HUBBLE SPACE TELESCOPE

DAILY REPORT #1745

PERIOD COVERED: 0000Z (UTC) 10/23/96 - 0000Z (UTC) 10/24/96

Daily Status Report as of 298/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Three Sets of FGS 6919 (3 Points of Light Calibration)

The FGSs were used to make a Three Points of Light calibration by =
making observations of standard star UPGREN69. This calibration will be =
done at three different points in FGS#3 using three different filters =
(pupil, clear and neutral density). This will be used to obtain a =
reference transfer function which will be used to deduce the presence of =
secondary stars in multiple star systems. The observations were executed =
as scheduled, and no anomalies were noted.

1.2 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.

1.3 Completed FOS/RD 6203 (FOS Cycle 5: Photometric Calibration)

The Faint Object Spectrograph (Red Side) was used to make =
observations of standard star BD+26D4211 in order to perform an absolute =
sensitivity photometric calibration of the instrument. Following a =
successful guide star acquisition at 297/061550Z, there was an FOS status =
buffer message indicating that the on-board peakup real-time command =
sequence timed out while waiting for the HST to become stable after the =
slew to the dwell point. As a result the take data flag did not come up. =
HSTAR 5152 was written. Otherwise, the observations executed as =
scheduled, and no further anomalies were noted.

1.4 Completed WF/PC-2 7203 (Cosmology with the Medium Deep Survey - =
Short Orbit Cases)

The WF/PC-2 was used to take short (about 20-minute) exposures, to =
be taken in parallel with the prime science observations, using the I =
filter. These exposures are part of the medium-deep survey, which =
emphasizes exposures that will be useful in obtaining cosmological =
parameters. The observations were completed as planned, and no problems =
were reported.

1.5 Completed GHRS/1 6454 (UV Spectroscopy of a DAO Dwarf Showing =
Signatures of an Extremely Hot Wind)

The High Resolution Spectrograph (Side One) was used to make =
ultraviolet spectrographic observations of the DAO peculiar white dwarf =
star HS2115+114 which is one of the small group of stars in the =
Hamburg-Schmidt Survey. The spectra of this class of stars exhibit =
shallow metal absorbing lines from ultra-high excited ionization stages. =
The observations were executed as scheduled, and no anomalies were noted. =


1.6 Completed Two Sets of WF/PC-2 6253 (Pure Parallel Archive Program)

The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations. The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0. =
The observations were completed as planned, and no problems were =
reported.

1.7 Completed FOS/BL 6682 (Geometry and Generalizability of the =
Reflected Light Model for Seyfert Galaxies)

The Faint Object Spectrograph (Blue Side) was used to make =
spectropolarimetry observations of the Seyfert (class two) galaxy MARK78 =
in order to study its geometry and the generalizablity of its reflected =
light model. The goal is to determine if the polarization components of =
all Seyfert class two galaxies have Seyfert class one characteristics. =
The observations were completed as scheduled, and no problems were =
reported.
