Daily Status Report as of 156/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5663 (WF/PC-2 Cycle 4: Photometric Calibration
Monitor: Fields Part 2)

The WF/PC-2 was used to make observations of globular cluster NGC-5139
with various filters in order to check the photometric calibration of the
WF/PC-2. The observations were completed as planned, and no anomalies were
reported.

1.2 Completed FOS/BL 5492 (Detection of the Intergalactic Medium Using
Gunn-Peterson HEII304A Absorption Line)

The Faint Object Spectrograph (Blue Side) was used to make
spectrographic observations of Quasi-Stellar Object QSO-133647 to search for
the redshifted 304A line (absorption) of He II. The observations were
completed as scheduled, and no anomalies were noted.

1.3 Completed Two Sets of WF/PC-2 6251 (Medium Deep Survey - Crafting
Test)

The WF/PC-2 was used in this continuation of the medium deep survey.
The proposal is targeting rare objects (lenses, peculiar galaxies, faint
stars) and sources related to the faint blue galaxy problem. This
observation was completed with no reported problems.

1.4 Completed FOS/BL 6146 (FOS Location of Spectra and Aperture - Part 2)

The Faint Object Spectrograph (Blue Side) was used to conduct a test to
determine the repeatability of positioning the filter-grating wheel. All
observations were internal. A wave length calibration image was also taken.
All observations were executed as scheduled, and no anomalies were noted.

1.5 Completed WF/PC-2 5411 (The Circumnuclear regions of Seyfert Galaxies:
Cycle 4 Medium)

The WF/PC-2 was used to make observations of the circumnuclear regions
of Seyfert Galaxy NGC-5643. Filters were used to isolate several prominent
emission lines, as well as their adjacent continua. The observations were
executed as scheduled, and no anomalies were noted.

1.6 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.

1.7 Completed WF/PC-2 5205 (Disk Around Main Sequence Stars)

The WF/PC-2 was used to make observations of star Vega (aka,
HD172167), which was found to have an infrared excess by IRAS, to try and
detect a circumstellar disk. The observations were completed as planned, and
no problems were reported.

1.8 Completed WF/PC-2 5981 (Calibration of Nearby Type IA Supernova as
Standard Candles: NGC-4639)

The WF/PC-2 was used to make observations of Cepheid variable stars in
Galaxy NGC-4639 (which has produced a Type IA Supernova) to calibrate the
nova's absolute brightness so that it can be used as a standard candle for
distance measurements.The observations were executed as scheduled, and no
anomalies were noted.

1.9 Completed WF/PC-2 6142 (WF/PC-2 Cycle 4 Calibration: Earth Flats,
Smaller Set Part II)

The WF/PC-2 was used to make Earth Flat calibration images for the
ultraviolet and narrow-band filters to correct for the telescope's
illumination pattern. The observations were executed as scheduled, and no
anomalies were noted.

1.10 Completed GHRS/1 5826 (Diffuse Ionized Gas Around Leo I)

The Goddard High Resolution Spectrograph (Side 1) was used to obtain
spectra of QSO 1008+1319 behind the Leo I dwarf galaxy. The QSOs were used
as probes to search for highly ionized gas in the outskirts of the dwarf.
The kinematics of the gas will also be determined. The proposal completed
with no reported errors.

1.11 Completed WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral Galaxies:
A PC Snapshot Imaging)

The WF/PC-2 was used to make observations of the core region of galaxy
NGC-1379 to provide statistics on the nuclear cusps, stellar condensations,
and inner stellar disks and dust lanes. The observations were executed as
scheduled, and no anomalies were noted.

1.12 Completed FOC/96 5526 (FOC UV Throughput Monitoring: Cycle 4)

The Faint Object Camera (f/96) was used to make calibration
observations of ultraviolet standard star BPM16274 to monitor the
ultraviolet throughput of the HST-FOC. The observations were executed as
scheduled, and no anomalies were noted.

1.13 Completed WF/PC-2 5568 (WF/PC-2 Cycle 4 Calibration: Decontamination)

The WF/PC-2 was used to make an internal flat field calibration
observation using the VIS lamp and the internal source as part of
decontamination operations. The observations were completed as planned, and
no problems were reported.

1.14 Completed Two Sets of WF/PC-2 6252 (GTO Pure Parallel Program - Cycle
4 Crafting Test.

This parallel program uses the WF/PC-2 and target fields at galactic
latitudes above 10 degrees. Galactic star counts and the structure of the
galactic halo will be studied. The observation completed as planned, and no
problems were reported.

1.15 Completed COSTAR/FOC 5762 (FOC Point Spread Function Monitoring:
Cycle 4)

The Faint Object Camera (f/96) was used to make an image of an
ultraviolet standard star BPM16274 in order to monitor the point-spread
function of the HST-COSTAR-FOC channel. The observations were executed as
scheduled, and no anomalies were noted.

1.16 Completed FOC/96 5301 (Structure and Populations of Globular
Clusters)

The Faint Object Camera (f/96) was used to make observations of the
large globular cluster NGC-5139 to make images of its core and two fields
farther from the center. The observations were executed as scheduled, and no
anomalies were noted.

1.17 Completed WF/PC-2 5463 (Buried QSOs in IRAS-Selected Ultra luminous
AGNs)

The WF/PC-2 was used to make observations of the luminous active
galactic nuclei of galaxy IRAS1334+2 to try and resolve the polarized
scattering regions in its core. The observations were completed as planned,
and no anomalies were reported.

1.18 Completed FOS/RD 5685 (Geometry and Generalization of the Reflected
Light Model for Seyfert Galaxies)

The Faint Object Spectrograph (Red Side) was used to make observations
the spectrum of polarized light near the nucleus of Seyfert galaxy (Type Two)
NGC-7674. The observations were executed as scheduled and no anomalies were
reported.
