PERIOD COVERED:  0800 EST
Daily Status Report as of 056/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of HSP/UV1 4209 (HSP Detector Sensitivity Test)

       The High Speed Photometer was used to make four ultraviolet
       observations of standard star VID998 to measure the sensitivity of
       its detector tubes. The observations were executed in fine lock. The
       data was displayed for a representative of the principal
       investigator. No problems were reported. 

   1.2 Completed Three Sets of WFC 4713 (WF/PC Calibration: WFC Internal
       Delta Flats) 

       The Wide Field Camera was used to make one internal flat
       observation. This image will be used for the restoration of Earth
       Flats, which are altered due to the changes in quantum efficiency
       which occurred after WFPC decontamination operations. The image was
       received and displayed. The internal flat was reported to look
       normal. 

   1.3 Completed HSP/UV2 1095 (Variability of High Luminosity Stars)

       The High Speed Photometer was used to make three observations of one
       of the most luminous and massive stars known, HD93250. All three
       observations were made in fine lock. A recentering event occurred
       during the last observation. All of the images were displayed for
       the principal investigator. 

   1.4 Completed FGS 4064 (Crit. Test of Galactic Escape Velocities at  
       R(Sun))

       The FGSs were used in their astrometric mode to make positional
       measurements of star G1625 to determine its parallax and proper
       movement. The observations were made in fine lock. One recentering
       event was seen, and no other problems were reported. 

   1.5 Completed Two Sets of WFC 4105 (HST Medium Deep Survey: High Latitude)

       The Wide Field Camera was used to make a total of four medium-deep
       sky survey images taken in parallel with the prime science
       observations. All of the observations were taken in fine lock. A
       recentering event occurred during the first image. The other
       observations were reported to be normal. 

   1.6 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.7 Completed PC 3209 (PC Images of Eta Carnae Core)

       The Planetary Camera was used to make a series of 24 observations of
       the Star System Eta Carnae. The first series was received and where
       possible displayed. They were reported to look normal. The last ten
       observations still remain on the science tape recorder, and will be
       analyzed later. 

   1.8 Completed PC 3603 (Snapshots of Protoplanetary Nebulae)

       The Planetary Camera was used to make observations of the
       protoplanetary system CPD-53D573. The observations were executed as
       scheduled, and no problems have been reported. 

   1.9 Completed FOS/RD 4495 (FOS GIMP Test)

       The Faint Object Spectrograph was used to initiate a spectral test
       to measure geomagnetically induced movement in its detector tubes.
       (See Operations Note 2.4) The test is currently under way, and no
       problems have been reported.

   2.4 Operations Note:

       A Geomagnetic Induced Movement Problem (GIMP) Test is currently
       under way. The Red Side of the test has been completed
       (056/0500Z-0930Z). The test results were displayed in the OSS, and
       the image motion has been taken out. This section of the test
       appears to be a success. The Blue Side of the test is still ongoing
       (056/11Z-1600Z).
