SPWG Minutes Friday, February 16, 2001

1. Review of action items


2. Boundary conditions

* No maneuvers planned in March and continuous contact all month. Continuous starts 28 Feb - end of May. The first month is best effort. First two months Full Disk in best focus. If 60 days of good full disk data has already been achieved, first 2 weeks of May will be in HR (hr_v1_m2). Second half of May: Full disk and high res doppler (only), no high cadence magnetograms. There will be gaps in the continuous due to non-overlapping stations. Modifications to the solid state recorder operations will be discussed to minimize impact to MDI high rate telemetry. Next maneuver not until May 31. * Submodes: Submode 5 from February 26 until March 26

3. JOPs status

New: MMOP003 Regions likely to produce major flares This will be called only when it is deemed likely that a major gamma-line flare will occur. See Any Other Business for more HESSI information. JOP138 Decimetric storms and Decametric type III bursts POC: Lidia van Driel-Gesztelyi VLA/EIT/Yohkoh EIT will do 171A CME Watch (not subfields) Updated: JOP122 Micro-scale heating blocks of the solar atmosphere, SUMER/CDS/TRACE, POC: J.G. Doyle, Werner Curdt (EOF) (No VLA/EIT/Yohkoh/MDI component, modified CDS rasters)

4. Priorities for the coming month (W09-W12, Feb 26-Mar 25)

a) Joint observing plans From previous meeting(s): * Dec 8-Feb 28 MMOP011 JOP106 Sigmoidal Active Region Study (#6670) CDS/EIT/MDI/UVCS/TRACE/Yohkoh-SXT/et al. POC: Sarah Gibson (sgibson@solar.stanford.edu) EOF: Andrzej Fludra (fludra@cdso8.nascom.nasa.gov) * Feb 1-Mar 28 JOP136 Default HESSI Collaboration (test run of MMOP009) (#6697), POC: Richard Canfield * Feb 27-Mar 12 JOP137 Time Variation and Dynamics of Active Region Loops II (#6695), TRACE/CDS/SUMER, EOF: Terje Fredvik POC: Olav Kjeldseth-Moe (olav.kjeldseth-moe@astro.uio.no) (2-week uninterrupted loops campaign). New: * Feb 24,25 Quiet Sun Transient Events Study, Mar 28,29 CDS/SUMER/EIT/MDI/TRACE/YOKOH-SXT, POC: Clare Parnell EOF: Andrzej Fludra Note: March dates will most likely be CDS/TRACE only. * Feb 26 JOP122 Micro-scale heating blocks of the solar atmosphere, SUMER/CDS/TRACE, POC: J.G. Doyle, Werner Curdt (EOF) 4-hour run on same pointing as Intercal 1 * Mar 2,4,5,8 JOP138 Decimetric storms and Decametric type III bursts submitted by Lidia van Driel-Gesztelyi VLA/EIT/Yohkoh/VLA TRACE may support: 15-19 UT MDI will be in continuous contact with 1minute full-disk magnetograms and dopplergrams. b) Individual instrument plans CDS: * Week 12 CDS planning will be done from RAL EIT: Will run shutterless operations a few hours at a time, time TBD. Repeats may be expected roughly every two months. See also the monthly calendar c) Intercalibration activities Feb 26 ICAL001 SUMER/EIT/CDS, 19 UT, POC: Werner Curdt

5. Preview of future months

* See the Monthly Calendar at: http://sohowww.nascom.nasa.gov/soc/head_calendar.html

6. AOB

* Brian Dennis gave an update on HESSI: Launch will be delayed because of a problem with the Pegasus launcher (1 day per day until problem is solved). HESSI expects to be operiational about 1 week after launch, and the mission duration is nominally 3 years (although HESSI has no consumables). A discussion on HESSI science goals and SOHO/TRACE support observations concluded that a contingency plan should be put in place to ensure rapid notification of SOHO and TRACE planners whenever MMOP003 (Regions likely to produce major flares) is is called. Observational details may be similar to JOP136, but a switch to Submode 6 would be desirable from HESSI's point of view. * Next SPWG: March 16, 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.
