SOHO Daily Meeting Minutes for 31 March 1999 Chaired by: L. Roberts (S0C) Notes: K. Schenk (EIT) FOT Briefing ------------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: RSL, VIRGO, CELIAS, Extra VC2 (2000-2200) Planned Activities: VIRGO, CELIAS, Extra VC2 (2000-2200) CDMU/ACU Memory Dumps (Overnight) Ground Anomalies: 089/2027 - Degraded TM; Line overflow during VC2 (8 min, recov) 090/0750 - D54 Transmitter mask delayed carrier up (22 min delay) 090/1019 - D54 Transmitter cooling problem; Commanding unavailable (89 mins) 090/1117 - Command lost during transmission (2 min delay) SOLAR STATUS ------------ SOLAR ACTIVITY FORECAST: SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW WITH A CHANCE OF ISOLATED C-CLASS EVENTS FROM REGION 8502. GEOPHYSICAL ACTIVITY FORECAST: THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED. A HIGH SPEED STREAM COULD CONTINUE TO ELEVATE ACTIVITY SLIGHTLY OVER THE NEXT THREE DAYS. 3/30 DOY 089: 15:54 UT C2 sees a fast jet off NNE limb 21:48 UT EIT sees jet out of AR8502 3/31 DOY 090: 01:13 UT eruptive filament/prominence on NW, C2 sees a small CME at 01:54 off West limb 05:34 UT C2 sees a jet off NNE limb which later develops into a nice CME, later in C3 at 05:47 and produces a 'heart' shaped figure over the North Pole. 13:36 EIT sees a CME from SW limb from AR 8495. GOES activity very low 'B' class INSTRUMENT STATUS ----------------- CDS: Nominal. Equatorial Coronal Hole stdies. Flarewatch with TRACE today. Tomorrow synoptic, flarewatch or spectra studies and GIS engineering. SUMER: Not observing. UVCS: Nominal. Performed synoptics and the Jupiter/Galileo observation program. LASCO: Nominal. C2 and C3 synoptics while CME watching. C2 Jupiter observations 10:00-11:00 UT at 2.5 min cadence. EIT: Nominal. 195A CME Watch full field full resolution. MDI: Nominal. Continously performing Continuous Dynamics campaign. Campaign reload scheduled later today. TRACE: Nominal. Flarewatch campaign at AR8502. Tomorrow will begin a South Pole program for the Galileo observations.
