               $Author: tsiili $
               $Revision: 1.10 $
Change log is at the end of the document.

1. Boundary conditions

a) Orbit, attitude and manoeuvres

- SOHO is in upside down roll (180 deg) position

- manoeuvres

  Aug 30        stationkeeping and momentum management
  Aug 31        roll

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


b) Communications with the spacecraft

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

* 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

* 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 dependent activities/submode changes:

* TOO           JOP153/MMOP003 Future Major Flare Watch (SM5 if SUMER
                observes target, SM6 otherwise)
* Oct 24-29     SUMER campaign preparations (SM5, timing TBC)
* Oct 30        EUNIS Sounding Rocket Launch, 18:00 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)
* Nov 8,14 TBD  EIT shutterless #29 (timing TBC) - dates will change

- 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.

  During the Aug 2007 keyhole EIT will bakeout Aug 26-Sep 1.


e) Others

  Hinode eclipse season 7 May - 10 Aug.

  TRACE winter eclipse season is 13 Sep 2007 - 13 Mar 2008


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. 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.


* Aug 3-31      JOP189 Microflares and Network Dynamics (#7240),
                  CDS/EIT/MDI/TRACE/Hinode-EIS/Hinode-SOT/Hinode-XRT/
                  RHESSI/DOT/KSO, POC: Jan Rybak, Peter Gomory, 
                  Local POC: Tero Siili, Alex Young

  MDI supports JOP189 when we have high rate data.


* MDI 60 Day continuous contact has been changed to Dec 3-Feb 3


* Oct 21-Nov 16 JOP190/HOP027 Temperature, Density and 3-D Structure of
      	          AR Loops, CDS/SUMER/MDI/Hinode-EIS/Hinode-SOT/
                  Hinode-XRT (TBD)/ TRACE (TBD)/STEREO/VTT/Huairou,
                  POC: Davina Innes

  Note: this JOP run is associated with the SUMER campaign beginning on Nov
  2.  Due to ground-based observatory supports the run begins already on
  Oct 21.

  CDS will support.

  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.

  MDI received a request for observations for a joint Hinode/MDI
  high-resolution campaign.  However, the dates are not firm, but were
  tentatively planned for 01-15 Nov to avoid the SUMER/Hinode campaign.
  Now that the dates have changed, this may cause a problem.  MDI is
  waiting to hear from Takashi Sekii on whether or not we will change the
  dates.


* Oct 21-Nov 16 JOP191/HOP027 3-D Structure and Evolution of Filaments/
      	     	  Prominences, CDS/SUMER/MDI/Hinode-EIS (TBD)/Hinode-SOT/
                  Hinode-XRT (TBD)/ TRACE (TBD)/STEREO/VTT/Huairou,
                  POC: Davina Innes

  Note: this JOP run is associated with the SUMER campaign beginning on Nov
  2.  Due to ground-based observatory supports the run begins already on
  Oct 21.

  CDS will support.

  Since the 60 Day CC is moved, MDI can provide either FD or HR mode
  observations. See also response to JOP190 above.


* Oct 21-Nov 16 JOP192/HOP027 Chromospheric Heating - Signatures of
                  Waves and Reconnection, CDS/SUMER/MDI/Hinode-EIS (TBD)/
                  Hinode-SOT/Hinode-XRT (TBD)/TRACE (TBD)/STEREO
                  POC: Davina Innes

  Note: this JOP run is associated with the SUMER campaign beginning on Nov
  2.  Due to ground-based observatory supports the run begins already on
  Oct 21.

  CDS will support.

  Since the 60 Day CC is moved, MDI can provide either FD or HR mode
  observations. See also response to JOP190 above.


* Oct 24-29     SUMER campaign preparations (timing TBC)


* Oct 30        EUNIS Sounding Rocket Launch, 18:00 UT,
                  CDS/MDI/SUMER/EIT (all TBC), POC: Jeff Brosius, 
                  Douglas Rabin, Andrew Thomas
  
  CDS will support, need more details.

  Jeff Brosius had inquired about the possibility of MDI being in high-rate
  during the flight, which would require a backup DSN station. Backup DSN
  coverage request has been submitted to the scheduler, but availability
  information is not yet available. That time frame is, however,
  contentious due to Phoenix, Dawn and Selene. If a backup station turns
  out not to be available, we need to find out if SOHO will need to be in
  record and if that will be OK with the EUNIS people (in that case MDI
  will not get high rate data other than 96 minute Synoptic Magnetograms).

  From D. Rabin: Key timing goals are coincidence with Hinode observations
  and proximity (slighly before) local noon. The launch time is flexible
  approximately within 1700-2000 UTC to accommodate DSN availability. More
  detailed information on the launch time is forthcoming. Flight duration
  is approx. 10 min. Launch schedule solidifies in early October, but the
  launch may be delayed on about a week's notice. A likely backup launch
  date would be 2-3 days after the baseline date.


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

  Note that these dates have changed. JOP leaders are being contacted
  to see what they will change their dates to be.

  Submode change and SUMER door opening will be on Oct 26 or Oct 29, TBD.

  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, some of which begin
  already before this time frame due to ground-based observatory
  supports. 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.

  POC in ISAS:           Enrico Landi (TBC)
  POC in MPS:            Davina Innes
  SUMER planner in GSFC: Udo Schuehle

  MDI apparently has not gotten a formal request for this.  See above
  comment about a possible collaboration between MDI and Hinode 1-15 Nov
  that may now conflict with the SUMER/Hinode studies including this Polar
  Plume Study.

  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      JOP193/HOP031 Coronal Holes Boundaries Evolution, CDS/SUMER/
      	     	  MDI/Hinode-EIS/Hinode-SOT/Hinode-XRT/TRACE/STEREO/VTT, 
                  POC: Maria Madjarska

  CDS will support.

  Since the 60 Day CC is moved, MDI can provide either FD or HR mode
  observations.  See also response to JOP190 above.

  Dates of this JOP were specified on Nov 23. That information has been
  e-mailed to instrument planners.

  TRACE had this running from 22 Oct - 2 Nov with specifics to be
  defined. Again this was with the original SUMER campaign timeframe.


* Nov TBD       HOP032 Magnetic Structure of Macrospicules, SUMER, 
                  POC: Gerry Doyle

  The POC has been e-mailed to request clarification on the dates and the
  SOHO/TRACE supports desired.


* Nov 6-17      Characterization of Fast and Slow Solar Wind Source 
                  Regions, SUMER/UVCS/Hinode-EIS, POC: Enrico Landi, 
                  Mari Paz Miralles 

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

  The POC has been e-mailed to request clarification on the dates and the
  SOHO/TRACE supports desired.


* Oct 30-Nov 5  Polar Plumes, UVCS/SUMER/CDS/Hinode. POC: Giulio Del Zanna

  A Hinode HOP (entitled "Multi-wavelength observation of coronal hole
  plumes at solar minimum") has been proposed by Giulio Del Zanna asking an
  observing period 30 Oct - 4 Nov.

  MDI hasn't gotten a request for this.  Maybe they don't need MDI support?
  Is this part of the other polar plume and AR study that will happen 2-16
  Nov?

  The POC has been e-mailed to request clarification on the dates and the
  SOHO/TRACE supports desired.


* Nov TBD       HOP003/Velocity Field in a Coronal Hole HOP003 Study #32,
                  SUMER, POC: Suguru Kamio

  Re-run.

  The POC has been e-mailed to request clarification on the dates and the
  SOHO/TRACE supports desired.


* Nov 8, 14 TBD EIT shutterless #29 - dates will change


* 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 Full Disk Magnetograms and
  Dopplergrams (p30vr_fd_m1 - 1100).  We will not switch to high-rate
  during this time.


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


b) Intercalibration activities


  Last Intercal 1: 10 August 2007


* Sep 10-14    ICAL01 (#7113), CDS/EIT, TBC

  Possible EIS collaboration. 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.


SUMER:

  Nov 2-16      Polar plume and active region morphology studies,
                  SUMER/CDS/MDI/UVCS/EIT/VTT/HINODE (TBC)/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.


* .REL files' creation interval

  To aid getting prompt relativistic electron information from COSTEP with
  which to predict solar energetic particle (SEP) events, we are wondering
  if all instrument teams can support changing the creation interval for
  .REL files to 1 minute instead of 30 minutes? This would not affect
  real-time telemetry streams, only the .REL files that are currently ftp'd
  to you every 30 minutes.

  Status: based on e-mail inquiry responses, this approach seems to be too
  much effort to too many groups. COSTEP will investigate using their
  realtime data stream instead. EIT team has agreed to provide assistance
  in implementation and testing.


* Next SPWG:

  Friday 28 September 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/

* 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.
