PERIOD COVERED:  0000Z (UTC) 05/10/95 - 0000Z (UTC) 05/11/95

Daily Status Report as of 131/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral Galaxies: A
PC Snapshot Imaging)

       The WF/PC-2 was used to make observations of the core region of
galaxies NGC-4449, NGC-4281, NGC-4498, NGC-1336, and IC3115 to provide
statistics on the nuclear cusps, stellar condensations, and inner stellar
disks and dust lanes. The observations were executed as scheduled, and no
anomalies were noted. 

   1.2 Completed WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs)

       The WF/PC-2 was used to make snapshot observations of the nearby
active galactic nuclei of ESO353-G9 to study the interactions between the
central  engine, the stars, and the interstellar matter in the AGN. The
observations were executed as scheduled, and no anomalies were noted. 

   1.3 Completed WF/PC-2 5655 (WF/PC-2 Cycle 4 Calibration: Internal Monitor.
2: Flats Part 2)

        The WF/PC-2 was used to make a visual flat. The observation was
completed as planned, and no problems were reported. 

   1.4 Completed WF/PC-2 5981 (Calibration of Nearby Type IA Supernova as
Standard Candles: NGC-4639)

       The WF/PC-2 was used to make observations of Cepheid variable stars in
Galaxy NGC-4639 (which has produced a Type IA Supernova) to calibrate the
nova's absolute brightness so that it can be used as a standard candle for
distance measurements. The observations were executed as scheduled, and no
anomalies were noted.

   1.5 Completed WF/PC-2 5663 (WF/PC-2 Cycle 4: Photometric Calibration
Monitor: Fields Part 2)

       The WF/PC-2 was used to make observations of globular cluster NGC-5139
with various filters in order to check the photometric calibration of the
WF/PC-2. The observations were completed as planned, and no anomalies were
reported. 

   1.6 Completed GHRS/2 5466 (The Interaction Between Io and The Plasma
Torus)

        The High Resolution Spectrograph (Side Two) was used to make Echelle
spectrographic observations of the plasma torus which is a result of the
interaction of the planet Jupiter and its moon Io. Of particular interest is
the O II emission line at 2471 A0. The observations were completed and
scheduled, and no anomalies were reported.

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

       The WF/PC-2 was used to make snapshot images of radio galaxies 3C265.0
and 3C274.1 as part of a continuum survey and to study the galaxies'
morphology. The observations were executed as scheduled, and no anomalies
were noted.

   1.8 Completed WF/PC-2 6143 (WF/PC-2 Cycle 4 Photometric Calibration:
Smaller Set, Part II)

       The WF/PC-2 was used to make single CCD calibration observations of
standard star  GRW+70D582 to monitor the photometric stability and quantum
efficiency of the PC1 and WF3. The observations were executed as scheduled,
and no anomalies were reported.
