PERIOD COVERED:  0000Z (UTC) 12/12/96 - 0000Z (UTC) 12/13/96

Daily Status Report as of 348/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6348 (Blue Continuum Snapshots of 3CR Radio =
Galaxies)

       The WF/PC-2 was used to make some snapshot images of the blue =
continuum in radio galaxy 3C411.0.  Combined with existing data, these =
exposures will provide high spatial resolution information on the color =
distribution within galaxies, redding due to dust, spacial indices of the =
optical synchrotron jets, and colors of the active nuclei and tidal jets. =
 The observations were executed as scheduled, and no anomalies were =
noted.

   1.2 Completed FOS/BL/GHRS/1 6918 (FOS Cycle 6: Internal/External =
Offset)

       The Faint Object Spectrograph (Blue Side) and the High Resolution =
Spectrograph (Side One) were both used to make observations of standard =
star HD207757 in order to make internal and external calibration =
measurements.  Offsets between internal and external wavelength scales =
were measured for several different gratings.  The observations were =
executed as scheduled, and no anomalies were noted. 

   1.3 Completed FOS/RD/GHRS/1 6911 (FOS Cycle 6: Discriminator Test)

       The Faint Object Spectrograph (Red Side) and the High Resolution =
Spectrograph (Side One) were used to make internal flat and a dark =
calibration images as part of a Cycle 6 optimal discriminator setting =
test.  This must be done because the noise and gain are both known to be =
temperature sensitive.  Observations were also taken of standard star =
HD207757.  The observations were executed as scheduled, and no anomalies =
were noted. 

   1.4 Completed GHRS/1 6575 (Observations of Interstellar Clouds in the =
Galactic Halo)

       The High Resolution Spectrograph (Side One) was used to make =
ultraviolet spectrographic observations of the halo star HD119608 in =
order to study the foreground interstellar medium absorption lines.  =
These spectra will be used to determine the physical properties of the =
individual clouds, and will provide more information on the elemental =
abundances, the relation between the ionized and neutral gas,  and the =
distribution of the various species.  The observations were completed as =
planned, and no problems were reported.

   2.3 Operations Notes: 

       Aside from several temperature limit violations which normally =
occur at this time of the year, there were no reported operational =
problems.
