HUBBLE SPACE TELESCOPE
DAILY REPORT #1125

PERIOD COVERED: 0700 EST
Daily Status Report as of 116/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4)

The WF/PC-2 was used to make observations taken in parallel with the
prime science observations. Two images were received and displayed.
One was reported to have had a recentering event, and the other was
reported to be underexposed.

1.2 Completed GHRS/1 5276 (GHRS Side 1 Detector Calibration : Cycle 4)

The High Resolution Spectrograph was used to conduct a standard
detector test that will be used as part of the routine calibration
for the HRS. One normal dark exposure, and ten internal flats were
successfully received.

1.3 Completed WF/PC-2 5635 (WF/PC-2 Partial Filter Stepping Test)

The WF/PC-2 was used to conduct a partial filter stepping test. One
exposure was received, and it was reported to be underexposed.

1.4 Completed WF/PC-2 5404 (Narrow Band Imaging of Hydrogen-Poor
Planetary Nebulae: Cycle 4 High)

The WF/PC-2 was used to make narrow band images of the small
dynamical structure of the hydrogen-poor planetary nebula
IRAS15154. Two images were received and displayed. They were
reported to look fine

1.5 Completed FOS/RD 5535 (Cycle 4 Internal Wavelength Calibration)

The Faint Object Spectrograph was used to make internal calibration
observations to monitor the stability of the wavelength scale for
different gratings. Five observations were received and displayed.
They were reported to be satisfactory.

1.6 Completed Three Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration:
Internal Monitor 3: Darks)

The WF/PC-2 was used to obtain a 30-minute long, dark exposure
to provide ongoing calibration of the CCD dark current and to
monitor and characterize the evolution of hot pixels. One nominal
dark exposure was received.

1.7 Completed WF/PC-2 1070 (High Resolution Imaging of Radio Galaxies at
Large Redshift)

The WF/PC-2 was used to make deep images of radio galaxy 3C340.
Eight images were received and displayed. They all were reported to
be okay, except for occasional recenterings.

1.8 Completed Two Sets of WF/PC-2 5633 (Asteroid Shape and Duplicity)

The WF/PC-2 was used to make observations of asteroid 243-Ida. The
observations were executed as scheduled, and no anomalies were
noted.

1.9 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 for contamination. The observations were
executed as scheduled, and no anomalies were noted.

1.10 Completed FGS 5583 (Long Term Stability Monitoring of FGS3)

The Fine Guidance Sensor #3 was used to monitor the optical field
angle distortion by making astrometric observations of star OF55-REF
which is located in the open cluster M-35. The astrometric
observations were monitored, and no problems were seen in the
telemetry.

1.11 Completed WF/PC-2 5372 (HST Medium Deep Survey: Cycle 4 Medium, Low
Galactic Latitude)

The WF/PC-2 was used to make low galactic latitude observations
taken in parallel with the prime science observations. The
observations were completed as scheduled without apparent anomaly.

1.12 Completed WF/PC-2 5561 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor. 2: Flats)

The WF/PC-2 was used to make a visual flat calibration images to
monitor flat field stability and the stability of the
analog-to-digital converters. The observations was executed as
scheduled, and no anomalies were noted.

1.13 Completed FGS 5333 (Linking the HIPPARCOS to the Extragalactic
Reference Frame, BR12-23, Part 2)

The FGSs were used to obtain astrometric observations on star
INCA221-88 whose apparent position lies near an extragalactic
object. The observations were executed as scheduled, and no
anomalies were noted.

1.14 Completed WF/PC-2 5370 (HST Medium Deep Survey: cycle 4 Medium,
High Galactic Latitude)

The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations as part of a medium-deep
sky survey. The observations were executed as scheduled, and no
anomalies were noted.

1.15 Completed WF/PC-2 5415 (The Distance to the M-96 Galaxy Group:
Cycle 4 Medium)

The WF/PC-2 was used to make observations of Cepheid variable stars
within the galaxy UGC-5889 which itself is located in the M-96
galaxy cluster. The observations were executed as scheduled, and no
anomalies were noted.

1.16 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earthflats,
Large Set)

The WF/PC-2 was used to make a set of Earth flat calibration images.
The observations were executed as scheduled, and no anomalies were
noted.
