PERIOD COVERED:  0800 EST
Daily Status Report as of 239/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FGS 4893 (Orbital Motions of Close Binary Stars - Cycle 3 
       High)

       Fine Guidance Sensor #3 was used to make astrometric observations of
       the binary star system HD193194 to obtain its orbital elements.
       These observations are important since most of the estimates of
       stellar mass are made by observing elements of these systems. The
       astrometry was monitored and no problems were seen in the telemetry. 

   1.2 Completed Two Sets of HSP/POL/UV2 5082 (X-Ray binaries Part 2 - Cycle 
       3 High)

       The High Speed Photometer was used to make 15 photometric and
       polarimetric observations of X-Ray binary star HD153919 (aka,
       3U1700_37) to obtain more information about the structure and
       condition in the gas streams connecting the primary star to its
       neutron companion. All 15 observations were received and displayed
       in real-time. The observations were reported to be nominal. 

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

       The Wide Field Camera was used to make two 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 observations were received and
       displayed. One observation was reported to be saturated, and the
       others were okay. 

   1.4 Completed FGS 5062 (Scale Cycle 2 Calibration: Fixed)

       Fine Guidance Sensor #3 was used to calibrate the scale in the
       central region using standard star HD16620. The observations were
       executed as scheduled. The observations could not be monitored
       because line #720 was down. The fail-over to line #732 was not
       accomplished until after the observation had completed. 

   1.5 Completed FGS 5118 (Monitor the Long Term Stability of the FGSs 
       Revised)

       FGS #3 was used to measure the position of standard stars OF-41,
       OF-83, and OF-40 to monitor its internal positional stability. The
       astrometry was monitored and no problems were seen in the telemetry,
       except for one recentering event which occurred near the start of
       the first observation. 

   1.6 Completed Two Set of FGS 4892 (Duplicity Among Hyades Stars - Cycle 3 
       High)

       The FGSs were used to make astrometric observations of the possible
       binary star VA637 which is located in the Hyades open cluster. The
       OSS monitored the observation, and engineering link was reported to
       have been lost for part of the observation. 

   1.7 Completed Two Sets of PC 5014 (WF/PC Cycle 3 Calibration: PC Flats 
       Narrow. 2)

       The Planetary Camera was used to make two standard Earth
       calibrations images for flat fielding of PC observations. Medium and
       narrow filters were used, with and without neutral density filters.
       Both observations were executed as scheduled, and the observations
       were reported to look normal. 

   1.8 Completed GHRS/2 4835 (Composition of Gas in Individual Interstellar 
       Clouds: Cycle 3 High)

       The High Resoltion Spectrograph was used to make observations of
       class B 0.5 Type II halo star HD149881 to look for absorption line
       from C, N, O, Si, Mg, and S which is contained in gas in the
       interstellar clouds which lie alone the line of sight of the target
       star. The observations were monitored in the OSS, and the data
       quality was assessed. No problems were reported.
