PERIOD COVERED:  0000Z (UTC) 12/17/97 - 0000Z (UTC) 12/18/97

Daily Status Report as of 352/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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.

   1.2 Completed Two Sets of WF/PC-2 7612 (Infrared Imaging of 3CR Radio
Galaxies)

       The WF/PC-2 was used to make infrared observations of the radio
galaxy 3C342 to look for an infrared image counterpart to the radio image.
A dark calibration image was also taken.  The observations were executed as
scheduled, and no anomalies were noted.

   1.3 Completed STIS/CCD 7462 (Velocity Structure in High Redshift Galaxies)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the high redshift galaxy E-0050-275 in order to study its
velocity structure and to make imaging spectrographic observations of its
recently-discovered optical Einstein ring.  A wavelength calibration
observations was also taken.  The observations were executed as scheduled,
and no anomalies were noted.

   1.4 Completed WF/PC-2 6609 (The WF/PC-2 B-Band Parallel Survey: A
Systematic and Synoptic Study )

       The WF/PC-2 was used to make B-Band survey observations in parallel
with the prime science observations.  A total of 216 exposures will be
taken over a period of time to make a statistical study of the formation
and evolution of the galaxies.  The observations were executed as
scheduled, and no anomalies were noted.

   1.5 Completed FGS 6875 (Parallax of Delta Cephei)

       The Fine Guidance Sensors were used to make astrometric observations
of the Cephied class variable star Delta Cephei.  Delta Cephei is a
classical Cepheid variable, whose trignometric parallax is presently known
to around 30%.  HST observation shave the potential to reduce this
uncertainty to 15%.  The observations were completed as planned, and no
anomalies were reported.

   1.6 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 observations were
completed as planned, and no problems were reported.

   1.7 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.

   1.8 Completed NIC/1 7344 (Witnessing the Birth of Radio Galaxies:
WF/PC-2 & NICMOS Observations of CSOs)

       The Near Infrared Camera (Camera One) was used to make observational
images of the cores of bright, nearby galaxy  (Compact Symmetric Objects)
CSO 4C31.4 in order to try to witness the birth of a radio galaxy.  Only
HST can image these galaxies at the same size scale of the CSO itself, also
allowing us to search for nuclear structures aligned with the radio source
in this formative stage.  The observations were completed as planned, and
no anomalies were reported.

   1.9 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.

   1.10 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 NGC-1831 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 NIC/1/2/3 7608 (NICMOS Focus Monitoring)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
determine and monitor the optimal focus and tilt settings for all three
NICMOS cameras.  This proposal is built to run NIC1/2/3 sweeps on a 2-week
basis.  The observations completed without incident with no reported
anomalies.

   1.13 Completed NIC/2 7331 (Near-IR Properties of the Bulges of Spiral
Galaxies)

       The Near Infrared Camera (Camera Two) was used to make infrared
observations of the bulge in spiral galaxy NGC-7421.  Near-IR data at HST
resolution are essential for correcting for the effect of dust and will
enable us to derive robust nuclear properties for the sample.  The
observations were executed as scheduled, and no anomalies were noted.

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

       The Near Infrared Camera (Cameras Two and Three) was used to make
deep NICMOS observations of galactic cluster Abell-2199 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.
