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


<H2>2. Boundary conditions </H2>
* No maneuvers planned in April and continuous contact all month.

  There will be gaps in the continuous due to non-overlapping stations.

  First two months Full Disk in best focus. If DSN coverage continues to be
  good, first 2 weeks of May will be in high resolution (hr_v1_m2). Second
  half of May: Full disk and high res doppler (only), no high cadence
  magnetograms.

  MDI's flatfield results from the offpoint have been useful, and MDI would
  participate in repeat performances.

  [NOTE - changed after meeting:]
  The maneuver that was scheduled for May 31 will likely be postponed. 
  Suggested date is June 28.

* NOTE: POLAR maneuver with hot DSN backup scheduled for week 13 
        (March 26-April 1). Impacts to DSN support for SOHO TBD.

* HESSI launch/planning update
  No earlier than May 15. 

* Submodes:  

  Submode 5 until March 26
  Submode 6 until May 14
  Submode 5 until May 31 (TBC)
 
<H2>3. JOPs status </H2>
New:

JOP139 A study of helium abundance from coordinated Sac Peak-SOHO-Ulysses 
       observations, UVCS/CDS/EIT/CELIAS(SEM)/SUMER/LASCO, 
       POC: Giannina Poletto

No remarks.

JOP140 Origin of Type I radio noise storms, 
       CDS/MDI/EIT/TRACE/Yohkoh/VLA/Nancay, POC: Lidia van Driel-Gesztelyi

It would be nice if MDI requirements were specified. For the time period in
question, MDI will give 1 minute cadence full disk cropped magnetograms and
dopplergrams. Also, EIT will do 195 Angstrom CME watch, not 171 subfields.


JOP141 Emission lines in Near-Sun Comets, LASCO/UVCS/Arecibo, 
       POC: Doug Biesecker

No remarks.

<H2>4. Priorities for the coming month (W13-W17, March 26-April 29)</H2>
a) Joint observing plans

From previous meeting(s):

* Feb  1-Mar 28 JOP136 Default HESSI Collaboration (test run of MMOP009)
                  (#6697), POC: Richard Canfield

New:

* Mar 18-May 15 JOP106 (MMOP011) Sigmoidal Active Region Study (#6721),
                  CDS/EIT/UVCS/MDI/TRACE/Yohkoh-SXT/et al.
                  POC: Sarah Gibson (sgibson@solar.stanford.edu)
                  EOF: Stein Haugan, Prime time 1700-2300 UT

Note: MDI will most likely be in HiRes first 2 weeks of May

* Mar 18,23,24  JOP140 (MMOP012) Origin of Type I Radio Noise Storms (#6716), 
                  VLA/CDS/EIT/TRACE/MDI/Yohkoh-SXT,
                  POC: Lidia van Driel (Lidia.vanDriel@obspm.fr),
                  RAL: Barbara Bromage/Keith Macpherson

EIT will do 195 Angstrom CME watch

* Mar 28,29     Quiet Sun Transient Events Study (#6717),CDS/TRACE/EIT/Yohkoh,
                  POC: Clare Parnell EOF: Andrzej Fludra

EIT shutterless operations in 195 Angstrom *TBC*.

Moved (delayed until August):

* August        JOP104 Doppler Shifts in X-ray Jets, 
                  SUMER/CDS/EIT/UVCS/TRACE/HESSI/Yohkoh/MICA/HASTA, 
                  POC: Davina Innes

b) Individual instrument plans

See monthly calendar.

TRACE target of opportunity for April 3-27: Loop oscillations 195 Angstrom

c) Intercalibration activities

* Week  14      Intercal 1, CDS/EIT, POC: Frederic Auchere

TRACE participation TBD.

<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: *TUESDAY* April 24, 2001 at 2:00 pm in EAF

* REMINDER:  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.
