SOHO Daily Meeting Minutes for Monday, 19 March 2001 ANNOUNCEMENTS ------------- * The maneuver scheduled for May 31 is likely to be postponed until late June (suggested date is June 28). FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: None Accomplished Activities: 075: VIRGO, RSL 076: VIRGO, SWAN 077: VIRGO, Flight S/W Maint. Planned Activities: VIRGO, CELIAS, New tracking star, mag = 6.8 Upcoming Operations: None Ground Anomalies: 075/2034 Degraded telemetry from D46 for 32.5 minutes due to an extra data source being sent to the POCC. Recoverable. 076/0313 LMC crashed at D34, resulting in the loss of monitor data for 18 minutes. 076/1847 Degraded telemetry from D27 caused by SOHO and POLAR flowing high rate telemetry simultaneously through Goldstone. Recoverable. 077/0200 D46 had problems acquiring telemetry, and then transmitting clean data due to a LNA failure. AOS was 21 minutes late, but data was covered by D24. Degraded data was received from 0217 until 0704 (4 hrs 47 min). Not recoverable. 077/1847 Exciter tripped off unexpectantly, resulting in a 4 min delay of commanding activities during a coherency swap. 077/2058 Degraded telemetry from D16 from 2058 until 2115 (17 minutes). Cause unknown. Recoverable.
