PERIOD COVERED:  0000Z (UTC) 11/13/97 - 0000Z (UTC) 11/14/97

Daily Status Report as of 318/0000Z

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 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.

   1.3 Completed Four Sets of STIS/CCD 7601 (CCD Dark and Bias Monitor)

       The Space Telescope Imaging Spectrograph (CCD) was used to conduct
bias and dark monitoring.  Also, observations were made to track the growth
of hot pixels on the CCD in general and within the various target
acquisition apertures specifically.  The observations were completed as
planned, and no anomalies were reported.

   1.4 Completed NIC/2 7327 (Elliptical Galaxy Evolution at High Redshift:
IR Imaging of 60 Distant Clusters)

       The Near Infrared Camera (Camera Two) was used to make infrared
observations of high redshifted elliptical galaxies in galactic cluster
CL1335+464.  By measuring the structural properties of high redshift
cluster elliptical galaxies, it is hoped to resolve the controversy
regarding the age and formation history of bright cluster ellipticals.  The
observations were executed as scheduled, and no anomalies were noted.

   1.5 Completed NIC/1/2 7365 (Unscrambling the Near-Infrared Properties of
Young Planetary Nebulae)

       The Near Infrared Camera (Cameras One and Two) was used to make
observations of the young planetary nebula PK111-02D1.  Objects of this
class display a number of enigmatic features that have prevented a full
understanding of post-asymptotic giant branch stellar evolution.  The
observations were executed as scheduled, and no anomalies were noted.

   1.6 Completed WF/PC-2 7619 (WF/PC-2 Cycle 7 Decontamination)

       The WF/PC-2 was used to conduct a Cycle 7 decontamination procedure.
Ultraviolet-blocking contaminants are removed, and hot pixels cured, by
warming the CCDs to +20C for six hours.  A variety of internal images are
taken before and after the decontamination in order to verify its success
and to monitor the instrument health.  The procedures were conducted as
scheduled, and no problems were reported.

   1.7 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.

   1.8 Completed STIS/CCD/NIC/1/2 7566 (Demographics of Nuclear Black Holes)

       The Space Telescope Imaging Spectrograph (CCD), the Near Infrared
Camera (Cameras One, Two and Three) and the WF/PC-2 were all used to make
observations of normal galaxy NGC-1023 to try to detect a super massive
black hole.  A dark and wavelength calibration images were also taken.  The
observations were executed as scheduled, and no anomalies were noted.

   1.9 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 IC51.  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.  The observations were executed
as scheduled, and no anomalies were noted.

   1.10 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 the nearby quasar Markarian
876-CA which have indicated a relation between the luminosity of the
nucleus and the luminous mass of the host galaxy.  The observations
completed as planned, with no reported problems.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions:

                            Scheduled Acquisitions : 6
                                        Successful : 6

                          Scheduled Reacquisitions : 10
                                        Successful : 10

   2.2 FHST Updates:

                              Scheduled : 16
                             Successful : 15

       The update at 318/0948Z failed.

   2.3 Operations Notes:

       As described in HSTARs 6240 and 6241, there were occurrences of
Error Detection and Correction (EDAC) counts for SSR Storage Area 1 (SA1)
outside the SSR area (where such levels are expected) during a dump
operation.  The counts did correspond to the entrance into a level 1 South
Atlantic Anomaly (SAA) region.  EDAC SA1 errors also occurred at the end of
the dump which was not in a SAA, and also occurred at the beginning of the
next dump.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

       Continuation of normal science observations and calibrations.
