1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed  FOC/96 4909 (Polarization Imaging of the Jet in Markarian
       463: Cycle 3 Medium) 

       The Faint Object Camera was used to make one image of the Markarian
       galaxy 463. This object is a pair of galaxies which is merging, 
       with a separation of four arcseconds between their nuclei. The
       observations was executed without problems, and was received via a
       science tape recorder playback. The target appeared well placed in
       the aperture, and well exposed. 

   1.2 Completed HSP/UV2 4946 (Variability of High Luminosity Stars - Cycle 
       2 High)

       The High Speed Photometer was used to make two 80 minute observation
       of the massive high luminosity star HD216411 looking for short
       period fluctuations in its luminosity. The first data take was
       effected by a centering event which occurred during the observation.
       The second observation was reported to look normal. 

   1.3 Completed Three Sets of WFC 4277 (Calibration of Nearby Galaxy Type 
       IA Supernovae as Standard Candle)

       The Wide Field Camera was used to make a total of eight observations
       of Cepheid variable stars located inside fo galaxy NGC-5253. This is
       to help determine the accurate distance scale to this galaxy. The
       distance will be used to find the true luminosity of the type - Ia
       supernova which has been observed in this galaxy. All eight
       observations were reported to be satisfactory. Recentering events
       were reported to have occurred during three of the observations. 

   1.4 Uplinked Updated Ephemeris Tables, Per MOSES 2871 

   1.5 Completed FOS/RD 4697 (FOS Polarization Calibration)

       The Faint Object spectrograph was used on both sides (i.e., Red and
       Blues Sides) to obtain a series of measurements of the internal
       Pt-Ne lamps to locate the two oppositely polarized spectra that
       occur with the polarimeter. The Red Side only was used to make
       observations of standard star BD+28D4211. The observations were
       reported to be successful. 

   1.6 Completed PC 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 reported
       to be normal exposures. 

   1.7 Completed FOS/BL 3862 (The Excitation fo the Atmospheres of
       Planetary Satellites) 

       The Faint Object Spectrograph was used to make spectral observations
       of Jupiter's moon Io as it egresses from the planet's shadow. The
       target was reported to be well centered, and the principal
       investigator decided that a pointing corrective maneuver was not
       needed. The moon was coming out of the eclipse during the first
       observation. The data looked normal, with a good signal to noise
       ratio. The observation went as intended. 

   1.8 Completed PC 3594 (Imaging Polarization of the M-87 Nucleus and Jet)

       The Faint Object Camera (f/96) was used to make images in polarized
       light of the jet and the inner nuclear regions of the galaxy M-87
       (aka, NGC-4486). The goal was to map the distribution of
       polarization in the jet and to measure the polarization of the
       nucleus at ultraviolet and optical wavelenghts. The observations
       were executed as scheduled, and no problems were reported. 

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

       The Faint Object Camera was used to complete two sets of snapshot
       ultraviolet observations fo the nearby galaxy UGC-7322. The
       exposures lasted for ten minutes and used filter F220W. Both sets of
       observations were reported to be fine. 

   1.10 Completed GHRS/2 4124 (GHRS Sensitivity Monitor - Cycle 2)

       The High Resolution Spectrograph was used to make a series of
       observations using standard star BD28D4211 to look for changes in
       the instrument's sensitivity. The onboard target acquisition was
       successful. All following fifteen observations were reported to look
       fine. 

   1.11 Completed Two Sets of FOS/RD 4097 (FOS Location of Spectral Y -
       Base Maps) 

       The Faint Object Spectrograph was used to make two sets of eight
       (each) Y-Base calibration images. All sixteen observations were
       reported to be normal. 

   1.12 Completed FOS/RD 4941 (Geometry and Generalizability of the 
       Reflected Light Model from Seyfert)

       The Faint Object Spectrograph was used to make observations of the
       Seyfert Galaxy MARK 477. The observations were monitored in the OSS,
       and the data quality was assessed. No problems were reported. 
 
   1.13 Completed Two Sets of  WFC 4381 (HST Medium - Deep Survey - Cycle
       3) 

       The Wide Field Camera was used to make two set of medium-deep high
       latitude sky survey observations taken in parallel with the prime
       science observations. The observations were executed as scheduled,
       and no problems were reported. 

   1.14 Completed WFC/PC 4207 (WF/PC Cycle 2 Calibration: Photometric 
       Calibration Monitor)
 
       Both the Wide Field Camera and the Planetary Camera were used to
       make ultraviolet calibration images of standard star BD+28D4211. The
       observations were received and displayed in the OSS. There were no
       apparent problems reported with the exposures. 

   1.15 Completed FOS 3441 (Post Asymptotic Giant Branch Evolution in the 
       Magellanic Clouds) 

       The Faint Object Spectrograph was used to make three spectral
       observations of the planetary nebula SMC-SM40 which is located in
       the Small Magellanic Cloud. A recentering event occurred during the
       first observation. The last two observations were reported to be
       okay. 

   1.16 Completed FOC/96 4821 (Magellanic Cloud Planetary Nebulae: Cycle 3 
       Medium)

       The Faint Object Camera was used to make observation of the
       planetary nebulae LMC-LM1-27 which is located in the Large
       Magellanic Cloud. The observation was taken during LOS, and still
       remains on the Science Tape Recorder. The observation will be
       analyzed later. 

   1.17 Completed WFC 4849 (GTO High Latitude Parallel Program, Cycle 3
       High) 

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