PERIOD COVERED:  0000Z (UTC) 02/21/96 - 0000Z (UTC) 02/22/96

Daily Status Report as of 053/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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.

   1.2 Completed GHRS/1 5877 (The 11B to 10B Ratio in the Interstellar =
Medium.)

        The High Resolution Spectrograph (Side One) was used to make =
spectrographic observations of the bright star HD38771 in order to study =
the foreground interstellar medium.  This is to measure the abundance =
ratio of two boron isotopes.  The observations were completed as planned, =
and no problems were reported.

   1.3 Completed Two Sets of WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: =
Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images.  =
These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.4 Completed WF/PC-2 6344 (Low - Mass Binaries in the Hyades - =
Completing the Survey)

       The WF/PC-2 was used to make observations of the low mass binary =
star RHY369 (M-Class Dwarf Stars) which is located in the Hyades Cluster.  =
The observations were executed as scheduled, and no anomalies were noted.

   1.5 Completed WF/PC-2 6365 (A Snapshot Survey For Companions and =
Clusters around Wolf-Rayet Stars)

       The WF/PC-2 was used to make snapshot observations of Wolf-Rayet =
star WR125 in order to look for companion stars and clusters.  Photometry =
was performed on the Wolf-Rayet star and associated stars.  The FGS =
acquisition, at 053/073226Z, for this proposal failed.  During the =
acquisition attempt low PMT counts were observed.  The HST was also in the =
SAA during the period.  Five observations were affected.  HSTAR 5509 =
documents these events.  Otherwise, the observations completed as planned, =
and no further anomalies were reported.

   1.6 Completed FOS/RD 5852 (Lyman-alpha Forest Cloud Sizes and =
Clustering at Z~0.5)

      The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of QSO MC1146+111 to study its Lyman-Alpha =
forest and its relation to other nearby QSOs.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.7 Completed FOS/RD 6025 (Consequences of the Shoemaker-Levy Impact =
With Jupiter)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the planet Jupiter in order to study the consequences of =
the impact of the comet Shoemaker-Leve with the planet.  The observations =
were completed as scheduled and no anomalies were noted.

   1.8 Completed GHRS/2 5885 (GHRS- Observations of Candidate =
Beta-Pictoris Circumstellar Gaseous Disks)

       The High Resolution Spectrograph (Side Two) was used to make =
observation of star HD158643 which is a candidate to have Beta =
Pictoris-like gaseous disks.  The objective is to confirm the existence of =
circumstellar gas, and to understand its origin.  The observations were =
completed as planned, and no anomalies were reported.

   1.9 Completed WF/PC-2 6118 (HST Observations of Two Ultraluminous =
Extragalactic Supernova Remnants)

       The WF/PC-2 was used to make observations of the ultraluminous =
extragalactic supernova remnant NGC-4449.  This is one of the brightest =
supernova remnants known.  Its high luminosity may be caused by =
interaction with its local environment.  The observations were completed =
as scheduled, and no problems were reported.

   1.10 Completed WF/PC-2 5971 (HST Medium Deep Survey)

       The WF/PC-2 was used to make a long exposure medium deep sky survey =
observations at latitudes larger than 10 degrees taken in parallel with =
the prime science observations.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.11 Completed FOS/BL 6166 (FOS Cycle 5: Location of Spectra and =
Wavelength Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make =
wavelength calibration images to measure the stability of the FOS Blue =
Side wavelength scale and spectral locations.  A Taled calibration =
observation was also taken.  The observations were completed as planned, =
and no anomalies were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 9
                                        Successful : 8

       One acquisition, at 053/073226Z, failed.  Low PMT counts were =
observed, and the acquisition did occur in the SAA.  HSTAR 5509 was =
written.
