HUBBLE SPACE TELESCOPE
DAILY REPORT #1135

PERIOD COVERED: 0700 EST
Daily Status Report as of 130/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Three sets of WF/PC-2 5375 (High Resolution Images of
Virgo Galaxies With Kinematically Distance Cores)

The WF/PC-2 was used to make observations of galaxies NGC-4450,
NGC-4526, and NGC-4569 which are located in the Virgo Cluster. The
first two observations were received and displayed in the OSS. They
both contained six images, and were reported to be nominal. The
third set of observations were executed as scheduled, and no
anomalies were noted.

1.2 Completed GHRS/1 5417 (A Search for the Physical Processes
Responsible for the Jovian Equator....)

The High Resolution Spectrograph (Side One) was used as part of a
program to observe atomic hydrogen emission at different latitudes
and longitudes on the planet Jupiter. A total of five images were
received and displayed. They were reported to be nominal. A wave
calibration and sky background observations were made.

1.3 Completed Three Sets of WF/PC-2 5397 (Determination fo the
Extragalactic Distance Scale: Cycle 4 High)

The WF/PC-2 was used to make images of galaxy NGC-4321 to be used to
measure the periods of Cepheid variable stars within the galaxies.
Two images were received and displayed. Both were nominal. There
were some reported recenterings. A subsequent observation of galaxy
NGC-5457-FL remains on Science Tape Recorder #1, and will be
analyzed later.

1.4 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earthflats,
Large Set)

The WF/PC-2 was used to make a set of Earth flat calibration images
using different filters in order to construct high quality flat
fields of the OTA illumination pattern. A total of eight images were
received and displayed. The SI reported some FHST updates failures
(See Section 2.1), but no other anomalies. Two images were nominal,
and the others were underexposed.

1.5 Completed Two Sets of 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 galaxy NGC-4526. The
observations were executed as scheduled. Two images were received
and displayed. they were reported to be nominal. Observations of
galaxy NGC-4448 still remain on Science Tape Recorder #1, and will
be analyzed later.

1.6 Completed Two Sets of WF/PC-2 5481 (Ages of the Outermost Globular
Clusters: The Formation of the Galactic...)

The WF/PC-2 was used to make observations of a globular cluster
known as PAL-4-NORTH. One observations was received and displayed.
It was reported to be nominal. More data still remains on Science
Tape Recorder #1, and will be analyzed later.

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

The WF/PC-2 was used to make several internal bias calibration
observations. The observations were executed as scheduled, and no
anomalies were noted.
