HUBBLE SPACE TELESCOPE

DAILY REPORT #1686

PERIOD COVERED: 0000Z (UTC) 07/30/96 - 0000Z (UTC) 07/31/96

Daily Status Report as of 213/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of FOS/RD 6167 (FOS Cycle 5: Dark Monitoring)

The Faint Object Spectrograph (Red Side) was used to make several =
dark calibration images. All exposures were internals. All spectra was =
done in the image mode. The observations were completed as planned, and =
no problems were reported.

1.2 Completed Two Sets of WF/PC-2 6903 (WF/PC-2 Cycle 6 Calibration: =
Decontamination)

The WF/PC-2 was used to make several calibration bias =
observations, internal flats, K-Spot images and dark calibration images =
which are all part of a Cycle 6 decontamination procedure. No science =
was interleaved with the dark exposures. The observations were completed =
as scheduled, and no problems were reported.

1.3 Completed GHRS/1 6758 (Far UV airglow and Albedo Observations of =
Europa and Ganymede)

The High Resolution Spectrograph (Side One) was used to make far =
ultraviolet spectrographic observations of the airglow and albedo of =
Jupiter's moon Europa (at Western Elongation). The long term stability =
of the oxygen airglow emission and the magnitude of the hemisphere =
asymmetry will be determined. The observations were completed as =
planned, and no problems were reported.

1.4 Completed FOS/BL 6766 (Narrow Line Seyfert 1S and the Iron Enigma =
in Active Galaxies)

The FOS (Blue Side) was used to make observations of the 1S class =
narrow-lined Seyfert galaxy WPVS007 in order to study its iron enigma. =
These data should show correlations between its x-ray spectra, =
kinematics, and Fe II spectra. The observations were completed as =
planned and no problems were reported

1.5 Completed GHRS/1 6692 (The Abundance and Distribution of Deuterium =
on Saturn)

The High Resolution Spectrograph (Side One) was used to make =
observations of the limb of the planet Saturn and its moon Rhea in order =
to study the abundances and distribution o Deuterium in Saturn's upper =
atmosphere. The GHRS aperture was allowed to drift across Saturn's limb, =
mimicking an occultation. A wavelength calibration image was also taken. =
The observations were executed as scheduled, and no anomalies were =
noted.

1.6 Completed WF/PC-2 6902 (WF/PC-2 Cycle 6 Photometric Calibration =
Monitor UV/OPT STD)

The WF/PC-2 was used to make both ultraviolet and optical =
photometric observations of the standard star GRW+70D582 as part of a =
Cycle 6 calibration procedure. This observations was done immediately =
before and after decontamination procedures. The observations were =
completed as planned, and no problems were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 6
Successful : 6

Scheduled Reacquisitions : 9
Successful : 9

2.2 FHST Updates:

Scheduled : 12
Successful : 12

2.3 Operations Notes:

Ten minutes, 34 seconds of real-time, re-coverable data was lost =
when there was a problem with the WSGTU MA antenna. A TTR was written.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

Nothing at this time.
