1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 5299 (Highly Ionized Gas in the Warped Outer 
       Galaxies: Cycle 4 Medium)

       The High Resolution Spectrograph (Side Two) was used to make
       observations of highly ionized gas in the Milky Way disk and halo as
       seen in the spectrum of the bright quasar H1821+643. The mechanism
       which produces this ionization is not understood. The observations
       were executed as scheduled, and the data remains on the science tape
       recorder. It will be analyzed later. No anomalies were noted. 

   1.2 Completed WF/PC-2 5561 (WF/PC-2 Cycle 4 Calibration: Internal 
       Monitor. 2: Flats)

       The WF/PC-2 was used to make a visual flat calibration image to
       monitor flat field stability and the stability of the
       analog-to-digital converters. The observation was monitored by the
       OSS, and the data quality was assessed. No anomalies were noted. 

   1.3 Completed WF/PC-2 5415 (The Distance to the M-96 Galaxy Group: Cycle 
       B4 Medium)

       The WF/PC-2 was used to make observations of Cepheid variable stars
       within the galaxy NGC-3368 whichY itself is located in the M-96
       galaxy cluster. This is to help determine the distance to this
       galactic group, and to improve the determination of the Hubble
       constant. The observations were executed as scheduled, and no
       anomalies were noted.

   2.3 Significant HSTARs: None

   2.4 Operations Notes: 

       No problems were experienced during the last twenty-four hours in
       any HST subsystem. 

       Yesterday, at 1942Z, the battery 5 CCC relay K51 trip point was
       changed to level 3 in order to maintain battery 5 charge consistent
       with the other batteries. The battery temperature high limits were
       also lowered to provide further monitoring. 

       HST Flight Software and DMS Engineers completed execution of the
       DF-224 Coprocessor Aliveness and Functional Test on day 095. The
       test performed checks on all pin connections between the DF-224 and
       the 80386 including address and data lines and interrupt lines. The
       test verified proper timing between the two systems and full
       functionality of the 80386 system by executing the onboard processor
       bootstrap self-test. 

       The test took less than the allotted time due to the fact that the
       hardware passed all tests flawlessly. These results provide high
       confidence that all the hardware is functioning as expected. 

       The system was configured with four additional shared memory units
       on the DF-224 Bus (memory accessible by the DF-224 and the 80386).
       The 80386 bootstrap software will be performing checksum tests on
       all the shared memory and report any upsets in the memory or CPU. 

       Completion of these activities positions the system for use of
       additional memory for stored commands currently being prepared for
       the on-orbit spacecraft transfer functional test.
