PERIOD COVERED:  0000Z (UTC) 12/15/97 - 0000Z (UTC) 12/16/97

Daily Status Report as of 350/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 7620 (WF/PC-2 Cycle 7 Standard Darks)

       The WF/PC-2 was used to make a series of Cycle 7 standard dark
calibration images.  This dark calibration program obtains dark frames
every week in order to provide data for the ongoing calibration of the CCD
dark current rate, and to monitor and characterize the evolution of hot
pixels.  The observations were executed as scheduled, and no anomalies were
noted.

   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 Four 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 Two Sets of STIS/MA2 7604 (Cycle 7 MAMA Dark Measurements)

       The Space Telescope Imaging Spectrograph (MA2) was used to make MAMA
dark measurements.  These darks will be used in later image reductions and
also trended over the instrument's lifetime as an indicator of the
detector's degradation or damage.  The observations were completed as
scheduled, and no problems were reported.

   1.5 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
observation was also taken.  All observations were executed as scheduled,
and no anomalies were noted.

   1.6 Completed WF/PC-2 7202 (The WF/PC-2 B Band Parallel Survey: A
Systematic and Synoptic Study of Galaxy Formation and Evolution - Short
Orbit Case)

       The WF/PC-2 was used to make observations as part of a B-Band survey
to make synoptic study of galaxy formation and evolution.  These
observations were taken in parallel with the prime science observations.
They were completed as planned, and no anomalies were reported.

   1.7 Completed NIC/1/2 7238 (High Resolution IRIS of the Centers of the
Nearest Interstellar Matter)

       The Near Infrared Camera (Cameras One and Two) was used to reveal
the structure of molecular filaments and condensations of object Crab-FK10
to obtain a series of narrow-band images in H_2 and [Fe II] of both
filaments, FK6 and FK10 {Fesen & Kirshner 1982}.  Images in He I
{F108N/F113N} will also be of interest.  Parallel observations with the
other NICMOS cameras will yield valuable information on line emission and
polarization at other selected positions in/near these filaments.  The
observations completed as planned with no reported problems.

   1.8 Completed WF/PC-2 6934 (WF/PC-2 Cycle 6 Photometric Zero-Point)

       The WF/PC-2 was used to make observations of standard star Rubin149
in order to complete a zero-point calibration observation.  The purpose of
this program is to verify synthetic zero-point of the WF/PC-2 filters.  The
observations were executed as scheduled, and no anomalies were noted.

   1.9 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.

   1.10 Completed NIC/1/2 7258 (The Nature of the Compact Infrared Core
Sources in Powerful FR II Radio Galaxies)

       The Near Infrared Camera (Cameras One and Two) was used to make
observations of the compact infrared nuclear core region of the powerful
radio galaxy 3C405.  It is hoped that these observations will provide some
of the most compelling evidence for the idea that all powerful radio
galaxies contain luminous quasars which are hidden from our direct view by
obscuring torii.  The observations were completed as planned, and no
anomalies were reported.

   1.11 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.  The observations were completed as planned, and no problems
were reported.

   1.12 Completed Two 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.

   2.3 Operations Notes:

       The STIS MCE reset on MAMA1, with low voltage on and outside the
SAA, at 349/105102Z.  HSTAR 6273 was written.  The error log was dumped.
Recovery of the MAMA will be accomplished via the SMS at the time of the
next MAMA1 high voltage on, 353/191637Z.
