HUBBLE SPACE TELESCOPE
DAILY REPORT #1194

PERIOD COVERED: 0000Z
Daily Status Report as of 215/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and
Spiral Galaxies)

The WF/PC-2 was used to make observations of the core region of
galaxy
NGC-2090 to provide statistics on the nuclear cups, stellar condensations,
and
inner stellar disks and dust lanes. The observations were executed as
scheduled, and no anomalies were noted.

1.2 Completed Two Sets of WF/PC-2 5569 (WF/PC-2 cycle 4 Calibration:
Internal Flats)

The WF/PC-2 was used to make flat field calibration images with the
VIS lamp, and the internal source. The observations were completed as
planned, and no problems were reported.

1.3 Completed Two Sets of 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-4536-FI as part of an effort to find Cepheids in this galaxy which has
produced a Type I supernova. The observations were executed as scheduled,
and no anomalies were noted.

1.4 Completed Three Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration:
Internal Monitor 2: Darks)

The WF/PC-2 was used to obtain several 30-minute long, dark
exposures
to provide ongoing calibration of the CCD dark current and to monitor and
characterize the evolution of hot pixels. The observations were completed
as planned, and no problems were reported.

1.5 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor. 1)

The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the optical
alignment, and to check for contamination. The observations were completed
as
planned, and no anomalies were noted.

1.6 Completed FGS 4884 (High Speed Astrometry: A Search for Planetary
Companions to Low Mass Stars)

The FGSs were used to make observations of Barnard's star to look
for astrometric companions (i.e., a Jupiter-sized companion). The
observations were executed as scheduled, and no anomalies were noted.

1.7 Completed FOS/RD 5529 (Cycle 4 FOS Discriminator Test)

The Faint Object Spectrograph (Red Side) was used to run
discriminator tests to determine if the discriminator settings need
adjustment from the Cycle 3 Values. Dark, Internal Flat, and Wave
calibrations observations were taken. The observations were executed as
scheduled, and no anomalies were noted.

1.8 Complete WF/PC-02 5439 (The Calibration of White Dwarf Distance
Scale for Globular Clusters)

The WF/PC-2 was used to make observations of white dwarf WD126+734
to help use the cooling sequence of the white dwarf to determine distances.
The observations were executed as planned, and no problems were reported.

1.9 Completed FOS/BL/WF/PC-2 5494 (Stellar Winds of Massive Stars in
Nearby Galaxies)

The WF/PC-2 was used to make observations of one bright star
M31-OB78-2 in galaxy M-31 to learn more about the stellar wind, mass loss
rate, and abundances of the target star. The observations were executed as
scheduled, and no anomalies were noted.

1.10 Completed FOS/RD 5098 (UV Spectra of Low Redshift QSOs: Cycle 4
Observations)

The WF/PC-2 was used to make two ultraviolet images of the Low-Z
quasi-stellar object PG2302+029 to obtain images and spectra of the
surrounding galaxy. The observations were executed as scheduled, and no
anomalies were noted.

1.11 Completed GHRS/1 5595 (GHRS ECH-A Wavelength Monitor: Cycle 4)

The High Resolution Spectrograph was used to make wavelength
spectral
lamp calibration observations to measure the instrumental characteristics
of
the Echelle-A spectrograph. The observations were received and displayed in
the OSS. They were reported to look okay.

1.12 Completed WF/PC-2 5479 (Subarcsecond Structures in Nearby AGNs)

The WF/PC-2 was used to make snapshot observations of the nearby
active
galactic nuclei of NGC-3516 to study the interactions between the central
engine, the stars, and the interstellar matter in the AGN. The observations
were executed as scheduled, and no anomalies were noted.

1.13 Completed WF/PC-2 5603 (The Stellar Density Distributions in the
Centers of Galactic Globulars)

A single exposure was made with the WF/PC-2 of the central region in
globular cluster M-30 (aka,NGC-7099) to search for cusps in the stellar
density distribution. The observations were completed as planned, and no
problems were reported.

1.14 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earth Flats
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.
