PERIOD COVERED:  0000Z (UTC) 10/05/95 - 0000Z (UTC) 10/06/95

Daily Status Report as of 279/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FGS 6036 (Detection and Mass Determination of Low Mass
Companions to nearby M Dwarf)

       The FGSs were used in both the POS and TRANS Modes to make astrometric
observations of low mass companions to M class dwarf star GL275 and four
reference stars.  This will lead to a mass determination for the stars.  The
observations were completed as planned, and no anomalies were noted.

   1.2 Completed WF/P-2 6254 (GTO Pure Parallel Program - Cycle 5)

       The WF/PC-2 was use to make random long exposures of high galactic
fields taken in parallel with the prime science observations to obtain a
random sample of galaxies.  The observations were executed as scheduled, and
no anomalies were noted.

   1.3 Completed FOC/96 6161 (FOC/96 Cycle 5 Aperture Location Monitor)

       The Faint Object Camera was used to make astrometric standard field
observations of NGC-188-51 to monitor the location of the camera's f/96
apertures with respect to the V2-V3 coordinate frame.  A dark calibration
image was also taken.  The observations were completed as scheduled, and no
problems were reported.

   1.4 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 concurrent 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.

   1.5 Completed WF/PC-2 6009 (Jovian Stratospheric and Tropospheric
Circulation and Structure)

       The WF/PC-2 was used to make high resolution, multi-filter
observations of the planet Jupiter to study its stratospheric and
tropospheric circulation and structure.  This study is being done several
months before and after the Galileo probe enters the atmosphere on Dec. 7,
1995.  The observations were completed as scheduled, and no anomalies were
reported.

   1.6 Completed FGS 6047 (Calibrating the Mass Luminosity Relation at the
End of the Main Sequence)

       The FGS were used to make astrometric observations of star GL748 as
part of a study to determine its mass luminosity relationship.  The purpose
is to measure the precise parallax and relative orbit of its faint companion.
 The observations were completed as planned, and no problems were reported.

   1.7 Completed WF/PC-2 6095 (Hot Stellar Populations in Globular Cluster
Cores)

       The WF/PC-2 was used to make observations of globular cluster NGC-1851
to study the radial gradients of the hot stellar population in its core
region.  Observations were made in the blue, violet and far ultraviolet.  The
observations were completed as planned, and no problems were reported.

   1.8 Completed Two Sets of WF/PC-2 6119 (Snapshot Survey for Companions of
Planetary Nebula Nuclei)

       The WF/PC-2 was used to make snapshot survey observations of planetary
nebula NGC-3195 to study its nuclei and to look for possible companions.  The
observations were executed as scheduled, and no anomalies were noted.

   1.9 Completed WF/PC-2 6295 (Imaging the Atmosphere of Titan and Its
Surface)

       The WF/PC-2 was used to make ultraviolet and near infrared
observations of Saturn's Largest moon Titan to study its atmosphere and
surface.  The observations were taken near Saturn's opposition.  The
observations were executed as scheduled, and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 6
                                        Successful : 6

       The acquisition at 279/043438Z intitally failed due to
       the scan step limit being exceeded.  The second 
       attempt resulted in the acquisition failing to fine 
       lock back-up on FGS-1 only.  HSTAR 5323 was written.

                          Scheduled Reacquisitions : 11
                                        Successful : 11

   2.2 FHST Updates: 

                              Scheduled : 15
                             Successful : 15

   2.3 Operations Notes: 

       There were data inversions during STGT operations.
       A TTR was written.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
