1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 3880 (Curcumstellar and Interstellar Absorption 
       Lines in Planetary Nebulae)

       The High Resolution Spectrograph was used to make nine spectral
       observations of the planetary nebula IC3568 trying to obtain
       information about the mass of the neutral material surrounding the
       central star. All nine observations were reported to look very good. 
 
   1.2 Completed FGS 4724 (Seven Point of Light Cycle 2 Calibration)

       The Astrometric FGS was used to calibrate the single star
       interferometric fringe pattern at seven separate points in the
       central region. The observations were monitored in the OSS, and no
       problems were seen in the Telemetry. 

   1.3 Completed GHRS/2 3496 (An Ultraviolet Atlas of Sirius: Constraining
       Model Stellar Atmospheres) 

       The High Resolution Spectrograph was used to obtain ultraviolet
       spectra of the star Sirius (aka, HD48915) in Canis Major. Two
       observations were received in real time. The target was found in the
       second map of the 3x3 return to brightest spiral search, with the
       target search flux of 94,800. The field map showed the target
       slightly off center before the balance and peakup were done. 

   1.4 Completed WFC 4207 (WF/PC cycle 2 Calibration: photometric Calibration 
       Monitor)

       The Wide Field Camera was used to make ultraviolet observations of
       standard star BD+75D325 to monitor the camera's flux throughput. The
       observations were made in fine lock. The observations were monitored
       in the OSS, and the data quality was assessed. No problems were
       reported. 

   1.5 Completed Three Sets of FOS/BL 4054 (Probing The Nuclear Regions of
       the Seyfert Galaxy NGC-5548) 

       The Faint Object Spectrograph was used to make spectral observations
       of the nuclear regions of Seyfert galaxy NGC5548 to study time
       variations in its continuum, and emissions in Helium II and Carbon
       IV. The observations were reported to look good. 
 
   1.6 Completed Two Set of WFC 4381 (HST Medium-Deep Survey - Cycle 3)

       The  Wide Field Camera was used to make two high latitude
       medium-deep sky survey observations taken in parallel with the prime
       science observations. The first observations was reported to be
       satisfactory, and the second was reported to be excellent. 

   1.7 Completed FOC/96 4804 (UV Imaging of Nearby Galaxies with the FOC/96)

       The Faint Object Camera (f/96) was used to make two snapshot images
       of nearby galaxy UGC-7231. Each exposure was ten minutes long, and
       used filter F220W. The first image was examined, and no anomalies
       were reported. The second observations was reported to be blank. 

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

       Both the Planetary Camera and the Wide Field Camera were used to
       make internal delta flat observations to check for new forms of
       contamination (i.e., daisies and Measles), and the possible return
       of quantum efficiency hysteresis. Both observations were reported to
       be normal internal flats. 

   1.9 Completed PC 4712 (WF/PC Cycle 2 Calibration: Measles Monitor)

       The Planetary Camera was used to make three Earth flat images both
       with and without filter F122M. One observation was underexposed, one
       was overexposed, and the last was reported to be okay. 

   1.10 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.11 Completed GHRS/2 3513 (Non-Lte Analysis of the Population II 
        Post-AGB Stars ROB 162 and K648)

        The High Resolution Spectrograph was used to make seven spectral
        observations of the post-AGB star K649 which is located inside a
        planetary nebula in the globular cluster M-15. All seven
        observations were received and displayed. All of the following
        spectra was reported to look good. 

   1.12 Completed PC 4714 (PC/WF Cycle 2 Calibration: Internal Delta Flats)

        The Planetary Camera was used to make internal flat observations to
        be used for the restoration of Earth flat images, which were
        altered due to changes in quantum efficiency which occurred during
        decontamination operations. The observations were executed as
        scheduled, and no problems were reported.
