                               DAILY REPORT #820

PERIOD COVERED:  0800 EST 02/09/93 - 0800 EST 02/10/93

Daily Status Report as of 041/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 2537 (Physical Conditions of Interstellar Gas)

       The High Resolution Spectrograph was used to make a series of 23
       observations in the direction of star HD80009 to obtain high signal
       to noise ratio spectra to study the interface between the warm and
       cold regions in the interstellar medium. All of the wave length
       calibrations and spectral observations were reported to look okay. 

   1.2 Completed PC 4347 (Flood Retention Test)

       The Planetary Camera was used to take three Earth flat images which
       will be used to determine how much of the last ultraviolet flood
       operation still remain. All three observations were received and
       displayed. The first image was underexposed, the second was okay,
       and the last was saturated. 

   1.3 Completed GHRS/2 3463 (Highly Ionized Nitrogen in Galactic Halo)

       The High Resolution Spectrograph was used to obtain a total of 11
       observations of Class O-7 halo type star HD156359 to obtain
       absorption line spectra of Nitrogen V. The confirmation images in
       the large and small science apertures looked good, with the target
       well centered in the large science aperture and only slightly off
       center in the small aperture. The wave length calibration and target
       spectra observations looked good.. 

   1.4 Completed GHRS/2 1179 (Hybrid Star winds and Transition Regions)

       The High Resolution Spectrograph was used to make six spectral
       observations of the star Alpha Traui (aka, First magnitude star
       Aldeberaun, HD150789) to help learn more about the temperatures,
       densities, out flow, velocities, and mass loss rates for hybrid
       stars. The observations were received in the OSS, and will be
       analyzed later. 

   1.5 Completed WFC-PC 4109 (Rapid Internal Monitor)

       Both the Wide Field Camera and the Planetary Camera were used to
       make internal flat observations to be used to check for new forms of
       contamination (i.e., measles and daisies). The observations were
       monitored in the OSS, and no problems were reported. 

   1.6 Completed PC 2944 (Internal Velocity Distribution in Globular 
       Clusters)

       The Planetary Camera was used to make observations of the globular
       cluster NGC-104 (aka, 47 Tucanae) to study its internal velocity
       dispersion. The observations were executed as scheduled, and no
       problems were reported.
