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

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.
