HUBBLE SPACE TELESCOPE

DAILY REPORT #1696

PERIOD COVERED: 0000Z (UTC) 08/13/96 - 0000Z (UTC) 08/14/96

Daily Status Report as of 227/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Competed Two sets of FOS/RD 6552 (Spectrophotometry of Inner =
Jovian Satellites)

The Faint Object Spectrograph was used to make spectrographic =
observations of Jupiter's inner moons Alalthea and Metis during their =
eastern elongation. Many things can be determined from the analysis of =
these spectra. A guide star loss-of-lock was encountered with FGS #1 with =
a torque star selector compensation error type B at 226/0514Z. During the =
FOS observation 14 a binary acquisition guide star loss-of-lock occurred =
taking the TDF down until the occultation at 0556Z. The NSSC-1 had a =
status buffer message at 226/0524Z due to no TDF at the start of the FOS =
observations #15. The Shutter did not open and the observation was lost. =
The FOS observation #16 was also conducted with the shutter closed. =
During the second set of observations a FOS Normal Mode 2 Target =
Acquisition failure was received at 226/1941Z. STB error message #3202 =
was received. No other problems were reported.

1.2 Completed FGS 6882 (Companion to GL623)

The FGSs were used to make POS and TRANS mode astrometric =
observations of star GL623 (aka, Gleise 623) looking for possible =
companions. Five other reference stars were also used. From these data =
the precise parallax, barycentic orbits, and accurate masses of the star =
and its companion will be determined. The observations were completed as =
schedule, and no anomalies were reported.

1.3 Completed Two sets of WF/PC-2 6650 (Atmospheric Dynamics and Cloud =
Structure on Neptune)

The WF/PC-2 was used to make multi-spectral observations of the =
planet Neptune in order to study its atmospheric dynamics and cloud =
structure. The images will be converted into maps of the cloud top =
surface. A status buffer message EXEC #410 was received at 226/1159 =
indicating the STR was declared ready because either the start STR =
request was rejected or the STR never became ready. The STR was started =
with SD flow instead of the start STR function of the PIT write command. =
Observation #27 may have been impacted or lost. (See HSTARs 5687, 5688 =
and 5689). No other anomalies were noted.
