PERIOD COVERED:  0000Z (UTC) 12/03/97 - 0000Z (UTC) 12/04/97

Daily Status Report as of 338/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Seven Sets of 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.

   1.2 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.

   1.3 Completed Three Sets of 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.

   1.4 Completed NIC/1 7451 (Gravitational Lensing by Damped Ly-Alpha
Absorbers)

       The Near Infrared Camera (Camera One) was used to make observations
of object 3C446 in order to study gravitational lensing in damped
Lyman-Alpha absorbers.  Damped Lyman-Alphas are thought to arise in the
disk of the progenitors of present-day spiral galaxies.  The observations
were completed as scheduled, and no problems were reported.

   1.5 Completed STIS/CCD 7635 (STIS CCD Hot Pixel Annealing)

       The Space Telescope Imaging Spectrograph (CCD) was used to test the
hot pixel annealing procedure.  The effectiveness of the CCD hot pixel
annealing process is assessed by measuring the dark current behavior before
and after annealing and by searching for any window contamination effects.
The observations were completed as planned, and no problems were reported.

   1.6 Completed NIC/2 7457 (Warm Molecular Hydrogen in Cluster Cooling
Flow Nebulae)

       The Near Infrared Camera (Camera Two) was used to make observations
of the emission-line nebula Abell-2597 in order to study warm molecular
hydrogen in a cluster cooling flow nebula.  The intracluster gas at the
centers of many clusters of galaxies can cool within a Hubble time,
prompting the suggestion that the ICM in these clusters cools and flows
towards the center, where it subsequently condenses.  The observations were
completed as planned, and no anomalies were reported.

   1.7 Completed Five Sets of STIS/CCD 7600 (STIS CCD Performance Monitor)

       The Space Telescope Imaging Telescope (CCD) was used to measure the
baseline performance and commandability of the CCD subsystem.  Only primary
amplifier D is used.  Bias, dark, and flat field exposures are taken in
order to measure read noise, dark current, CTE, and gain.  Numerous bias
frames are also taken to permit construction of "superbias" frames in which
the effects of read noise have been rendered negligible.  Dark exposures
are made outside the SAA.  The observations completed normally, and no
anomalies were reported.

   1.8 Completed Four Sets of STIS/CCD 7782 (STIS Non-Scripted Parallel
Archive Proposal - Half Orbit)

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

   1.9 Completed Two Sets of 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.  The
observations were executed as scheduled, and no problems were reported.

   1.10 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.

   1.11 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 H-11 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.

   1.12 Completed WF/PC-2 6619 (High Resolution Images of QSO Lyman-Alpha
Absorbing Galaxies)

       The WF/PC-2 was used to make several images of galaxy field (Field
1301) in order to obtain high resolution observations of the Lyman-Alpha
absorbing galaxies within this field-of-view. The purpose is to directly
identify the objects responsible for low and intermediate redshift QSO in
Lyman-Alpha systems.  The observations were executed as scheduled, and no
anomalies were noted.

   1.13 Completed 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.

   1.14 Completed 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.

   1.15 Completed NIC/1/2/3 7421 (The Relation Between Quasar Luminosity
and Host Galaxy Mass)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
obtain ground-based, near-infrared imaging of nearby quasar UM357 which has
indicated a relation between the luminosity of its nucleus and the luminous
mass of its host galaxy.  The observations completed as planned, with no
reported problems.

   1.16 Completed WF/PC-2 6659 (A Search For Superplanets Around Weak T-
Tauri Stars)

       The WF/PC-2 was used to make observations in the 1 micron band of
the T-Tauri class star HBC636 in order to search for superplanets.  Weak
T-Tauri class stars are thought to have dissipated their circumstellar
disks recently, possibly by forming planetary systems.  The observations
were completed as planned, and no anomalies were reported.

   1.17 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 M{max} 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.

   1.18 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.
