1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 4344 (The Mass of White Dwarf in V471 Tauri - Cycle
       3 High) 

       The High Resolution Spectrograph was used to make observations of
       V471 Tau (Visual Magnitude 10.7), which is an eclipsing binary star
       consisting of a white dwarf and a K2 class main sequence star. it 
       is hoped that the strong Lyman- Alpha absorption of the white dwarf
       can be used to determine its velocity curve, and that that can be
       used to calculate its mass. A total of eight observations were
       received and displayed. The onboard target acquisition was
       successful. The observations were reported to look normal. 

   1.2 Completed Two Sets of WFC 5076 (WF/PC Cycle 3 Calibration: WFC Flats 
       Wide. 2)

       Routine Earth flat calibration exposures were taken with the Wide
       Field Camera. The observations were monitored in the OSS, and the
       data quality was assessed. Two observations were received and
       displayed. Both were reported to be saturated. 

   1.3 Completed FOS/RD 4396 (QSO Absorption Systems Snapshot Survey - Part
       1 of 3: Cycle 3 High) 

       The Faint Object Spectrograph (Red Side) was used to make one
       spectrographic observation of quasar 0334-3617 to look for
       absorption line systems at low red shift, emission lines, and to
       study the QSOs continuum. The observations was received in real
       time. Two observations were displayed, and they were reported to
       look normal. 

   1.4 Completed Two Sets PC 5071 (WF/PC Cycle 3 Calibration: PC Flats 
       Narrow. 1)

       The Planetary Camera was used to make Earth calibration flat images
       which will be used to remove the pixel to pixel variations in gain
       of the chips. The flats from this proposal will be used for flat
       field corrections for subsequent science data. The observations were
       executed as scheduled. Four images were received and displayed. One
       was normal, two were partially saturated, and one was totally
       saturated. 

   1.5 Completed WFC 4322 (Resolution of the Upper IF in the Magellanic 
       Clouds: Cycle 3 High)

       The Wide Field Camera was used to make UV images of the star
       LUCKE-HODG (An O class star) which is located in the Large
       Magellanic Cloud to determine if there is any multiplicity in the
       system. Six observations were received and displayed. No anomalies
       were noted. 

   1.6 Completed PC 4940 (Post Asymptotic Giant Branch Evolution in the 
       Magellanic clouds)

       The Planetary Camera was used to make two images of the planetary
       nebula LMC-PSF-ST which is located in the Large Magellanic Cloud.
       These observations will provide information on the morphology, size,
       and dynamical age of the object. Both observations were displayed,
       and they were reported to look okay. 

   1.7 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.8 Completed HSP/POL 4887 (X-Ray Binaries - Augmentation - Cycle 3
       High) 

       The High Speed Photometer was used to make photometric and
       polarimetric observations of X-Ray binary star 4U1907-09 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. Five sets of observations
       were received and displayed. The target was well centered. The
       science observations were reported to have low and sparse counts. 

   1.9 Completed WFC/PC 5026 (WF/PC Cycle 3 Calibration: Rapid Internal 
       Monitor)

       The Wide Field Camera and the Planetary Camera were used to make
       internal flat calibration images. These images will be used to look
       for measles and daisies (i.e., different forms of contamination)
       and to monitor scattered light. Two observations were executed as
       scheduled, and no problems were reported. 

   1.10 Completed PC 3230 (PC PSF and Focus Monitoring 2)

       The Planetary Camera was used to make one set of images using 
       standard star SAO38744 which will be used to monitor the point
       spread function and focus changes which have occurred due to changes
       in desorption and other changes in the WFPC system. The observations
       were executed with no apparent problems. 

   1.11 Completed Two Sets of PC 5023 (Cal/WFPC Cycle 2 Polarization 
        Calibration)

       The Wide Field Camera was used to make polarization calibration
       observations by using images of a non-polarized standard star. This
       will allow for the absolute transmittance of the polarized optical
       path to be established. The observations were executed as scheduled,
       and no problems were reported. 

   1.12 Completed FGS 4892 (Duplicity Among Hyades Stars - Cycle 3 High)

       The FGSs were used to make astrometric observations of the possible
       binary star VA119 which is located in the Hyades open cluster. The
       OSS monitored the observation, and no anomalies were reported. 

   1.13 Completed WFC 4848 (GTO Low Latitude Parallel Program - Cycle 3 
        High)

       The Wide Field Camera was used to make two high latitude medium-deep
       sky survey observations taken in parallel with the prime science
       observations. Both observations were received and displayed. They
       were reported to look okay. 

   1.14 Completed WFC 5013 (WF/PC Cycle 3 Calibration: WFC Flats Narrow. 2) 

       The Wide Field Camera was used to make 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. The OSS monitored the observations and assessed the data
       quality. No anomalies were reported.
