PERIOD COVERED:  0000Z (UTC) 07/29/96 - 0000Z (UTC) 07/30/96

Daily Status Report as of 212/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6584 (Interaction of Supernovae With =
Curcumstellar Material)

       The WF/PC-2 was used to make observations of Supernova SN1979C.  =
The objective is to study the interaction between the supernova and the =
remnant circumstellar material from the progenitor star, and how that =
interaction can sustain supernovae luminosity for long periods.  The =
observations were completed as planned, and no problems were reported.

   1.2 Completed FOS/RD 6167 (FOS Cycle 5: Dark Monitoring)

       The Faint Object Spectrograph (Both Red and Blue Sides) was used =
to make several dark calibration images.  All exposures were internals.  =
All spectra were done in the image mode.  The observations were completed =
as planned, and no problems were reported.

   1.3 Completed GHRS/1 6692 (The Abundance and Distribution of Deuterium =
on Saturn)

       The High Resolution Spectrograph (Side One) was used to make =
observations of the limb of the planet Saturn and its moon Rhea in order =
to study the abundances and distribution of Deuterium in Saturn's upper =
atmosphere.  The GHRS aperture was allowed to drift across Saturn's limb, =
mimicking an occultation.  A wavelength calibration image was also taken. =
 The observations were executed as scheduled, and no anomalies were =
noted.
