1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5565 (WF/PC-2 Cycle 4: Photometric Calibration
       Monitor: Fields)

       The WF/PC-2 was used to make photometric calibration observations by
       taking images of the large globular cluster Omega Centauri (aka,
       NGC-5139) to help determine astrometric and optical stability of the
       WF/PC-2. The OSS monitored the observations, and assessed the data
       quality. The images were reported to look okay.

   1.2 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 a 30-minute long, dark exposure
       to provide ongoing calibration of the CCD dark current and to
       monitor and characterize the evolution of hot pixels. The image was
       received and displayed in the OSS. The image was reported to look as
       expected.

   1.3 Completed GHRS/1 5438 (Io's Atmosphere: UV Spectroscopy of Neutral
       and Molecular Components)

       The High Resolution Spectrograph (Side One) was used to make far
       ultraviolet spectrographic observations of Jupiter's moon Io. All
       the acquisitions and re-acquisitions achieved fine lock, and the
       images were adequately centered in the subsequent observations. No
       anomalies were noted.

   1.4 Completed WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral Galaxies)

       The WF/PC-2 was used to make observations of galaxy NGC-4303. The
       observations were executed as scheduled, and the science data
       remains of Science Tape Recorder #3. It will be analyzed later. No
       anomalies were noted.

   1.5 Completed GHRS/2 5093 (Composition of Gas in Individual Interstellar
       Clouds: Cycle 4 Observation)

       The High Resolution Spectrograph (Side Two) was used to obtain the
       spectra of a the early type star HD219188 to study interstellar
       clouds which lie along the line of sight to the star. Four
      observations were received in real time. These onboard target
       acquisitions were successful. More data still remains on Science
       Tape Recorder #3, and will be analyzed later.

   1.6 Completed WF/PC-2 5655 (WF/PC-2 Cycle  4 Calibration: Internal
       Monitor. 2: Flats Part 2)

        The WF/PC-2 was used to make an ultraviolet flat. The observation
        was executed as scheduled, and the data still remains on Science
        Tape Recorder #3. It will be analyzed later.

   1.7 Compleed WF/PC-2 5560 (WF/PC-2 Cycle 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 executed as scheduled, and the data remains on both Science
       Tape Recorders 1 and 3. The data will be analyzed later.

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

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C222.0
       as part of a continuum survey and to study the galaxy's morphology.
       The observations were executed as scheuled, and the data remains on
       Science Tape Recorder #1. The data will be analyzed later.

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

       The WF/PC-2 was used to make images of galaxy NGC-4321 to be used in
       measuring the periods of Cepheid variable stars within the galaxies.
       The observations were executed as scheduled, and no anomalies were
       noted.

   1.10 Completed WF/PC-2 5216 (Io's Volcanic Surface and Atmosphere)

       The WF/PC-2 was used to make ultraviolet images images of the
       trailing hemisphere of Jupiter's moon Io. The observations were
       executed as scheduled, and no anomalies were noted.
