HUBBLE SPACE TELESCOPE
DAILY REPORT #998

PERIOD COVERED: 0800 EST
Daily Status Report as of 294/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed PC 4904 (The Nuclei of Nearby S0 and Spiral Galaxies -
IIIA Snapshot Image)

The Planetary Camera was used to make one observations of the
low-red-shift galaxy NGC-1527 to study its surface brightness
profile, identify sub-arc-second scale condensations, find point
sources, and look for gasious disk and dust lanes. The observation
was executed without problems. The data was received and displayed,
and it was reported to look fine.

1.2 Completed PC 4308 (Snapshot Survey for Companions to Planetary
Nebula - Cycle 3 High)

The Planetary Camera was used to make an observation of the central
region of planetary nebula NGC-7009. It is possible that the central
star in a double star. The observations was received and displayed
in the OSS, the data was reported to look very good.

1.3 Completed HSP/UV2 5070 (Optical and Ultraviolet Observations of
Radio Galaxies - Cycle 2 High)

The High Speed Photometer was used to make observations of a pulsar
which is located in the Large Magellanic Cloud. The UV2 detectors
were used, and onboard target acquisition were used on a offset
star. The Sample time was 0.0003 second, and the total observation
time was about one hour. The OSS monitored the observations, and
assessed the data quality. The target acquisition images showed no
clear evidence of the star. It was not certain that the target was
actually acquired. The science observations were reported to be
weak.

1.4 Completed WFC 3589 (Parallel High Resolution Imaging of Defuse
Objects in the Magellanic Clouds)

The Wide Field Planetary Camera was used to make observations of the
nebulous object LMC-N158-P which is located in the Large Magellanic
Cloud. This observations was take in parallel with the prime science
observation. Am emission line filter and nearby continuum filter
were used. Two image were received and displayed. They both were
reported to look okay.

1.5 Completed Two sets of WFC/PC 5026 (WF/PC Cycle 3 Calibration: Rapid
Internal Monitor)

The Wide Field Camera and the Planetary Camera were used to make
internal flat calibration images. These images will be used to look
for measles and daisies (i.e., different forms of contamination),
and to monitor scattered light. The observations were executed as
scheduled, and no problems were reported. Three observations were
received and displayed. All three were reported to look normal.

1.6 Uplinked Updated Ephemeris Tables, Per MOSES 2871

1.7 Completed PC 4903 (The Nuclei of Nearby S0 and Spiral Galaxies -II A
PC Snapshot Imaging)

The Planetary Camera was used to make snapshot images of the
low-redshift galaxy IC1919 to study its surface brightness, identify
sub-arcsecond condensations, look for point sources, and look for a
stellar or gaseous disk and dust lanes. The observation was received
and displayed in the OSS. The observations was reported to look
okay.

1.8 Completed PC 4929 (WF/PC Cycle 2 - Improved Dark Calibration)

The Planetary Camera was used to make one dark calibration image.
The exposures lasted 1200 seconds each, and the camera was
pre-flashed before the observation. The observation was reported to
be a normal exposures.

1.9 Completed FOS/BL 5255 (Multiwavelength Observations of the Flares
and Oscillations of AE AQR)

The Faint Object Spectrograph (Blue Side) was used to make
ultraviolet observations of the cataclysmic variable star AE
Aquarii. The binary pair has an orbital period of 9.88 hours. The
onboard target acquisition was monitored in real-time. Inspection of
the science and engineering data show that the target acquisition
was successful. No problems were reported.

1.10 Completed WFC 4381 (HST Medium - Deep Survey - Cycle 3)

The Wide Field Camera was used to make two set of medium-deep high
latitude sky survey observations taken in parallel with the prime
science observations. The observations were executed as scheduled,
and no problems were reported.
