1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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 for contamination. A total of ten images was
       taken. Some of the Bias exposures show a slight density gradient
       across the images, especially in CCD #3. The internal flats and
       K-spot exposures were normal.

   1.2 Completed GHRS/1 5373 (Excitation Processes for the Ultraviolet
       Dayglow of Jupiter: Cycle 4)

       The High Resolution Spectrograph (Side One) was used to make
       observations looking for molecular hydrogen emissions in the Jovian
       equatorial atmosphere. Four observations were executed as scheduled,
       and they were reported to look okay.

   1.3 Completed FGS 5333 (Linking the HIPPARCOS to the Extragalactic
       Reference Frame BR12-23, Part 2)

       The FGSs were used to obtain astrometric observations on several
       stars whose apparent positions lie near extragalactic objects. The
       astrometric observations were monitored while telemetry was
       available. Most of the observations appeared to succeed, but at
       least two of them ended with a Stop Flag being set.

   1.4 Completed WF/PC-2 5479 (Subarcsecond Structures in Nearby AGNs)

       The WF/PC-2 was used to make observations of galaxy NGC-5757. Two
       observations were received and displayed. They were reported to look
       fine.

   1.5 Completed WF/PC-2 5218 (Io's Interactions With the Jovian Plasma
       Torus)

       The WF/PC-2 was used to make observations as part of a proposal to
       study the Moon IO and its immediate vicinity. A total of 26
       observations were received and displayed. They were reported to all
       look okay.

   1.6 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 galaxy.
       Two images were received and displayed, and they were reported to
       look fine.

   1.7 Completed Three Sets of WF/PC-2 5481 (Ages for the Outermost
       Globular Clusters)

       The WF/PC-2 was used to make observations of a globular cluster 
known
       as NGC-2419-SO. A total of fifteen observations were executed.
       Thirteen of the observations were received and displayed, and they
       were reported to be okay. Two observations remain on the Science
       Tape Recorder, and will be analyzed later. No anomalies were noted.

   1.8 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-2683. The
       observations were executed as scheduled, and no anomalies were
       noted.

   1.9 Completed GHRS/2 5597 (GHRS ECH-B Sensitivity Calibration: Cycle 4)


       The High Resolution Spectrograph (Side Two) made observations of the
       standard star Mu-Columbae to help calibrate the sensitivity of the
       Echelle-B. The observations were executed as scheduled, and no
       anomalies were noted.

   1.10 Completed WF/PC-2 1070 (High Resolution Imaging of Radio Galaxies
       at Large Redshift)

       The WF/PC-2 was used to make deep images of radio galaxy 3C239. The
       observations were executed as scheduled, and no anomalies were
       noted.

   1.11 Completed WF/PC-2 5465 (WF/PC-2 Imaging of Two Galaxy Cluster at
       Z=1.2)

       The WF/PC-2 was used to make deep images of galaxy cluster 3C324 at
       Z=1.2. The observations were executed as scheduled, and no anomalies
       were noted.

   1.12 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earthflats,
       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. A total of eight images was
       received and displayed. Four exposures were reported to be okay, two
       were underexposed, and two were saturated.

   1.13 Completed FOS/RD 5579 (Cycle 4 Test: To Determine FOS Polarimetry
       Mode)

       The Faint Object Spectrograph (Red Side) was used to make internal
       calibration observations of its polarization capabilities.  The
       observations were executed as scheduled, and no anomalies were
       noted.

   1.14 Completed FGS 5510 (Mass Ratio Determination for Doubles with
       Substellar Mass Members)

       The Fine Guidance Sensors were used to make astrometric
       observations of binary star L722-22-00. The astrometric observations
       were monitored, and no problems were seen. The co-investigator was
       present to monitor the observations.

   1.15 Completed WF/PC-2 5370 (HST 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 executed as scheduled, and the
       observations still remain on Science Tape Recorder #3. They will be
       analyzed later. No anomalies were noted.

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

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C9.0
       as part of a continuum survey and to study the galaxy's morphology.
       The observations were executed as scheduled, and the observations
       still remain on Science Tape Recorder #3. They will be analyzed
       later. No anomalies were noted.
