1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of FOS/BL 3545 (Evolution of Ultraviolet Spectra
       in Early Type Galaxies) 

       The Faint Object Spectrograph was used to make four spectral
       observations of early type galaxy 55W037. It observations was made
       in parallel with the prime science observation. All four
       observations were executed in course track. They were received and
       displayed in the OSS. They were all reported to look good. 

   1.2 Completed WFC/PC 4109 (WF/PC Calibration: Rapid Internal Monitor)

       Both the wide Field Camera and the Planetary Camera were used to
       make internal flat observations to look for new forms of
       contamination (i.e., measles and daisies), and the return of quantum
       efficiency hysteresis. Both images were received and examined in the
       OSS. They were reported to look normal. 

   1.3 Completed Two Sets of PC 4714 (WF/PC Calibration: PC Internal Delta 
       Flats)

       The Planetary Camera was used to make a total of three internal
       delta flat images. These images will be used for the restoration of
       Earth flats, which were are altered due to changes in quantum
       efficiency which occur after WFPC decontamination operations. All
       three images were displayed, and reported to look okay. 

   1.4 Completed WFC 4713 (WF/PC Calibration: Internal Delta Flats)

       The Wide Field Camera was used to take one internal flat
       observation. The image was displayed in the OSS, and was reported to
       look okay. 

   1.5 Completed PC 3769 (Spectra of Inner Coma of Comet Chrion)

       The Planetary Camera was used to make 13 observations of the
       comet/object Chiron to study the inner coma region, and dust near
       the edge of its exopause. The first nine observations were received
       and displayed. They were reported to look okay. The next four
       observations were executed in course track. These were point spread
       function observations and the engineering telemetry rate was only 4K
       for these observations. The observations were reported to look okay,
       however, they were filed as being bad because the engineering
       telemetry was in the low data rate. 

   1.6 Completed GHRS/2 3862 (Excitation of Atmospheres of Planetary 
       Satellites)

       The High Resolution Spectrograph was used to make eight spectral
       observations of Jupiter's moon Io while it entered the planet's
       shadow. All eight observations were received and where possible
       displayed. The onboard target acquisition was successful. The
       spectrum was reported to look normal. 

   1.7 Completed Two Sets of FOS/RD 4784 (Transition Comets: UV Search for OH)

       The Faint Object Spectrograph was used to make two observations of
       the asteroid HIDALGO looking for OH emission lines at 3085 A0. All
       three observations were received and displayed. The first
       observation was the onboard target acquisition. It was successful.
       The second was the ultraviolet spectral observation. It was reported
       to look normal. 

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

       The Planetary Camera was used to make point spread function
       observations and focus change observations using standard star
       SAO62896. These changes may have been caused by desorption or other
       changes in the WFPC system. The observations were executed as
       scheduled, and no problems were reported. 

   1.9 Initiated HSP/UV1 4209 (HSP Detector Sensitivity Test)

       Observations were initiated using the High Speed Photometer to
       measure the sensitivity of the four HSP Image Detector Tubes. The
       calibration source is standard star VID998. The observations are
       currently under way, and no problems have been reported.

   2.4 Operations Note: 

       A special FGS #2 analysis and review meeting to study the star servo 
       A anomaly was held yesterday at GSFC (Tuesday, Feb. 23,1993). This
       meeting lasted all day and included experts from both government and
       industry on bearings, motors, and servos. The meeting will continue
       this afternoon (Wednesday, Feb. 24) at 1 p.m.
