PERIOD COVERED:  0800 EST
Daily Status Report as of 148/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

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

       The Wide Field Camera was used to make one high latitude medium -
       deep sky survey image taken in parallel with the prime science
       observations. The observation was monitored in the OSS, and was
       reported to look fine. 

   1.2 Completed Two Sets of FOC/96 3801 (Search to QSOs Suitable for
       Subsequent Observations of He II) 

       The Faint Object Camera was used to make three images of
       quasi-stellar object 1304+295 to find out if the object has
       sufficient ultraviolet flux levels for subsequent observations using
       the GHRS and FOS. All three observations were received in the OSS.
       No problems were noted. 

   1.3 Completed Two Sets of FOS/BL 3683 (Accretion Disk Mapping in 
       Eclipsing Cataclysmic variables)

       The Faint Object Spectrograph (Rapid Mode) was used to make
       spectral observations of the cataclysmic variable star IP Pegasi
       during its eclipse with its accretion disk. The initial peakup
       failed due to  a loss of lock that occurred just shortly before the
       dwell scan began. (See Note 2.1 and 2.4) FGS control was regained in
       time for the second peakup to execute, but the OSS could not say if
       the target was well placed in the aperture. The first FOS rapid mode
       observation was scheduled too late to catch the eclipse. Three
       subsequent spectral observations were reported to look okay. 

   1.4 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.5 Completed GHRS/2 4601 (Jupiter's Hydrogen Lyman Alpha Auroral/Airglow 
       Line Profile: Cycle 3 Medium)

       The High Resolution spectrograph was used to make spectral
       observations of the Hydrogen I 1216 A0 line in Jupiter's atmosphere
       at latitudes of +40, +50, +55, +60, and +70 degrees on the central
       meridian. This is looking of emissions from the auroral torus. The
       observations were executed as scheduled, and no problems were
       reported.

       ----------------

       The Breathing Test was executed on the spacecraft on May 25-26.
       Preliminary indicators are that the test proceeded as planned. There
       were sessions of two data takes each. Each session included guide
       star acquisitions using fine lock, followed by parallel data takes
       involving FGS #2 as the astrometry FGS, and images from the FOC and
       WF/PC. Data analysis is now under way.
