1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WFC 4713 (WF/PC Cycle 2 Calibration: Internal 
       Delta flats)

       The Wide Field Camera was used to make two internal delta flat
       observations. These observations will be used for the restoration of
       Earth flat images, which were altered due to changes in quantum
       efficiency which occurred after WFPC decontamination operations.
       Both images were reported to look fine. 

   1.2 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.3 completed WFC 4105 (HST Medium Deep Survey: cycle 1 High Latitude)

       The Wide Field Camera was used to make one medium-deep high latitude
       sky survey observation in parallel with the prime science
       observation. The observation was reported to look okay. 

   1.4 Completed Two Sets of FOC/96 4804 (UV Imaging of Nearby Galaxies with 
       FOC/96)

       The Faint Object Camera was used to make two ultraviolet snapshot
       images of nearby galaxy UGC-8334. Each observation was a ten minute
       exposure, and used filter F220W. The images were reported to look
       excellent. 

   1.5 Completed WFC 4719 (Morphology of Galaxies in cluster at Z= 0.5 - 
       Cycle 2 DD Program)

       The Wide Field Camera was used to make four observations of Abell
       cluster of galaxies (CL0939+4713) to study their morphology. The
       observations were received and displayed in the OSS. They were
       reported to be okay. 

   1.6 Completed FOC/96 4821 (Magellanic Cloud Planetary Nebulae: Cycle 3 
       Med)

       The Faint Object Camera (f/96) was used with filter F501N to make
       one high resolution observations of the planetary nebula SMC-L305
       which is located in the Small Magellanic Cloud. This is to determine
       its mass and age. The observations were received and displayed. They
       were reported to look okay. 

   1.7 Completed FOC/96 3801 (Search For QSOs Suitable for Subsequent 
       Observation of Helium II)

       The Faint Object Camera (f/96) was used to make one observation of
       quasar 1548+4637 to measure its ultraviolet flux levels, to find out
       if this object has sufficient flux levels for subsequent
       observations using the HRS and FOS. The observations was received
       and displayed. No anomalies were noted. 

   1.8 Completed WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal 
       Monitor)

       Both the Wide Field Camera and the Planetary Camera were used to
       make internal flat observations using filter F555W to check for
       daisies and measles (i.e., forms of contamination). The observations
       were executed as scheduled, and no problems were reported. 

   1.9 Completed PC 4140 (WF/PC Cycle 2 Calibration: Rapid Internal 
       Monitor - Part 2)

       The Planetary Camera was used to make internal flat observations to
       check for new forms of contamination, and the possible return of
       quantum efficiency hysteresis. The observations were monitored in
       the OSS. The data quality was assessed, and no problems were
       reported. 

   1.10 Completed WFC 4770 (WF/PC Cycle 2 Calibration: Internal Delta Flats)

       The Wide Field Camera was used to make a bias and a dark calibration
       observations to be used for routine calibration. The observations
       were executed as scheduled, and no problems were reported. 

   1.11 Completed GHRS/2 3737 (The Onset of Chromospheric Activity)

       The High Resolution Spectrograph was used to make high resolution
       spectral observations of Carbon II resonance line (1335 A0) of A
       class star HD97603. The observation was monitored in the OSS. The
       data quality was assessed, and no problems were reported. 

   1.12 Completed FOS/BL 4054 (Probing the Nuclear Regions of Seyfert Galaxy 
        NGC-5548)

       The Faint Object Spectrograph was used to make spectral observations
       of the Seyfert galaxy NGC-5548 to study the time variability in its
       continuum, and the emission lines of Carbon IV and Helium II. The
       observations were executed as scheduled, and no problems were
       reported. 

   1.13 Completed WFC 3917 (HST Medium Deep Survey: Cycle 2 Part 1)

       The Wide Field Camera was used to make some high latitude sky survey
       images taken in parallel with the prime science observations. The
       observations were executed as scheduled, and no problems were
       reported.
