                               DAILY REPORT #808

PERIOD COVERED:  0800 EST 01/22/93 - 0800 EST 01/25/93

Daily Status Report as of 025/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/UV2 1095 (Variability of High Luminosity Stars)

       The High Resolution Spectrograph was used to make ultraviolet
       observations of the vary massive high luminosity star HD15570. The
       observations were executed as scheduled, and no problems were
       reported. 

   1.2 Completed GHRS/2 3578 (Line Eclipse Mapping of Accretion Disk Wind)

       The High Resolution Spectrograph was used to make four spectral
       observations of the eclipse of the accretion disk of the cataclysmic
       variable star UX Ursa Majoris. All four observations were received
       and displayed. All of the spectral observations were reported to
       look normal. 

   1.3 Completed GHRS/2 4462 (SSA A2 Offset Verification)

       The High Resolution Spectrograph was used to make three positional
       observations of HD141556 to measure the position of the Small
       Science Aperture (SSA) with respect to the Large Science Aperture
       (LSA). All three to the target acquisitions and spectral
       observations were successful. 

   1.4 Completed PC 4347 (Flood Retention Test)

       The Planetary Camera was used to make three Earth flat calibration 
       observations using filter F439W. These observations will be compared
       with those made in the past using the same filter, to determine how
       much of the last ultraviolet flood still remains. The observations
       were monitored in the OSS, and no problems were reported. 

   1.5 Completed Two Sets of GHRS/2 2537 (Physical Conditions of
       Interstellar Gas) 

       The High Resolution Spectrograph was used to make high signal to
       noise ratio spectral observations of gas within 150 light years
       using star HD102647 (aka, Beta Leo, Denobola) to study the hot and
       cold regions of the interstellar medium. The spectral observations
       looked normal. The wave calibration images were contaminated by
       light from the target (which entered the HRS through the Small
       Science Aperture). 

   1.6 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.7 Completed WFC-PC 4109 (Rapid Internal Monitor)

       Both the Wide Field Camera and the Planetary Camera were used to
       make internal flat observations to check for different forms of
       contamination (i.e., daisies and measles). The OSS monitored to
       observations and assessed the data quality. No problems were
       reported. 

   1.8 Completed Two Sets of PC 3848 (Separate Light Curves of Pluto and 
       Charon)

       The Planetary Camera was used to make two observations of the planet
       Pluto, and its moon Charon (each individually). Each of the images
       were taken using a comparison star which was about 25 arcseconds
       from the targets. The observations were completed as scheduled, and
       no problems were reported. 

   1.9 Completed FOS/RD 4052 (Inner Regions of Quasars)

       The Faint Object Spectrograph was used to make four ultraviolet
       observations of the inner regions of quasar B20923+39. The
       observations were received and displayed. They were reported to look
       a little noisy, but were otherwise okay. 

   1.10 Completed WFC 3917 (HST Medium Deep Survey, Part 1)

       The Wide Field Camera was used to make two high latitude
       observations which were taken in parallel with the prime science
       observations. Both observations were received and displayed in the
       OSS. They were reported to look okay. 

   1.11 Completed WFC 4216 (Calibration of Supernova)

       The Wide Field Camera was used to take three images of object
       IC4182. The images were received and displayed, and reported to look
       normal. 

   1.12 Completed WFC 2227 (Determine Extragalactic Distance Scale: M-81)

       The Wide Field Camera was used to make observations to the galaxy
       NGC-3031 (aka, M-81) to search for variable Cepheid stars using both
       filter F555W and F785LP individually. The observations were executed
       as scheduled, and no problems were reported. 

   1.13 Completed GHRS/2 3444 (Gas in Individual Interstellar Clouds)

       The High Resolution Spectrograph was used to make observations of
       early type star HD36486 to study the interstellar clouds which lie
       along the line of sight to that star. The observations were
       monitored in the OSS, and no problems were reported.
