HUBBLE SPACE TELESCOPE
DAILY REPORT #1011

PERIOD COVERED: 0800 EST
Daily Status Report as of 313/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed HSP/POL 3250 (Gravitational Lenses Part 1 - Cycle 2 High)

The High Speed Photometer was used to make ultraviolet photometric
observations of quasar QSO0957+56 which is an expected gravitational
lenes system. It is hoped to find a characteristic signature in
variability in the time scale of the order of weeks. The
observations were monitored, were possible. Most of the observations
were received in real-time and displayed. The data were reported to
be normal. The onboard target acquisition was successful. The
remainder of the data were received from the science tape recorder,
and they were reported to look okay.

1.2 Completed FGS 5068 (Linking the HIPPARCOS to the Extragalactic
Reference Frame part 6 of 6)

The Fine Guidance Sensor #3 was used to make two sets of
astrometric observations of object NEWEGOD-54 and reference e object
220-REF. This object lies near the apparent position of
extragalactic objects. This object will also be observed with the
HIPPARCOS satellite. The intent is to tie the HIPPARCOS system
reference frame to the extragalactic reference frame. The
observations were executed as scheduled. The observation occurred
during LOS and could not be monitored in real-time. The observation
of the reference object 220-REF was monitored in real-time and was
reported to look okay.

1.3 Completed FGS 4893 (Orbital Motions of Close Binary Stars - Cycle 3
High)

Fine Guidance Sensor #3 was used to make astrometric observations of
the binary star system HD181391 to obtain its orbital elements.
These observations are important since most of the estimates of
stellar mass are made by observing elements of these systems. The
continuous scans were monitored and no problems were seen in the
telemetry.

1.4 Completed GHRS/2 5041 (GHRS Sensitivity Monitor - Cycle 3)

The High Resolution Spectrograph was used to make ultraviolet
observations of standard star BD28D4211 to monitor the sensitivity
of the HRS, which is expected to change slowly with time. The
onboard target acquisition was successful. Both sets of observations
were received and displayed in the OSS. The target was well
centered. The astrometric observations were reported to look okay.

1.5 Completed GHRS/2 5024 (GHRS Telescope Breathing Monitor - Cycle 3)

The High Resolution Spectrograph was used to make observations of
the standard star HD184499 to look for variations in the flux
through the Small Science Aperture (SSA) and shifts in position
during the course of several orbits, which may be caused by
"breathing" in the secondary mirror. The observations were monitored
in the OSS, and the data quality was assessed. No anomalies were
noted.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 7
Successful : 6

There was a Guide Star Acquisition failure at
313/0445Z during a ZOE. A search limit was
exceeded for FGS #1. An ARU/PRT was performed
and the subsequent reacquisition was
successful.

Scheduled Reacquisitions : 10
Successful : 10

2.2 FHST Updates:

Scheduled : 9
Successful : 9

2.3 Significant HSTARs: None

2.4 Operations Note:

Simulation JIS #6 (EVA 4 and 5, plus Deploy) was initiated
yesterday morning, Monday, Nov. 8, 1993 at 8 AM and is scheduled to
last for 59 hours.
