HUBBLE SPACE TELESCOPE
DAILY REPORT #892

PERIOD COVERED: 0800 EST
Daily Status Report as of 141/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed HSP/UV1 4810 (Constraints on Continuum Models of Active
Nuclei: Fast Ultraviolet)

The High Speed Photometer was used to make five observations of the
of the Seyfert galaxy NGC-6814 and its active nuclei looking for rapid
variations in its ultraviolet flux levels. The first two
observations were received and displayed , and had low counts. The
third observations was reported to be okay. The last two
observations were reported to have had a recentering events which
occurred during the observations.

1.2 Completed WFC 4713 (WF/PC Cycle 2 Calibration: WFC Internal; Delta
Flats)

The Wide Field Camera was to make two internal flat observations.
These images will be used for the restoration of Earth flat images,
which were altered due to changes in quantum efficiency which
occurred after WFPC decontamination operations. The first internal
flat image was reported to be saturated, and the second was normal.

1.3 Completed HSP/POL 4888 (Remnant Stars in Supernova Remnants - AUG -
Cycle 3 High)

The High Speed Photometer was used to make observations of the star
SS433 (Visual Magnitude = 14.0) which is located in a supernova
remnant. The target star has emission lines that vary in velocity by
relativistic amounts in a 162 day cycle. The observations were
received and displayed in real time. The GO was present for the
observations. No anomalies were reported. Much of the data still
remains on the science tape recorder, and will be analyzed later.

1.4 Completed GHRS/2 3614 (Boron as a Probe of Stellar Structures and
Mass Loss)

The High Resolution Spectrograph was used to try and make
observations of G class star HD2151 to measure its abundance in
Boron. The baseline guide star acquisition failed in FGS #3 with a
search radius exceeded. The scientific observations were lost. (See
Note 2.1) .

1.5 Completed GHRS/2 1206 (Sulfur Near IO Cycle 2)

The High Resolution Spectrograph was used to make observations of
the spectrum of Jupiter's moon Io both inside and outside of the
plasma torus. This is to determine the mechanism which feeds sulfur
and oxygen into the torus. The observations were monitored by the
OSS, and the data quality was assessed. No problems were reported.

1.6 Completed FOS/BL 4054 (Probing the Nuclear Regions of Seyfert Galaxy
NGC-5548)

The Faint Object Spectrograph was used to make ultraviolet
observations of the nuclear regions of Seyfert galaxy NGC-5548 to
look for time dependent fluctuations in its continuum, and emissions
in Carbon IV and Helium II. The observations were executed as
scheduled, and no problems were reported.

2.0 FLIGHT OPERATIONS SUMMARY:

2.1 Guide Star Acquisitions:

Scheduled Acquisitions : 5
Successful : 4

Prime okay, secondary bad, search radius
exceeded 141/0229Z, subsequent reacquisition
effected. ARU/PRT did not help.

Scheduled Reacquisitions : 8
Successful : 7

141/0404Z, see above note.

Losses of Lock : 0

2.2 FHST Updates:

Scheduled : 8
Successful : 8

2.3 Significant HSTARs: None

2.4 Operations Note: None

A partial eclipse of the Sun occurred today, Friday May 21, 1993
(141/1313-1327Z). The maximum coverage of the Sun was 10.7%. Normal
operational procedures were used during the eclipse. The status of
the Battery Rate of Charge, as well as the Course Sun Sensors were
monitored during the eclipse. No problems were encountered.
