PERIOD COVERED:  0000Z (UTC) 12/08/97 - 0000Z (UTC) 12/09/97

Daily Status Report as of 343/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOC/96/WF/PC-2/STIS/CCD/NIC/1/2 7697 (Focal Plane
Monitoring Program)

       All of the onboard instruments were used to make astrometric and
alignment observations of the standard stars 415W3, 421W3, 237W3 as part of
the focal plane monitoring program.  The observations were completed as
planned, and no anomalies were reported.

   1.2 Completed WF/PC-2/STIS/CCD/NIC/1/2 7307 (The Formation and Evolution
of Rich Star Clusters in the LMC)

       The WF/PC-2, the Space Telescope Imaging Spectrograph (CCD), and the
Near Infrared Camera (Cameras One and Two) were used to make observations
of the rich star cluster NGC-1805 which is located within the Large
Magellanic Cloud in order to study its formation and evolution.  These
observations will help us understand the origin and evolution of rich star
clusters in our own Galaxy.  The observations were complete as scheduled,
and no anomalies were reported.

   1.3 Completed NIC/2/3 7453 (The SBF Hubble Diagram)

       The Near Infrared Camera (Camera Two and Three) was used to make
deep NICMOS observations of galactic cluster Abell-3389 to determine its
distance using the surface brightness fluctuation {SBF} method.  HST is
essential for its high spatial resolution which makes it possible to detect
and remove globular clusters and background galaxies that contaminate the
SBF measurement.  The observations were executed as scheduled, and no
anomalies were noted.

   1.4 Completed STIS/CCD 7802 (Daily Darks to Update Acquisition Bad Pixel
Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations to obtain daily darks to update the acquisition
bad pixel table.  These darks are intended to identify hot pixels for
update to the acquisition on-board FSW hot pixel table.  Daily hot pixel
lists can also be used for science data analysis.  The observations were
executed as scheduled, and no anomalies were noted.

   1.5 Completed WF/PC-2 7786 (Pure Parallel Archive Survey - Continuation)

       The WF/PC-2 was used to make observations as part of an archival
survey program in which the images were taken in parallel with the prime
science observations.  These WF/PC-2 parallel observations were obtained in
the ultraviolet in a search for interesting objects.  The observations were
completed as planned, and no problems were reported.

   1.6 Completed NIC/1/2/3 7328 (High Resolution IR Imaging Survey (IRIS)
of the Centers of the Nearest Active Galaxies)

       The Near Infrared Camera (Camera One, Two and Three) was used to
make high resolution infrared observations of the nearest active Markarian
galaxy NGC-4235 in order to study its inner nuclear region.  Observing in
the near-IR minimizes the dust obstruction and maximizes sensitivity to the
old stellar population which dominates the mass.  The  observations were
executed as scheduled, and no anomalies were noted.

   1.7 Completed WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental Darks PT1/3)

       The WF/PC-2 was used to make supplemental dark calibration images.
This set of calibrations is intended to obtain three dark frames every day
to provide data for monitoring and characterizing the evolution of hot
pixels.  The observations were executed as scheduled, and no anomalies were
noted.

   1.8 Completed  WF/PC-2 6549 (Calibration of Nearby Type Ia Supernovae as
Standard Candles: NGC 3627 and SN 1989B)

       The WF/PC-2 was used to make observations of the Type Ia supernova
SN 1989B which is located in galaxy NGC-3627.  The experiment is designed
to determine the mean absolute magnitude of the B and V of SNe Ia, and how
large the dispersion is about this mean.  The observations were completed
as planned, and no problems were reported.

   1.9 Completed NIC/2/3 7811 (NICMOS Modified One Orbit Parallel)

       The Near Infrared Camera (Cameras Two and Three) was used to obtain
"JH" imaging, and G096 and G141 spectroscopy of sky regions when another
instrument is prime.  The observations were completed as planned, and no
anomalies were reported.

   1.10 Completed Two Sets of STIS/CCD 7781 (STIS Non-Scripted Parallel
Archive Proposal - Full Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one full orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.11 Completed WF/PC-2 6431 (Determination of the Extragalactric
Distance Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-3319 to
be used in measuring the periods of Cepheid variable stars within this
galaxy.  This will allow for a more accurate estimate of the distances to
these galaxies through the period-luminosity relation for the Cepheid
stars.  The observations were executed as scheduled, and no anomalies were
noted.

   1.12 Completed Two Sets of NIC/2/3 7812 (NICMOS Modified Short One Orbit
Parallel)

       The Near Infrared Camera (Cameras Two and Three) was used to obtain
"JH" imaging of sky regions when another instrument is prime.  Two dither
positions are obtained for each filter.  The observations were completed as
scheduled, and no anomalies were reported.

   1.13 Completed STIS/CCD 7783 (STIS Parallel Science)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations taken in parallel with the prime science.  The observations
were completed, and no problems were reported.
