FOT REPORT ---------- Spacecraft Status: Nominal Spacecraft Anomalies: Nominal Accomplished Activities: DOY 123: VIRGO, SWAN, RSL DOY 124: VIRGO DOY 125: VIRGO Planned Activities: VIRGO Upcoming Operations: None Ground Anomalies: 124/0425 D46 antenna had to stow due to fire alarm at site. Emergency record script executed. Lost 28 minutes of MDI high rate data. 124/0623 Wayward command delayed pass activities two minutes. 124/1325 Unable to establish a solid command link on D27. D16 brought up as a replacement. Unable to command for 1 hour 19 minutes. 124/1459 Lost uplink on D16 due to the antenna going to brake. Delayed commanding activities 9 minutes. No data loss. 124/1522 ACU anomaly, TC timeout between words, resulted in the CRS drift estimate command being rejected. Manually updated the CRS drift value. 125/1613 Received degraded TLM from 1613 to 1700 (47 minutes) due to a RCVR failure at D7. Lost data is unrecoverable. 125/2131 NRT activities delayed until upcoming D46 support due to the inability to establish a solid uplink on D27.
