HUBBLE SPACE TELESCOPE
DAILY REPORT #1095

PERIOD COVERED: 0700 EST
Daily Status Report as of 074/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies)

The WF/PC-2 was used to make snapshot images of radio galaxies
3C330.0 and 3C228.0 as part of a continuum survey and to study the
galaxies' morphology. Four images were received and displayed. All
four were reported to look okay.

1.2 Completed WF/PC-2 5565 (WF/PC-2 Cycle 4: Photometric Calibration
Monitor: Fields)

The WF/PC-2 was used to make photometric calibration images by
taking images of the large globular cluster Omega Centauri (aka,
NGC-5139) to help determine astrometric and optical stability of the
WF/PC-2. The OSS monitored the observations, and assessed the data
quality. A total of ten observations were monitored. No anomalies
were noted.

1.3 Completed WF/PC-2 5612 (SMOV WF/PC-2 Decontamination)

The WF/PC-2 was used to do decontamination operations. Observations
of standard A+81D266, and K-Spot observations were also taken. A
total of eight observations were monitored and displayed. The
internal and external observations were all nominal.

1.4 Completed WF/PC-2 4709 (WF/PC-2 Internal Monitor)

The WF/PC camera was used to make a series of routine ultraviolet
flat calibration images to monitor the instrument's performance. The
observations were monitored in the OSS, and the data quality was
assessed. 26 observations were received and displayed. One
observations was reported to have been missing one group from a
partial STR dump. The version of the file from the dump with the
rest of the data appeared to be intact, but the first group could
not be displayed.

1.5 Completed FGS 4884 (High Seed Astrometry: A Search for Astrometric
Companions to Low Mass Stars)

The FGSs were used to make observations of Bernard's star to look
for astrometric companions (i.e., a Jupiter-sized companion). The
first four observations were monitored, and appeared nominal. The
remainder of the observations occurred during LOS, and will be
analyzed later.

1.6 Completed Three Sets of WF/PC-2 5090 (Large Area: Multicolor Survey:
Cycle 4)

The WF/PC-2 was used to make deep exposure images of fields #1416
and #1418 as part of a large area, high galactic latitude,
multicolor
sky survey to learn more about the distribution of galaxies, their
morphology, distribution in magnitude and redshift, and evolution of
galactic luminosity function and colors. Eight images were received
and displayed. The first six were reported to be nominal. The last
two were reported to have had recentering events occur during the
observations.

1.7 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. A total of ten images
were taken. Six were received and displayed, and four remain on the
science tape recorder. No anomalies were noted.

1.8 Completed WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor 3: 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 executed as scheduled, and no anomalies were
noted.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 7
Successful : 7
Scheduled Reacquisitions : 8
Successful : 8

2.2 FHST Updates:

Scheduled :17
Successful :17

2.3 Significant HSTARs: None

2.4 Operations Notes:

SMOV activities performed last week included: flat fields
calibration, decontamination monitoring, and the completion of fine
alignment and focus operations with the final SMOV adjustment of the
articulated fold mirrors for WF/PC-2; and the repeat of FOS/FGS fine
alignment of the FOS/Red large apertures. SMOV functions remaining
to be conducted are: FOS/FGS fine alignment of small apertures, FOS
plate scale, GHRS early release observation (ERO), and a repeat of
the FOS ERO to correct a target acquisition/pointing problem. With
the exception of the last item, all SMOV activities are scheduled
for completion before or during the last week of March.

For the last 24 hours, there have been no reported problems with
any SMOV operation or with any HST subsystem.
