PERIOD COVERED:  0000Z (UTC) 01/15/97 - 0000Z (UTC) 01/16/97

Daily Status Report as of 016/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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.

   1.2 Completed FOS/RD 7204 (Pre-Perihelion Observations of the =
International Rosetta Mission Target)

       The Faint Object Spectrograph (Red Side) was used to make =
pre-perihelion, ultraviolet, spectrographic observations Comet Wirtanen =
(aka, comet 46/P) as part of a target viewing for the International =
Rosetta Mission which is scheduled to be launched in the year 2003.  The =
observations were completed as planned, and no anomalies were reported. 

  1.3 Completed FOS/RD 6487 (Spectroscopy of the Inner Satellites of =
Uranus)

       The Faint Object Spectrograph (Red Side) was used to make prism =
spectrographic observations of the star HD30246 (which is currently near =
Uranus).  This is part of a pre-study of Uranus' inner moons Miranda, =
Puck, Portia and Juliet.  Near the beginning of this proposal, a guide =
star acquisition failed to fine lock on FGS #3 only.  HSTAR 5878 was =
written.  Otherwise, the observations completed as planned, and no =
further problems were reported.

   1.4 Completed WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were =
reported.

   1.5 Completed FOS/RD 6914 (FOS Cycle 6: Location of Spectra and =
Wavelength Calibration - Red Side)

       The Faint Object Spectrograph (Red Side) was used to make both a =
TALED and a wavelength calibration image.  All observations were made =
using internal light sources.  This proposal will be executed a total of =
12 time during cycle 6 (i.e., once per month).  The observations were =
executed as scheduled, and no anomalies were noted.

   1.6 Completed FGS 6047 (Calibrating the Mass Luminosity Relation at =
the End of the Main Sequence)

       The FGSs were used to make astrometric observations of the =
binarystars GL494A and B as part of a study to determine its mass =
luminosity relationship.  The purpose is to measure the precise parallax =
and relative orbit of its faint companion.  The observations were =
completed as planned, and no problems were reported.

   1.7 Completed WF/PC-2 6906 (WF/PC-2 Cycle 6 Calibration: Internal =
Monitor-Visual Flats)

       The WF/PC-2 was used to make internal calibration visual flat =
images as part of the Cycle 6 internal monitoring of the instrument's =
operations.  This proposal defines the standard series of internal flat =
fields, which will be executed twice per month.  The observations were =
completed as planned, and no anomalies were reported.

   1.8 Completed FOS/BL 6781 (Soft X-Rays and the UV Spectra of a =
Complete QSO Sample)

       The Faint Object Spectrograph (Blue Side) was used to obtain =
ultraviolet spectra of the low-Z quasi-stellar object PG1001+054.  The =
ionization continuum of this object has been studied using the ROSAT =
satellite.  The strengths and line profiles of strong and weak =
ultraviolet emission and absorption lines and the ultraviolet continuum =
were studied.  The observations were completed as planned and no =
anomalies were reported.

   1.9 Completed Four Sets of 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.

   1.10 Completed Four Sets of WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: =
Earth Flats)

       The WF/PC-2 was used to make observations of the bright Earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 9
                                        Successful : 7

       HSTAR 5878 describes an acquisition at 015/1225Z which failed to =
fine lock backup on FGS #3 only.

       HSTAR 5879 describes another acquisition at 016/013554Z whiched =
failed to fine lock backup on FGS #1 only.  In this case the seven subsequ=
ent re-acquisitions failed in the same manner.

                          Scheduled Reacquisitions : 11
                                        Successful : 4
