1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOC/96 5526 (UV Throughput Monitoring - Cycle 4)

       The Faint Object Camera (f/96) was used to make calibration
       observations of ultraviolet standard star BPM16274, to monitor the
       ultraviolet throughput of the HST-FOC. The observations were
       executed as scheduled, and no anomalies were noted.

   1.2 Completed WF/PC-2 5370 (Medium Deep Survey: Cycle 4 Medium High
       Galactic Latitude - CR-Split)

       The WF/PC-2 was used in parallel with the prime science observations
       to make high galactic latitude observations as part of a medium-deep
       sky survey. The observations were completed as planned, and no
       problems were reported.

   1.3 Completed Two Sets of WF/PC-2 5430 (Imaging the UV Stars in M32 and
       NGC 205: Cycle 4 Medium)

       The WF/PC-2 was used to obtain images of the galaxies NGC-221 (M32)
       and NGC-205, which are satellite galaxies of the Andromeda galaxy
       (M31).  The images will be used to search for UV bright stars, the
       brightest of which have a S/N of 10-50.  In turn, the images will
       determine the colors and luminosities of the stars helping to
       understand the source of UV fluxes in galaxies. A total of four
       recentering events were reported. Two recentering events on object
       NGC-221 were reported for a total of nine seconds, and two
       recentering events on object NGC-205 were reported for a total of
       six seconds

   1.4 Completed Three Sets of WF/PC-2 5571 (Cycle 4 Calibration: Earth
       Flats, Smaller 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.

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

       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.

   1.6 Completed Two Sets of WF/PC-2 5655 (Cycle 4 Calibration: Internal
       Monitor 2: Flats)

       The WF/PC-2 was used to make both dark and visual flats. The
       observations were completed as planned, and no problems were 
reported.

   1.7 Completed Three Sets of 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.

   1.8 Completed Three Sets of WF/PC-2 5479 (Subarcsecond Structure in
       Nearby AGNs)

       The WF/PC-2 was used to make snapshot observations of the nearby
       active galactic nuclei of MARK917, MARK918, and UGC12138 to study
       the interactions between the central engine, the stars, and the
       interstellar matter in the AGN. The observations were executed as
       scheduled, and no anomalies were noted.

   1.9 Completed FOS/RD 5530 (Location of Spectra and Aperture)

       The Faint Object Spectrograph (Red 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.

   1.10 Completed FOC/96 5341 (High Resolution Imaging of Saturn's UV
       Aurora: Cycle 4 Medium)

       The FOC/f96 was used to observe Saturn in the UV to look for auroral
       emission at the north pole.  Images were obtained over one complete
       rotation of the planet (eight HST orbits) so that the brightness,
       morphology, and temporal variations of the aurora could be studied,
       a phenomenon already noticed by the Voyager UVS.  The observations
       completed without incident.

   1.11 Completed WF/PC-2 5464 (A Study of the AGB in Local Group Bulge
       Populations)

       The WF/PC-2 was used to make observations of the stellar bulge in
       galaxy NGC-224-1 to make a survey of its stellar population. The
       observations were completed as expected, and no problems were
       reported.

   1.12 Completed WF/PC-2 5570 (Cycle 4 Calibrations: Earth Flats, Large
       Set)

       The WF/PC-2 was used to make a set of Earth flat calibration images
       using different filters in order to construct high quality flat
       fields of the OTA illumination pattern. The observations were
       executed as scheduled, and no anomalies were noted.
