SOHO Daily Meeting Minutes for Thursday, 29 June 2000 FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: VIRGO, CELIAS, 26 Meter Automation Demo Track Planned Activities: VIRGO, CELIAS, Nom. HGA Table, Acquire new tracking star, mag = 7.1 Upcoming Operations: July 18: Stationkeeping & Mom. Management Maneuvers Ground Anomalies: 180/1225 Command outage from 1225 to 1226 and again at 1230 to 1231 due to PA failure (Klystron airflow fault) at D16. This occurred during the 26m automation demo track. 180/1240 Lost 2 minutes of recoverable TLM due to a TCP failure at D16. This occurred during the 26m automation demo track. 180/1432 Wayward command. Lost one command which never reached Station D16; cause unknown. Delayed commanding activities 43 minutes for investigation. 180/2340 Wayward command. Lost one command which never reached Station D16; cause unknown. Delayed commanding activities 2 minutes. 181/0124 Lost 3 minutes of recoverable TLM due to a failure of the Big Pipe between Canberra and JPL. 181/0348 Lost 26.5 minutes of TLM and command ability due to a hydraulic failure of D46's Y-axis controller. Lost data is recoverable from D54, which was up early for the next DSN support. 181/0419 Single command failed to be transmitted to the spacecraft due to a CPA failure at D54. Delayed commanding activities 8 minutes. SOLAR STATUS ------------ SOLAR ACTIVITY FORECAST (UPDATED 28 JUNE AT 22 UT): SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. MOSTLY LOW LEVEL C-CLASS FLARES ARE LIKELY WITH AN ISOLATED CHANCE OF AN M-CLASS EVENT. GEOPHYSICAL ACTIVITY FORECAST: THE GEOMAGNETIC FIELD IS EXPECTED TO BE MOSTLY QUIET TO UNSETTLED WITH ISOLATED ACTIVE PERIODS AT HIGH LATITUDES. 06/28 DOY 180 - 06/29 DOY 181 EIT daily On-Line Solar Status and observations: http://umbra.nascom.nasa.gov/eit/plan/log_form20000629.html LASCO daily On-Line Solar Status and observations: http://lasco-www.nrl.navy.mil/observations/2000/obs20000629.html INSTRUMENT STATUS ----------------- CDS: Nominal. Today - Sunspot study at AR 9057 and flare interrupt study. Friday - Loops on the limb with TRACE, target TBD. SUMER: Nominal. Interested in doing ICAL01 on quiet sun next week. UVCS: Nominal. Yesterday UVCS caught a large CME at 295 degrees, 2.3 Rsun between 19:06 and 00:40 UT. Today - UVCS finishes their CME watch at 16 UT and begins the 24-hour synoptics. Friday - Mars Global Surveyor campaign. LASCO: Nominal. C2 and C3 synoptics. EIT: Nominal. 195 Angstrom CME watch and synoptics. MDI: Nominal. Full disk magnetograms and dopplergrams. TRACE: Nominal. Today - studying the loops that connect AR 9057 and AR 9055, followed by sunspot observations associated with AR 9057. Friday - Observations in a quiet sun area in the East followed by loops on the limb observations with CDS. AOB: JOP128 begins on Saturday. Possible target: AR 9062.
