SOHO WEEKLY MEETING MINUTES Week 13, March 26 - April 1, 2001 1. Announcements ---------------- * No submode change on Monday - SUMER would like to continue observing an additional 2-3 weeks to observe some interesting active regions that are appearing on the disk at this time (AR 9390 and the as yet unnumbered complex trailing it). They will do refspecs on the west limb until the regions come into their view. Planners for other teams see no problem with this extension for SUMER. 2. Operations Constraints ------------------------- * Due to an interesting active region complex coming around, SUMER has decided to continue observing 2-3 weeks. This allows time for the region to get to the west limb. * DSN schedule - 9 downlink only stations for week 13 Wednesday - best commanding is on DSS-16 after 20:30 UT 3. Coordinated Observations --------------------------- M Mar 26 (W 13) T Mar 27 CDS 24-hour Uninterrupted CME Onset Watch W Mar 28 Quiet Sun Transient Events Study (#6717), CDS/TRACE/Yohkoh, POC: Clare Parnell EOF: Andrzej Fludra T Mar 29 Quiet Sun Transient Events Study (#6717), CDS/TRACE/Yohkoh, POC: Clare Parnell EOF: Andrzej Fludra F Mar 30 S Mar 31 S Apr 01 Other activities for Week 13: * NOTE: POLAR maneuver with hot DSN backup scheduled for this week.

POC: Sarah Gibson (sgibson@solar.stanford.edu) EOF: Stein Haugan, Prime time 1700-2300 UT Submodes: Submode 5 all week Planners for Week 13: CDS -- Andrzej Fludra MDI -- Sarah Gregory EIT -- TBD SUMER -- Enrico Landi LASCO -- Ops Team UVCS -- John Kohl TRACE -- Charles Kankelborg Relevant Notes -------------- CDS: Monday: Full spectrum full sun scan. Tuesday: 24 hour CME onset watch. Wednesday & Thursday: QS transient events study. Friday: Monitoring active regions on the AR belts. Any extra time may be filled in with sunspot studies. SUMER: Refspecs all week on west limb. UVCS: Coronal hole studies in south and synoptics. LASCO: C2 and C3 synoptics. EIT: Half resolution 195 Angstrom CME watch and synoptics. MDI: Cropped full disk magnetograms and dopplergrams in best focus for continuous contact. TRACE: Active region studies most likely. AOB: ---
