1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and
       Spiral Galaxies: A PC Snapshot Imaging Survey)

       The WF/PC-2 was used to make observations of the core regions of
       galaxies NGC-4818, NGC-1313, NGC-1515, and NGC-949 to provide
       statistics on the nuclear cups, stellar condensations, and inner
       stellar disks and dust lanes. The observations were executed as
       scheduled, and no anomalies were noted.

   1.2 Completed WF/PC-2 5562 (Cycle 4 Calibration: Internal Monitor 3:
       Darks)

       The WF/PC-2 was used to obtain several 30-minute long, dark 
exposures
       to provide ongoing calibration of the CCD dark current and to 
monitor
       and characterize the evolution of hot pixels. The observations were
       executed as scheduled, and no anomalies were noted.

   1.3 Completed FGS 5174 (Astrometric Companion Search - Cycle 4)

       FGS #3 was used to make astrometric observations of the possible
       binary dwarf star W1062 to look for an astrometric unseen low mass
       companion. The OSS monitored the observations and assessed the data
       quality. No anomalies were noted.

   1.4 Completed WF/PC-2 5663 (Cycle 4 Photometric Calibration Monitor 1:
       UV/OPT STD)

       The WF/PC-2 was used to make observations of globular cluster 
NGC-6752
       with various filters in order to check the photometric calibration 
of
       the WF/PC-2. The observations were completed as planned, and no
       anomalies were reported.

   1.5 Completed Two Sets of FOS/BL 5346 (Fundamental Evolutionary
       Parameters of B-Supergiants in the Post Main)

       The FOS (Blue Side) was utilized to look at the predicted gap in the
       H-R diagrams of SK-69D43 and SK-67D14 to see if they are filled with
       early B supergiants.  The instrument will obtain high S/N spectral
       data of four early B supergiants in the LMC to discriminate between
       various evolutionary scenarios and to constrain new stellar 
evolution
       scenarios.  There were no reported operational errors.

   1.6 Completed WF/PC-2 5584 (Parallel High Resolution Imaging of Diffuse
       Objects in the LMC)

       The WF/PC-2 was used to observe diffuse object LMC-LM1-8.  Of
       particular interest were H II regions, planetary nebulae, SNRs,
       supershells, and proto-stellar and maser regions.  The observation
       completed normally with report of any errors.

   1.7 Completed WF/PC-2 5397 (Determination of the Extragalatic Distance
       Scale: Cycle 4 High)

       The WF/PC-2 was used to make images of galaxy NGC-925 to be used
       in measuring the periods of Cepheid variable stars within the
       galaxies. One recentering event which lasted for a total of four
       seconds was reported, but no other anomalies were noted.

   1.8 Completed WF/PC-2 5571 (Cycle 4 Calibration: Earth Flats, Small Set)

       The WF/PC-2 was used to make several ultraviolet and narrow-band 
filter
       Earth flat calibration observations to correct for the telescope's
       illumination pattern. The observations were completed as planned, 
and
       no problems were reported.

   1.9 Completed Four Sets of FOS/BL 5444 (A UV Spectral Library of Metal-
       Poor Massive Stars)

       The FOS (Blue Side) was used for a snapshot program to obtain UV
       spectra of NS60-70, AV61, NS69-70, and AV14, all metal-poor stars
       in the LMC.  It will be useful for stellar atmosphere and stellar
       evolution studies.  The observations completed without incident.

   1.10 Completed WF/PC-2 5560 (Cycle 4 Calibration: Internal Monitor 1)

       The WF/PC-2 was used to make several internal bias, K-Spot, and flat
       calibration observations to monitor the CCD camera electronics, the
       optical alignment, and to check for contamination. The observations
       were completed as planned, and no anomalies were noted.

   1.11 Completed WF/PC-2 5751 (Understanding the Geminga (1E0630+178)
       Optical Counterpart Cycle 4 - H)

       The WF/FC-2 was used to obtain images of 1E060+178, the optical
       counterpart of neutron star GEMINGA.  The images will be used to
       determine the parallax of the target to get an estimate of its
       distance.  The observation was completed as planned, with no
       reported problems.

   1.12 Completed Two Sets of WF/PC-2 5568 (Cycle 4 Calibration: Decon)

       The WF/PC-2 was used to make an internal flat field calibration
       observation using the VIS lamp and the internal source as part of a
       decontamination operation. The observations were completed as 
planned,
       and no problems were reported.

   1.13 Completed Two Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR
       Radio Galaxies)

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C231.1
       as part of a continuum survey and to study the galaxy's morphology. 
The
       observations were executed as scheduled, and no anomalies were 
noted.

   1.14 Completed WF/PC-2 5753 (The Supernova Intensive Study)

       This proposal is part of a continuing project to study the
       development of supernovae and their circumstellar matter.  In this
       case, LMC-SN1987A was observed.  The observation completed normally,
       and there were no reported problems.

   1.15 Completed FGS 5134 (Extragalactic Astrometry and Astrophysics
       FT12-23)

       The FGSs were used to make astrometric observations of five 
different
       stars to tie the HIPPARCOS and extragalactic reference frames 
together.
       The targets in this set of observations were successfully acquired 
and
       observed. The observations were reported to be nominal.

   1.16 Completed FOC/96 5148 (A Search for Massive Stars in Giant III
       Regions in M31)

       The FOC/f96 observed BA379, a HII region of various metallicities in
       M31.  Color magnitude diagrams will be constructed for the massive
       stars within the region, and the upper mass cutoff will be studied,
       adding to the understanding of star formation.  The observation was
       completed with no reported problems.

   1.17 Completed WF/PC-2 5092 (Low Latitude Parallel Program)

       The WF/PC-2 was used to make observations taken in parallel with the
       prime science observations. This is part of a survey to take 
pictures
       of a large number of fields within 30 degrees of the galactic plane. 
The
       observations were completed as planned, and no problems were 
reported.

   1.18 Completed FOS/RD 5532 (Dark Monitoring)

       The Faint Object Spectrograph (Red Side) was used to monitor
       the instrument's background (dark) images. The observations were
       executed as scheduled, and on anomalies were noted.

   1.19 Completed FOS/RD 5631 (A New Size Constraint on Lyman Alpha Clouds)

       The FOS (Red Side) was utilized to view LB9605 to observe a pair of
       quasars separated by about one arcsecond, and one member of a second
       pair, with the expectation that constraints can be put on the scale
       of the absorbers which produce spectral lines in the Lyman Alpha
       forest.  One recentering event occurred, and the FOS continued
       to expose during the event.  No other problems were reported.

   1.20 Completed FOS/BL 5530 (Location of Spectra and Aperture)

       The Faint Object Spectrograph (Blue Side) was used to make Y-base 
maps
       of the FOS detectors using internal lamps. The purpose is to 
determine
       the location of the spectra on the diodes. The observations were
       executed as scheduled, and no anomalies were noted.

   1.21 Completed FGS 5135 (Extragalactic Astrometry and Astrophysics
       FT0-11)

       The FGSs were used to make astrometric observations to obtain data
       needed to measure the HIPPARCOS reference frame with respect to the
       extragalactic reference frame. The observations were executed as
       scheduled, and no anomalies were noted.

   1.22 Completed WF/PC-2 5091 (High Latitude Parallel Program)

       reported.

   1.23 Completed WF/PC-2 5114 (Stellar Formation and Evolution (WC14))

       The WF/PC-2 was used to make multi-color observations of object 
R136.
       The structure of the HH object will be determined on smaller scales
       than is possible from ground based observations. The observations
       were completed as planned, and no problems were reported.

   1.24 Completed HRS/1 5671 (Dark Noise Monitor - Cycle 4)

       The High Resolution Spectrograph (Side One) was used to make dark
       calibration images. These were strictly internal tests for routine
       monitoring of detector dark noise. The observations were executed as
       scheduled, and no anomalies were noted.
