PERIOD COVERED:  0000Z (UTC) 08/16/95 - 0000Z (UTC) 08/17/95

Daily Status Report as of 229/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WF/PC-2 6189 (WF/PC-2 Cycle 5 Calibration:
Internal Monitor - Vis Flats)

       The WF/PC-2 was used to make internal visual flat calibration images. 
Both photometric and narrow-band filters were used.  The observations were
executed as planned, and no problems were reported.

   1.2 Completed Three 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
nebulae NGC-6578, LO1 and NGC-6629 to study their nuclei and to look for
possible companions.  The observations were executed as scheduled, and no
anomalies were noted.

   1.3 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 GL234 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.

   1.4 Completed Two Sets of 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. A total of
six snapshot observations were lost during attempts to playback data as a
result of problems in the STOCC (See yesterday's Flash Report) and the
switch-over to SAMS. All the other science data was successfully recovered.

   1.5 Completed WF/PC-2 5913 (Low Mass Binaries and the Luminosity Function.
)

        The WF/PC-2 was used to make observations of the low mass binary star
system MT007 (a late-type M class dwarf) to study the  local stellar
luminosity function.  The observations were executed as scheduled, and no
anomalies were noted.

   1.6 Completed Two Sets of GHRS/1 5417 (A Search for the Physical Processes
on Jupiter)

       The High Resolution Spectrograph (Side One) was used as part of a
program to observe atomic hydrogen emission at different latitude and
longitudes on the planet Jupiter.  A wave calibration and sky background
observations were made.  The observations were completed as planned, and no
anomalies were reported.

   1.7 Completed WF/PC-2 6279 (Miscellaneous (WC18): Cycle 5)

       The WF/PC-2 was used to make observations of object SS433 to study
stellar birth and death.  The observations were executed as scheduled, and no
anomalies were noted.

   1.8 Completed FOS/RD 6236 (FOS Cycle 5: Location of Spectra and Wavelength
Calibration: Red Side Detector)

       The Faint Object Spectrograph (Red Side) was used to make calibration
observations in order to determine the location of the spectra and to perform
a wavelength calibration.  All observations were internal.  A Taled
calibration was also completed. The observations were completed as planned,
and no anomalies were reported.

   1.9 Completed FGS 6271 (L726-8/UV Ceti)

       The FGSs were used to make astrometric observations of the binary star
L726/UV Ceti to search for a short period low-mass companion around either
component of this binary object.  The observations were executed as
scheduled, and no anomalies were reported.

   1.10 Completed WF/PC-2 5974 (The Evolution of Radio Loud Quasars)

       The WF/PC-2 was used to make observations of the radio loud  large
redshift quasar MRC0142-27.  The purpose is to determine if this galaxy is
from the same parent population as other kinds of radio galaxies already
studied using HST.  The observations were completed as scheduled, and no
problems were reported.

                          Scheduled Reacquisitions : 1
                                        Successful : 1

   2.2 FHST Updates: 

                              Scheduled : 19
                             Successful : 19

   2.3 Operations Notes: 

       A TTR was written to describe a 16 minute, 4 second engineering data
loss due to an equipment problem at STGT.

       Operations are being conducted in the SAMS backup   facility while the
problems in the STOCC are being diagnosed and corrected.  No operational
problems were encountered.
