                       DAILY REPORT #1594

PERIOD COVERED:  0000Z (UTC) 03/19/96 - 0000Z (UTC) 03/20/96

Daily Status Report as of 080/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed 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.

   1.2 Completed Two Sets of WF/PC-2 6352 (Dwarf Eliptical Galaxy =
Snapshots)

       The WF/PC-2 was used to survey VCC1876, from a sample of 30 dwarf =
eliptical galaxies.  The observations were completed as planned, and no =
anomalies were reported.

   1.3 Completed FGS 6051 (Dynamical Masses For The Stars in the Pre-Main =
Sequence Spectroscopic Class)

       The FGS were used to make astrometric measurements of the location =
of star STAR-04560 (aka, GSC2387+535) to measure its relative orbit in a =
pre-main sequence binary system.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.4 Completed 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.

   1.5 Completed WF/PC-2 6365 (A Snapshot Survey For Companions and =
Clusters around Wolf-Rayet Stars)

       The WF/PC-2 was used to make snapshot observations of Wolf-Rayet =
star WR153in order to look for companion stars and clusters.  Photometry =
was performed on the Wolf-Rayet star and associated stars.  The observatio=
ns were completed as planned, and no anomalies were reported.

   1.6 Completed GHRS/2 6850 (GHRS G270M Y Deflection Test)

       The High Resolution Spectrograph (Side Two) was used to make an =
internal wavelength calibration observation using grading G270M and lamp =
SC2 as part of a Y-deflection test.  The observations were completed as =
Scheduled, and no anomalies were noted.

   1.7 Completed WF/PC-2 6003 (The Evolution of Elliptical Galaxies in =
distant Clusters)

       The WF/PC-2 was used to make observations of elliptical galaxies =
in distant galactic cluster Gal-Clus-1 to study the evolution of the =
structure of these elliptical galaxies.  The observations were completed =
as planned, and no problems were reported.

   1.8 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.

   1.9 Completed FOS/RD 6019 (Supersonic Velocity Dispersion in Dwarf =
Nova Accretion Disks)

       The Faint Object Spectrograph (Red Side) was used to make spectrogr=
aphic observations of the dwarf nova OY-Car in order to study its =
supersonic velocity dispersion.  The intent is to nail down the physical =
support mechanism for its accretion disk of this short period eclipsing =
dwarf nova.  As documented in HSTAR 5537, near the beginning of this =
nine-hour proposal, at 079/2234Z, there was an FOS mode 2 target =
acquisition failure.  Otherwise, the observations were executed as =
scheduled, and any affects of the acquisition failure were not 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 on 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.
