Latest Update: $Date: 2007/03/23 04:37:45 $ 
               $Author: tsiili $
               $Revision: 1.10 $
Change log is at the end of the document.

1. Boundary conditions

a) Orbit, attitude and manoeuvres

- SOHO is currently right side up

- manoeuvres

  May 29        roll, stationkeeping and momentum management (timing TBC)

  Aug 28        stationkeeping and momentum management
  Aug 30 or 31  roll (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 12-Sep 9  26 m keyhole
* Aug 19-Sep 2  34 m keyhole


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

  All available keyhole information is at
  http://soho.nascom.nasa.gov/soc/keyholes.html

  DSN planning is currently completed up to 3 June 2007.


c) 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
* Mar 16-Apr 30 SUMER Campaign
* Apr 1-30      SOHO/Hinode Campaign, SUMER/HINODE-EIS/STEREO-EUVI/TRACE
* May 4-17      SOHO/STEREO Campaign, EIT/MDI/STEREO-EUVI
* May 9,16      EIT Shutterless #27, 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
  operations.


d) Instrument maintenance activities

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


e) Others

  TRACE will have a summer eclipse season from about 12 May - 16 Jul (dates
  are TBC).



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)
* 2004/02/19--  JOP175 Extended Filaments at the Limb (#7135), 
                EIT/TRACE/LASCO/UVCS,
                POC: Chris St Cyr
* 2005/09/20--  JOP153/MMOP003 Future Major Flare Watch (#8007)

  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,
  except JOP175 getting half/full-res 304 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.


* Mar 16-31     SUMER technical ops in preparation for the Apr 1-30 campaign

  Ongoing.


* Mar 30-Apr 2  MDI Continuous Contact

  Current default plan is full-disk magnetograms and dopplergrams.


* Apr 01-27/30  SOHO/Hinode Campaign (#7201),
                  SUMER/CDS/HINODE-EIS/STEREO-EUVI/TRACE/MDI,
                  POC: Werner Curdt, Karine Bocchialini (MEDOC)
  
  SUMER is collecting proposals.  Deadline for SUMER proposals is 23 Mar
  2007.  SUMER has received 29 new proposals and requests to reactivate
  existing JOPs.

  A description of the proposals is avaialble under
  http://www.mps.mpg.de/homes/curdt/hinode/HINODE_cases.html.  Weekly plans
  for the entire campaign are in preparation and will also be accessible
  from the campaign page.  At present it is foreseen

  week 14: off-limb studies and studies that requested SOLIS; also studies
           that ask for an AR; on April 7/8 (Easter weekend) a 36 hour
           plume study with many supporting parties is planned
 
  week 15: all studies with quiet-Sun disk targets

  week 16: rest of studies that ask for an on-disk active region and
           studies that ask for IBIS

  week 17: studies that need VTT or Themis support, also studies that
           ask for a bright point target

  This plan in part depends on the availability targets and may be changed

  Presently it looks like the campaign can end on 27 April, unless special
  observations come up that require the time from 28 to 30 April.

  SUMER operations have started with testing and preparations 16-31 Apr
  (see above).  Science operations will be conducted from GSFC/EOF 1-15 Apr
  and from MEDOC with support at GSFC/EOF 16-27/30 Apr.

  CDS will also support (see also section 2c).

  CDS on JOPs: The campaign is likely to consist of a mixture of existing
  JOPs and new studies, hence neither updating an old JOP nor creating a
  single new JOP seems appropriate or necessary.

  Regarding JOPs - see section 3.

  MDI will also support.
  
  TRACE and STEREO-EUVI have also been included. TRACE will collaborate.

  UVCS will participate and plans to observe Apr.5-9.

  Observations described in JOP186 will take place as follows

  Week 14: 2-8th April
  Week 16: 16-22 April

  The following requests have been made by the JOP186 author (and modified 
by instrument comments):

  1) Observations are not scheduled during the CDS synoptic observation
     times (00:00 - 07:00 UT), so as to allow CDS support.

  2) Observations are scheduled to run from approximately 13:00 UT within
     the estimated 4-5 hour period relatively free of TRACE South Atlantic
     Anomalies (SAA).

  3) MDI high rate observations as permitted by DSN coverage on weeks 14 &
    16.  FD or HR mode will be driven by target selected.

  4) To allow for the time difference to Hinode planners in Japan specific
     details regarding precise timing, pointing should be decided by 15:00
     UT 2 days before the observations.


* Apr 16-27/30  SOHO/Hinode Campaign - MEDOC Campaign 17,
                  SUMER/MEDOC, POC: Karine Bocchialini

  MEDOC supports SUMER during part of the SOHO/Hinode campaign. This
  support is internally identified as MEDOC campaign 17. See also above and
  section 2c/SUMER.

  --> #MEDOC - changes, comments?

  
* Apr 23-29     JOP178 Filament and its Environment, TBC
                  THEMIS/SST/VTT/TRACE/SOHO/Hinode (all TBC), 
                  POC: Brigitte Schmieder

  MDI has been requested to participate and barring any conflicts with the
  Apr 26-29 continuous contact period, MDI should be able to support
  JOP178.

  CDS will support JOP178.

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


* Apr 26-29     MDI Continuous Contact

  Current default plan is full disk magnetograms and dopplergrams (TBD -
  may depend on requests by JOP 178).


* May 04-May 17 SOHO/STEREO Campaign, EIT/STEREO-EUVI/MDI, 
                  POC: William Thompson, TBC

  STEREO SECCHI requests synoptic EIT & LASCO data and prefers EIT to be
  obtaining full-resolution images. The SUMER/EIS campaign will take place
  in March and April to avoid EIT/SUMER submode conflict (i.e., allow SOHO
  to be in submode 6 during this campaign).

  SECCHI has also expressed interest in having Hinode to also join in the
  campaign (Hinode participation is TBC).

  The timing of this campaign is driven by the desire to conduct it when
  the STEREO spacecraft separation angle is in the range 7-10 degrees, but
  the timing is also constrained by the beginning of SOHO keyhole period on
  18 May.  The separation angle on May 4 is 6.5 degrees (and is acceptable
  to SECCHI). Timing remains TBC.

  EIT science planner for that period still TBD (for some months).  Simon
  can contact Kevin and Joe in the meantime.

  Description of JOP 187 ("Stereoscopic Observations of Coronal
  Structures"; http://sohowww.nascom.nasa.gov/soc/JOPs/jop187.pdf) has been
  drafted by Simon Plunkett.

  Still TBD, if the shutterless run #27 on May 9 will be included.

  MDI has also been asked to participate in this coordination for 4-17 May.
  Full disk, 1 minute cadence Magnetograms or high resolution, 1 minute
  cadence Magnetograms and Continuum images have been requested.  MDI can
  support either 4-17 May or 7-18 May (keep in mind that a keyhole period
  starts 18 May).

  CDS will participate.

  TRACE will be supporting these observations.


* May 7-13      Exceptional Ulysses Quadrature/Coordinated observations 
                  with radio scintillation measurements, 
                  UVCS/Ulysses/MERLIN, POC: Giannina Poletto

  Support from STEREO-SECCHI is being discussed by the POC. LASCO support
  may also be solicited (TBC).

  EIT support has not been asked yet.  STEREO campaign has higher priority
  in case of conflict.

  For additional and more detailed information on the quadrature, see also
  section 2c/UVCS.

  --> #LASCO - supporting?


* May 9, 16     EIT Shutterless #27, EIT/STEREO-SECCHI (TBD),
                POC (SECCHI): William Thompson

  The shutterless campaign during the SECCHI campaign may be dropped unless
  there is SECCHI interest in our keeping the shutterless in the plan.

  No word from STEREO yet, so our assumption is no shutterless campaign
  (TBC).

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


* May 14-20     Exceptional Ulysses Quadrature/Ulysses-SOHO Quadrature
                   together with Hinode, 
                   UVCS/CDS/Ulysses/Hinode(TBC)/STEREO-SECCHI(TBC),
                   POCs: Giannina Poletto, Giulio Del Zanna

  Support from STEREO-SECCHI is being discussed by the POC. LASCO support
  may also be solicited (TBC).

  EIT can support with synoptic images and CME watch only, unless asked for
  something different.

  The Hinode proposal for this campaign has been submitted and we are
  waiting for the Hinode response.  There are various technical issues
  associated with an off-limb observation, so there will be limitations in
  what we can do.

  UVCS time is allocated to do long exposures around 1.6 Rsun in the SW,
  for the Ulysses quadrature.  If no suitable AR will be available in the
  SW quadrant, but there is one in the SE limb, the connection with Ulysses
  will be missed and observations targeted to SE.

  Provisional support from CDS and STEREO/SECCHI, but details are to be
  worked out.

  For additional and more detailed information on the quadrature, see also
  section 2c/UVCS.

  --> #LASCO - supporting?


* Jun 13-17     MDI Continuous Contact, TBC

  Current default plan is full disk magnetograms and dopplergrams.  Timing
  TBC.


* Jul 18-22     MDI Continuous Contact, TBC

  Default campaign is full disk, 1 minute cadence magnetograms and
  dopplergrams.


* Aug 27-Oct 14 JOP178 Filament and its Environment, TBC
                  THEMIS/SST/VTT/TRACE/SOHO/Hinode (all TBC),
                  POC: Brigitte Schmieder
  
  MDI cannot support JOP178 in August or the beginning of September due to
  a SOHO keyhole (minimal support *might* be possible depending on the
  availability of 34m and 70m).  However, after the keyhole, MDI will start
  it's yearly 60 day Continuous Contact period and can only provide full
  disk, 1 minute cadence Magnetograms and Dopplergrams for JOP178. 

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


* 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.


b) Intercalibration activities


  Last Intercal 1: 22 February 2007

* Apr 16-20       ICAL01 (#7113), CDS/EIT, TBC

  Details and confirmation will be determined by the planners.

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



c) Individual instrument plans


MDI:

  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 back in focus 5, best focus for full-disk observing.


UVCS:

  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:
  http://cfa-www.harvard.edu/uvcs/observations/obst.html.

  A document from Steve Suess and Giannina Poletto discussing the
  Ulysses-SOHO quadrature geometry is available from Michael Uzzo and also
  at http://sohowww.nascom.nasa.gov/soc/UlyPosAng2007-2008.pdf.


CDS:

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

  Joint observations with EIS and other Hinode instruments are top priority
  for CDS for the next several months, including through the period of
  SUMER/EIS campaign in Mar-Apr 2007.  Detailed plan TBD.

  Detailed plans of Hinode instruments are made available to CDS at a short
  notice, usually one day in advance.  This is not fully satisfactory but
  we understand that the Hinode team are very busy at this stage.  CDS
  planners respond as appropriate.  If SOHO SOCs have access to Hinode
  weekly plans, forwarding them to us would be appreciated.

  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.


LASCO/EIT:

  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?


SUMER:

  The SOHO/HINODE spring campaign (see also section 2a) is scheduled now
  from 1-30 Apr.  SUMER operations including test runs etc.  have started
  on 16 Mar. No submode change was made between the end of the Feb keyhole
  and 16 Mar.

  SUMER science planners for the campaign:

  22 Mar Germerott  
  26 Mar Curdt      (preparation phase)
  02 Apr Tothova
  09 Apr Kucera
  16 Apr Teriaca    (operated from MEDOC, with local support at EOF)
  23 Apr Madjarska  (operated from MEDOC, with local support at EOF)

  SUMER is collecting proposals, existing JOPs can be reactivated and new
  studies can be submitted. Before acceptance any study will be critically
  rated by an evaluation board.  Priority will be given to SOHO/EIS
  collaborations. TRACE and STEREO/EUVI support as well as GBO
  co-observations (and self-evidently CDS, EIT, MDI) would be highly
  appreciated.

  There are tentative plans for another SUMER campaign in October/November,
  details are TBD.


TRACE:

  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 27 April or Friday 20 April after daily & weekly meetings

  UVCS:  27 April is better
  TRACE: 27 April (no-one present on 20 April)

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
  http://www.isas.jaxa.jp/home/solar/hinode_op/

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

* 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.
