1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/BL 5656 (WF/PC-2 Cycle 4 Calibration: Internal 
       Monitor. 2: Flats Part 2)

       The Faint Object Spectrograph (Blue side) was used to make
       calibration observations of star HD207757 (aka, AG Pegasi) and
       object NGC-188-225.  A total of seven observations was received, and
       have not yet been completely analyzed. However, some of the target
       acquisition data was received in real-time. The peakups had maximum
       counts in groups 1 and 3, but the counts were much lower than the
       previous set using the old flight software and appeared to have
       missed the target. At the present time no explanation has been
       found. 

   1.2 Completed GHRS/1 5594 (GHRS Side 1 Sensitivity Monitor: Cycle 4)

       The High Resolution Spectrograph (Side One) was used to make
       calibration observations of star BD28D4211 to monitor the long-term
       sensitivity of the system. A total of fourteen observations was
       received, but not displayed due to lack of time. The target
       acquisition was seen in real time and the target was in map 5 of the
       5X5 spiral search, with a target search flux of 7135 counts. The
       Small Science Aperture peakup (5X5) found the target at the eighth
       dwell point with a target flux of 4259 counts. No anomalies were
       noted. 

   1.3 Completed WF/PC-2 5568 (WF/PC-2 Cycle 4 Calibration: Decon)

       The WF/PC-2 was used to make internal flat calibration
       observations, K-Spots, and darks as part of a decontamination
       operation. Six observations were received, but there was not enough
       time to display them. No anomalies were noted. 

   1.4 Completed FOC/96 5526 (FOC UV Throughput Monitoring: Cycle 4)

       The Faint Object Camera (f/96) was used to make calibration
       observations of BPM16274. The first observations were received and
       displayed in real-time. A corrective pointing maneuver was
       successfully calculated, and uplinked to the spacecraft. The target
       was placed at the fiducial point of the aperture. No anomalies were
       noted. 

   1.5 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal 
       Monitor. 1)

       The WF/PC-2 was used to make several internal bias, K-Spot, and flat
       calibration observations to monitor the CCD camera electronics, the
       optical alignment, and to check for contamination. The observations
       were executed as scheduled, and no anomalies were noted. 

   1.6 Completed WF/PC-2 5563 (WF/PC-2 Cycle 4 Photometric Calibration 
       Monitor 1: UV/OPT STD) 

       The WF/PC-2 was used to make photometric calibration images of
       ultraviolet standard star GRW+70D582 and monitor the photometric
       stability and quantum efficiency of the WF/PC-2. A Loss of Lock
       (LOL) occurred during the observations (See Operations Note 2.4).
       The observational data has not yet been received. The DOC is working
       on a Line Outage Recorder (LOR) playback. Analysis is pending the
       receipt of the data. 

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions: 


                            Scheduled Acquisitions : 5
                                        Successful : 5
                          Scheduled Reacquisitions : 10
                                        Successful : 10

                          A Loss of Lock (LOL) occurred at 165/0938Z near a
                          Day/Night transition. The Take Data Flag (TDF)
                          dropped and science data observations were lost.
                          Subsequence lock operations were successful. 

   2.2 FHST Updates: 

                              Scheduled :11
                             Successful :11

   2.3 Significant HSTARs: None

   2.4 Operations Notes: 

       The HST observatory experienced a quiet day as each subsystem
       reported nominal performance. 

3.0 ANOMALY STATUS:

   4.1 Significant New Anomalies: None

   4.2 Significant Unresolved Anomalies: None

4.0 SIGNIFICANT FORTHCOMING EVENTS:
