PERIOD COVERED:  0800 EST
Daily Status Report as of 215/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/BL 4468 (Ultraviolet Spectropolarimetry of AG Car in
       its Current Outburst Cycle ) 

       The Faint Object Spectrograph was used to make observations of the
       variable star AG Carine (aka, HD94910) and the standard polarization
       standard star BD+64D106. AG Carine is known to have outburst about
       once every 15 years during which the mass loss rate increases
       significantly. The peakup stopped cold after the ninth dwell point,
       and five status buffer error messages were output. At the same time
       the WFPC was undergoing a flash decontamination procedure, and
       output an error of its own. Engineers were called in both at the OSS
       and MOR. As of this writing, the problem seems to have been that a
       minor frame pulse didn't get to the instruments. Further analysis is
       continuing. The subsequent peakups were executed without problems.
       But the counts indicated the target was not well centered. The
       following polarization observation was received and displayed. The
       counts were fairly high. 

       A recentering event occurred during the next science observation,
       but the jitter did not seem unusually high. The next two science
       observations looked good, but it appeared as if the target was not
       well centered in the aperture. 

       During a later observation, a loss of lock prevented the shutter
       from opening. The current flight software caused the shutter to
       remain closed for the entire duration. As a result, no observations
       were obtained for this proposal. An HSTAR was written. 

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

       The Faint Object Spectrograph (Red Side) was used to make one
       spectrographic observation of quasar 0355-4820 to look for
       absorption line systems at low red shift, emission lines, and to
       study the QSO's continuum. The observation was executed as
       scheduled, and no problems were reported. 

   1.3 Completed FOS/BL 4976 (UV Rotation Light Curves for Pluto, and 
       Charon's UV Spectrum - Split)

       The Faint object Spectrograph was used to make a TALED exposure
       subsequent to other spectral observations of the planet Pluto and
       its moon Charon. After a corrective SIP maneuver was uplinked to the
       spacecraft, spectral observations were made of the planet Pluto. The
       observations were executed in fine lock. No problems were reported. 

   1.4 Completed WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal 
       Monitor)

       Rapid Internal Monitoring observations were made with both the Wide
       Field Camera and the Planetary Camera using filter F555W to look for
       new forms of contamination (i.e. daises and measles), and the
       possible return of quantum efficiency hysteresis. The observations
       were monitored in the OSS, and the data quality was assessed. No
       problems were reported.
