HUBBLE SPACE TELESCOPE
DAILY REPORT #1022

PERIOD COVERED: 0800 EST
Daily Status Report as of 328/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WFC 5013 (WF/PC Cycle 3 Calibration: WFC Flats Narrow. 2)

The Wide Field Camera was used to make Earth flat calibration images
to be used for flat fielding of WFC observations. The observations
used the narrow band filters, both with and without neutral density
filters. A total of four observations were received. One observation
was reported to be underexposed, and the others were okay.

1.2 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 executed as scheduled, and no problems were
reported.

1.3 Completed FOS/RD/FOC/96/HSP/POL/GHRS/2 5232 (Fall Heptathlon)

This proposal used each of the SIs along with the WFC and FGSs to
determine the focal plane and FGS stability, and the relative
positions of the SIs. All observations were made in fine lock. A
total of sixteen images were taken, and all were reported to look
normal.

1.4 Completed PC 4714 (WF/PC Cycle 2 Calibration: PC Internal Delta
Flats)

The Faint Object Camera was used to make eight internal flat
calibration images which will be used for the restoration of Earth
flat images, which were altered due to changes in quantum efficiency
which occurred after decontamination operations. The observations
was received and displayed in the OSS. Of the eight images, six were
reported to be okay. Two showed a dark steak, which may be more
prominent than usual.

1.5 Completed PC 5072 (WF/PC Cycle 3 Calibration: PC Flats Wide. 1)

Both the Wide Field Camera and the Planetary camera were used to
make 16 Earth Flat calibration exposures using the wide and medium
band filters. All sixteen observations were received and displayed
in the OSS. Eight images were reported to be okay, four were
saturated, and four were underexposed.

1.6 Completed FOS/BL 4952 (QSO Absorption System Snapshot Survey - Part
2 of 3: Cycle 3 High)

The Faint Object Spectrograph was used to make 2 observation of
quasar 0856+4649 to look for absorption lines at low redshift, and
also emission lines in the QSO's continuum. Both observations were
received and displayed. The onboard target acquisition was
successful, and the observations were reported to look okay.

1.7 Completed Three Sets of WFC 4713 (WF/PC Cycle 2 Calibration: WFC
Internal Delta Flats)

The Wide Field Camera was used to make a total of three internal
flat calibrations images. All three images were reported to be
normal.

1.8 Completed FOS/BL 5050 (Cycle 3 Internal Wavelength Calibration)

The Faint Object Spectrograph was used to make calibration spectra
for every detector/ grating combination through the 0.3" circular
and 0.1" paired apertures. The observations were monitored in the
OSS, and the data quality was assessed. No problems were reported.

1.9 Completed FOS/BL 4305 (A Critical Extension of the Interstellar
Polarization Curve: Cycle 3 High)

The Faint Object Spectrograph (Blue Side) was used to make
polarization light curves of the star HD204827 to study interstellar
dust grains. It is hoped to find a correlation between polarization
and wavelength. The observations were monitored in the OSS, and the
data quality was assessed. No anomalies were reported.

1.10 Completed 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.

1.11 Completed WFC/PC 4929 (WF/PC Cycle 2: Improved Dark Calibration)

The Planetary Camera was used to make two dark calibration images.
The two exposures lasted 1200 seconds each, and the camera was
pre-flashed before the observations. Both observations were reported
to be normal exposures.

1.12 Completed WFC 5019 (A Survey of the Giant Branch of the Bulge of
M-31 - Continuation of 2735)

The Planetary Camera was used to help make a survey of red giant
stars in the nuclear bulge region (aka, NGC-224-1) of galaxy M-31
(aka, the Andromeda Galaxy) to study the distribution and metal
abundances of these stars. This is a continuation of proposal 2735.
The OSS monitored the observations, and assessed the data quality.
No anomalies were reported.
