HUBBLE SPACE TELESCOPE
DAILY REPORT #830

PERIOD COVERED: 0800 EST
Daily Status Report as of 055/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of FOS/BL 3545 (Evolution of Ultraviolet Spectra
in Early Type Galaxies)

The Faint Object Spectrograph was used to make four spectral
observations of early type galaxy 55W037. It observations was made
in parallel with the prime science observation. All four
observations were executed in course track. They were received and
displayed in the OSS. They were all reported to look good.

1.2 Completed WFC/PC 4109 (WF/PC Calibration: Rapid Internal Monitor)

Both the wide Field Camera and the Planetary Camera were used to
make internal flat observations to look for new forms of
contamination (i.e., measles and daisies), and the return of quantum
efficiency hysteresis. Both images were received and examined in the
OSS. They were reported to look normal.

1.3 Completed Two Sets of PC 4714 (WF/PC Calibration: PC Internal Delta
Flats)

The Planetary Camera was used to make a total of three internal
delta flat images. These images will be used for the restoration of
Earth flats, which were are altered due to changes in quantum
efficiency which occur after WFPC decontamination operations. All
three images were displayed, and reported to look okay.

1.4 Completed WFC 4713 (WF/PC Calibration: Internal Delta Flats)

The Wide Field Camera was used to take one internal flat
observation. The image was displayed in the OSS, and was reported to
look okay.

1.5 Completed PC 3769 (Spectra of Inner Coma of Comet Chrion)

The Planetary Camera was used to make 13 observations of the
comet/object Chiron to study the inner coma region, and dust near
the edge of its exopause. The first nine observations were received
and displayed. They were reported to look okay. The next four
observations were executed in course track. These were point spread
function observations and the engineering telemetry rate was only 4K
for these observations. The observations were reported to look okay,
however, they were filed as being bad because the engineering
telemetry was in the low data rate.

1.6 Completed GHRS/2 3862 (Excitation of Atmospheres of Planetary
Satellites)

The High Resolution Spectrograph was used to make eight spectral
observations of Jupiter's moon Io while it entered the planet's
shadow. All eight observations were received and where possible
displayed. The onboard target acquisition was successful. The
spectrum was reported to look normal.

1.7 Completed Two Sets of FOS/RD 4784 (Transition Comets: UV Search for OH)

The Faint Object Spectrograph was used to make two observations of
the asteroid HIDALGO looking for OH emission lines at 3085 A0. All
three observations were received and displayed. The first
observation was the onboard target acquisition. It was successful.
The second was the ultraviolet spectral observation. It was reported
to look normal.

1.8 Completed PC 3230 (PC PSF and Focus Monitoring 2)

The Planetary Camera was used to make point spread function
observations and focus change observations using standard star
SAO62896. These changes may have been caused by desorption or other
changes in the WFPC system. The observations were executed as
scheduled, and no problems were reported.

1.9 Initiated HSP/UV1 4209 (HSP Detector Sensitivity Test)

Observations were initiated using the High Speed Photometer to
measure the sensitivity of the four HSP Image Detector Tubes. The
calibration source is standard star VID998. The observations are
currently under way, and no problems have been reported.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 6
Successful : 6
Scheduled Reacquisitions : 9
Successful : 9
Losses of Lock : 0

2.2 FHST Updates:

Scheduled : 11
Successful : 11

2.3 Significant HSTARs: None

2.4 Operations Note:

A special FGS #2 analysis and review meeting to study the star servo
A anomaly was held yesterday at GSFC (Tuesday, Feb. 23,1993). This
meeting lasted all day and included experts from both government and
industry on bearings, motors, and servos. The meeting will continue
this afternoon (Wednesday, Feb. 24) at 1 p.m.
