1. Boundary conditions

- SOHO is up-side down until next manoeuvre.

- Graphical DSN schedule:

- All available keyhole information is available from 

  NOTE: Several changes have occurred since the original plan.

- 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

- 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 17-30     JOP175 Extended Filaments at the Limb (see sect. 2a), SM6
* Mar 23-Apr 4  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 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.

  SUMER plans a compact campaign starting Mar 23 and ending Apr 4.
  Ending date could be as early as Mar 31, weekend is contingency.
  Needs confirmation by IAS.

  SUMER will make a raster in the EIT FOV during the EIT shutterless
  #23, segment 1 (April 12).  Program will be loaded during the
  mini-campaign and started either by time-tag or manually (need Chris
  to press the button).  SUMER contact: Maria Madjarska

- EIT Bakeout/Other

- 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), 
                  POC: Chris St Cyr (
* 2005/09/20--  JOP153/MMOP003 Future Major Flare Watch (#8006)

  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

  JOP175 will be listed as a top-priority TOO for February 18-27 and
  March 17-30 (NOTE: the March period was first removed then added
  back in).  UVCS will participate in both periods: Feb.18-27, and
  Mar.17-26. Note that we will be in submode 5 starting approximately
  March 23 for the SUMER campaign. Note also that the "March keyhole"
  may interfere with the end of the first period/beginning of the
  second - TBD when the keyhole plan is developed.

* Jan 5-7       MDI Continuous Contact

  Plans are high resolution observations, probably at disk center.

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

  NOTE: Segment 2 will NOT be moved to coincide with the MOSES/EUNIS 

  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 (, TBC

  CDS is supporting.

* Jan 31 (TBC)  Sounding Rocket Launch, MOSES/CDS/EIT/MDI/TRACE, POC: Charles
                  Kankelborg (, 18 UT
* Jan 31 (TBC)  Sounding Rocket Launch, EUNIS/EIT/CDS/TRACE/VLA,
                  POC:, 18:30 UT

  NOTE: Latest news (December 15) on the launch is tenatively January
  31, 2006 (unofficial until after a White Sands scheduling meeting on
  January 18). We have requested extra DSN coverage.

  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

  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

  The plan is full disk Magnetograms/Dopplergrams (in best focus for 
  full disk mode).

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

  Note overlap with keyhole, below. Depending on the time a switch
  to submode 5 is needed, EIT support with full-res 304 CME Watch
  may be limited. 

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

* Mar 17-30     JOP175 (#7135), Priority TOO, EIT/LASCO/TRACE/UVCS

  Note overlap with keyhole, above, and that from March 23 SOHO will
  be in submode 5 due to the SUMER mini-campaign (below). The EIT
  support (in full-res 304 CME Watch, at least) will be limited by
  these factors.

  UVCS will participate March 17-26.

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

  Full disk Magnetograms/Dopplergrams.

* Mar 23-Apr 4 SUMER mini-campaign

  See also section 1 for details:

  - detector health check
  - plume observations
  - Jop 002
  - AR loops (off limb)

  SUMER contact will be Udo Schuehle/Klaus Wilhelm.

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

  SUMER has been requested to support ground based observations during
  this eclipse, so we will be in submode 5 around this date - from
  about March 23-April 4. 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:

  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.

  EIT also received a request from Jay Pasachoff for images as close
  to 11:00 UT as possible.

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

* Apr 12,19     EIT Shutterless #23, 18:00-20:40 UT

  SUMER plans to observe on April 12, with buffered observations in
  submode 6.

  CDS will participate.

  MDI has not received a request for support.  Due to the 60 Day CC,
  any support will come from MDI in the form of 1 minute cadence, full
  disk Magnetograms and Dopplergrams with 96 minute synoptic Mags and
  Continuum images.

b) Intercalibration activities

  Last Intercal 1: November 30

* Week 51/01    ICAL01 (#7113), CDS/EIT
* Week 05       ICAL01 (#7113), CDS/EIT

c) Individual instrument plans


  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 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

  MDI is currently in better focus for high resolution observing and
  we plan on doing as much high resolution observing as possible
  before switching back to best focus for full disk in January
  2006. If anyone has HR requests, send email to


  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:

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

* Dec 17        UVCS Helium Focusing Cone Observations
* Dec 18-31     UVCS Streamer Study
* Jan 01-18     UVCS Coronal Hole Study
* Jan 19-Feb 02 UVCS Streamer Study
* Feb 10-15     UVCS Suprathermal Seed Particle Population
* Feb 16-17     UVCS Observations of 38 Aqr
* Feb 18-27     UVCS Participation in JOP 175; CME watch
T Feb 28        UVCS safe for keyhole


  See their request diary for details:

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

  CDS will try to participate in the UVCS streamer study on selected 
  days Jan 19 - Feb 02.



  SUMER plans a compact campaign starting Mar 23 and ending Apr 4.
  Ending date could be as early as Mar 31, weekend is contingency.
  Needs confirmation by IAS.


  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 Jan 27        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

* 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.
