<H2>1. Review of action items</H2>

<H2>2. Boundary conditions </H2>

* No maneuvers for the current planning period. 
  Next maneuver will likely be in early October.

* Still no launch date for HESSI. End of September is 
  earliest possibility, if review board gives ok.

* Commanding outlook: See AOB section.
 
* Submodes:  

  Submode 6 until August 20 at 15 UT (TBC)
  Submode 5 until August 31, time TBD
  Then submode 6 until MEDOC Campaign starts (October 15), or
  JOP104 run in October/November, in case HESSI is launched.

* MDI 5-day continuous: August 2-6, and August 29-September 3

* GENESIS launch July 30

* "Vault" launch 25 September: H alpha high resolution high cadence.

* MSSTA III (Montana) launch 1st week in October

* The MDI team is on a track to reduce the MDI shutter usage to half
  or less of present usage, to allow the instrument to be used for
  another 5 or more years. We expect to have a meeting to review
  shutter status and plan long-term operations in a few weeks. We are
  still determining what changes are practical, but one of the things
  being considered is elimination of the nominal 8-hour campaigns as
  much as possible, subject to compelling science arguments. So we
  want to give our colleagues a heads up that MDI may not provide very
  good collaborative support during the late summer and fall, although
  we hope to return to collaborative mode in some reduced level around
  the first of the year.

  In short - if you have projects that require high-cadence MDI support,
  now is a good time to ask!

<H2>3. JOPs status </H2>

New:

 JOP145 Active Region Irradiance Study (#6786), CDS/MDI/EIT/TRACE, 
    07:00-24:00 UT, POC: Eoghan O'Shea (eoshea@so.estec.esa.nl)

MDI will contribute with high cadence magnetograms when possible.
Synoptic program includes only 96 min mags + i-grams when in high
rate (no doppler).

Modified (after meeting):

 JOP118 Temperature Range of the Sunspot 3-minute Oscillations,
   CDS/TRACE/MDI, POC: Olav.Kjeldseth-Moe@astro.uio.no

 Minor change in CDS study lineup (dropping O_SPOT_B).

<H2>4. Priorities for the coming month (W31 - 36, July 30 - September 9)</H2>
a) Joint observing plans and campaigns

Discussed at previous meeting(s):

* Jul 23-Aug 5  JOP145 Active Region Irradiance Study (#6786), CDS/MDI/TRACE, 
                  07:00-24:00 UT, POC: Eoghan O'Shea (eoshea@so.estec.esa.nl)

New:

* Aug 6-19      JOP118 Temperature Range of Sunspot 3-minute Oscillations,
                  CDS/TRACE/MDI(TBC), POC: Olav.Kjeldseth-Moe@astro.uio.no,
                  Terje Fredvik (local). 2-3 days continuous run on spots
                  crossing meridian, and 10-14h runs on other spots.

TRACE Aug 10-19 originally - most likely will participate all the time.
MDI still TBD, but will likely support with 1 min cadence (when possible).

* Aug 19-25     CDS/BBSO Quiet Sun Study, POC: Louise Harra, 15:30-01:00 UT.

Start may be delayed due to JOP118.

See monthly calendar at: 
  http://sohowww.nascom.nasa.gov/soc/head_calendar.html

The MMOP011 Sigmoidal active region study has been revived by the
Max Millennium group (until HESSI launch).

b) Individual instrument plans

CDS:

CDS will have one full day of CME watch per month (July & August).

* Aug 27-Sep 9  CDS Extended Coronal Effects of Flares (TBC),
                  POC: Carl Foley (caf@mssl.ucl.ac.uk)

* Week of Aug 20 CDS Raw dumps - note about NRT.

UVCS:

* Jul 30-Aug 12 UVCS CME watch/JOP136, POC: Kuen Ko
* Aug 13-Sep 2  UVCS Polar Streamer and Coronal Mass Ejection Observations
* Aug 20-25     UVCS Alpha Leo observations
* Aug 27-31     UVCS Rho Leo observations

SUMER:

* Aug 21,30     SUMER observations by Spiros Patsourakos (details TBD).

* Aug 22-23     SUMER Alpha Leo Observations
* Aug 23-30     SUMER The Sun as a star - observing scattered light.
* Aug 29-30     SUMER Rho Leo Observations

EIT's next shutterless will most likely be in September (first week
seems promising for NRT).

c) Intercalibration activities

Week 32/33      Intercal 1 (TBC), CDS/EIT, POC: EIT planner

<H2>5. Preview of future months</H2>
* See the Monthly Calendar at: 
  http://sohowww.nascom.nasa.gov/soc/head_calendar.html

<H2>6. AOB</H2>
* Next SPWG: Friday 24 August.

* NOTE: September SPWG: Friday 28 September.

* DSN support should be requested at least 6 months in advance.  Keep
  this in mind for: ground-based collaborations that require MDI
  support, stellar observations that require NRT, etc.

* Commanding outlook

These times are subject to change. More details are available if wanted

Week 30 - July 23: DSS27 most of the week. Saturday is good.

Week 31 - July 30: First part of the week is on DSS27. Friday is
                   a good day for commanding.

Week 32 - Aug 06:  DSS27 on Monday and Tuesday. There are gaps in
                   the early afternoon most days, so command late.

Week 33 - Aug 13:  DSS27 on Monday and part of Tuesday. There are 
                   gaps in the early afternoon most days, so 
                   command late.

Week 34 - Aug 20:  DSS27 on Monday afternoon. There are gaps in the
                   early afternoon most days, so command late.

Week 35 - Aug 27:  DSS27 on Monday afternoon. Rest of the week is good.

Week 36 - Sep 03:  Good week for commanding except for a couple of
                   early afternoon gaps.
