HUBBLE SPACE TELESCOPE
DAILY REPORT #935

PERIOD COVERED: 0800 EST
Daily Status Report as of 204/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FGS 4893 (Orbital Motions of Close Binary Stars Cycle 3
High)

Fine Guidance Sensor #3 was used to make astrometric observations of
the binary star system GLIESE-568 to obtain its orbital elements.
These observations are important since most of the estimates of
stellar mass are made by observing elements of these systems. The
astrometry was monitored and no problems were seen in the telemetry.

1.2 Completed Three Sets of PC/WFC 4809 (Cycle 2 : WF/PC PSF Calibration
Proposal)

The Planetary Camera was used to make three point spread function
calibration images of standard star HD144470. The OSS monitored the
observations and assessed the data quality. All three observations
were displayed. They all looked okay, but the first observation had
a cosmic ray hit across the image's point spread function.

1.3 Completed PC 4712 (WF/PC Cycle 2 Calibration: Measles Monitor)

The Planetary Camera was used to make three Earth Calibration Flat
images to monitor a form of contamination known as measles. The
observations used filter F517N, both with and without filter F122M.
The first two observations were okay, and the third was reported to
be saturated.

1.4 Uplinked Updated Ephemeris Tables, Per MOSES 2871

1.5 Completed PC 4521 (Asteroid Shape and Duplicity - Cycle 3 High)

The Planetary Camera was used to make three snapshot images of the
large asteroid AST-709-FRIN to look for possible satellites, shapes,
and albedo variations. All three observations were received and
displayed, but they showed no target. It would appear that the
telescope was not correctly pointed for this moving target.

1.6 Completed FOS/RD/BL 4396 (QSO Absorption System Snapshot Survey -
Part 1 of 3: Cycle 3 High)

The Faint Object Spectrograph (Red Side) was used to make two
spectrographic observations of quasar 0052+2509 and 0145+3839 to
look for absorption line systems at low red shift, emission lines,
and to study the QSO's continuum. The observations was received in
real time. The science observations were reported to show a good
spectrum.

1.7 Completed FOS/BL 4953 (QSO Absorption System Snapshot Survey -
Part 3 of 3: Cycle 3 High)

The Faint Object Spectrograph was used to make two observations of
quasar 1701+6102 to look for absorption lines at low redshift, and
also emission lines in the QSO's continuum. The observations were
executed as scheduled, and the spectral observations were reported
to look okay.

1.8 Completed PC 5014 (WF/PC Cycle 3 Calibration: PC Flats Narrow. 2)

The Planetary Camera was used to make standard Earth calibrations
images for flat fielding of PC observations. Medium and narrow
filters were used, with and without neutral density filters. The
observations were not monitored closely, but were seen executing
(i.e., shutter open) as expected.

1.9 Completed FOS/BL/RD 4976 (UV Rotation Light Curves for Pluto, and
Charon's UV Spectrum - Split)

The Faint object Spectrograph was used to make a TALED exposure
subsequent to other spectral observations of the planet Pluto and
its moon Charon. After a corrective SIP maneuver was uplinked to the
spacecraft, spectral observations were made of the planet Pluto. The
observations were executed in fine lock. No problems were reported.

1.10 Completed WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal
Monitor)

Rapid Internal Monitoring observations were made with both the Wide
Field Camera and the Planetary Camera using filter F555W to look for
new forms of contamination (i.e. daises and measles), and the
possible return of quantum efficiency hysteresis. The observations
were monitored in the OSS, and the data quality was assessed. No
problems were reported.
