HUBBLE SPACE TELESCOPE

DAILY REPORT #1537

PERIOD COVERED: 0000Z (UTC) 12/14/95 - 0000Z (UTC) 12/15/95

Daily Status Report as of 349/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Three Sets of WF/PC-2 6183 (WF/PC-2 Cycle 5 Calibration: =
Decon)

The WF/PC-2 was used to make some internal flat, K-spot, and dark =
calibration images. The purpose is to define decontamination procedures =
to be run during Cycle 5. The calibration observations were completed as =
scheduled, and no anomalies were reported.

1.2 Completed WF/PC-2 5834 (Distant Comet Nucleus Sizes)

The WF/PC-2 was used to make observations of the Comet =
Shoemaker-Levy 87 H1 (Note: Not Shoemaker-Levy 9) to try to determine the =
size of its nucleus. This comet is farther than 19 AU from the sun, and =
should show the bare nucleus. The observations were executed as =
scheduled, and no anomalies were noted.

1.3 Completed Three Sets of WF/PC-2 6183 (WF/PC-2 Cycle 5 Calibration: =
Decon)

The WF/PC-2 was used to make some internal flat, K-Spot, and dark =
calibration images. The purpose is to define decontamination procedures =
to be run during Cycle 5. The calibration observations were completed as =
scheduled, and no anomalies were reported.

1.4 Completed FOS/BL 5781 (Emission Line Variability in the Lensed =
Quasar Q0957+561: Carryover)

The Faint Object Spectrograph (Blue side) was used to make =
observations of the lensed quasar Q0957+561 (A and B) to study its =
emission line variability. From IUE data it was found that the flux =
ratio, A/B varies significantly on a time scale of two weeks. The =
observations were executed as scheduled, and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 3
Successful : 3

Scheduled Reacquisitions : 12
Successful : 12

2.2 FHST Updates:

Scheduled : 5
Successful : 5

2.3 Operations Notes:

There were no ODMs due to a NASCOM line outage during events at =
348/1537Z and 348/1618Z. There was a nine minute unrecoverable =
engineering data loss at 348/1638Z while in the coherent mode due to =
unknown NASCOM problems. TTRs were written dor each both occurrences.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

Nothing at this time.
