PERIOD COVERED:  0000Z (UTC) 01/02/96 - 0000Z (UTC) 01/03/96

Daily Status Report as of 003/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Five Sets of GHRS/1 6171 (CRIMP1: Cycle 5 =
Condensed-Regimen Integrated Monitoring Program)

       The High Resolution Spectrograph (Side One) was used  to obtain =
darks, internal flats (in photoscan mode), wavelength calibrations and =
observations of standard star BD+28D4211.  This includes detector =
calibration, sensitivity monitoring, and wavelength monitoring.  The =
observations were executed as scheduled, and no anomalies were noted. 

   1.2 Completed Three Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  The =
observations were completed as scheduled, and no problems were reported.

   1.3 Completed WF/PC-2 6367 (High Resolution Imaging of Nearby Nuclear =
Starbursts)

       The WF/PC-2 was used to make high resolution images of the star =
bursting nuclei in galaxy NGC-253.  Selected narrow and wide band passes =
were used.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.4 Completed Four Sets of GHRS/2 6172 (CRIMP2: Cycle 5 =
Condensed-Regimen Integrated Monitoring Program)

       The High Resolution Spectrograph (Side Two) was used  to obtain =
darks, internal flats (in photoscan mode), wavelength calibrations and =
observations of standard star BD+28D4211.  This includes detector =
calibration, sensitivity monitoring, and wavelength monitoring.  The =
observations were executed as scheduled, and no anomalies were noted. 

   1.5 Completed FGS 6047 (Calibrating the Mass Luminosity Relation at the =
End of the Main Sequence)

       The FGSs were used to make astrometric observations of star GJ2005 =
as part of a study to determine its mass luminosity relationship.  The =
purpose is to measure the precise parallax and relative orbit of its faint =
companion.  The observations were completed as planned, and no problems =
were reported.

   1.6 Completed Two Sets of WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were reported.

   1.7 Completed FGS 6274 (Linking the HIPPARCOS to the Extragalactic =
Referance Frame)

       FGS #3 was used to make astrometeric observations of extra-galactic =
objects 0405-123IN, 340-REF, 341, REF, 342-REF, INCA221-28 and several =
other reference stars in order to help link the HIPPARCOS satellite =
reference frame to that of the HST.  The observations were completed as =
planned, and no anomalies were reported.

   1.8 Completed WF/PC-2 5996 (The Morphology of Field Galaxies at High =
Redshifts)

       The WF/PC-2 was used to make observations  of several field =
galaxies (FIELD-0302) in order to study their morphologies.  The =
observations were completed as planned, and no anomalies were reported.

   1.9 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images.  =
These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.10 Completed WF/PC-2 6250 (WF/PC-2 Cycle 5 Calibration: Internal =
Monitor)

       The WF/PC-2 was used to make a series of internal calibration =
observations.  Internal flats, biases, and K-spot calibration images were =
taken.  These observations are designed to monitor the health of the =
cameras.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.11 Completed WF/PC-2 5988 (Imaging Quasars in Rich Clusters)

       The WF/PC-2 was used to make observations of radio quasar 5C2.10 =
which is located in a rich galactic cluster.  There is evidence that =
quasars in rich clusters of galaxies evolve more quickly than quasars in =
poor environments.  The observations were completed as planned, and no =
problems were noted.

   1.12 Completed S/C 5582 (FOC/48 Monthly Activation (Camera Section =
Only): Cycle 4) 

       This proposal was executed as scheduled, and no anomalies were =
noted. 

   1.13 Completed GHRS/2 6249 (Observations of Interstellar Oxygen)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of star HD120324 in order to study =
interstellar oxygen in the line of sight to that star.  It was found =
previously that the oxygen abundance in the direction of Orion is only =
half of the solar abundance.  The observations were completed as =
scheduled, and no anomalies were noted.

   2.3 Operations Notes: 

       The new PRS TTAC system continues to be run in parallel with the =
opertional realtime system, with operations personnel monitoring and =
utilizing both systems.  No problems or differences were noticed, except =
for an instance of data inversion that was observed on the new system but =
not on the operational system.
