PERIOD COVERED:  0000Z (UTC) 12/02/97 - 0000Z (UTC) 12/03/97

Daily Status Report as of 337/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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 third iteration of this proposal was affected by the first
acquisition failure described in 2.1.  Otherwise, the observations were
executed as scheduled, and no further anomalies were noted.

   1.2 Completed STIS/MA1 7575 (The He-II Gunn-Peterson Test)

       the Space Telescope Imaging Spectrograph (MA1) was used to make
observations of the quasar Q0302-0019 in order to conduct the Gunn-Peterson
Test.  A wavelength calibration observation was also taken.  The
observations were completed as scheduled, and no anomalies were noted.

   1.3 Completed Five 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.

   1.4 Completed Four Sets of WF/PC-2 7625 (WF/PC-2 Cycle 7 Earth Flats)

       The WF/PC-2 was used to make a series of Earth flat calibration
images.  These flat fields will allow mapping of the OTA illumination
pattern and will be used in conjunction with previous internal and external
flats to generate new pipeline superflats.  The observations were completed
as planned, and no anomalies were reported.

   1.5 Completed FGS 7493 (Calibrating the Mass-Luminosity Relation at the
End of the Main Sequence)

       The FGSs were used to make observations of GJ2005 in order to make
calibration observations of the mass-luninocity relation at the end of the
main sequence.  The study utilizes HST-FGS and infrared speckle imaging to
calibrate the mass-luminosity relation for stars less massive than 0.2
Msun, with special emphasis on objects near the stellar/brown dwarf border.
The observations were completed as scheduled, and no prblems were noted.

   1.6 Completed 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.

   1.7 Completed S/C 5582 (FOC/48 Monthly Activation (Camera Section Only):
Cycle 4)

        This proposal was executed as scheduled, and no anomalies were noted.

   1.8 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.

   1.9 Completed NIC/2 7228 (Imaging and Polarimetry of YSO'S)

       The Near Infrared Camera (Camera Two) was used to investigate the
young stellar object (YSO) FS-Tau with coronagraphic imaging, polarimetry,
and line imaging.  This proposal was affected by the first acquistion
failure described in 2.1  No further problems were reported.

   1.10 Completed Three 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 first and third
iterations of this proposal were affected by the two acquisition failures
described in 2.1  Otherwise, the observations were completed as planned,
and no further problems were reported.

   1.11 Completed WF/PC-2 6254 (GTO Pure Parallel Program - Cycle 5)

       The WF/PC-2 was use to make random long exposures of high galactic
fields taken in parallel with the prime science observations to obtain a
random sample of galaxies.  This proposal was affected by the first
acquisiton failure described in 2.1.  No further anomalies were noted.

   1.12 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.

   1.13 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 STIS/CCD 7636 (STIS Spectroscopic CCD Flatfielding)

       The Space Telescope Imaging Spectroscope (CCD) was used to make a
CCD flat field calibration observation in the spectrographic mode.  A bias
calibration was also taken.  The observations were completed as planned,
and no anomalies were reported.

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

       The Near Infrared Camera (Camera One) was used to make observations
of object 3C286 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.

   1.16 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 final three iterations of this proposal were
affected by the acquisition and re-acquisition failure described in 2.1.
Otherwise, the observations completed normally, and no further anomalies
were reported.

   1.17 Completed NIC/2 7171 (Stellar Distributions in Nearby Galaxy Nuclei)

       The Near Infrared Camera (Camera Two) was used to make observations
of the stellar distribution in nearby galaxies M31 and M32 which are in the
Local Group.  The nuclei of nearby galaxies which are suspected of
harboring black holes because of kinematic data and because of the presence
of nuclear radio sources will be imaged to search for abnormalities in the
stellar distribution.  The observations were completed as planned, and no
problems were reported.

   1.18 Completed NIC/1/2/3 7268 (Nuclear Brightness Profiles of Merger
Remnants; Do Mergers Form Ellipticals?)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the elliptical galaxy NGC-34.  Many elliptical
galaxies might have formed from mergers of disk galaxies.  Numerical
simulations yield elliptical-like remnants and observed merger remnants
have R^1/4 surface brightness profiles.  However, while the global
properties of merger remnants and ellipticals are similar, it is unknown
whether this is true for their nuclear properties as well.  This proposal
was affected by the second acquisiton failure described in 2.1  No further
anomalies were noted.

Proposals described in 1.0, 1.9, 1.10, and 1.11 were affected since the
take data flag remained down.

       Per HSTAR 6261, the guide star acquisition at 336/221233Z failed.
An ARU/PRT was prepared and uplinked; however, the following three
