PERIOD COVERED:  0000Z (UTC) 09/10/96 - 0000Z (UTC) 09/11/96

Daily Status Report as of 255/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FGS 6882 (Companion to GL6230)

       The FGSs were used to make POS and TRANS mode astrometric =
observations of star GL623 (aka, Gleise 623) looking for possible =
companions.  Five other reference stars were also used.  From these data =
the precise parallax, barycentic orbits, and accurate masses of the star =
and its companion will be determined.  The observations were completed as =
schedule, and no anomalies 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 QDOTULIR06. 
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 FOC/96 6349 (Snapshot search for High Redshift QSOs with =
Far-UV Flux)

       The Faint Object Camera (f/96) was used to make snapshot images of =
the quasi-stellar object Q0032-375.  This is to determine if this high =
redshifted object has a far ultraviolet flux.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.4 Completed WF/PC-2 6584 (Interaction of Supernovae With =
Curcumstellar Material)

       The WF/PC-2 was used to make observations of Supernova SN1995N. =
The objective is to study the interaction between the supernova and the =
remnant circumstellar material from the progenitor star, and how that =
interaction can sustain supernovae luminocity for long periods.  As =
reported in yesterday's report, there were at least two losses of lock =
near the beginning of this proposal by 254/065438Z (the earlier part of =
the acquisition occurred in the ZOE). The take data flag remained down =
until 254/065911Z.  HSTAR 5708 was written.  Otherwise, the observations =
were completed as planned, and no further problems were reported.

   1.5 Completed WF/PC-2 7203 (Cosmology with the Medium Deep Survey - =
Short Orbit Cases)

       The WF/PC-2 was used to take short (about 20-minute) exposures, to =
be taken in parallel with the prime science observations, using the I =
filter.  These exposures are part of the medium-deep survey, which =
emphasizes exposures that will be useful in obtaining cosmological =
parameters.  As reported yesterday, at 254/082539Z a loss of lock =
occurred, and one of the exposures was shortened.  HSTAR 5706 was =
written.  Otherwise, the observations were completed as planned, and no =
further problems were reported.

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

       The WF/PC-2 was used to make observations taken in parallel with =
the prime science observations as part of the Medium Deep Sky Survey.  As =
documented in HSTAR 5709, there were losses of lock at 254/1133Z, =
254/1143Z, and 254/1511Z during the execution of this proposal.  Each =
occurrence caused the take data flag to go down with resultant loss of =
science data.  Otherwise, the observations were executed as scheduled, =
and no further problems were reported.

   1.7 Completed FOC/48 6199 (Cycle 5: f/48 Long Slit Spectrograph =
Wavelength Calibration)

       The Faint Object Camera (f/48) was used to make wavelength =
calibration observations of the long slit spectrograph.  This was done by =
taking extended line emission observations of the source NGC-6543.  The =
observations were completed as planned, and no problems were reported.

   1.8 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.

   1.9 Completed WF/PC-2 6360 (A Snapshot Survey of "Radio Loud" IRAS =
Galaxies)

       The WF/PC-2 was used to make snapshot survey observations of the =
radio loud IRAS galaxy GAL-1450+0.  The WF/PC-2 was used to discern high =
surface brightness structures in its post-starburst active nuclear =
regions.  The observations were completed as scheduled, and no anomalies =
were reported

   1.10 Completed GHRS/2 6530 (The Wind Momentum: Luminosity Relationship =
for LMC A and B Supergiants)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations the A/B class, supergiant star HD32034 which =
is located in the Large Magellanic Cloud.  These data are part of a large =
effort to calibrate the wind momentum-luminosity function for supergiant =
stars.  The observations were completed as planned, and no problems were =
reported.

   1.11 Completed WF/PC-2 6365 (A Snapshot Survey For Companions and =
Clusters around Wolf-Rayet Stars)

       The WF/PC-2 was used to make snapshot observations of Wolf-Rayet st=
ar WR6 in order to look for companion stars and clusters.  Photometry was =
performed on the Wolf-Rayet star and associated stars.  The observations =
were completed as planned, and no anomalies were reported.
