1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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. The
       observations were executed as scheduled, and the data remains on
       Science Tape Recorder #3. The data will be analyzed later. No
       anomalies were noted. 

   1.2 Completed GHRS/1 5541 (GHRS Side 1 Dark Noise Monitor: Cycle 4)

       The High Resolution Spectrograph (Side One) was used to make routine
       detector dark noise calibration observations. These were internal
       tests and did not require any special pointing of the telescope. The
       observations were executed as scheduled, and the data remains on
       Science Tape Recorder #3. No anomalies were noted. 

   1.3 Completed FOS/RD 5536 (Cycle 4 FOS Wavelength Calibration: 
       Internal/External Offsets)

       The Faint Object Spectrograph (Red Side) made both internal and
       external wavelength calibration observations. HD207757 was the
       external source. The observations were executed as scheduled, and
       the data remains on Science Tape Recorder #3. No anomalies were
       noted. 

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

        The WF/PC-2 was used to make both dark and visual flats. The
        observations were executed as scheduled, and the data remains on
        Science Tape Recorder #3. The data will be analyzed later. No
        anomalies were noted. 

   1.5 Completed WF/PC-2 5629 (WF/PC-2 Cycle 2 Photometric Calibration 
       Monitor: 4-Chip STD in F170W)

       The WF/PC-2 was used to make photometric calibration observations of
       the ultraviolet standard star GRW+70D582. The observations were
       executed as scheduled, and the data remains on Science tape Recorder
       #3. No anomalies were noted. 

   1.6 Completed Two Sets of WF/PC-2 5465 (WF/PC-2 Imaging of Two Galaxies 
       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. 

   1.7 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. 

   1.8 Completed Two Sets of 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. The observations were
       executed as scheduled, and no anomalies were noted.
