PERIOD COVERED:  0000Z (UTC) 10/30/95 - 0000Z (UTC) 10/31/95

Daily Status Report as of 304/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  The =
observations were completed as scheduled, and no problems were reported.

   1.2 Completed WF/PC-2 5972 (Determination of the Extragalactic Distance =
Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-2541 =
looking for standard candle Cepheid variable stars.  The purpose of these =
observations is to help estimate the Hubble constant with an accuracy of =
10%.  The observations were executed as scheduled, and no anomalies were =
noted.

   1.3 Completed WF/PC-2 5999 (The Nuclear Structure of S0 Galaxies: A PC =
Imaging Survey)

      The WF/PC-2 was used to make observations of S0 class galaxy =
NGC-1332 in order to study its nuclear structure.  This is a part of a =
large survey of S0, E/S0, and S0/a class galaxies.  The targets will cover =
a wide range in luminosity and environment.  The observations were =
completed as planned, and no anomalies were noted.

   1.4 Completed WF/PC-2 5839 (Gamma Ray Burst Counterparts in the =
Ultraviolet)

       The WF/PC-2 was used to make ultraviolet observations of object =
GRB790406 which is thought to be an optical counterpart of a gamma ray =
burster.  Three filters from the blue to the ultraviolet were used.  The =
observations were completed as scheduled, and no anomalies were noted.

   1.5 Completed FGS 6063 (Continuation of Mass Ratio Determination for =
Doubles)

       The Fine Guidance Sensors were used to make POS and TRANS mode =
astrometric observations of double star L722-22-00.  This binary star =
system contains a low mass star and a brown dwarf.  The observations were =
completed as scheduled, and no anomalies were noted.

   1.6 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.

   1.7 Completed GHRS/2 6261 (Structure in Moderate Column Density, Low =
Redshift Lyman Alpha Absorbers)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of low redshift quasar PG1116+215 to study the =
structure in the Lyman-Alpha absorption associated with galaxies along the =
line of sight.  A wavelength calibration image was also taken.  The =
observations were executed as scheduled, and no anomalies were noted.
