PERIOD COVERED:  0000Z (UTC) 09/04/96 - 0000Z (UTC) 09/05/96

Daily Status Report as of 249/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6348 (Blue Continuum Snapshots of 3CR Radio =
Galaxies)

       The WF/PC-2 was used to make some snapshot images of the blue =
continuum in radio galaxy 3C303.0.  Combined with existing data, these =
exposures will provide high spatial resolution information on the color =
distribution within galaxies, redding due to dust, spacial indices of the =
optical synchrotron jets, and colors of the active nuclei and tidal jets. =
 The observations were executed as scheduled, and no anomalies were =
noted.

   1.2 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 MARK493 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

   1.3 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.

   1.4 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

       The WF/PC-2 was used to make some medium deep observations in =
parallel with the prime science observations.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.5 Completed GHRS/1/2 6786 (HST Observations of Io's Atmosphere =
Coordinated with the Galileo Probe)

       The High Resolution Spectrograph (Both Sides One and Two) was used =
to make observations of the moon Io during its egress from behind the =
Planet Jupiter.  These observations will be coordinated with other =
observations taken from the Galileo Probe in orbit around the planet =
Jupiter in order to study Io's atmosphere.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.6 Completed WF/PC-2 6437 (Sins: Supernova Intensive Study - Cycle 6)

       The WF/PC-2 was used to make observations of the supernova =
SN-1992A and its circumstellar matter which is located in the Large =
Magellanic Cloud.  The observations were completed as planned, and no =
problems were noted.

   1.7 Completed WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: Earth Flats)

       The WF/PC-2 was used to make observations of the bright Earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.8 Completed GHRS/1/2 6594 (White Dwarf Companions of Barium and CH =
Peculiar Stars)

       The High Resolution Spectrograph (Sides One and Two ) was used to =
attempt to make spectrographic observations of the white dwarf of the =
Barium and CH Peculiar class star HD46407.  This will test the theory =
that abundance anomalies in this star caused by mass transfer from the =
precursor of the white dwarf.  The observations were executed as =
scheduled, and no anomalies were noted.

   2.3 Operations Notes: 

       HST operations transitioned to the SAMS back-up facility at =
249/0800Z in preparation for today's simulation.
