HUBBLE SPACE TELESCOPE
DAILY REPORT #1169

PERIOD COVERED: 0700 EST
Daily Status Report as of 179/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed 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-7331 to be used in
measuring the periods of Cepheid variable stars within this galaxy.
The images were received and displayed. They were reported to look
okay. The first three images encountered some recenterings.

1.2 Completed FOS/BL 5364 (The UV spectral Components in RE1938-461, The
Brightest ROSAT WFC disc)

The Faint Object Spectrograph (Blue Side) was used to make rapid
mode ultraviolet observations of the polar-type cataclysmic variable
star RE1938-461. Ten observations were received and displayed. They
all were reported to look good, although it will be necessary to
look at the tape recorded engineering data to be sure that the
target acquisitions were completely successful. One more observation
still remains on Science Tape Recorder #1, and will be analyzed
later.

1.3 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 executed as scheduled, and the data still remains on Science
Tape Recorder #1. It will be analyzed later.

1.4 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, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the
optical alignment, and to check for contamination. A total of eight
images was taken. They were reported to be nominal.

1.5 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 HEAO2106-0 and MARK896. The first
observation remains on Science Tape Recorder #1, and will be
analyzed later. The second observation was executed as scheduled,
and no anomalies were noted.

1.6 Completed WF/PC-2 5221 (The Vertical Structure of the Atmosphere of
Neptune)

The WF/PC-2 was used to make observations of the Planet Neptune to
study the structure and composition of the clouds and haze in the
upper regions of its atmosphere. The observations were executed as
scheduled, and no anomalies were noted.

1.7 Complete WF/PC-2 5427 (Calibration of Nearby Galaxy Type IA
Supernovae as Standard Candles)

The WF/PC-2 was used to make observations of nearby galaxy
NGC-4536-FI as part of an effort to find Cepheids in this galaxy
which has produced a Type I supernovae. The observations were
executed as scheduled, and no anomalies were noted.
