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.
