PERIOD COVERED:  0700 EST
Daily Status Report as of 145/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed S/C 4974 (DF-224 FS Installation 9.0 and Higher)

       The installation of Flight Software 9.3 was executed as scheduled, 
and
       no anomalies were noted.

   1.2 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal
       Monitor. 1)

       The WF/PC-2 was used to make several internal bias, K-Spot, and flat
       calibration observations to monitor the CCD camera electronics, the
       optical alignment, and to check for contamination. A total of ten
       images was taken. There was one case of a bias jump, but no
       intensity gradients were seen.

   1.3 Completed FOS/BL 5418 (The Origin of the Ultraviolet Spectral
       Components)

       The Faint Object Spectrograph (Blue side) made observations of
       STAR-075117+144424 to obtain a rapid mode time resolved spectra. A
       total of eight observations were taken. Five observations were
       received and displayed, and they were reported to be okay. Three
       more observations remain on the Science Tape Recorder, and will be
       analyzed later.

   1.4 Completed WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal
       Monitor 3: Darks)

       The WF/PC-2 was used to obtain several 30-minute long, dark
       exposures to provide ongoing calibration of the CCD dark current and
       to monitor and characterize the evolution of hot pixels. The
       observations were executed as scheduled. Two observations were
       received and displayed. They were reported to be nominal. More data
       remains on Science Tape Recorder #1, and will be analyzed later.

   1.5 Completed WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4 Medium, High
       Galactic Latitude)

       The WF/PC-2 made a series of observations of high latitude objects
       as part of a medium deep sky survey. The observations were taken in
       parallel with other prime science observations. The observations
       were executed as scheduled. One observations was received and
       displayed. It was reported to look fine. More data still remains on
       Science Tape Recorder #1, and will be analyzed later. No anomalies
       were noted.

   1.6 Completed WF/PC-2 5561 (WF/PC-2 Cycle 4 Calibration: Internal
       Monitor 2: Flats)

       The WF/PC-2 was used to make a visual flat calibration image to
       monitor flat field stability and the stability of the
       analog-to-digital converters. The observations were executed as
       scheduled. The data still remains on Science tape Recorder #1, and
       will be analyzed later.

   1.7 Completed FOS/BL 5539 (Cycle 4 FOS Photometric Monitor)

       The Faint Object Spectrograph (Blue Side) used standard star
       BD+28D4211 to calibrate the absolute sensitivity of its detectors.
       The observations were executed as scheduled, and no anomalies were
       noted.
