PERIOD COVERED:  0000Z (UTC) 05/16/95 - 0000Z (UTC) 05/17/95

Daily Status Report as of 137/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal Monitor.
1) 

       The WF/PC-2 was used to make several internal dark, bias, K-Spot, and
flat calibration observations to monitor the CCD camera electronics, the
optical alignment, and to check for contamination. The observations were
completed as planned, and no anomalies were noted. 

   1.2 Completed Two Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration:
Internal Monitor 3: Darks)

       The WF/PC-2 was used to obtain several 30-minute long, dark exposures
to provide ongoing calibration of the CCD dark current and to monitor and
characterize the evolution of hot pixels. The observations were executed as
scheduled, and no anomalies were noted. 

   1.3 Completed Three Sets of WF/PC-2  5476 (Continuum Snapshots of 3CR
Radio Galaxies) 

       The WF/PC-2 was used to make snapshot images of radio galaxies
3C179.0, 3C275.0 and 3C318.1 as part of a continuum survey and to study the
galaxies' morphology. The observations were executed as scheduled, and no
anomalies were noted.

   1.4 Completed GHRS/2 6288 (Eclipse Mapping of the Chorospheric and
Transition Region Structure)

       The High Resolution Spectrograph (Side Two) was used to make
observations of star HD50337 (aka, HR2554) during the eclipse of its class A1
dwarf secondary star by the class G6 II primary star. The dwarf secondary
star will be used as a light source to observe the plasma absorption lines in
the outer atmosphere of the primary star. The observations were executed as
scheduled, and no anomalies were noted.

   1.5 Completed GHRS/2 5093 (Composition of Gas in Individual Interstellar
Clouds: Cycle 4 Observation)
       The High Resolution Spectrograph (Side Two) was used to obtain the
spectra of a the early type star HD219188 to study interstellar clouds which
lie along the line of sight to the star. The observations were completed as
planned, and no anomalies were reported.
