PERIOD COVERED:  0000Z (UTC) 02/15/95 - 0000Z (UTC) 02/16/95

Daily Status Report as of 047/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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 dark calibration image. The
observation was completed as planned, and no problems were reported. 

   1.2 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 galaxy
NGC-4378 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. 

   1.3 Completed WF/PC-2 5764 (WF/PC-2 Cycle 4 Calibration: Internal Flats -
Repeat)

       The WF/PC-2 was used to make internal flat calibration images using
the VIS lamp and internal sources. The observations were executed as
scheduled, and no anomalies were noted.

   1.4 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance
Scale: Cycle 4 High)

       The WF/PC-2 was used to make images of galaxy NGC-2090 to be used in
measuring the periods of Cepheid variable stars within this galaxy. The
observations were completed as planned, and no anomalies were noted.

   1.5 Completed FGS 5135 (Extragalactic Astrometry and Astrophysics, FT0-11,
Part 1 of Two)

      The FGSs were used to make astrometric observations of a set of stars
(i.e., 0818-128IN, 1420-REF, 1422-REF, and INCA221-44) to obtain data needed
to measure the HIPPARCOS reference frame with respect to the extragalactic
reference frame. The observations were executed as scheduled, and no
anomalies were noted. 

   1.6 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4) 

       The WF/PC-2 was used to make observations taken in parallel with the
prime science observations. This is part of a survey to take pictures of a
large number of fields within 30 degrees of the galactic plane. The
observations were completed as planned, and no problems were reported.

   1.7 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. 

   1.8 Completed FOS/BL 5674 (Ultraviolet Eclipse Mapping of the Accretion
Flow in Binary Stars)

       The Faint Object Spectrograph (Blue Side) was used to make ultraviolet
spectrographic observations of eclipsing binary star EX-Hya to map its
accretion flow. This binary system has a white dwarf star which is accreting
matter from its companion star. The observations were completed as planned,
and no anomalies were reported.

   1.9 Completed WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4 Medium, High
Galactic  Latitude) 

       The WF/PC-2 made a series of observations of high latitude objects as
part of a medium deep sky survey. The observations were taken in parallel
with other prime science observations. The observations were completed as
scheduled, and no anomalies were noted.

   1.10 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 NGC-5135 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.
