Friday 20 May 2005

1. Boundary conditions

- SOHO is right side up until the next manoeuvre, scheduled for June
  17. Fuel estimate is about 0.041 kg.

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

- The June preliminary(*) keyhole schedule can be found at

  The keyhole plan in graphical format can be found at

  (*) NOTE: There will be changes to this schedule due to late-
  breaking DSN changes.

- 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.

  NOTE that the back-to-back-to-back summer keyhole, 60-day
  continuous, and fall keyhole make it unlikely that MDI can support
  anything between early June and late September. The exception would
  be studies during the 60-day continuous requesting 1 minute cadence

  NOTE: A GOES launch may cause a slip of a few days in the timing
  of the 60-day continuous.

- 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
* May 16-Jun 3  MEDOC Campaign, SM5
* Jun 3         Submode change to Submode 6, TBC
* Jun 4-25      26m Keyhole (Jun 09-20 34m Keyhole), SM5 or SM6(end)
* Aug 24, 31    EIT Shutterless #20, SM6, date TBC for Aug 31
* Aug 28-Sep 30 26m Keyhole (Sep 6-22 34m Keyhole), SM5 or SM6(end)
* Oct 5         Submode change to Submode 5, ~15 UT, TBC

* 06/05/01-06/06/15 SUMER Campaign
* 06/11/01-06/12/15 SUMER Campaign

  NOTE: The October 5 - 18 Submode 5 period was added after previous
  meeting, and will most probably replace the November 1 - December 15
  SUMER campaign (TBC).

- EIT Bakeout/Other

  Bakeout expected during June keyhole, dates TBD.

- Commanding outlook:

  Automatically updating, graphical weekly schedules are available at Current week is available at

  See AOB section for a summary of weeks 18-22.

  Note: 26m keyhole starts June 5. Extra SVM activities are needed
  throughout the keyhole, so schedule any NRT with SOCs.

  CDS is planning to carry on normal observations until June 9,
  continuing the THEMIS campaign. Help from SOC & FOT would be

  SOC: Should be no problem.

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
* '04/02-'05/05 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 (
* 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

* May 16-Jun 5  MEDOC Campaign

  and the calendar link therein for details.

  Address questions and problems to and
  the POCs, with copies to

  UVCS will do JOP158 (POC: Lucia Abbo) May 16-25, and Ulysses-SOHO
  quadrature campaign (POC: Giannina Poletto) May 26-June 8.

  Note LASCO pB campaign near end of MEDOC period; EIT synoptics only.

  Ulysses-SOHO Quadrature campaign will be May 26-June 7 (instead of June 8).

* May 21-Jun 9  Active Region/Sunspot Study, CDS/VTT/TRACE/THEMIS, 07-14UT,
                  POC: Andrzej Fludra, Local POC: CDS Planner

  From Andrzej Fludra:

  May 22-24 campaign with CDS/VTT/TRACE, approximately 2-3 hours/day
  May 25- June 9: CDS/THEMIS/VTT/TRACE, 5-7 hours/day

* May 25-30     MDI Continuous Contact

  No specific plans yet, default is Full Disk Magnetograms and Dopplergrams.
  Might go to high resolution FOV if there is a good reason to do so.

* May 26-Jun 7  Ulysses Quadrature, UVCS/Ulysses/SUMER

  SUMER support from June 1-3, then closing door.

* May 28-Jun 5  LASCO Extra pBs for 3D CME Study, EIT synoptic only

  NOTE: Only synoptic sets from EIT while this study is running.

  While this program is ongoing, Lasco has agreed to participate in the
  MEDOC South Polar Plumes in C2 May 30-June 3 06:00-09:00 UT.

* Jun 5-25      26m Keyhole (Jun 09-20 34m Keyhole)

* Jun 25-Aug 28 MDI 60 Day Continuous Contact

  The plan is Full Disk Magnetograms and Dopplergrams.  We will need
  to do at least one calibration and a tuning adjustment before the 60
  Day CC starts.  It's possible we will do an exposure update also, in
  which case, we need to do two calibrations (one before and one
  after).  So, plan on having some MDI engineering activities planned
  as soon as possible before June 25.  NRT and several hours of VC2
  will be required.

  Note: We are working on extra support from ESA's New Norcia station to
  ensure a more continuous campaign.

  NOTE: Dates may slip some due to GOES launch in the beginning of
  this period.

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

  NOTE: Dates changed since the meeting.

  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.

  TRACE has the dates as June 26th - Jul 7th, and a conflict with SST/DOT from
  Jul 3 - 6th.

* Jul 3-14      JOP181 Fine Magnetic Structures/Coronal Heating,
                  POC:, Local POC: TBC

  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 20        Sounding Rocket Launch, MOSES/CDS/EIT/TRACE, ~18 UT,
                  POC: Charles Kankelborg (, 

  NOTE: EUNIS launch previously scheduled for same day will be delayed
  at least a month.

  This study is during the continuous contact, so we will not be in
  record during the launch, but a second downlink station has been
  secured for 16:30-20:10 UT.

  CDS studies are under consideration.

  EIT will support with full-field, full-resolution 304 and 195  images
  around time of launch - will proably start synoptic set ~ 7 - 10 minutes
  before scheduled launch time.

* 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.

  Appears on TRACE calendar, but as a conflit with an SST/SUMER
  coordination August 17 - 20.

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

  (Dates changed)

* Aug 24, 31    EIT Shutterless #20, date TBC for Aug 31

* 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.

* 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 6-17      Fine Scale Structures, SUMER/MDI(TBC)/CDS(TBC)/THEMIS/DOT,
                  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.

* 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/DST,
                  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. 

* Oct 19, 26    EIT Shutterless, TBC

b) Intercalibration activities

  Last Intercal 1: April 6

  NOTE: No ICAL was done in weeks 18/19. Maybe one should be performed
  (with SUMER?) during the current MEDOC campaign, i.e. weeks 20-22?

  CDS is interested, as long as it doesn't interfere w/other MEDOC plans.
  SUMER prefers to wait until the October activities (TBD). EIT can 
  probably participate if an appropriate time can be found (during 
  periods with GSFC commanding ability).

  Next opportunity would be after the keyhole:

* Week 26       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 4         UVCS Star Observations (Tau Tau)
* Jun 5-7       Ulysses-SOHO Quadrature, UVCS/Ulysses
* Jun 8         UVCS Helium Focussing Cone
* Jun 24-30     Observations of the north polar coronal hole

  See their request diary for details:



  The MEDOC operations from May 16 - June 5 will primarily observe
  with det A, cf. MEDOC web page. We consider to have only a
  mini-campaign in the first wek of October (cf Fine Scale Structures
  study in Section 1) and no ops in November, still TBC.


  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 Jun 24        SPWG Meeting, TBC

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.

* Commanding outlook:

  Week 21 (May 23-29)   : D27 on Monday, part of Wednesday, Sunday.
  Week 22 (May 30-Jun 5): D27 on Monday, Wednesday. Daytime gaps
                          on Tuesday, Sunday.
  Week 23 (Jun 6-12)    : Keyhole - schedule any NRT with SOCs
  Week 24 (Jun 13-19)   : Keyhole - schedule any NRT with SOCs
  Week 25 (Jun 20-26)   : Keyhole ends on Saturday June 25.
