on the
  web as usual for planning.

  All requests for MDI support need to be made several months ahead of
  time and sent to 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 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
  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


  For weekly plans, see the SOHO calendar and the UVCS planning page:

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

* Dec 31-Jan 09   Streamer Study
* Jan 10-16       Observations of Polar Coronal Holes
* Jan 17-23       Observations of Coronal Streamers Above 2.5 Solar Radii
* Jan 24-30       Observations of Polar Coronal Holes
* Jan 31-Feb 06   Streamer Study

  See their request diary for details:


* Dec 11-28     EIT Bakeout
* Feb 16,23     EIT Shutterless


  SUMER plans to resume operations from April 1 - May 3.


  TRACE is in eclipse season, estimated to end around February 4.  Eclipse
  operations will be simple as usual, by default no new JOPS will be
  supported. Time may be set aside for engineering during eclipse season.

  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.

3. AOB

* Next SPWG: Friday 28 January, right after weekly meeting in the EOF.

The rest are FYI items:

* If anyone has projects that require high-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.

* Commanding outlook:

  The end of December and early January finishes up the keyhole, so
  contact is limited. In January, the first few weeks have small gaps
  most days. Week 3 has some large gaps in the beginning, but otherwise
  the rest of the month has good contact with some small gaps every
  few days.

  As am experimental product, "visual" DSN schedules are available at or
  where (wn) is week number (01-53). For the weeks covered here:

  Each "line" shows one "day", from 00 UT until 04 UT next day, with
  BOT, station, and EOT indicated with text inside the plotted
  coverage box for each contact (upper left corner, middle, and lower
  right corner, respectively). Downlink only stations are indicated in
  red, uplink/downlink stations are indicated with both stations'
  details. "Reasonable working hours" (8am-5pm GSFC time - note that
  first day [Sunday] after DST starts/ends is not correctly annotated)
  are indicated in green, as well as default Daily SVM time (gray),
  14-15 UT.
