                               DAILY REPORT #796

PERIOD COVERED:  0800 EST 01/04/93 - 0800 EST 01/05/93

Daily Status Report as of 005/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed S/C 4783 (DF-224 Version 8.3 Flight Software Installation)

       FSW 8.3 was successfully installed and is currently under going
       regression testing. FSW 8.3 contains the fine lock recentering
       algorithm which was designed to reduce fine lock loss of lock
       problems. No problems have occurred and the recentering algorithm is
       working as expected. 

   1.2 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.3 Completed HSP/UV2/POL 3234 (X-Ray Binaries)

       The High Speed Photometer was used to obtain eleven photometric and
       polarmetric light curve observations of the x-ray binary star
       HD77581. All eleven observations were examined in the OSS. The
       onboard target acquisitions were successful. There was a loss of
       lock which affected the last two observations. Otherwise, the
       observations looked good, and had a strong signal. 

   1.4 Completed Two Sets of WFC 3172 (Internal Monitor Proposal)

       The Wide Field Camera was used to take a series of internal dark,
       and bias observations. There were no external targets. The
       observations were executed as scheduled, and no problems were
       reported. 

   1.5 Completed WFC 2227 (Determine. of the Extragalactic Distance Scale)

       The Wide Field Camera was used to take a series of images of galaxy
       NGC-3031 (aka, M-81, a large spiral galaxy in Ursa Major) looking
       for Cepheid variable stars. This is to help improve our knowledge of
       the extragalactic distance scale. The observations were executed as
       scheduled, and no problems were reported. 

   1.6 Completed PC 4093 (A Snapshot of the Nuclear Regions)

       The Planetary Camera was used to take high resolution images of the
       inner regions of Markarian galaxy MARK74. The OSS monitored the
       observations, and assessed the data quality. No problems were
       reported.
