SOHO Daily Meeting Minutes for 4 November 1999 Chaired by: L. Roberts (SOC) Notes: A. Akmal (UVCS) DOY: 308 FOT Briefing ------------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: VIRGO, Acquired New Tracking Star, mag = 5.8 Planned Activities: VIRGO, HGA Upcoming Operations: Switch to Submode 6 at 22:00 on 11/5 Momentum Management for Leonids on 11/9 Instrument Safing/Leonids Roll Maneuver on 11/16 Post Leonids Roll/Momentum Management/SK Maneuver on 11/19 Ground Anomalies: 0920 SCP Failure at D61. 62 minutes of lost TLM and CMD ability. Data recoverable from the CDR. 1755 Degraded TLM due to external interference. Degraded TLM from 1755 to 1855; unrecoverable. SUMER images impacted. 2249 Receiver at D16 dropped lock for reasons unknown. Two minutes lost data; recoverable. 1107 SFG Interrupt Error. Two minutes lost data; recoverable. SOLAR STATUS ------------ SOLAR ACTIVITY FORECAST: SOLAR ACTIVITY IS EXPECTED TO BE LOW TO VERY LOW. THE ACTIVE LONGITUDES OF THE LAST SOLAR ROTATION WILL ROTATE INTO VIEW OVER THE NEXT FEW DAYS, HOWEVER, THERE IS CURRENTLY NO EVIDENCE OF ANY STRONG ACTIVITY IN THIS AREA. GEOPHYSICAL ACTIVITY FORECAST: THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED EARLY IN THE PERIOD. ACTIVITY IS EXPECTED TO BEGIN TO INCREASE LATE IN THE PERIOD AS A CONSEQUENCE OF THE LARGE EQUATORIAL CORONAL HOLE NOW APPROACHING CM. See EIT activity page: http://umbra.nascom.nasa.gov/eit/plan/log_form19991104.html Plans for Tomorrow: ------------------ F Nov 05 Flare Watch (#6230), SUMER/TRACE, POC: Harry Warren and Werner Curdt, SUMER: 00-08 UT JOP107: Lyman Line Series in Prominences and Lyman Continua (#6235), POC: Terry Kucera, SUMER/CDS (7-12 UT)/TRACE/Ondrejov, 8-12 UT Chromosphere, Transition Region, and Coronal Transient Velocity Program, (#6223), POC: Don Hassler SUMER/TRACE/MDI/EIT/Kitt Peak, 12-20 UT, CDS: 12-15 UT JOP114, Pre-Eruptive Filament Structures (# 6255) CDS/Helio Research/BBSO/HASTA/MICA/LASCO, 15-22 UT Local Coordinator: Jeff Brosius, POC: Nandita Srivastava INSTRUMENT STATUS ----------------- CDS: Nominal. Today: JOP 114, loops on limb campaign starting at 7 UT, for 6 hours. Tomorrow: JOP 107 from 7 to 12 UT, including 1 hour coordinated with SUMER. JOP 114 from 15 to 22 UT. From 12 to 15 UT will either participate in coronal hole study, or look at loops on the limb. SUMER: Nominal. Today, looking at loops on the east limb. UVCS: Nominal. Continuing streamer study, possibly moving to streamer in the NW. LASCO: Nominal. C2 and C3 synoptics while CME watching. EIT: Nominal. Participating in coronal hole study tomorrow, providing 195 A images. CME watch at 12 minute cadence, with full resolution every 12 minutes. MDI: Nominal. In high resolution mode until 7:32 UT today, then switched to full disk mode. TRACE: Nominal. Reviewed yesterday's data and cured pointing anomaly. Participating in coordinated observations listed on calendar for tomorrow.
