1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Complete WFC 4929 (WF/PC Cycle 2: Improved Dark Calibration)

       The Planetary Camera was used to make two dark calibration images.
       The two exposures lasted 1200 seconds each, and the camera was
       pre-flashed before the observations. Both observations were
       monitored in the OSS, and no anomalies were reported. The science
       data still remains on the science tape recorder. 

   1.2 Complete FOC/96 5030 (F/96 Filter Photometric Calibrations)

       The Faint Object Camera (f/96) was used to make observations of
       standard star HZ-4 to make calibrations of various photometric
       filters. A total of 11 observations were taken. They were monitored
       (when possible), received, and displayed. They all were reported to
       be normal. 

   1.3 Complete WFC 5013 (WF/PC Cycle 3 Calibration: WFC Flats Narrow. 2)

       The Wide Field Camera was used to make two Earth flat calibration
       images to be used for flat fielding of WFC observations. The
       observations used the narrow band filters, both with and without
       neutral density filters. Both observations were received, and both
       were reported to be okay. 

   1.4 Uplink Updated Ephemeris Tables, Per MOSES 2871

   1.5 Complete PC 5014 (WF/PC 3 Calibration: PC Flats Narrow. 2)

       The Planetary Camera was used to make two standard Earth
       calibrations images for flat fielding of PC observations. Medium and
       narrow filters were used, with and without neutral density filters.
       The observations were executed as scheduled. One observations was
       reported to be partially saturated, and the other was normal. 

   1.6 Complete HSP/UV1/UV2/POL 5082 (X-Ray binaries Part 2 - Cycle 3 High) 

       The High Speed Photometer was used to make six photometric and
       polarimetric observations of X-Ray binary star HD153919 (aka,
       3U1700_37) to obtain more information about the structure and
       condition in the gas streams connecting the primary star to its
       neutron companion. All six observations were received and displayed
       in real-time. The target was reported to be well centered. 

   1.7 Complete HSP/UV2 4209 (Determination of the Masses and Densities of 
       Pluto and Charon - cycle 3)

       The High Speed Photometer was used to make calibration observations
       of standard star BD+75D325 to determine the instruments long term
       sensitivity of the IDT detectors. The observations were monitored in
       the OSS, and the data quality was assessed. No problems were
       reported. 

   1.8 Complete PC 4140 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor
       - Part 2) 

       The WFPC was used to make internal flat calibrations images to check
       for new forms of contamination (i.e., Daises and measles), and to
       check for the possible return of quantum efficiency hysteresis. The
       observations completed as scheduled, and no problems were reported. 

   1.9 Complete HSP/POL 4887 (X-Ray Binaries - AUG - Cycle 3 High) 

       The High Speed Photometer was used to make photometric and
       polarimetric observations of X-Ray binary star LMCX-3 to obtain more
       information about the structure and condition in the gas streams
       connecting the primary star to its neutron companion. The
       observations were executed as scheduled, and no problems were
       reported.
