PERIOD COVERED:  0800 EST
Daily Status Report as of 071/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOC/96 3591 (Massive Stars in Starburst Galaxies - 
       FOC Images)

       The Faint Object Camera (f/96) was used to make observations of the
       star bursting galaxy IZW18 to investigate the physics of its massive
       stars, and the processes which drive the galaxy's formation and
       evolution. The observations were executed and scheduled, and no
       problems were reported. 

   1.2 Uplinked Updated Ephemeris Tables, Per MOSES 2871 

   1.3 Completed FOC/96 4800 (Stellar Content of Wolf-Rayet Galaxies)

       The Faint Object Camera (f/96) was used to make one image of the
       Wolf-Rayet Galaxy MARK1236. The observation was reported to have
       produced an excellent image of the galaxy. 

   1.4 Completed HSP/POL 3557 (Polarimetric Observations of the Crab Nebula
       Pulsar in the UV) 

       The High Speed Photometer was used to make ultraviolet polarimetric
       observations of the Crab Nebula Pulsar. Simultaneous radio telescope
       observations will be made, and a comparison of the pulse profiles
       and polarizations will be made. The onboard target acquisitions were
       successful. Four polarimetric observations were made. One of the
       observations was not received, because of a rejected downlink. The
       other three observations were reported to be okay. 

   1.5 Completed WFC 1306 (GTO Low Latitude Parallel Program)

       The Wide Field Camera was used to make four low latitude
       observations which were taken in parallel with the prime science
       observations. All four observations were reported to be
       satisfactory. 

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 3
                                        Successful : 3
                          Scheduled Reacquisitions : 9
                                        Successful : 9
                                    Losses of Lock : 0

   2.2 FHST Updates: 

                              Scheduled : 6
                             Successful : 6

   2.3 Significant HSTARs: 

       HSTAR 3919 - The EPS/DMS group is investigating a telemetry channel
       failure on DIU2. Seven monitors were reported to have gone to their
       zero state (i.e., they showed miscompares) at Friday (071/0002Z).
       Preliminary data indicates possible failure of -AA Trim Relay at the
       same time. 

   2.4 Operations Note: None
