1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/BL 5351 (Properties of Intermediate Redshift Galactic
       Disks Causing Damped Lyman-Alpha)

       The WF/PC-2 was used to make observations to study the diffuse
       material at intermediate redshifts that is identified by absorbing
       Lyman-Alpha spectrum from quasar 3C196.0. The observations were
       executed as scheduled, and no anomalies were noted.

   1.2 Completed Two Sets of WF/PC-2 5369 (HST Medium Deep Survey: Cycle 4
       Medium High Galactic Latitude)

       The WF/PC-2 made a series of observations of high latitude objects
       as part of a medium deep sky survey. The observations were taken in
       parallel with other prime science observations. WF/PC-2 observation
       #188 encountered a science data loss (33 packets) at 289/0317Z. The
       Tape Recorder Usage Log (.RUL) reported 1125 seconds (18.75 Minutes)
       on Science Tape Recorder #1. Only 17 minutes of playback had been
       scheduled.

   1.3 Completed Two 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.

   1.4 Completed WF/PC-2 5353 (Low Mass Binaries in the Hyades: Cycle 4 
High)

       The WF/PC-2 was used to make images of the low-mass, late M-Class
       dwarf star RHY403 which are located in the Hyades cluster. Some of
       the companion stars may be brown dwarfs. The observations were
       completed as scheduled, and no problems were reported.

   1.5 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 galaxies
       3C268.7 and 3C17.0 as part of a continuum survey and to study the
       galaxy's morphology. The observations were executed as scheduled,
       and no anomalies were noted.

   1.6 Completed Four 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 UM105, UM319, MARK533 and MARK573 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.

   1.7 Completed WF/PC-2 5453 (Deep Imaging of the Giant Luminous Arcs in
       CL0024+16: Cycle 4 Medium)

       The WF/PC-2 was used to make observations of the rich cluster of
       galaxies known as CL0024+16 which contains several luminous arcs,
       which are presumably caused by gravitational lensing of a background
       galaxy. The observations were executed as scheduled, and no
       anomalies were noted.

   1.8 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.

   1.9 Completed Six Sets of FOS/RD 5535 (Cycle 4 Internal Wavelength
       Calibration)

       The Faint Object Spectrograph was used to make internal calibration
       observations to monitor the stability of the wavelength scale for
       different gratings. During one set of observations at 289/1309Z an
       FOS speed check counter error was detected, however, no status
       buffer error message was received. No other anomalies were noted.

       slew to the GHRS LSA for observations. Standard target object AV207
       and AV451 was used. The observations were executed as scheduled, and
       no anomalies were noted.

   1.11 Completed WF/PC-2 5584 (Parallel High Resolution Imaging of Diffuse
       Objects in the Magellanic Cloud)

       The WF/PC-2 was used to observe diffuse object SMC-N70.  Of
       particular interest were H II regions, planetary nebulae, SNRs,
       supershells, and proto-stellar and maser regions. The observation
       completed normally with no report of any errors.

       Galactic Reference Frame)

       The Fine Guidance Sensors were used to to make astrometric
       observations of several stars (i.e., 0716+714IN and 0316+413IN) to
       help tie the HIPPARCOS and extragalactic reference frames
       together. The observations were completed as scheduled, and no
       anomalies were reported.

   1.17 Completed Two Sets of WF/PC-2 5370 (HST Medium Deep Survey: Cycle
       4 Medium Low Galactic Latitude - CR Split)

       The WF/PC-2 was used in parallel with the prime science observations

       is known to have ultraviolet bright, low-luminosity, active galactic
       nuclei. The observations were completed as planned, and no problems
       were reported.

   1.19 Completed FGS 5135 (Extragalactic Astrometry and Astrophysics)

       galaxy/quasar DHM0054-28 to search for other nearby galaxies that
       may be at the same distance. The observations were completed as
       planned, and no problems were reported.

   1.21 Completed WF/PC-2 5410 (Shock Morphology in Star-Forming Ring
       Galaxies)

       The WF/PC-2 was used to obtain images of two ring-shaped galaxies,
       probably caused by collision with another galaxy.  The observations
       were completed with no reported problems.
