  means of communication, etc) for the future. To be discussed at the
  next SPWG.

  Safing and recovery on adjacent days (Oct 9 & 11).

* No MDI continuous contact in October

* Oct 14        Columbus Day (Holiday in US)

* Oct 19        GSFC network upgrade, outage 14 UT - 20 UT (10am-6pm local)

* Oct 27        US & European Daylight savings ends, GSFC local = UT - 5h

* Submodes:

  Submode 6 until October 21, 13 UT, then...
  Submode 5 until November 1, 15 UT, then...
  Submode 6 for the foreseeable future (SUMER mini-campaign March/April 2003)
  NOTE: Luca Teriaca has asked for SUMER support Nov 16 - Dec 3 (TBC)

* MEDOC Campaign #10 is planned for October 21 - November 3

* Commanding outlook: See AOB section.

3. Priorities for the coming month (W41-44; October 6 - November 3)

a) Joint observing plans and campaigns

* Mar/Apr 2003  JOP161 Comprehensive Footpoint Study, 
                  SUMER/CDS/EIT/MDI/TRACE, POC: Scott McIntosh

CDS, EIT, TRACE, MDI agree to a test run (time TBD - early in 2003). 
MDI High Rate may be requested for the real campaign.
Some details in the JOP will be filled in, e.g:
EIT & CDS will most likely run Intercal 1 program.

* Oct 12,14,17  JOP100 Active Region DEM for Heating & Magnetography Studies,
                  CDS/EIT/VLA/MDI/TRACE, ~16:30-21:30 UT, POC: Jeff Brosius

TRACE program must be specified (one EUV filter)

MEDOC Campaign:

* Oct 21-27     JOP157 Bright Points in AR, CDS/EIT/MDI/TRACE/RHESSI, 
		  8-18 UT, POC: Brigitte Schmieder

                JOP158 The Fast Solar Wind from 1.05 to 4 Ro,
                  CDS/UVCS/SUMER/EIT/LASCO, 18-24 UT daily,
                  POC: Alan Gabriel & Ester Antonucci

		JOP131 Spectro-polarimetric Diagnostics of Prominences and
		  Filaments, CDS/SUMER/TRACE/THEMIS, 
		  POC: Brigitte Schmieder

The observational details (most instruments!) need to be specified for
JOPs 157 & 131.

Note: Some TRACE absorption starts Oct 13.

* Oct 28-Nov 3  JOP112 Coordinated SOHO-Ulysses Elemental Abundance Study,
		  CDS/LASCO/SUMER/UVCS, POC: Susanna Parenti & Giannina Poletto
                   
Note: SUMER closes door on Oct 31.

Continuing campaigns:

*               JOP159 CME's in Lyman-alpha (#6870), SWAN/LASCO/EIT/UVCS(*),
                  POC: Chris St Cyr, Eric Quemerais

Targets of opportunity for the whole period:

*               JOP136/MMOP009 Default RHESSI collaboration (#6850)
*               JOP153/MMOP003 Major Flare Alert

Campaign number 6850 has been set aside for "individual instrument studies"
that select their AR target [partially] influenced by the RHESSI target. Note
that the RHESSI target will be observed by a significant number of ground
based observatories, so chances for serendipitous co-observations are larger
when selecting the RHESSI target.

NOTE: MaxMillennium targets are valid from the time it is announced
until a the next announcement (not *really* for a set 24-hour UT
interval). However, all we can do is interpret it as the "most likely
target for tomorrow's UT day".

NOTE: None of the SOHO SWT members objected to a continuation of the
current regime of Major Flare Watch participation. The alert system
will be left in place; ANOTHER REVIEW WILL BE MADE AFTER 3 MORE
CALLS. Note that each instrument is free to modify their response by
contacting SOCs and/or Dick Canfield for relevant changes to
JOP153/MMOP003 descriptions.

TRACE will consider changing it's level of support for future Major
Flare Watches.

NOTE: We will generate campaign numbers in advance for Major Flare Watches
(JOP153) as well. The NEXT Major Flare Watch campaign no. is: 6892

b) Intercalibration activities

Last Intercal 1: September 18

* Week 42   Intercal 1 (TBC), CDS/EIT, POC: CDS/EIT Planners

c) Individual instrument plans

(See the SOHO monthly calendar for weekly plans)

CDS:
  See their request diary for details
    (http://solg2.bnsc.rl.ac.uk/scientificops/request.shtml)

LASCO/EIT:

  Oct 9 or 23   EIT Shutterless

UVCS:

  Oct 16        UVCS Star Observations

TRACE:

  Interested in collaborating with UVCS on polar coronal hole observations

4. AOB

* Next SPWG: Friday 25 October at 2pm in the EAF

* 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.

* If anyone has projects that require high-cadence MDI support,
  now is a good time to ask! If you need MDI data, make sure you request
  it specifically.

* Commanding outlook
