station keeping maneuver just prior to 2 months continuous.

- SPWG 3.4:
- on PIs to start providing summary data routinely in April.
- SPWG 3.5:
- on PIs to routinely provide input to "as-run" database in April.

Each instrument team representative gave a brief report of their
activities and achievements of the past month.

3. Long-term schedule: plans for 2 months continuous
Action on PIs to provide plans for 2 months continuous at next SWT meeting.
4. JOPs status and priorities
- Need for sty-file on WWW Jop page to instruct authors
of future submissions.
- Need to convert all Tex and LaTex file to HTML format
(use converter)
- Reviewed status of high priority JOPs for May timeframe.
- Priority JOPs for April dry-runs: JOPs 002, 013, 035.
5. New JOPs
No new JOPs were proposed.
6. Final commissioning report
Final experiment commissioning report is intended for
presentation to ESA D/Sci and ESA SOHO Project. There
will be similar reports on Spacecraft and ground system.
No objections against proposed format. Project Scientist
will distribute outline early next week via e-mail.
PI's to supply requested information ultimately April 6.
This is a purely formal report, no need for images,
or other science highlights.
FINAL REPORT ON SOHO COMMISSIONING (page 1)
- Originates from SOHO Project Scientist, with contribution
from all SOHO PI Teams
- To be submitted at the time of the SOHO handover from
ESA Projects to SSD (April 16). If not in final form, at
least a complete draft.
- Draft presented to SPWG, and if agreed, outline will be
send to PI's by e-mail
We propose a fairly strict uniform report format to achieve the following:
- Possibility of a clear comparison between experiments, and
with the pre-launch commissioning plan
- Avoidance of lengthy descriptions
- Minimal effort by PI teams: much of the report will
simply consist of checking boxes.
- Reports easy to summarize by Project Scientist Team
Presented here is a draft for the reports' contents, and an example
of an outline for one experiment (GOLF). The draft of the
cleanliness part is based on a fax from Ron Thomas and Peter Jensen.

FINAL REPORT ON SOHO COMMISSIONING (page 3)
EXAMPLE: GOLF
(Note that the following outline report would be e-mailed to the
PI for completion. Also note that for some experiments, not just
the blocks, but also the sub-blocks would be included, as they
contain noteworthy information)

Page 5: Cleanliness report:
(1) first exposure to space/sunlight,
(2) number of hours of operation, fully exposed to space/sunlight,
(3) observations of any trends in performance,
(4) observations of any temperature drifting of sensor optics,
(5) observations of any particle contamination,
(6) comments from PI
END-OF-DRAFT
7. Plans for vacating EOF overflow room (SWAN, CELIAS, CEPAC, GOLF)
Small experiments would like to continue using EOF
overflow room. A quick survey demonstrated that there
is insufficient space in the EOF. It was decided to try
to rearrange IWS's to give the room a dual purpose --
meeting room, and overflow room (as it was used prior
to launch). Thus FOT may support us in keeping the room
for SOHO use.
8. Summary Data and "As-run-database"
Action item on experiments: to start providing summary
data routinely in April. It was also agreed that each
experiment should produce their "as-run" database from
their science plans, with at most several days delay.
Action item on experiments to routinely provide input
to "as-run" database in April.
