1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FGS 5059 (Seven Points of Light _ Cycle 2 Calibration - 
       Fixed)
 
       The Fine Guidance Sensors were used to make observations of standard
       star UPGREEN-69. The objective was to calibrate the single star
       interferometeric fringe pattern at seven different points in the
       central region of the astrometric FGS. The astrometric observations
       were monitored and no problems were seen in the telemetry. 

   1.2 Completed Three sets of GHRS/2 4344 (The Mass of White Dwarf V471
       Tuari - 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. Eight
       observations were received and displayed. The observations were
       reported to look normal. 

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

       The FGSs were used to make astrometric observations of the possible
       binary star VA537 which is located in the Hyades open cluster. The
       OSS monitored the observation, and no anomalies were reported. 

   1.4 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
