PERIOD COVERED:  0000Z (UTC) 09/03/96 - 0000Z (UTC) 09/04/96

Daily Status Report as of 248/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two 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 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 galaxy QDOTDELLI.  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 GHRS/1 6070 (Interstellar Tin: Probing Galactic =
S-Process Element Enrichment)

       The High Resolution Spectrograph (Side One) was used to make Echell=
e A observations of star HD144217 in order to probe for interstellar tin =
and to study the galactic S-process neutron capture of element =
enrichment.  The observations were completed as planned, and no problems =
were reported.

   1.4 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 flu=
x 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 WF/PC-2 6905 (WF/PC-2 Cycle 6 Calibration: Internal =
Monitor)

       The WF/PC-2 was used to make several internal calibrations =
observations including biases and internal flats as part of a Cycle 6 =
calibrations procedure.  A variety of internal exposures are run weekly =
to verify and monitor the health of the camera.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.6 Completed WF/PC-2/GHRS/1 6743 (HST Far UV Imaging and Spectra of =
Jupiter's Aurora)

       The WF/PC-2 and the High Resolution Spectrograph (Side One) were =
both used to make observations of the auroral zones on the planet =
Jupiter.  The observations were executed as scheduled, and no anomalies =
were noted. 

   1.7 Completed WF/PC-2 6756 (Measuring Proper Motions of Galactic =
Microlenses)

       The WF/PC-2 was used to make astrometric proper motion measurements=
 of STAR-1804 as part of a study of galactic microlensing.  The =
observations were completed as scheduled, and no problems were reported. 

   1.8 Completed GHRS/2 6455 (Metal Diffusion and Radiative Levitation in =
Hot Helium Rich White Dwarfs)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the hot, helium-rich, white dwarf star =
HD149499 in order to study its metal diffusion and radiative levitation.  =
The observations were executed as planned, and no anomalies were =
reported. 

   1.9 Completed FOS/BL 6498 (Accretion Streams in Magnetic Variables: =
FOS Eclipse of 4 Rosa)

       The Faint Object Spectrograph (Blue Side) was used to make Rapid =
Mode spectrographic observations of the accretion streams in the magnetic =
variable star (i.e., cataclysmic variable) RXJ1940-10.  This is a binary =
system, and it contains a white dwarf star, an accretion disk, a mass =
stream, and hot spot where the mass stream hits the disk and a companion =
star.   The observations were completed as planned and no anomalies were =
reported.

   1.10 Completed GHRS/2 6501 (Probing the Equatorial Ejecta of Eta =
Carinae)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the equatorial ejecta from the Eta-Carinae =
system.  The results will be used to interpret Galileo's magnetosphere =
and auroral data.  The combined data set will yield the relative =
intensity and spatial distribution of auroral activity.  The observations =
were completed as planned, and no problems were reported.
