FINAL MINUTES FOR SOHO 28 Mar 2008 SPWG MEETING

1. Boundary conditions

a) Orbit, attitude and manoeuvres

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

- manoeuvres

  To the degree possible, manoeuvres take place during the last days of
  34-m keyholes.  Currently proposed or set manoeuvre dates are:

  May 19 (TBC)	station-keeping, momentum management, roll

  Aug 19 (TBC)  station-keeping, momentum management
  Aug 22 (TBC)	roll



b) Communications with the spacecraft

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

  Keyhole dates for the next 6 months:

* May 7-25      26 m keyhole
* May 11-21     34 m keyhole

* Aug 01-30     26m Keyhole 
* Aug 08-22     34m 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. Direct link to the list of
  estimated dates for future keyholes is
  http://sohowww.nascom.nasa.gov/soc/keyholes.txt.

- DSN D45 and D65 (34-m) antennae status

  D45 and D65 have been and currently remain downlink/telemetry-only, but
  are in the process of being upgraded with uplink/commanding capabilities.
  The estimated time for the transmitters to change to operational status
  is late April or early May.



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

* TOO           JOP153/MMOP003 Future Major Flare Watch (SM5 if SUMER
                observes target, SM6 otherwise)
* Apr 3-16      SUMER support for the WHI (SM5)
* Apr 23,29     EIT Shutterless #31 (SM6)
* Jun 20-30     SUMER observing TBC (SM5)
* Jul 23,30     EIT Shutterless #32 (SM6)
* Nov           SUMER campaign TBD (SM5)

  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.

  For details of the SUMER observations Apr 3-16, see the WHI entry in
  section 2a.

  The Jun 20-30 SUMER observations are in support of JOP 213 (see also
  section 2a) and in coordination with UVCS.



d) Instrument maintenance activities

  EIT bakeout periods will be during keyholes.  Dates and times are defined
  when the DSN schedules become available. EIT will provide info as soon as
  possible on bakeout dates.



e) Others


  Daylight Saving/Summer Time starts in the European Union on 30 Mar 2008
  at 1 UT. After the change

     GSFC local = UT - 4 h 
                = Central Europe - 6 h
                = UK - 5 h 
                = Japan - 13 h

  TRACE summer eclipse season begins on 10 May 2008.

  Unattended automated night passes for SOHO began October 6 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.


* Dec 2-May 28  Exceptional Ulysses Quadrature

  Observations of the Ulysses spacecraft are expected to cease soon (from
  weeks to few months) --- quite possibly before the end of the quadrature
  period.


* Mar 3-May 4   MDI 60-day Continuous Contact

  The default observing sequence will be 1 min cadence, full disk
  Magnetograms and Dopplergrams along with our usual 96 min synoptic
  Magnetograms and synoptic Continuum images when in high rate.

  To avoid problems with transmitter masks at the end of passes during MDI
  continuous, DSN has requested we bring the carrier down 30 min before the
  end of pass.  As a result, the last 30 min of all MDI continuous contacts
  will be TM only.  For ranging passes, the spacecraft will be transitioned
  to record ~1 h before the end of the pass.  The station will drop the
  carrier and re-sweep into receiver 2.  The spacecraft will then be
  transitioned back to VC2 and VC3.


* Mar 30        Daylight Saving/Summer Time starts in the European Union
                at 1 UT   

  See also section 1e.


* Mar 20-Apr 16 Whole Heliosphere Interval (WHI) Campaign, 
                  CDS/CELIAS/COSTEP/EIT/LASCO/MDI/SUMER/UVCS/TRACE/
                  Hinode-EIS/Hinode-SOT/Hinode-XRT/STEREO-SECCHI/
                  STEREO-PLASTIC, 
                  POC: Sarah Gibson, TBD

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

  The targetting calendar (with the most up-to-date information) can be
  found at http://ihy2007.org/WHI/WHI_targets.shtml.

  As a heads-up of what to expect: due to Hinode constraints, it is
  probable that JOP focus time for overlapping with Hinode observations
  will be 1100-1500 UT, rather than 1600-2000 UT as previously planned.
  Targetting emails/calendar for each individual JOP will be the final
  authority on times.

  The tentative JOP titles and timings are:

  Mar 20-26     JOP 201 Linking the Corona to the Solar Wind at Ulysses,
                  Campaign #: 7265,
                  EIT/LASCO/UVCS/Hinode-EIS/Hinode-SOT/STEREO-SECCHI/
                  TRACE/Global Muon Detector Monitor/EISCAT/HSO/IPS/Nancay/Ooty
                  POC: Giannina Poletto,
                  URL: http://web.hao.ucar.edu/~sgibson/WHI/WHI-HOLEULYSSES.html

  NOTE: Observations of the Ulysses spacecraft are expected to cease
  soon. The emphasis of JOP 201 may shift to polar plumes.

  NOTE: JOP 201 is essentially the same as HOP 0064.

  Objective is twofold: 1) infer the outflow speed wind profile in 
  plume/interplume regions, 2) characterize the evolution in time of the 
  morphological/physical properties of plumes.

  The UVCS target for JOP 201 is polar plumes in the south coronal
  hole. UVCS is supporting JOP 201 for the whole duration.

  Mar 27- Apr 2 JOP 202 Origin of the Slow Solar Wind/Streamer Study,
                  Campaign #: 7266,
                  CDS/EIT/LASCO/UVCS/ACE/Geotail/Hinode-XRT/
                  STEREO-SECCHI/TRACE/Ulysses/EISCAT/MLSO/Nagoya/Nancay/
                  OOTY/SMEI
                  POC: Leonard Strachan
                  URL: http://web.hao.ucar.edu/~sgibson/WHI/WHI_Slow_Wind.html)

  JOP 202 is primarily for off-limb streamer observations above closed
  loops/filament cavities. When using the on-disk observing instruments, it
  is part of SOHO Campaign 7266 for Activity in Filament Cavities.

  UVCS will support JOP 202 for the whole duration.

  Apr 3-9       JOP 206/203 Low-latitude Coronal Holes & Coronal Hole Boundary,
                  Campaign #: 7267,
                  UVCS/CELIAS/LASCO/SUMER/CEPAC-EPHIN/
                  ACE-SWICS/Hinode-EIS/Hinode-SOT/Hinode-XRT/
                  STEREO-PLASTIC/STEREO-SECCHI/STEREO-SEPT/TRACE/
                  Ooty/STELAB-IPS/Nancay/NSO-SOLIS/NSO-DST-IBIS
                  POC: Mari Paz Miralles and Craig DeForest,
                  URL: sohowww.nascom.nasa.gov/soc/JOPs/jop206.html


   A low-latitude coronal hole coming around the East limb has been selected
   as the target. Then JOP 206 (The Target of Opportunity 2; see below) will 
   supersede JOP 203.

   UVCS will support JOP 206/203 during April 3 - 17.

  Apr 10-16     JOP 204 Characterizing the energetics and dynamics of
                  the quiet Sun,
                  Campaign #: 7268,
                  CDS/EIT/MDI/SUMER/Hinode-EIS/Hinode-SOT/Hinode-XRT/
                  STEREO-SECCHI/TRACE/HSO-COMP/HSO-MOTH/NSO-IBIS/
                  NSO-SPINOR
                  POC: Scott McIntosh
                  URL: web.hao.ucar.edu/~sgibson/WHI/WHI-QS.html

                  URL: sohowww.nascom.nasa.gov/soc/JOPs/jop206.html

   UVCS will support this JOP when the selected low-latitude coronal hole
   target reaches the West limb during the 3 April - 17 April period.

  ToO-3
  Mar 20-Apr 16 JOP 194 Activity in filaments and filament channels,
                  Campaign #: 7271,
                  CDS/UVCS/EIT/LASCO/TRACE/Hinode-EIS/Hinode-XRT/STEREO/
                  Hinode-SOT/BBSO/ISOON/MLSO/SMEI/ProMag(TBD)/CoMP(TBD)/
                  HELIO(TBD)
                  POC: Therese Kucera, Sarah Gibson
                  URL: web.hao.ucar.edu/~sgibson/CIP21/topcampaign.html

  UVCS will observe at 1.7 solar radii from Sun-center above the selected
  filament cavity at the base of a streamer.  UVCS will participate in this
  JOP between 29 March and 2 April if a suitable target is chosen.

  If a ToO JOP is run, the week's regularly scheduled JOP would also be
  run, but for a reduced time.

  UVCS will support.

  TRACE has received a request to support.

  MDI is supporting with Full Disk, 1 minute cadence Magnetograms/
  Dopplergrams and 96 minute synoptic FD Magnetograms/Continuum Images.

  CDS will participate. As requested, the relevant JOP descriptions have
  been forwarded to the CDS team.

  EIT supports for the WHI JOPs:
  JOP201 Mar 20-26 195A CME Watch
  JOP194 & 202 Mar 27-28, Mar 31-Apr 2 195A CME Watch and the addition of
    FFFres 284A image once per hour at 12 minute mark betweek hours of
    16:00-22:00 UT (this time block may shift to follow prime observation
    times with Hinode as per Kucera/Gibson request).
  JOP203 Apr 3-9 195A CME watch
  JOP204 Apr 10-16 304A CME watch 
  JOP206 Mar 29, 30 195A CME watch

  LASCO will participate with C2pB@ 6 h cadence with C3pB@ 12 h cadence
  along with synoptics; JOP201, JOP202, and Ulysses; unless contacted for
  additional support.

  SUMER will be online from 3 to 16 April. Science operations will start on
  5 April in support of JOPs 203/206 and JOP 204.

  Hinode is currently experiencing technical difficulties that have
  resulted in a reduction in the rate at which scientific data can be
  transmitted to the ground from the on-board recorder. According to the
  Hinode Science Working Group "The problem will have a significant impact
  on how the Hinode mission is operated." For further details see
  http://spd.aas.org/SolarNews/archive/news.html#section1. The WHI
  coordinator has tasked the leaders of individual WHI campaigns
  (JOPs/HOPs) to assess the effect of the Hinode situation on their
  observation plans and revise the plans if needed.

		  POC: Sanjay Gosain

  Target-of-opportunity JOP in conjunction with the JOP 157; primarily for
  May 20-25.


* Jun 11-15     MDI Continuous Contact

  MDI is willing to do high resolution observations during this CC period.
  Specifically, doing another Helioseismology study with Hinode would be
  ideal.  Observing campaigns suggested for HR Helioseismology studies are
  hr_ve_fe_me (620"x310" FOV) or hr_t2_ve_fe_me (420"x420" FOV) in
  non-track mode. Those interested, please request specific observations
  about 1 month ahead of time.  Due to commanding constraints for MDI, we'd
  like to plan our observations ASAP.

  MDI still plans on reserving the June and July 5-day Continuous Contacts
  for HR observations, but no specific requests for collaborations have
  been received.  The default plan for June will be high resolution, 1 min
  cadence filtergrams, dopplergrams and magnetograms.

  To avoid problems with transmitter masks at the end of passes during MDI
  continuous, DSN has requested we bring the carrier down 30 min before the
  end of pass.  As a result, the last 30 min of all MDI continuous contacts
  will be TM only.  For ranging passes, the spacecraft will be transitioned
  to record ~1 h before the end of the pass.  The station will drop the
  carrier and re-sweep into receiver 2.  The spacecraft will then be
  transitioned back to VC2 and VC3.

                  POC: Anna Pietarila

  For details see the JOP 213 description at URL
  http://sohowww.nascom.nasa.gov/soc/JOPs/jop213.txt.

  SUMER will support. See also below "SUMER observing".


* Jun 20-30     SUMER observing

  In addition to supporting JOP 213, SUMER may carry out coordinated
  observations with UVCS.

  The SUMER/Hinode campaign originally scheduled for Apr 2008 is postponed
  until further notice.  The campaign will be structured as multiple JOPs
  in the same fashion as the 2006 SUMER campaigns have been.

  The June 2008 SUMER observation period will be of limited scale and
  scope, not a full-fledged campaign. Some of the JOPs outlined below may
  also be tested during the June observation period, but running them "in
  full" remains TBD.

  Currently submitted JOP/HOP proposals are (timings remain TBD):

  Timing TBD    JOP 207 Eruptive and quiescent prominences Atlas with 
  		  SOHO and Hinode,
                  CDS/SUMER/Hinode-EIS/Hinode-SOT/Hinode-XRT, 
                  POC: Susanna Parenti.
                  Timing TBD.

  Timing TBD    JOP 208 Relationship between movements of magnetic 
  		  features and mass outflow in funnels,

                  POC: Hui Tian.
                  Timing TBD.

  MDI will support JOPs 208 and 209 to as well as it is able depending on
  high rate telemetry availability.

  TRACE had not been contacted for support requests for the original
  campaign timing and asks to be contacted as soon as the new timing is
  being narrowed down.


* Jul 9-13      MDI Continuous Contact

  MDI is willing to do high resolution observations during this CC period.
  Specifically, doing another Helioseismology study with Hinode would be

* Sep 24-28     MDI Continuous Contact

  The default observing sequence will be full disk, 1 min cadence
  Magnetograms and Dopplergrams in addition to our 96 min synoptic
  Magnetograms and Continuum images (when in high rate).

b) Intercalibration activities

  Last Intercal was: Mar 19

* Apr 14-26     ICAL01 (#7113), CDS/EIT/Hinode-EIS/STEREO

  ICALs are normally performed monthly. Below is a SOC proposal for ICAL
  weeks for the next six months.

* May 5-9       ICAL01 (#7113), CDS/EIT/Hinode-EIS/STEREO

* Jun 2-6       ICAL01 (#7113), CDS/EIT/Hinode-EIS/STEREO

* Jun 30-Jul 3  ICAL01 (#7113), CDS/EIT/Hinode-EIS/STEREO

* Aug 4-8       ICAL01 (#7113), CDS/EIT/Hinode-EIS/STEREO

* Sep 1-5       ICAL01 (#7113), CDS/EIT/Hinode-EIS/STEREO

  CDS views Hinode-EIS participation as extremely important.  STEREO-EUVI
  observations might also be used, but ICALs need to be scheduled not to
  coincide with STEREO manoeuvres or other interruptions in observations
  (see http://stereo-ssc.nascom.nasa.gov/plans.shtml). EIS and Stereo have
  been added to the Campaign #7113 description.

  Dates, details and confirmation will be determined by the planners. 

  EIT: ICALs are OK except (usually) during the weeks of shutterless ---
  whenever CDS prefers.



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 in Focus 5 for best focus for FD observing and will stay there at
  least until May 2008.


UVCS:

  UVCS is scheduled to enter Keyhole Safe configuration on 8 May and
  Keyhole Recovery is targeted for 21 - 23 May TBC.

  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.

  LASCO continues the C2 pB program at 6 h cadence till Apr 2008. 
  POC: Angelos Vourlidas.


SUMER:

  Next SUMER observation periods:

  Apr 3-16
  June 20-30
  Nov (timing TBD)

  See section 2a for details.


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.

  TRACE will move back to loading 5 days a week as of the week starting
  3 Mar 2008.

3. Any other business

* Next SPWG:

  Friday May 2 after daily & weekly meetings.

  MDI:    Either date is OK
  UVCS:   Either date is OK


The rest are FYI items:

* Hinode is currently experiencing technical difficulties that have
  resulted in a reduction in the rate at which scientific data can be
  transmitted to the ground from the on-board recorder. According to the
  Hinode Science Working Group "The problem will have a significant impact
  on how the Hinode mission is operated." For further details see
  http://spd.aas.org/SolarNews/archive/news.html#section1.

* In the future SOHO's DSN contacts will grow shorter as we lose 26-m
  antenna support and other, new missions get higher priority. The
  instrument teams are therefore requested to look at the NRT commanding
  that is done (especially for emergencies and recoveries) and see what can
  be converted into TSTOLs that the FOT can run (even without explicit
  instrument or SOC direction).

* MDI high-rate support requests: no change, see URL
  http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html

* DSN support requests: preferably 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: no change, see URL
  http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html

* Hinode operational and planning information and guidelines: no change,
  see URL http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html

* STEREO operational and planning information: no change, see URL
  http://sohowww.nascom.nasa.gov/operations/SPWG/spwg-20080118.html

* 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.

* New JOP vs. modified existing JOP rules-of-thumb: no change, see URL
