Daily Status Report as of 145/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 4792 (Hydrogen Lyman Alpha Day Glow Emission Line 
       Profiles from Outer Planets)

       The High Resolution spectrograph was used to make four spectral
       observations of the planet Jupiter looking for day-glow emission in
       Lyman Alpha. The observations were made in the central meridian at
       the equator, and at mid-latitude (About 30 degrees north). All four
       observations were received and displayed in the OSS. They were
       reported to look okay. 

   1.2 Completed WFC 4929 (WF/PC Cycle 2: Improved Dark Calibration)

       The Wide Field Camera was used to make two internal dark calibration
       images. Each observations was 1200 seconds long, and each was
       pre-flashed. Both of the dark observations were received and
       displayed. they both were reported to be okay. 

   1.3 Completed FGS 2941 (High Speed Astrometry - A Search for Planetary 
       Companions to Low Mass)

       The Fine Guidance Sensors were used to make astrometric observations
       of Barnard's star and a nearby field of reference stars. This is to
       look for a possible Jupiter sized planet in orbit around the target
       star. The astrometric observations were monitored in the OSS, except
       for a short period during ZOE. There were no problems seen in the
       telemetry. 

   1.4 Completed PC 3603 (Snapshots of Protoplanetary Nebulae)

       The Planetary Camera was used to attempt to take two snapshot of the
       protoplanetary system V821 Hurculis. There was no target visible in
       either of the two observations. 

   1.5 Completed FOC/96 5009 (ST Focus Investigation)

       The Faint Object Camera (f/96) was used to obtain images of several
       stars (i.e., M-11 an open cluster in Secutum) to determine how the
       focus changes with orbital phase. This is also called the "breathing
       Test". This observations will also be used with other FGS
       astrometric observations. (See Note 2.4, and 1.6) The observations
       was reported to have gone very well. 

   1.6 Completed FGS 5011 (Astrometry for ST Focus Investigation)

       This is the second half of "Breathing Test" (i.e., Proposal FOC/96
       5009). The two astrometric observations were reported to have gone
       well. (See Note 2.4 and 1.5). 

   1.7 Completed FOS/BL 4054 (Probing the Nuclear Regions of Seyfert Galaxy 
       NGC-5548)

       The Faint Object Spectrograph was used to make spectral observations
       of the nuclear region of Seyfert galaxy NGC-5548 looking for time
       dependent changes in its continuum, and emissions in Helium II and
       Carbon IV. The observations were executed as scheduled, and no
       problems were reported. 

   1.8 Completed WFC 4381 (HST Medium - Deep Survey - Cycle 3)

       The Wide field Camera was used to make medium - deep sky survey
       observations take in parallel with the prime science observations.
       The OSS monitored the observations and assessed the data quality. No
       problems were reported.

   2.4 Operations Note:

       FGS "Breathing" Test
       --------------------

       A test using all three FGSs is currently under way (Monday, May 24).
       This test will take repeated astrometry observations using a small
       set of stars to investigate scale changes ("breathing") in the
       spacecraft structure. The first two astrometric observations have
       been completed, and are currently being analyzed. The test will
       continue for one more day.
