1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5629 (WF/PC-2 Cycle 4 Photometric Calibration 
       Monitor 1C: 4-Chip STD in F170W)

       The WF/PC-2 was used to make photometric calibration observations of
       the ultraviolet standard star GRW+70D582. The observations were executed 
       as scheduled, and no anomalies were noted. 

   1.2 Completed FOS/BL 5610 (Symbiotic Systems in the Magellanic Clouds 
       Cycle 4 High)

       The Faint Object Spectrograph (Blue Side) was used to make
       ultraviolet observations of the symbiotic system S63 located in one of 
       the Magellanic clouds to learn more about the hot components in this 
       system, such as radiation temperature and the luminosity. The 
       observations were completed as planned, and no problems were reported.

   1.3 Completed GHRS/2 5414 (Dayglow Emission Line Profile from the Outer 
       Planets: cycle 4 Medium)

       The High Resolution Spectrograph (Side Two) was used to make
       observations of the Lyman-Alpha profiles of the moon Triton on Neptune. 
       A wavelength calibration observation was also taken. The observations 
       were completed as planned, and no problems were reported. 

   1.4 Completed WF/PC-2 5571 (WF/PC-2 Cycle 4 Calibration: Earthflats, 
       Smaller Set)

       The WF/PC-2 was used to make several ultraviolet and narrow-band
       filter Earth flat calibration observations to correct for the telescope's
       illumination pattern. The observations were completed as planned, and no
       problems were reported. 

   1.5 Completed WF/PC-2 5493 (Synoptic Monitoring of Seasonal Phenomena 
       on Mars: Cycle 4 Medium)

       The WF/PC-2 was used to make observations of the planet Mars at
       selected seasons, looking for periodic changes. The observations were
       executed as scheduled, and no anomalies were noted. 
 
   1.6 Completed FGS 5554 (HIPPARCOS Plate Scale: Cycle 4 Calibration) 

       FGS#3 was used to make astrometric observations of stars HIC22604,
       H39-385-RE, H39-366-RE, H39-255-RE, HIC22507-R which were observed by the
       HIPPARCOS satellite. The astrometric observations were monitored while
       telemetry was available. 

   1.7 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 High, High 
       Galactic Latitude)

       The WF/PC-2 was used in parallel with the prime science observations
       to make high galactic latitude observations as part of a medium-deep sky
       survey. The observations were completed as planned, and no problems were
       reported. 

   1.8 Completed FOS/BL 5182 (UV Spectroscopy of Low Redshift Active 
       Quasars: Cycle 4)

       The Faint Object Spectrograph (Blue Side) made ultraviolet
       observations of the low redshift active quasar AKN120 to obtain the
       profiles of the emission lines, and the ratios of their fluxes. 
       HSTAR 4915 was written for this proposal since the binary search for
       the target star failed.

   1.9 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4) 

       The WF/PC-2 was used to make observations taken in parallel with the
       prime science observations. This is part of a survey to take pictures of 
       a large number of fields within 30 degrees of the galactic plane. The
       observations were completed as planned, and no problems were reported. 

   1.10 Completed FOS/RD 5588 (FOS Prism Snapshot Survey)

       The Faint Object Spectrograph (Red Side) was used to make a Prism
       observation of quasi-stellar object AKN120 to study its optical to
       ultraviolet continuum shape. The observations were executed as scheduled,
       and no anomalies were noted. 

   1.11 Completed WF/PC-2  5476 (Continuum Snapshots of 3CR Radio Galaxies) 

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C135.0
       as part of a continuum survey and to study the galaxy's morphology. The
       observations were executed as scheduled, and no anomalies were noted. 

   1.12 Completed WF/PC-2 5678 (Resolution of the Upper IMF in the 
        Magellanic Clouds: Cycle 4)

       The WF/PC-2 was used to make observations of the bright O class
       star HD32228 which is located in the Magellanic Cloud to determine if 
       this star actually contains combinations of unresolved stars. The 
       observations were executed as planned, and no problems were reported.

   2.3 Significant HSTARs: None

   2.4 Operations Notes: 

       There were no anomalies reported in any subsystem aboard the HST.

       A flight software patch was uplinked yesterday modifying the SA Post
       Maneuver Timeout sequence.  Subsequent SA slew activity indicated
       that the new sequence performed nominally.

3.0 ANOMALY STATUS:

   3.1 Significant New Anomalies: None

   3.2 Significant Unresolved Anomalies: None

4.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
