HUBBLE SPACE TELESCOPE
DAILY REPORT #1148

PERIOD COVERED: 0700 EST
Daily Status Report as of 147/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5561 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor. 2: Flats)

The WF/PC-2 was used to make ultraviolet and visual flat
calibration images to monitor flat field stability and the stability
of the analog-to-digital converters. The ultraviolet flat was
reported to show "worms", and the other five observations were
reported to be saturated.

1.2 Completed WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor 3: Darks)

The WF/PC-2 was used to obtain two 30-minute long, dark exposures
to provide ongoing calibration of the CCD dark current and to
monitor and characterize the evolution of hot pixels. Both
observations were received and displayed in the OSS. They both were
reported to look nominal.

1.3 Completed FOS/RD 5536 (Cycle 4 FOS Wavelength Calibration:
Internal/External Offsets)

The Faint Object Spectrograph (Red Side) made both internal and
external wavelength calibration observations. NGC-6833 was the
external source. The baseline guide-star acquisition achieved fine
lock before a LOS. The first peakup and most of the second one
occurred during LOS. No anomalies were noted. Most of the data still
remains on Science Tape Recorder #3, and will be analyzed later.

1.4 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. The observation was reported
to be nominal. Other observations were taken as scheduled, and the
data remains on Science Tape Recorder #3.

1.5 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 UGC-5889 which itself is located in the M-96
galaxy cluster. This is to help determine the distance to this
galactic group, and to improve the determination of the Hubble
constant. The observations were executed as scheduled, and no
anomalies were noted.

1.6 Completed 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-4496-A-F as part of an effort to find Cepheids which have
produced type I supernovae. The observations were executed as
scheduled, and no anomalies were noted.

1.7 Completed WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs)

The WF/PC-2 was used to make observations to study the nearby active
galactic nuclei of MARK-1210. The observations were executed as
scheduled, and no anomalies were noted.


1.8 Completed WF/PC-2 5208 (Star Formation Histories and Stellar
Populations in the Local Group)

The WF/PC-2 was used to make observations of the Large Magellanic
Cloud-Halo as part of a program to study stellar populations in the
outer regions of galaxies. The observations were executed as
scheduled, and no anomalies were noted.
