PERIOD COVERED:  0800 EST
Daily Status Report as of 196/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
 
   1.1 Completed FGS 5055 (A Critical Test of the Galactic Escape Velocity 
       at R(Sun): Cycle 1 Obsv.)

       This observation was not executed due to the current Safemode 
       event. (See Note 2.4) 

   1.2 Completed PC 5014 (WF/PC Cycle 2 Calibration: PC Flats Narrow. 2)

       This observation was not executed due to the current Safemode 
       event. (See Note 2.4) 

   1.3 Completed FOC/96 4804 (UV Imaging of Nearby Galaxies with the FOC/96)

       This observation was not executed due to the current Safemode 
       event. (See Note 2.4) 

   1.4 Completed Two Sets of FOS/RD 4953 (QSO Absorption Systems Snapshot 
       Survey - Part 3 of 3: Cycle 3 High)

       Both sets of observations were canceled due to the current Safemode
       event. 

   1.5 Completed WFC 5013 (WF/PC Cycle 3 Calibration: WFC Narrow. 2)

       This observation was not executed due to the current Safemode 
       event. (See Note 2.4) 

   1.6 Safemode Recovery 

       The return to SMS processing and science observations were
       successfully completed as scheduled at 195/2200Z. 

   1.7 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.8 Completed FOS/BL 4600 (FUV Spectroscopy fo Io's SO2 Atmosphere and 
       Surface - Cycle 3 High)

       The Faint Object Spectrograph (Blue Side) was used to make spectral
       observations of the bright and dark regions on the surface of
       Jupiter's moon Io. A scan across Io was also made. The objective of
       this proposal was to further characterize the behavior fo SO2 in
       Io's atmosphere. The first observation was received and the spectra
       was displayed with the wavelength scale in real time. A corrective
       maneuver was successfully uplinked. Post slew analysis indicated
       that there was a sign ambiguity in the reported wavelength shift, so
       the target was probably not entirely in the aperture. The pointing
       correction was only partially successful. In addition the target was
       not well-centered along the FOS/X-axis. The scan was supposed to
       cross the disk, parallel to the FOS/BL Y-axis. The tracking slew did
       nearly parallel the V1 axis, as it should, but the overlight sums
       were the greatest in the first readouts, instead of starting at
       small numbers, increasing, and then decreasing. Subsequent
       observations showed no apparent problems. 

   1.9 Completed FOS/BL 4952 (QSO Absorption System Snapshot Survey - Part
       2 of 2: Cycle 3 High) 

       The Faint Object Spectrograph was used to make an observation of
       quasar 1257+2840 to look for absorption lines at low redshift, and
       also emission lines in the QSO's continuum. The observations was
       executed as scheduled, and no problems were reported. 

   1.10 Completed GHRS/2 4271 (Testing the Star-Disk Connection: C IV and
       MG II Maps of Accretion Disks) 

       The High Resolution Spectrograph was used to make spectral
       observations of the dwarf nova system T-Leonis, which usually has a
       visual magnitude of 15.5 but may brighten to a magnitude of 10.0 for
       outburst. The OSS monitored the observations and assessed the data
       quality. A status buffer error message was received that the GHRS
       carrousel failed to stabilize during observation number six, which
       occurred during LOS. There was no impact to the science
       observations. 

   1.11 Completed PC 3603 (Snapshot of Protoplanetary Nebulae)

       The Planetary Camera was used to make a snapshot image of the
       protoplanetary system HD89353 to study its current morphology. The
       observation was complete as scheduled, and no problems were
       reported.
