1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed 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. The observations
       were completed as scheduled, and no anomalies were noted.

   1.2 Completed 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 UGC-6100 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.

   1.3 Completed FOS/BL 5095 (Spectra at Lambda <3000 Angstroms for QSOs
       with Z~2 (FOS 3): Cycle 4)

       The FOS Blue Side microprocessor and low voltage were activated.  No
       real science observations were taken because the high voltage
       turn-on was delayed..

   1.4 Completed two Sets of WF/PC-2 5091 (GTO High Latitude Parallel
       Program: Cycle 4)

       The WF/PC-2 was used in parallel with the prime science observations
       to make high galactic latitude observations greater than +/-30
       degrees. The observations were executed as scheduled, and no
       problems were reported.

   1.5 Completed Two Sets of WF/PC-2 5562 (WF/PC-2 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.

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

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C86.0
       as part of a continuum survey and to study the galaxy's morphology.
       The observations were executed as scheduled, and no anomalies were
       noted.

   1.7 Completed WF/PC-2 5390 (Observations of the Abated Companion of an
       Eclipsing Pulsar)

       The WF/PC-2 was used to make observations of the eclipsing binary
       pulsar PSR1957+20 to obtain minimum light, in order to determine the
       temperature of the cool "backside" of the companion star. There was
       one guide star recentering event reported which lasted for a total
       of five seconds. No other anomalies were noted.

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

       The FOS Blue Side microprocessor and low voltage were activated. No
       real science observations were taken because the high voltage
       turn-on was delayed.

   1.9 Completed WF/PC-2 5384 (Resolved and Composite Properties of the
        Giant H II Regions of M-33)

       The WF/PC-2 was used to make observations of H II regions within
       galaxy M-33 known as M33-NEB1 and M33-NEB7. There were three guide
       star acquisition recentering events reported which lasted for a
       total of 17 seconds. No other anomalies were noted.

   1.10 Completed WF/PC-2 5560 (WF/PC-2 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 Two Sets of FGS 5135 (Extragalactic Astrometry and
       Astrophysics, FT0-11, Part 1 of Two)

       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. (Objects: 0134+329IN, 221-REF,
       222-REF, INCA221-9, 941-REF, 0537-441IN, 940-REF, 942-REF,

       scheduled, and no anomalies were noted.

   1.12 Completed Four Sets of WF/PC-2 5092 (GTO Low Latitude Parallel
       Program: Cycle 4)

       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.

   1.13 Completed three Sets of WF/PC-2 5655 (WF/PC-2 Cycle 4 Calibration:
       Internal Monitor. 2: Flats Part 2)

       reported.

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

       The WF/PC-2 was used to make observations of the core region of
       galaxy 0314-3542 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.

   1.15 Completed FGS 4884 (High Speed Astrometry: A Search for Astrometric
       Companions to Low Mass Stars)

       The FGSs were used to make observations of Barnard's star to look
       for astrometric companions (i.e., a Jupiter-sized companion). The
       observations were completed as planned, and no problems were
       reported.

   1.16 Completed WF/PC-2 5415 (The Distance to M-96 Galaxy Group: Cycle 4

       within the galaxy NGC-3368 which itself is located in the M-96
       galaxy cluster. This is to help determine the distance to this
       galactic group, and to improve the determination of the Hubble
       constant. The observations were completed as planned, and no
       anomalies were reported.

       observations of the nucleus of NGC-4151 to study the C IV, C II, and
       Si II lines. A wavelength calibration was also obtained. The
       observations were executed as scheduled, and no anomalies were
       noted.

   1.18 Completed WF/PC-2 5395 (High Spatial Resolution Imaging of the
        Pre-Main Sequence Binary Stars)

       The WF/PC-2 was used to make ultraviolet observations of pre-main
       sequence binary star V773TAU. The observations were executed as

       in the Taurus star forming region. The FGS data will provide the
       apparent orbits. The observations were executed as scheduled, and no
       anomalies were noted.

   1.21 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 High, High
       Galactic Latitude)

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

       dwarf (BCD) galaxy IZW18 (aka, One Zwicky 18) which is known to have
       a low abundance of heavy elements. The observations were executed as
       scheduled, and no anomalies were noted.

   1.23 Completed GHRS/1 5276 (GHRS Side 1 Detector Calibration : Cycle 4)

       The High Resolution Spectrograph was used to conduct a standard
       detector test that will be used as part of the routine calibration
       for the HRS. Dark and internal flat calibration observations were
       also obtained. The observations were completed as planned, and no
       anomalies were reported.

   1.24 Completed WF/PC-2 5511 (Detailed Study of 4C41.17, the Most Distant
       Galaxy: Cycle 4 Medium)

       The WF/PC-2 was used to make early acquisition images the galaxy
       4C41.17, which is the most distant known galaxy. This is to try to
       locate the knots which will be later observed with the FOS. The
       observations were completed as planned, and no problems were
       reported.

   1.25 Completed Two Sets of  FGS 5657 (Duplicity Among Hyades Stars:
       Cycle 4 High)
