PERIOD COVERED:  0000Z (UTC) 09/19/96 - 0000Z (UTC) 09/20/96

Daily Status Report as of 264/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6903 (WF/PC-2 Cycle 6 Calibration: =
Decontamination)

       The WF/PC-2 was used to make several calibration bias =
observations, internal flats, K-Spot images and dark calibration images =
which are all part of a Cycle 6 decontamination procedure.  No science =
was interleaved with the dark exposures.  The observations were completed =
as scheduled, and no problems were reported.

   1.2 Completed FOS/BL 6831 (High Speed Photometry of the UV Counterpart =
to 4U1820-30)

       The Faint Object Spectrograph (Blue Side) was used to make Rapid =
Mode, ultraviolet, spectrographic observations of the counterpart of =
x-ray, binary object 4U1820-30.  The target is a low mass binary system =
with an orbital period of 11 minutes.  Approximately fifteen minutes =
after this 8-hour proposal began, at 263/015112Z, there were two FOS =
status buffer messages that indicated that the mode 2 target acquisition =
had failed.  HSTAR 5716 was written.  Otherwise, the observations were =
executed as scheduled, and no further anomalies were noted. 

   1.3 Completed WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: Earth Flats)

       The WF/PC-2 was used to make observations of the bright earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.4 Completed FOS/RD 6696 (Studying the UV Emission line Spectrum of =
High Z radio Galaxies)

       The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet spectrographic observations of the extended line regions in =
the high Z, radio galaxy PKS0349-27.  Several different locations within =
the object were observed.  The observations were completed as planned, =
and no problems were reported. 

   1.5 Completed WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were =
reported.

   1.6 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

       The WF/PC-2 was used to make observations taken in parallel with =
the prime science observations as part of the Medium Deep Sky Survey.  =
The observations were executed as scheduled, and no problems were =
reported.

   1.7 Completed GHRS/2 6078 (The Wind Momentum-Luminosity Relationship =
for SMC A and B Supergiants.)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the O/B class star AV683 which IS located =
in the Small Magellanic Cloud in order to measure the wind =
momentum-luminosity relationship in this low metallicity stars.  This =
relationship is used to determine the distance to galaxies.  The =
observations were completed as planned and no problems were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 6
                                        Successful : 6

       The guide star acquisition at 264/071300Z defaulted to fine lock =
backup on one FGS only.  HSTAR 5717 was written.

                          Scheduled Reacquisitions : 10
                                        Successful : 10

   2.2 FHST Updates: 

                              Scheduled : 14
                             Successful : 14

   2.3 Operations Notes: 

       There were no reported operational problems.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
