HUBBLE SPACE TELESCOPE
DAILY REPORT #1159

PERIOD COVERED: 0700 EST
Daily Status Report as of 165/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FOS/BL 5656 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor. 2: Flats Part 2)

The Faint Object Spectrograph (Blue side) was used to make
calibration observations of star HD207757 (aka, AG Pegasi) and
object NGC-188-225. A total of seven observations was received, and
have not yet been completely analyzed. However, some of the target
acquisition data was received in real-time. The peakups had maximum
counts in groups 1 and 3, but the counts were much lower than the
previous set using the old flight software and appeared to have
missed the target. At the present time no explanation has been
found.

1.2 Completed GHRS/1 5594 (GHRS Side 1 Sensitivity Monitor: Cycle 4)

The High Resolution Spectrograph (Side One) was used to make
calibration observations of star BD28D4211 to monitor the long-term
sensitivity of the system. A total of fourteen observations was
received, but not displayed due to lack of time. The target
acquisition was seen in real time and the target was in map 5 of the
5X5 spiral search, with a target search flux of 7135 counts. The
Small Science Aperture peakup (5X5) found the target at the eighth
dwell point with a target flux of 4259 counts. No anomalies were
noted.

1.3 Completed WF/PC-2 5568 (WF/PC-2 Cycle 4 Calibration: Decon)

The WF/PC-2 was used to make internal flat calibration
observations, K-Spots, and darks as part of a decontamination
operation. Six observations were received, but there was not enough
time to display them. No anomalies were noted.

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

The Faint Object Camera (f/96) was used to make calibration
observations of BPM16274. The first observations were received and
displayed in real-time. A corrective pointing maneuver was
successfully calculated, and uplinked to the spacecraft. The target
was placed at the fiducial point of the aperture. No anomalies were
noted.

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 executed as scheduled, and no anomalies were noted.

1.6 Completed WF/PC-2 5563 (WF/PC-2 Cycle 4 Photometric Calibration
Monitor 1: UV/OPT STD)

The WF/PC-2 was used to make photometric calibration images of
ultraviolet standard star GRW+70D582 and monitor the photometric
stability and quantum efficiency of the WF/PC-2. A Loss of Lock
(LOL) occurred during the observations (See Operations Note 2.4).
The observational data has not yet been received. The DOC is working
on a Line Outage Recorder (LOR) playback. Analysis is pending the
receipt of the data.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:


Scheduled Acquisitions : 5
Successful : 5
Scheduled Reacquisitions : 10
Successful : 10

A Loss of Lock (LOL) occurred at 165/0938Z near a
Day/Night transition. The Take Data Flag (TDF)
dropped and science data observations were lost.
Subsequence lock operations were successful.

2.2 FHST Updates:

Scheduled :11
Successful :11

2.3 Significant HSTARs: None

2.4 Operations Notes:

The HST observatory experienced a quiet day as each subsystem
reported nominal performance.

3.0 ANOMALY STATUS:

4.1 Significant New Anomalies: None

4.2 Significant Unresolved Anomalies: None

4.0 SIGNIFICANT FORTHCOMING EVENTS:

Nothing at this time.
