SPWG Minutes Friday, February 22, 2002

1. Review of action items

Closed: J. Khan/T. Kucera: Submit JOP description for "Multi-wavelength Observations of Large-scale Shock Waves on the Sun" New: SUMER/MDI/UVCS/CDS/LASCO/EIT: Review description of observational sequence(s) for Major Flare Watch (JOP153/MMOP003).

2. Boundary conditions

* No maneuvers are scheduled for the current planning period. Note that there is a *very* small chance that a maneuver must be held in the two weeks after the scheduled TDRS launch (8 March), to enable at least 60 days of MDI continuous. * HESSI is fully operational. See note under Section 3. * The X-panel heater changes appear to have given ERNE a relief of about 1 degree C. * MDI "continuous" observations resumed on or about February 14, but will be impacted by TDRS launch. * TRACE has ended eclipse season and switched to 195 A. * No news from Yohkoh. * MSSTA-III EUV rocket launch has a tentative date: April 10, 2002 (TRACE) * VAULT launch (JOP148) has been postponed. Most likely end of April or early May. * Submodes: Submode 6 for the current planning period, but: SUMER plans to be turned back on April 5, doing some engineering before a JOP104+JOP137 run starting April 8, 9, or 10, lasting until May 20 (JOP137 ends April 20), followed by: MEDOC #9 May 20-Jun 2. Note that if a Major Flare Alert occurs in Submode 5, and SUMER is not doing Major Flare Watch-relevant observations, submode switches must be negotiated. * Commanding outlook: See AOB section. * EIT CalRoc launch shooting for the mid-August, 2002. Would like to have a repeated offpoint maneuver close in time. * CELIAS/SEM underflight rocket to be launched at the same time as the EIT CalRoc. * The MDI team is on a track to reduce the MDI shutter usage to half or less of present usage. See full message under AOB. In short - if you have projects that require high-cadence MDI support, now is a good time to ask, and make sure to make specific requests if you need MDI data.

3. JOPs status

No new JOPs at the time of the meeting. Since we didn't have a pointer to the Max Millennium Observing Plan for Major Flare Watches (MMOP003) from our JOP pages, we've created a new JOP (after the meeting), based on the latest input from instrumenters. MMOP003 was accepted on par with a JOP at the February 2001 SPWG meeting as the response to a Major Flare Watch, and was later mentioned in SPWGs on April 24, May 25, and June 15, 2001. It was also discussed at the April 2001 SWT. JOP153 Major Flare Watch/MMOP003 Region Likely to Produce Major Flares CDS/EIT/LASCO/SUMER/MDI/UVCS/TRACE/HESSI/MaxMillennium Please review your instrument's contribution to the Max Millennium observing program, and report changes either to the SOCs or directly to Dick Canfield (canfield@mithra.physics.montana.edu). Another JOP has arrived since the meeting (please review for next month's meeting): JOP154 Joint SOHO-GBO Campaign to Study Chromospheric and Photospheric Network MDI/SST/DOT/TRACE, POC: J.M.Krijger

4. Priorities for the coming month (W10 - W13, March 4 - 31)

a) Joint observing plans and campaigns * Mar 12-25 JOP118 Sunspot Oscillations, CDS/TRACE, 10.5 hours per day, POC: Olav Kjeldseth-Moe, Terje Fredvik (TBC) Target of opportunity: * JOP136/MMOP009 Default HESSI collaboration * JOP153/MMOP003 Major Flare Alert b) Individual instrument plans UVCS * Mar 30-Apr 2 UVCS HESSI Campaign Floating Days Note: This activity will be moved to whenever a Major Flare Watch occurs. See also SOHO monthly calendar for weekly plans CDS See their request diary for details (http://solg2.bnsc.rl.ac.uk/scientificops/request.shtml) MDI: Default plan is full disk (continuous contact). TRACE: Eclipse season until mid-February. Expect simple plans, following active regions. Currently in 171 Angstrom. LASCO/EIT: No special plans c) Intercalibration activities * Week 11/12/13 Intercal 1, CDS/EIT, POC: Terje Fredvik/TBD

5. Preview of future months

6. AOB

* Next SPWG: Friday March 22, 2pm * NOTE April SPWG: Friday, April 19, 2pm * 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! Also, if you need MDI data, make sure you request it specifically. * 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 available if wanted: Week 10 - Mar 04-10: D27 most of the day on Thursday, Saturday, and Sunday. D27 in the afternoons on Monday, Tuesday, Wednesday. Friday is good. Week 11 - Mar 11-17: D27 most of Tuesday. D27 in the afternoons on Monday, Saturday, Sunday. Wednesday is good. Thursday D27 is from 17-19:30 UT. Friday has a D/L only station from 18-23 UT. Week 12 - Mar 18-24: D/L only after 18 UT on Monday. D27 most of the day on Tuesday and Sunday. D27 in the afternoons of Wednesday and Thursday. D/L only from 15-18 UT on Friday. D/L only then D27 in the afternoon on Saturday. Week 13 - Mar 25-31: D27 most of the day on Tuesday and Sunday. D27 in the afternoons on Monday and Thursday. Wednesday is good. D27 from 15-19 UT on Friday. D/L only after 18 UT on Saturday.
