PERIOD COVERED:  0000Z (UTC) 05/23/96 - 0000Z (UTC) 05/24/96

Daily Status Report as of 145/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two 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.  A Taled calibration =
observation was also taken.  The observations were completed as planned, =
and no anomalies were reported.

   1.2 Completed Two Sets of WF/PC-2 6346 (Snapshot Survey of the =
Ultraluminous IRAS Galaxy Sample-Part 1 High)

       The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous IRAS galaxies Qdotulir13 and IR09427+19.  These data will =
be searched for multiple cores, which imply a merger has occurred, and =
for starburst regions.  The observations were executed as scheduled, and =
no anomalies were noted.

   1.3 Completed FOS/BL 6781 (Soft X-Rays and the UV Spectra of a =
Complete QSO Sample)

       The Faint Object Spectrograph (Blue Side) was used to obtain =
ultraviolet spectra of the low-Z quasi-stellar object PG1444+407.  The =
ionization continuum of this object has been studied using the ROSAT =
satellite.  The strengths and line profiles of strong and weak =
ultraviolet emission and absorption lines and the ultraviolet continuum =
were studied.  The observations were completed as planned and no =
anomalies 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 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.

   1.5 Completed FOS/96 6309 (Determining the SED of an Ultraviolet Flare =
at the Center of an Elliptical Galaxy.)

       The Faint Object Camera (f/96) was used to make observations of an =
ultraviolet flare at the center of the elliptical galaxy NGC-4552 which =
brightened in luminosity from 1991 to 1993 by over a factor of seven.  =
The purpose of the observations is to measure the spectral energy =
distribution (SED) of this flare.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.6 Completed FOS/BL 6333 (Physical Conditions in the Narrow-Lined =
Region)

       The Faint Object Spectrograph (Blue Side) was used to make =
observations of the active galactic nuclei located in the Seyfert galaxy =
NGC-3393 in order to determine the physical conditions in its narrow line =
region.  The observations were completed as planned, and no problems were =
encountered.

   1.7 Completed Two Sets of WF/PC-2 5971 (HST Medium Deep Survey)

       The WF/PC-2 was used to make two long exposures 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.

   1.8 Completed FOS/BL 6766 (Narrow Line Seyfert 1S and the Iron Enigma =
in Active Galaxies)

       The FOS (Blue Side) was used to make observations of the 1S class =
narrow lined Seyfert galaxy AKN564 in order to study its iron enigma.  =
These data should show correlations between its x-ray spectra, =
kinematics, and Fe II spectra.  The observations were completed as =
planned and no problems were reported
