HUBBLE SPACE TELESCOPE

DAILY REPORT #1693

PERIOD COVERED: 0000Z (UTC) 08/08/96 - 0000Z (UTC) 08/09/96

Daily Status Report as of 222/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 6774 (Temporal Variability in Io's Surface and =
Plumes)

The WF/PC-2 was used to make observations of Jupiter's moon Io at =
longitude 215 degrees in order to study temporal variability in its plums =
and surface markings. The longitude was chosen such that a known volcano =
will be present at Io's limb. The observations were executed as =
scheduled, and no anomalies were noted.

1.2 Completed FOC/96 6161 (FOC/96 Cycle 5 Aperture Location Monitor)

The Faint Object Camera was used to make astrometric standard =
field observations of NGC-188-54 to monitor the location of the camera's =
f/96 apertures with respect to the V2-V3 coordinate frame. A dark =
calibration image was also taken. As initially mentioned in yesterday's =
report, the guide star acquisition for this proposal defaulted to fine =
lock guidance on FGS 3 only, possibly affecting four of the observations. =
HSTAR 5674 was written. Otherwise, the observations were completed as =
scheduled, and no further problems were reported.

1.3 Completed WF/PC-2 6780 (Spectroscopy and Imaging of a New Globular =
cluster Planetary Nebula)

The WF/PC-2 was used to make observations of the oxygen abundances =
in the planetary nebula NGC-6441-PN which is located in the large =
globular cluster NGC6441. The planetary nebula appears to be severely =
depleted in oxygen. The observations were completed as scheduled, and no =
problems were reported.

1.4 Completed Two Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

The WF/PC-2 was used to make internal dark calibration images. =
The observations were completed as scheduled, and no problems were =
reported.

1.5 Completed FOS/BL 6202 (Cycle 5 FOS Spectral Flat field =
Calibration)

The Faint Object Spectrograph (Blue Side) was used to make observat=
ions of the white, relatively featureless, white dwarf star WD0501+527 in =
order to make flat field calibration images. The observations were made =
through the 1.0 aperture, with all usable detector/disperser =
combinations. The observations were executed as schedule, and no =
anomalies were noted.

1.6 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS =
Galaxy Sample-Part 1 High)

The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous IRAS galaxy IR2249-18. These data will be searched for =
multiple cores, which imply a merger has occurred, and for starburst =
regions. The observations were executed as scheduled, and no anomalies =
were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 4

2.3 Operations Notes:

3.0 SIGNIFICANT FORTHCOMING EVENTS:

The RMGA Calibration Test will be performed today from =
approximately 1300Z until approximately 2000Z.
