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.
