Change log is at the end of the document.

1. Boundary conditions

a) Orbit, attitude and manoeuvres

- SOHO is in normal roll (0 deg) position

- manoeuvres

  May 29        roll, stationkeeping and momentum management

  Aug 28        stationkeeping and momentum management
  Aug 30 or 31  roll (timing TBC)

  Nov 20        roll, stationkeeping and momentum management
                (timing TBC)

b) Communications with the spacecraft

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

* May 18-Jun 5  26 m keyhole
* May 22-May 31 34 m keyhole

* Aug 11-Sep 9  26 m keyhole
* Aug 19-Sep 2  34 m keyhole

* Nov 15-Dec 2  26 m keyhole
* Nov 19-Nov 28 34 m keyhole

- The need and approach to reduce FOT manpower requirements needed for
  complex operations during the keyhole remains in effect until further 

  All available keyhole information is at

c) KNOWN submode dependent activities/submode changes:

* TOO           JOP153/MMOP003 Future Major Flare Watch (SM5 if SUMER
                observes target, SM6 otherwise)
* Oct 22-Nov 4  Active region morphology studies (TBC), SUMER/VTT/
                  HINODE (TBC)/TRACE/STEREO
* Jul 26, Aug 2 EIT shutterless #28 (timing TBC)
* Nov 1,8       EIT shutterless #29 (timing TBC)

- 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.

- 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

d) Instrument maintenance activities

   EIT bakeout periods will be during keyholes.  Dates and times are
   defined when the DSN schedules become available.

   EIT in bakeout for May keyhole 18-24 May.

e) Others

  TRACE will have a summer eclipse season from about 24 May - 16 Jul (dates
  are TBC).

  Hinode eclipse season 7 May - 10 Aug.

--> #Hinode - changes, comments?

2. Priorities for the coming month and more

a) Joint observing plans and campaigns

Continuing campaigns:

* 2002/02/25--  JOP136 Default RHESSI Collaborations (#6850),
                POC: Tero Siili
* 2003/05/13--  Default CDS Co-observations with TRACE (#6950)
* 2005/09/20--  JOP153/MMOP003 Future Major Flare Watch (#8007)
* 2007/03/20--  Default CDS/Hinode-EIS co-observations (#7200)

  Campaign #6850 is for "individual instrument studies" selecting an active
  region target [partially] influenced by the Max Millennium target
  selection to maximise chances of serendipitous co-observations.

  EIT supports all with half/full-res 195 A CME watch in submode 5/6. As
  long as the spacecraft 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.

  The relevance and continuation (whether the originators have
  enough/alternate data) of these campaigns (except perhaps for RHESSI) is
  under review.

* Jul 3-8       JOP 178 Filament and its Environment (TBC)/
                   JOP157 Bright points in active regions (TBC),
                   SOHO/THEMIS, POC: Brigitte Schmieder

  Proposal for consideration from the POC. JOP 157 would be used, if a target
  of opportunity appears. SOHO supports are solicited.

  CDS will support.

  MDI can support with either HR or FD Magnetograms.

--> #ALL - changes, comments, supports?

* Jun 13-17     MDI Continuous Contact, TBC

  Current default plan is high-resolution magnetograms in FOC4.  Timing

* Jul 18-22     MDI Continuous Contact, TBC

  Default campaign is full disk, 1 minute cadence magnetograms and

* Jul 1-Aug 5   JOP 188 Prominence Mass Composition and Variability Study,
                  POC: Gary Kilper

  A study on the relative abundances of hydrogen and helium in prominences
  and on their trends in spatial distribution and variability over time is
  proposed. The method is measurement of the continuum absorption due to
  photoionization for EUV observations and of the absorption in H-alpha
  (6563 A) and He I (10830 A).

  Timing is TBC.

  Supports from the listed instruments are solicited.

  CDS will consider supporting on selected dates as time allows, but need
  to receive the proposal and details of CDS observations and studies.

  EIT will support. This item needs approval as a JOP. Who will lead first
  run at EOF?

  TRACE will support, but JOP 178 will get priority during its conflicting

  MDI will support with synoptic Continuum Images when in high rate.

--> #STEREO-EUVI, #Hinode-SOT, #Hinode-EIS - supports?

* Aug 3-31      JOP 189 Physical mechanisms driving solar microflares and
                  supergranular network dynamics - relevance for coronal
                  heating, CDS/EIT/MDI/Hinode-EIS/Hinode-SOT/Hinode-XRT/
                  RHESSI/TRACE/DOT/KSO, POC: Jan Rybak, Peter Gomory

  Detailed campaign/coordination information can be found at 

  The Hinode/EIS,SOT,XRT application will be sent to SSCs on the week
  starting 28 May 2007.

  Having in mind the SOHO keyhole we plan to request for the Hinode support
  mainly after Aug 17 expecting the SOHO will be supporting (at least)
  partially until Aug 17 in the time interval 07:00-13:30 UT (for UT times,
  see also the Aug 5-18 campaign).

  Supports from the listed instruments are solicited.

  CDS will support on selected dates, as time allows.

  EIT will support through ~ August 9, but keyhole begins August 10. This
  item needs approval as a JOP. Who will lead first run at EOF?

  TRACE will only support 20-31 Aug.

  HR Filtergrams and Magnetograms when target in the HRFOV. FD Magnetograms
  and Dopplergrams otherwise.

--> #Hinode-EIS, #Hinode-XRT - supports?

* Aug 5-18      Filament/Cavity-CME-ICME IHY-CIP campaign, 
                  SOLARC/ProMag/MWA/RHESSI, POC: Terry Kucera

  As part of the International Heliophysical Year (IHY), we propose an
  observing campaign in the time interval August 5-18, 2007 which will
  follow a targetted filament from East to West limb, in order to study its
  morphology, evolution and activation, and quantify its magnetic and
  plasma properties. Our study will be greatly enhanced should the filament
  erupt as a CME, and if it does, we will also examine in situ observations
  in order to link any pertinent ICME and magnetic cloud observations to
  their filament source.

  The campaign is a conglomeration of four International Heliophysical Year
  (IHY) Coordinated Investigaton Programmes (CIPs) which are headed up by
  Barbara Thompson, Sarah Gibson, Holly Gilbert and Pat McIntosh.

  The most important time of day for campaign participation would be 17:00
  -- 20:00 UT, the best observing period of Mauna Loa. The full Mauna Loa
  observing day can run from 16:30 -- 02:30 UT. Scheduling spacecraft
  supports to these times would help to interleave with the JOP 189, which
  has its ground-based support focus on Canary islands and in Europe.

  CDS has not heard from the POC yet and is awaiting for contact, but is
  likely to participate in some form.

  MDI inquired, whether its support is solicited.

  JOP? EIT can support through CME watch. Keyhole begins August 10.

--> #Hinode-EIS, #Hinode-XRT, #Hinode-SOT - changes, comments?

* Sep 10-Nov 11 MDI 60-day Continuous Contact (TBC)

  DSN schedule is not yet known (see section 1b).  MDI will run 1 min
  cadence, full disk magnetograms and dopplergrams.

* Oct 22-Nov 4  Active region morphology studies (TBC), SUMER/VTT/
                  HINODE (TBC)/TRACE/STEREO

  See section 2c for further details.

  CDS will join the campaign - please add CDS Planner e-mail address to the
  mailing list.

  TRACE has slightly different dates: 21 Oct - 1 Nov. The discrepancy is
  being investigated.

--> #Hinode, #STEREO - changes, comments?

b) Intercalibration activities

  Last Intercal 1: 16 May 2007

* June 11-15    ICAL01 (#7113), CDS/EIT, TBC

  Details and confirmation will be determined by the planners. 

  EIT: ICALs are OK except (usually) during the weeks of shutterless.

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 70 m antenna availability at
  the time.  MDI may also downlink select magnetograms in the 5 kbps
  telemetry if no 70 m passes are available at least every 2 days for Mag
  dump in the 160 kbps telemetry.

  All requests for MDI support need to be made several months ahead of time
  and sent to mdi-ops(at)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 in focus 5, best focus for full-disk observing. MDI will be in
  best focus for high-resolution observing (FOC4) at the end of the
  May/June 2007 Keyhole until the end of June.

  The MDI data archive relocation at Stanford University (scheduled for the
  week of 28 April through 6 May, 2007) was completed successfully,
  archiving and data export are working normally.


  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:


  For details see http://solar.bnsc.rl.ac.uk/scientificops/request.shtml.

  Given the extended duration of the Ulysses-SOHO quadrature, CDS will
  carry out several observations at a convenient date selected at a
  relatively short notice.

--> #CDS - changes, comments?


  EIT: 195 A CME watch plus synoptics at 6-hour cadence, as usual. Full-res
  CME watch whenever we're in submode 6.

--> #LASCO - changes, comments?


  There are tentative plans for a campaign from Oct 22 to Nov 4, working
  title "Active region morphology studies, joint observations of SUMER,
  VTT, HINODE, TRACE, STEREO", and also accomodating studies, which could
  not be run during the spring campaign. Observers, who are interested in
  support from participating instruments are highly requested to
  prepare/update a detailed JOP/HOP description and to contact the
  instrument representatives. Hinode participation is still TBC.


  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.

  For TRACE summer eclipse season see section 1e.

3. Any other business

* Next SPWG:

  Friday 22 or 29 June after daily & weekly meetings

--> #ALL - changes, comments?

  CDS:	 No comment
  EIT:	 No comment
  SUMER: No comment
  TRACE: No TRACE representative on 22 June.
  MDI:   Either day is OK.
  UVCS:  22 June is preferable

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.

* Future Mercury and Venus transits: SOC is requesting the Flight Dynamics
  Facility (FDF) to provide estimates and data for not only disk, but also
  for coronal transits.  For this purpose FDF needs a criterion
  (radial/angular distance from Solar disk centre) to define the coronal
  transits.  Currently FDF has been instructed to use
  SOHO/Sun/[Mercury,Venus] angle of (35 arcmin (from centre of Solar disk)
  as criterion.  Instrument teams are requested to provide the SOC with
  information on whether a larger angle is applicable.

* Hinode operational and planning information can be found from

* STEREO operational and planning information can be found via 
  http://stereo-ssc.nascom.nasa.gov/, more specifically from 

* The SOHO JOP/ICAL database and the web pages are now the Solar JOP/ICAL
  database and web pages. This is due to anticipated increased
  contributions by and collaborations as well as intercalibrations with
  STEREO and Hinode.

* To provide more unambiguous identification, individual instruments on
  board spacecraft other than SOHO will be as of this SPWG be referred to
  with notation SPACECRAFT-INSTRUMENT, for example Hinode-EIS.

* The Project Scientist has decided that submission of the Inputs to the
  Activity Plan (IAPs) will change to be voluntary.  The PS has informed
  the SOHO community of the change on 22 Feb by e-mail.

* The FOT will begin testing the automation procedures on the week
  beginning 19 March. The passes will continue to be manned until after an
  operational readiness review and both agencies agree to a change in the
  mission management plan, both of which won't be for at least a couple of
  months, after we have significant experience with the automation.

* New JOP vs. modified existing JOP rules-of-thumb: New JOP, if/when
  scientifically or qualitatively new type of a coordination is set up;
  modified JOP, when the investigation (the foci or targets thereof)
  remains essentially the same but new instruments/spacecraft/GBOs/etc are
  brought to bear.
