Friday 24 June 2005

1. Boundary conditions

- SOHO is upside down until the next keyhole, Aug 30-Sep 29.

- Scheduling windows for keyhole periods through 2005 are listed on
  the SOHO calendar. For estimated keyhole dates through 2008 see

- 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.

  MDI can only support requested observations with full disk, 1 minute
  cadence Magnetograms and Dopplergrams from June 25 through Sept 30,
  2005.  Due to the 60 day Continuous Contact (June 25-August 28), MDI
  will be unable to provide any high resolution observations during
  that time.  Due to the June 2005 and September 2005 Keyholes, MDI
  will be unable to provide most high RATE observations for any
  requested observations and the default program during the Keyholes
  will be either full disk, 1 minute cadence Magnetograms/Dopplergrams
  or full disk, 1 minute cadence Magnetograms/Continuum Images.  Send
  email to to request observations.
  Each request will be evaluated on an individual basis by the MDI/SOI

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 (
* 2005/01/24--  JOP153/MMOP003 Future Major Flare Watch (#8002)

  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

* Jun 5-25      26m Keyhole (Jun 9-20 34m Keyhole)

* Jun 23-Jul 6  Moat Flows and Magnetic Features, MDI/TRACE/Sac Peak,
                  POC: Mandy Hagenaar (

  Due to the 60-day continuous contact, MDI can only support with one-minute
  cadence, full disk Dopplergrams and magnetograms, with continuum images
  every 96 minutes.

* Jun 23-Jul 7  Active Region Tracking, SST/DOT/TRACE/MDI,
                  POC: Tom Berger (

  May be ending on July 2.

* Jun 25-Aug 28 MDI 60 Day Continuous Contact

  The plan is Full Disk Magnetograms and Dopplergrams. 

* Jul 3-14      JOP181 Fine Magnetic Structures/Coronal Heating (#7138),
                  Local POC: Ted Tarbell ( & Dawn Myers

  Due to the 60-day continuous contact, MDI can only support with one-minute
  cadence, full disk Dopplergrams and magnetograms, with continuum images
  every 96 minutes.

* Jul 4         Comet 9P/Tempel, SWAN/Deep Impact,

* Jul 07        Sounding Rocket Launch, VAULT/SUMER/CDS/EIT/TRACE/MDI, 
                  16:20 UT, POC: Enrico Landi ( and
                  Angelos Vourlidas (

  Backup launch days are on July 11 and July 14. There will be submode 
  changes to submode 5 the day before and to submode 6 the day after the 

  We have an extra downlink station for the July 7 launch date, not for
  the backup days. MDI full disk magnetograms are used for support, so
  we will not be in record while in contact.

  CDS will support. Studies TBD.

* Jul 20-26     Faraday Rotation Measurements, UVCS/Cassini/LASCO(TBC),
                  POC: Mari Paz Miralles (

  Joint observation during the 2005 Cassini solar conjunction (north
  coronal hole pass). Mari Paz will contact LASCO for collaboration.

* Jul 23-29     JOP083 Heating of Coronal Loops, CDS/TRACE/MDI,
                  POC: Jane Noglik (

  Building on the JOP83 observations from August 2004, TRACE and CDS to do
  similar observations, MDI for on disc targets only

  Full Disk Magnetograms/Dopplergrams ONLY from MDI.

* Aug 2         CELIAS SEM Calibration Rocket Flight, 
                  CELIAS/EIT/CDS, 18 UT, 
                  POC: Andrew Jones (

  We can not get a backup station for this. MDI accepts to be in
  record for about 10 minutes, but strongly suggests not to lengthen
  this period considering the impacts to the 60 day continuous contact.

* Aug 13-24     JOP157 Bright points in ARs, CDS/EIT/MDI/TRACE(TBC)/THEMIS/VTT,
                  POC:, TBC

  EIT will support with 195 CME Watch.

  Due to the 60-day continuous contact, MDI can only support with one-minute
  cadence, full disk Dopplergrams and magnetograms, with continuum images
  every 96 minutes.

  CDS support has been confirmed.

* Aug 18        EIT Shutterless #20, Segment 1, 17:00-19:40 UT
* Aug 18        Sounding Rocket Launch, MOSES/CDS/EIT/MDI/TRACE, ~17:45 UT, 
                  POC: Charles Kankelborg (, TBC

  We were unable to get a backup station for this new date. Since MDI
  has been requested to supply full disk magnetograms, the spacecraft
  will not be recording while we are in (continuous) contact.

  CDS studies are under consideration.

  The EIT Shutterless is supporting the MOSES launch.

* Aug 18-21     Spicule Study, TRACE/SST, POC:

* Aug 24        EIT Shutterless #20, Segment 2

  The shutterless run for August 31 has been moved to August 18.

  As always, supporting with at least Full Disk Magnetograms/Doppler.

* Aug 30-Sep 29 26m Keyhole (Sep 6-22 34m Keyhole)

* Sep 1-10      Wave Propagation from Photosphere to Corona, MDI/SST/DOT/TRACE,
                  POC: Bart DePontieu (

  MDI will try to collaborate as much as DSN allows (half of the period is
  within the 34m keyhole) and as long as this study doesn't conflict with
  JOP178 (they might actually have overlapping observations at certain times).
  Request for HR Mag/Doppler/Filtergrams or FD Mags/Doppler.

* Sep 7-21      JOP178 Filament and its Environment, MDI/CDS/EIT/TRACE/GBOs,
                  POC: Thierry Roudier (, TBC

  EIT supports with 195  CME Watch plus TBD 304  observations if not
  in bakeout or otherwise prevented by keyhole.

  MDI will try to collaborate as much as DSN allows (during 34m keyhole) with
  HR or FD Magnetograms.

  TRACE will join on September 11 (when Bart DePontieu's study is

* Sep 22-28     Filament Observations, CDS/EIT/THEMIS,
                  POC:, TBC

  CDS supports as the keyhole schedule allows.

  EIT participation beyond CME watch (if not in bakeout - TBD)
  dependent on contact and ground observing schedules, since it could
  involve sector wheel motions.

* Sep 23-Oct 17 Magnetic Elements and Waves in the Chromosphere,
                  MDI/TRACE/SST, POC:

  MDI: This begins during the 26-m Keyhole and overlaps with a 5-day
  continuous contact period, Oct 12-16. HR Mag/Doppler program likely for the
  continuous contact period if target in the high res FOV.

* Oct TBD       Sounding Rocket Launch, EUNIS/EIT/CDS/TRACE,
                  POC:, TBC

* Oct 6-17      Fine Scale Structures, 
                  POC: Georgia Tsiropoula (

  JOP description being worked on.

  CDS does not seem to have received a request yet.

  MDI: This occurs mostly during the 5-day CC period. The MDI program for that
  period will likely be high resolution. We should be able to give them good
  support on Oct 6-11, DSN schedule permitting, and support during the
  continuous contact, if they coordinate with with the Magnetic Elements &
  Waves program.

  Submode changes for this will be on October 5 and 18, TBC.

* Oct 12-16     MDI Continuous Contact, TBC

  MDI: High res Mag/Doppler or 3-variable high res program likely since there
  has been interest expressed by several collaborators, provided the targets
  are in the MDI high res FOV.

* Oct 18-22     JOP179 Energy Propagation in XBPs, CDS/EIT/MDI/Hida,
                  POC: Tetsuya Watanabe (

  Hida observing times are about 21 - 06 UT.

  CDS will support, but needs more details.

  MDI: The request is for FD Magnetograms & Dopplergrams at 1-min cadence,
  which we can probably provide, DSN permitting. 

  EIT support is 195  CME watch (submode 6)

* Oct 19, 26    EIT Shutterless, TBC

b) Intercalibration activities

  Last Intercal 1: April 6

* Week 26       ICAL01 (#7113), CDS/EIT
* Week 30       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


  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):

* Jun 24-30     UVCS Observations of North Polar Coronal Hole
* Jul 1-8       UVCS Observations of the South Polar Coronal Hole
* Jul 9-19      UVCS Measurements of Suprathermal Seed Particle Populations 
                  in the Extended Solar Corona
* Jul 27-31     UVCS Streamer Study

  UVCS is also contacting CDS regarding a possible collaboration on
  the CDS coronal hole observations June 27 - July 2.

  See their request diary for details:

  CDS will consider joining UVCS studies above if time allows.



  Will be observing for the VAULT launch on July 7 and then again in


  The TRACE Mission will not be terminated on 1 October. NASA has
  decided to have a Senior Review of all Sun-Solar System missions this
  fall, the outcome of which will determine the level of support (or no
  support) for each mission in the future. TRACE operations will
  therefore continue through at least the rest of the year, especially
  through the summer observing season in the northern hemisphere.

  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:

F Jul 29        SPWG Meeting, TBC

  UVCS prefers July 22. We will try to get the draft minutes out before
  then to allow a UVCS response, but no promises. Input can also be sent
  prior to the draft.

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.
