FINAL MINUTES FOR SOHO 28 Sep 2007 SPWG MEETING

1. Boundary conditions

a) Orbit, attitude and manoeuvres

- SOHO is in right side up roll (0 deg) position

- manoeuvres

  Nov 27        roll, stationkeeping and momentum management
                (timing TBC)


b) Communications with the spacecraft

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

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

* Feb 4-Mar 2   26 m keyhole
* Feb 11-24     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


c) KNOWN submode (SM) dependent activities/submode changes:

* TOO           JOP153/MMOP003 Future Major Flare Watch (SM5 if SUMER
                observes target, SM6 otherwise)
* Oct 11, 17    EIT shutterless #29 (SM6)
* Oct 26-29     SUMER campaign preparations (SM5)
* Nov 6         EUNIS Sounding Rocket Launch, 16:49-18:49 UT (SM5, SUMER
                supports)
* Nov 2-16      Polar Plume and Active Region Morphology Studies, 
                SUMER/CDS/MDI/UVCS/EIT/VTT/HINODE/TRACE/STEREO-EUVI (SM5)
* Jan 23, 30    EIT shutterless #30 (SM6)

- 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 winter eclipse season is 13 Sep 2007 - 13 Mar 2008. Hard eclipses
  started on 23 Sep 2007.

  Unattended automated passes will begin as of Nov 8 2007.

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 (#8008)
* 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. It is
  clear that STEREO-EUVI provides adequate "context" information for RHESSI
  flare observations. Routine EIT submode and resolution switches are
  probably no longer needed.


* Oct 11,17      EIT Shutterless #29


* Oct 26-29      MDI 3-day Continuous Contact

  The more exact times are Oct 26 19:25 UTC to 29 Oct 05:25 UTC. The
  default observing campaign for the 3-day Continuous Contact will be full
  disk Magnetograms/Dopplergrams.  However, MDI may do high resolution
  observations with Hinode (TBD).


* Oct 26-29     SUMER campaign preparations (timing TBC)

  Submode change will tentatively be on Oct 26, followed by SUMER door
  opening and setup as of Oct 27. More comprehensive description of the
  Oct-Nov 2007 SUMER-Hinode set of collaborations is below under title
  "Polar Plume and Active Region Morphology Studies" for dates Nov 2-16.


* Oct 30-Nov 5 JOP197/HOP044 Multi-wavelength observations of coronal hole
                  plumes at solar minimum (#7243), CDS/SUMER/UVCS/
                  Hinode-EIS/Hinode-SOT/Hinode-XRT/STEREO-COR1/STEREO-EUVI/
                  STEREO-SECCHI/TRACE/, POC: Giulio Del Zanna

  A Hinode HOP (titled "Multi-wavelength observation of coronal hole plumes
  at solar minimum") asking for a Hinode observing period 30 Oct - 5 Nov
  has been proposed by Del Zanna. The proposal has been accepted, and
  assigned the number 44
  (http://www.isas.jaxa.jp/home/solar/hinode_op/hop.php?hop=0044).

  MDI hasn't gotten a request for this. SOC response: according to the JOP
  description(http://sohowww.nascom.nasa.gov/soc/JOPs/jop197.txt), MDI
  support is not requested.

  CDS will participate.

  A web site/campaign interface has been set up for the late Oct-Nov
  campaigns and JOPs involving SUMER or Hinode. The URL is
  http://www.mps.mpg.de/homes/theissen/scr/planning/index.html. See also
  the entry for "Polar Plume and Active Region Morphology Studies" below.


* Nov 1-16      JOP196 Detection of waves in the solar atmosphere (#7244),
                  CDS/SUMER/Hinode-EIS/Hinode-SOT/Hinode-XRT/STEREO-EUVI/TRACE/
                  VTT-TIP2, POC: Luca Teriaca

  CDS will participate.

  the entry for "Polar Plume and Active Region Morphology Studies" below.


* Nov 2-11      JOP198 Spectral Observations of Spicule Dynamics (#7245),
                  SUMER/Hinode-EIS/Hinode-SOT/Hinode-XRT/TRACE/NSO-DST,

                  SUMER/CDS/MDI/UVCS/EIT/VTT/HINODE/TRACE/STEREO-EUVI,
		  POC: Davina Innes

  Note that these dates have changed. JOP leaders have been contacted.

  A web site/campaign interface has been set up for the late Oct-Nov
  campaigns and JOPs involving SUMER or Hinode. The time period is 29 Oct -
  18 Nov. The URL is
  http://www.mps.mpg.de/homes/theissen/scr/planning/index.html. The
  interface is hopefully self explanatory but Davina Innes will be writing
  to planners and observers to make sure that they are OK with it. All
  teams participating in the SUMER campaign of November (now including the
  EUNIS flight) are strongly encouraged to use this tool for communicating
  observational details. It will serve for the overall organisation of the
  campaign as well as for the daily planning. Please check and complete
  your entries.

  NOTE: the instrument planners CAN but do not HAVE to upload to/through
  the web interface. It is there as an alternative to emailing the
  observers. Some observers ask for confirmation that their target requests
  got through.

  To facilitate the work of planners a (new) feature "links to timelines"
  is included. From there one can go straight to the SoHO targets, TRACE,
  Hinode-SOT, MDI timelines. If these links are kept up-to-date then there
  is no more need for uploading by the instrument planners. Further links
  will be added if needed and available.

  The overall schedule for the proposed JOPs/HOPs will be frozen very soon.

  CDS will join the campaign - please add CDS Planner e-mail address to the
  mailing list. All Hinode and SUMER users are invited to submit requests
  for complementary CDS observations. Send requests to 
  A.Fludra (at) rl.ac.uk and P.R.Young (at) rl.ac.uk.

  There are several JOPs associated with this campaign. These are listed
  separately on the calendar (see above and below) and will have separate
  campaign numbers when the time gets closer.

  Werner Curdt writes that observers are requested to contact all
  instrument teams involved and to timely submit JOP/HOP descriptions with
  all the observational details approved. The responsibility for the
  proposed studies rests with the observers. Note, that TRACE will be in
  eclipse at that time, and EUV observations will be constrained.

  Several teams requested a POC for this entire time instead of individual
  JOP leaders. Davina Innes will be the POC from Lindau.

  POC in ISAS:                     Enrico Landi (TBC)
  POC in MPS:                      Davina Innes
  SUMER planners and POCs in GSFC: Udo Schuehle, Dietmar Germerott

  MDI will support the Polar Plume & AR study.  The Helioseismology study
  with Hinode has been changed to Dec 3-6.

  The TRACE team was not informed of this change in dates for the SUMER
  campaign and we have not heard any details about what will be run. I have
  changed the dates on our calendar, but it is still not clear what is
  running when. Also TRACE will likely decide on the level of support on a
  day to day basis. Also please be advised that we will be further into our
  eclipse season.


* Nov 2-16      JOP104 Doppler Shifts in X-ray Jets (#7242),
                  CDS/EIT/SUMER/UVCS(TBC)/RHESSI/TRACE(TBD),
                  POC: Davina Innes

  Support request list for this run of the JOP remains TBC.

  TRACE can support and is requesting for more information on the type of
  support requested.

  No EIT participation defined. Regular synoptics and half-res CME watch in
  195 A are assumed to suffice.

  CDS will support.

  MDI will support JOP190. The Helioseismology study with Hinode has been
  changed to Dec 3-6.  Since the 60-day continuous contact is moved, MDI
  can provide either full-disk or high-resolution mode observations. MDI
  can provide observations to all of the requested JOPs if we have high
  rate data and if the targets for each do not conflict (ie, one JOP wants
  high-resolution and another wants full-disk or some other pointing in
  high-resolution mode).  MDI will not switch observing modes on timescales
  less than 24 h.

                  TRACE, POC: Gerry Doyle

  Timing is TBC.


* Nov 6         EUNIS Sounding Rocket Launch, 16:49-18:49 UT,
                  CDS/MDI/SUMER/EIT (all TBC), POC: Jeff Brosius, 
                  Douglas Rabin, Roger Thomas
  
  The launch has been rescheduled from Oct 30 to Nov 6.

  For a 2007 November 6 flight, the EUNIS launch window is 16:49 - 18:49
  UT.  EIS will start to observe during this window immediately after
  Hinode exits the South Atlantic Anomaly (for which predicted times should
  be available about two weeks before launch), and EUNIS will launch 20
  minutes after that.

  Nov 7 is the likely backup launch date, but details with the White Sands
  range remain to be resolved and changes are possible up to last minute.

  Possibilities of obtaining a backup DSN antenna for Nov 6 (2 h centred
  around the launch time) will be investigated. The DSN schedule for that
  week will not be negotiated until Oct 5 at the earliest.

  From Jeff Brosius:

       Ideally, we will get a sequence of four EIT images both before and
       after the flight, with the He II images obtained at the beginning
       and the end of the flight (similar to what was done on 12 April
       2006).  These are all valuable for context, but the He II images are
       especially useful for precise coalignment of the EUNIS slit onto the
       solar disk.  Ideally, we will also get at least one NIS4W raster
       (which takes CDS 2 hours to complete) of the target region.  This
       will enable a direct cross-calibration with CDS (similar to what we
       are doing for the 2006 flight).  A 96-minute MDI magnetogram will be
       sufficient.  SUMER observations will expand the temperature coverage
       of the campaign and perhaps enable further cross-calibration.

  Note from SOCs: DSN backup and its effect on MDI supports?

  CDS will support, need more details.

  Some details of the SOHO observing plans from the 12 April 2006 flight
  are given below.  The 2006 observing sequence worked well, and J. Brosius
  would like to use a similar plan for the 6 November 2007 flight --- with
  the times adjusted to accommodate the actual launch time.  For the 2006
  flight, EUNIS launched at 18:10 UT and began taking science observations
  at 18:12 UT.

  CDS ran the following sequence:
  GISAT/v132  x1   13:37 - 15:02    * TIME-TAGGED
  NIS4W/v62   x1   15:07 - 17:10    * TIME-TAGGED
  NIS4W/v62   x1   17:10 - 19:13

  EIT is requested to run the following sequence of full field-of-view, full resolution
  (1024 by 1024 pixels) images:

  284 image - 17:53 UT
  171 image - 17:59 UT
  195 image - 18:06 UT
  304 image - 18:12 UT
  304 image - 18:20 UT
  171 image-  18:27 UT
  195 image - 18:33 UT

  Ths sequence is identical to the 12 April 2006, except for the order of
  the first two images.

  The target for the 6 November 2007 flight will likely be near disk
  center, and will be decided one day before launch by the EUNIS team.
  Will that be too late?  5 Nov is a Monday.

  MDI will support the EUNIS Rocket Launch with either 1 minute, FD
  Mag/Dopplergrams 96 minute synoptic Magnetograms/Continuum images if we
  have high rate data at the time (ie. we have a backup antenna) or with 96
  minute synoptic Magnetograms if we do not have high rate data during the
  flight (ie. SOHO is in record).  If we do not have high rate during the
  flight, then MDI will not be able to support any SUMER/Hinode JOPs that
  might be running in parallel with the flight.

  EIT: Assuming launch does not slip into keyhole, should be able to
  support as requested.

  A web site/campaign interface has been set up for the late Oct-Nov

  A Hinode HOP has been proposed by Mari-Paz Miralles and Enrico Landi for
  an observation period Nov 6-17.

  CDS request to be kept informed of pointing. May co-observe if target of
  interest to CDS.

  SUMER is the only requested SOHO support.  A follow-on e-mail to request
  clarification on desired TRACE supports has been sent.

  Allocated SUMER observation times are:

  from 2007-11-04T00:00:00 to 2007-11-04T06:00:00
  from 2007-11-11T18:00:00 to 2007-11-12T00:00:00

* Dec 2--->2008 Exceptional Ulysses Quadrature (ends May 28, 2008)


* Dec 3-Feb 3   MDI 60-day Continuous Contact

  The default observing campaign will be 1-min cadence full-disk
  Magnetograms/Dopplergrams (p30vr_fd_m1 - 1100) with the exception of high
  resolution observing for a helioseismology study with Hinode 3-6 Dec
  2007.


* Dec 17-23     Ulysses-SOHO Quadrature Observations, UVCS/Ulysses,
                  POC: Giannina Poletto


* Jan 23,30     EIT Shutterless #30


* Mar 20-Apr 16 Whole Heliosphere Interval (WHI) Campaign (TBD), 
                  CDS/MDI/UVCS/TRACE(TBC), POC: Sarah Gibson

  The current thinking is that this set of campaigns (associated with the
  International Heliospheric Year - IHY) will be structured as multiple
  JOPs, but be centrally coordinated in the same fashion as the Aug 2007
  run of JOP194.

  The tentative JOP titles are
    * Linking the Corona to the Solar Wind at Ulysses
    * Origin of the Slow Solar Wind/Streamer Study
    * Coronal Hole Boundary
    * Quiet Sun
    * (Target of Opportunity) Active Region
    * (Target of Opportunity) Polar Crown Filament/Cavity

  JOP descriptions are expected by the Nov SPWG meeting.

  UVCS will support.

  TRACE has received a request to support.

  MDI can provided data for this, but MDI may be in another 60-day
  Continuous Contact, hence can only provide 1 minute full disk
  Magnetograms and Dopplergrams and 96 minute synoptic Magnetograms and 96
  minute synoptic Continuum images when we have high rate.  High-res
  observations would be very unlikely.

  CDS will participate.


b) Intercalibration activities


  Last Intercal 1: 19 September 2007


* Oct 15-19   ICAL01 (#7113), CDS/EIT/Hinode-EIS, TBC

  Possible EIS collaboration. CDS views Hinode-EIS participation as
  extremely important.  EIS and Stereo have been added to the Campaign
  #7113 description.

  Details and confirmation will be determined by the planners. 

  EIT: ICALs are OK except (usually) 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 for best focus for FD observing and will stay 
  there at least until March 2008.


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


CDS:

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


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. Hope never to change until the
  Bogart mission.


SUMER:

  Nov 2-16      Polar Plume and Active Region Morphology Studies, 
                  SUMER/CDS/MDI/UVCS/EIT/VTT/HINODE/TRACE/STEREO-EUVI

  See details in Section 2a for list of JOPs/HOPs to be run at this time.

  There are tentative plans for another SUMER campaign from April 21 to
  May 4, 2008.


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.

  During our fall eclipse season that starts in October, we will accept
  observing requests through Novemeber 1st. Any observations that are to
  take place after November 1st will be evaluated in October once eclipse
  season has started and then we will decide what makes sense for us 
  to support. 

  During the period of deepest eclipses (Nov. 16 - Feb. 15) of its winter
  eclipse season, TRACE will be operated by three command loads per week
  (Mondays, Wednesdays, and Fridays). TRACE will accept a limited number of
  JOP requests, giving preference to those that involve multiple
  observatories (in space and/or on the ground), provided that their
  targets can be specified on a schedule that is compatible with the
  reduced frequency in instrument command loads during the winter eclipse
  season).

3. Any other business

* VC3 and non-ranging handovers

  From MDI/Gregory: for automation (actually for ops in general), I would
  like to suggest that we do away with VC3 (except for non-ranging)
  handovers.  I know that during long overnight contacts, the FOT
  traditionally go to VC3 while still giving periodic VC2 around ALT times
  (refer to the "Standard Ops Policy" OCD submitted 17 Oct 2005 for
  details).

  Status: the required modifications to automation software may be
  extensive at this point. Feasibility as well as resource expenditure
  vs. benefits are being assessed. Decisions are not expected until early
  Sep 2007 at the earliest.

  Issue is closed. MDI will not request this.


* Next SPWG:

  Friday 26 October after daily & weekly meetings.


The rest are FYI items:

* If anyone has projects that require high rate (i.e. 1 minute cadence and
  anything other than 96 minute synoptic Magnetograms) 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/. For contacts with the
  Hinode team(s), some guidelines... General discussion of campaign plans
  that are evolving and are several months away should go to the Hinode
  instruments' science schedule coordinators (SSCs). If a single clearly
  primary Hinode instrument can be identified, the campaign coordinators
  should contact the SSC of that instrument only. The Hinode instrument
  planners will not be involved until the detailed pointings and such are
  being discussed. The SSCs for the different Hinode instruments are:
  EIS: Len Culhane, John  Mariska, Tetsuya Watanabe
  SOT: Thomas Berger, Takashi Sekii
  XRT: Leon Golub, Kiyoto Shibasaki

* 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. Lead time for special
  requests for STEREO supports should be at least a month.

* 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.

* Automation and unmanned passes. The operational readiness review has been
  completed and transition to unmanned passes approved. The nighttime
  passes will transition to being unmanned around beginning of
  October. This transition will limit instruments' abilities to carry out
  non-routine operations.

* 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.

* SOHO calendar email notifications: a new mailing list for notifications
  of changes in the SOHO calendar has been taken into use. Distributed
  changes are decided upon by the SOCs to be relevant (as opposed to
  corrections of typing errors, etc.). Examples are schedule changes, added
  and deleted campaigns and so forth. To join the list send e-mail to the
  SOCs.
