HUBBLE SPACE TELESCOPE

DAILY REPORT #1584

PERIOD COVERED: 0000Z (UTC) 03/05/96 - 0000Z (UTC) 03/06/96

Daily Status Report as of 066/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5924 (Nuclear Emission Line Region Associated =
with Compact Flat Spectrum)

The WF/PC-2 was used to make spectrographic observations of the =
nuclear emission region of galaxy NGC-984 to study its compact flat =
spectrum. There is evidence that this jet-produced AGN is powered by =
accretion disks feeding massive black hole. The observations were =
executed as schedule, and no anomalies were noted.

1.2 Completed FGS 6037 (Continuation of an Astrometric Search for =
Planetary Companions to Proxima-Cent)

The FGSs were used in the POS mode to make astrometric observations =
of the star Proxima-Cent and a sub-set of eight reference stars. This is =
to look for the presence of a planetary companion. The observations were =
executed as scheduled, and no anomalies were noted.

1.3 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.

1.4 Completed FGS 6049 (Monitoring the Size and Shape of Mira Type =
Stars)

The FGSs were used to make astrometric observations of the Mira =
class star HD847748 in order to study its size and shape during different =
phases of its pulsation cycle. The observations were completed as =
planned, and no anomalies were reported.

1.5 Completed WF/PC-2 6278 (Faint Clusters of Galaxies(WC09): Cycle 5)

The WF/PC-2 was used to make two color image observations of the =
faint galactic cluster GAL-CLUST-13 which is at a redshift of 0.72 . The =
primary objective of this study is to investigate the color and =
morphological evolution of this galactic cluster. The observations were =
executed as scheduled, and no anomalies were noted.

1.6 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.

1.7 Completed GHRS/1 6081 (Understanding the Simplest Symbiotic =
Systems)

The High Resolution Spectrograph (Side One) was used to make =
proof-of-concept spectrographic observations of the star HD117970 (aka, RW =
Hya) in order to obtain an understanding of this simplest symbiotic binary =
systems. One component is a red giant, and the other is a hot star. The =
observations were completed as planned, and no anomalies were noted.

1.8 Completed GHRS/1 6083 (The Expanding Chromosphere of a Star)

The High Resolution Spectrograph (Side One) was used to make =
Lyman-Alpha emission spectrographic observations of the A class star =
HD187642 in order to study its expanding chromosphere. The observations =
were completed as planned, and no anomalies were reported.

1.9 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS =
Galaxy Sample-Part 1 High)

The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous IRAS galaxy IR19297-04. These data will be searched for =
multiple cores, which imply a merger has occurred, and for starburst =
regions. The observations were executed as scheduled, and no anomalies =
were noted.
