HUBBLE SPACE TELESCOPE
DAILY REPORT #1131

PERIOD COVERED: 0700 EST
Daily Status Report as of 124/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5369 (HST Medium_Deep Survey: Cycle 4 Medium: High
Galactic Latitude)

The WF/PC-2 made an observation of high latitude objects as part of
a medium deep sky survey. The observation was taken in parallel with
other prime science observations, and it was received and displayed.
No anomalies were noted.

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

The WF/PC-2 was used to make images of galaxies NGC-5457-FL, and
NGC-4321 to help establish the Hubble constant to an accuracy of
better than 10% by measuring the periods of Cepheid variable stars
within the galaxies. The first image was received and displayed, and
it was reported to be okay, except for some recentering. The second
observation still remains on the Science Tape Recorder #3, and will
be analyzed later. No anomalies were noted.

1.3 Completed GHRS/2 5591 (GHRS Side 2 "Locate= Extended" Test: Cycle
4)

The High Resolution Spectrograph was used to test new software that
will allow the use of more than the two standard diodes during the X
balancing in the locate phase of the target acquisition. The
observations were received and examined. The target was poorly
centered, or absent, in all of the images. Further analysis is
needed to determine the success of these observations.

1.4 Completed WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies)

The WF/PC-2 was used to make snapshot images of radio galaxy 3C270.0
as part of a continuum survey and to study the galaxy's morphology.
Two images were received and displayed. Both were reported to look
okay.

1.5 Completed FOS/BL 5579 (Cycle 4 Test: To Determine FOS Polarimetry
Mode)

The Faint Object Spectrograph (Blue Side) was used to make internal
calibration observations of its polarization capabilities. Six
observations were executed as scheduled. They all were received and
displayed. No anomalies were noted.

1.6 Completed WF/PC-2 5454 (Ellipticals with Kinematically Distinct
Cores: cycle 4 Medium)

The WF/PC-2 was used to make an observation of the small elliptical
galaxy NGC-4365 which contains a massive core which is kinematically
distinct from the rest of the galaxy. The observation was executed
as scheduled, and no anomalies were noted. The image was reported
to look fine.

1.7 Completed WF/PC-2 5238 (Asteroids (WC16): Cycle 4)

The WF/PC-2 was used to make observations of the asteroid
18-MELPOME. The observations were executed as scheduled, and the
science data remains on Science Tape Recorder #3. It will be
analyzed later. No anomalies were noted.

1.8 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-4818. The
observations were executed as scheduled, and the science data
remains on Science Tape Recorder #3. It will be analyzed later. No
anomalies were noted.

1.9 Completed Two Sets of 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. The observations were
executed as scheduled, and no anomalies were noted.

1.10 Completed WF/PC-2 5415 (The Distance to the M-96 Galaxy Group:
Cycle 4 Medium)

The WF/PC-2 was used to make observations of Cepheid variable stars
within the galaxy NGC-3368 which itself is located in the M-96
galaxy cluster. The observations were executed as scheduled, and no
anomalies were noted.

1.11 Completed WF/PC-2 1070 (High Resolution Imaging of Radio Galaxies
at Large Redshifts)

The WF/PC-2 was used to make deep images of radio galaxy 3C226. The
observations were executed as scheduled, and no anomalies were
noted.
