Spacecraft Status: Nominal, HGA Position Monitoring Disabled, HGA Nominal Control Disabled

Spacecraft Anomalies: 172/1357 CEPAC ESU Data Request Error; recovered autonomously after 4 minutes. 174/0357 Single DMA failure over 1 format occurred during heavy NRT commanding by LASCO.

Accomplished Activities: DOY 171: VIRGO, SWAN, MDI, RSL, New tracking star, mag = 7.45 OCD #1795: Lower APMM Thermal Settings OCD #1796: HGA Z-Axis Movement at Low APME Temps OCD #1797: Stabilize APMM Temperatures DOY 172: CELIAS OCD #1798: Z-Axis High Speed Movement with APME-A, Stable Motor Temps DOY 173: CELIAS

Planned Activities: CELIAS, SWAN, NONCOHO_03174

Upcoming Operations: None

Ground Anomalies:

171/0435 Delayed carrier operations on D66 due to problems with their transmitter. Lost 11 minutes of command ability.

171/1403 Received degraded TLM from D27 from 1303 to 2120 due to bandwidth overflow at JPL. Data should be recoverable from the CDR.

171/1439 Commands were being corrupted at D16 due to problems with their command modulation settings. Pass activities delayed 36 minutes.

171/1700 DPS POCC products could not be delivered due to a file system problem. Delivery of POCC products delayed. No real-time operational impacts.

172/0403 SH4WS2 terminal hung, cause unknown. Operations temporarily moved over to String 5. SH4WS2 down from 0403 until 0438.

172/1405 Received degraded TLM from D16 from 1405 until 0130 due to a line overflow at JPL, cause unknown. MDI high rate data collected in VC3 vice VC2. All data recoverable from the CDR.

172/1644 Lost a total of 2.5 minutes of telemetry due to problems with auto-track at D16. Lost data is unrecoverable.

173/0440 D66 antennna RED due to a MPA failure. Lost 530 minutes of TLM and CMD ability. Data recoverable from the SSR and from D54 supplemental support. MDI continuous campaign disrupted from 0440 to 1239.

173/1412 Received degraded TLM from D16 from 1412 to 1800 due to a line overflow at JPL. Data should be recoverable from the CDR.

174/0755 Received degraded TLM from D66 from 0755 until 1026, cause unknown. Poor data quality confirmed by JPL. Lost data should be recoverbale from the CDR.
