PERIOD COVERED:  0000Z (UTC) 10/24/95 - 0000Z (UTC) 10/25/95

Daily Status Report as of 298/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed 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-2371 to study its nuclei and to look for possible =
companions.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.2 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flats)

       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.

   1.3 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.

   1.4 Completed FOS/RD 6019 (Supersonic Velocity Dispersion in Dwarf Nova =
Accretion Disks)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the dwarf nova X-Cha (aka, OY Carat in =
order to study its supersonic velocity dispersion.  The intent is to nail =
down the physical support mechanism for its accretion disk of this short =
period eclipsing dwarf nova.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.5 Completed Three 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.  =
The observations were completed as planned, and no problems were reported.

1.6 Completed FOS/BL 5346 (B-Supergiants in Post MS Gap)

       The FOS (Blue Side) was utilized to look at the predicted gap in =
the H-R diagram of SK-68-11 to see if it is filled with early B =
supergiants.  The instrument will obtain high S/N spectral data of four =
early B supergiants in the LMC to discriminate between various =
evolutionary scenarios and to constrain new stellar evolution scenarios.  =
There were no reported operational problems.

   1.7 Completed 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.

   1.8 Completed Three Sets of 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.  The observations were =
completed as planned, and no anomalies were reported.

   1.9 Completed GHRS/2 5961 (The D/H Ratio in Double QSO Absorption =
System Towards Q0454+220)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the Lyman Alpha line toward QSO Q0454-220 =
in order to study the Deuterium to Hydrogen ratio.  A wavelength =
calibration image was also taken.  The observations were completed as =
planned, and no problems were reported.

   2.3 Operations Notes: 

       There were data inversions during STGT operations due to a command =
hit on TDW.
