SOHO Daily Meeting Minutes for Monday, 23 April 2001 ANNOUNCEMENTS ------------- * SPWG tomorrow at 2 p.m. in EAF. FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: 110: VIRGO, RSL New tracking star, mag = 7.1 New control star, mag = 5.75 111: VIRGO, SWAN, CELIAS 112: VIRGO, CELAIS, Flight S/W Maint. Planned Activities: VIRGO, CELIAS x2 Upcoming Operations: May 1 ACU/CDMU Memory Dumps Ground Anomalies: 110/1906 Lost 2 minutes of recoverable TLM due to a TGC failure at D16. 110/2337 A RNS/SCP failure at SPC-10 resulted in 64 minutes of lost TLM (including the 0000 magnetogram). Data should be recoverable from the CDR. 111/1715 Late AOS from D27 (20 min) due to their azimuth drive going to brake. Due to the uncertainty as to when D27 would have data, the S/C was transitioned through IDLE into RECORD. Lost commanding ability for 24 minutes. 113/0100 Problems with SPC-40's data lines resulted in 20 minutes of lost data. Data should be recoverable from the CDR.
