1. Review of action items
2. Boundary conditions for the coming month
- MDI Continuous: May 1, 9:00 UT - May 7, 21:30 UT
- Submode 3: Still under investigation by LASCO/EIT team.
- TRACE 30 day plan
Plans being revised daily.
During MDI continuous, running a 3-day quiet sun movie.
After May 6, TRACE will perform more limb pointings.
In late May/early June, they want to pick an active region on the
East limb and follow it for 2 weeks.
- May 31: 6 Hours SVM reserved for Memory Dumps and TR Maintenance
3. Preview of future months
- Third Medoc Campaign
General consensus is that is would not be wise to have a
MEDOC campaign due to effort involved in TRACE coordination.
Everyone would welcome SUMER observing from MEDOC and ground
based campaigns. But wants the coordination and daily meetings
to be in the EOF. TRACE representative present at SPWG
opposes the MEDOC campaign and will have a representative at
the SWT indicate such. UVCS indicated that during that time
frame some of their observations include already fixed stellar
Also indicated that more advance notice is needed for these
- S/C activity plans for June or, including roll and offset
Unchanged. EIT notes that the data from the ESR actually helped
them with their flat-fielding problems !! HOWEVER, they still
would like to do an offset -- but the urgency is not so great.
They would yield if other experiments strongly object.
- Second Whole Sun Month
Sarah Gibson and Doug Biesecker are continuing preparations.

4. Priorities for the coming month
a) Individual instrument plans
UVCS -- 4-20 May:
Shadia Habbal, Coordinated observations with Mars Global Surveyor.
21 - 24 May:
G. Poletto will perform coronal hole measurements
25 - 31 May:
Joe Michels, performs instrument characterization.
LASCO -- Not much planned. C1 characterization.
EIT -- JOP080 (shutterless mode). TRACE support.
MDI -- Plans are generally to support TRACE and SUMER.
Flare watch is suspended, have not instituted.
During last week of May and first week of June, they are
keeping their planning simple due to stafffing constraints.
CDS -- Most of their primary goals are already listed in JOPs on
WWW calendar. Active region monitoring campaign.
b) Intercalibration activities
ICAL01 TBD. UVCS will discuss if they want to run this the week
SUMER is on. Andrzej Fludra will inform CDS and check with SUMER
to see if SUMER has a desire to run ICAL01.
c) Joint observing plans
- Submode Schedule
During SPWG, CDS and EIT asked for a scientific case for why Submode 4
is necessary. CDS and LASCO/EIT would much rather not sacrifice their
telemetry for 30+ hours, and continue collaborating with the TRACE 30
day program. TRACE would commit to this observation if other experiments
(LASCO/EIT and CDS) sacrifice.
After the SPWG, SOC to e-mail Phil Judge regarding JOP072. Phil Judge
replied saying Submode #4 is essential. CDS agrees now with submode 4.
- Penciled in JOP080 into the calendar the week that SUMER is ON.
(Week 20). Only one hour program.
5. JOPs status
SOC is completing of Campaign Catalog for Primary Mission. Every campaign
that has been run is listed. Names, dates, participants, and coordinator
fields are nearly complete. Format has been homogenized. However, no
objectives are listed for many campaigns (they are all listed for JOPs
and ICALs). Piet Martens will contact campaign leaders by e-mail to fill
6. New JOPs
- JOP081, Solar Magnetic Fields, Sarah Gibson, Proposed for WSM2
Write-up was not appropriate for JOP. Will re-write and submit again.
- JOP082, Flux Disappearance in Dipoles, Karen Harvey, proposed
for June 12-30.
Unlikely SOHO will be able to support all of this time due to maneuvers.
But there is a great willingness to support first part: June 12-22.
- JOP083, HIGH CADENCE ACTIVITY STUDIES AND THE HEATING OF CORONAL
LOOPS, Robert Walsh, proposed for May? Conflict with JOP072?
Tabled. Ted Tarbell will talk to Robert Walsh next week about this.
- Next SPWG Friday May 22 (4th Friday!)
