HUBBLE SPACE TELESCOPE

DAILY REPORT #1524

PERIOD COVERED: 0000Z (UTC) 11/27/95 - 0000Z (UTC) 11/28/95

Daily Status Report as of 332/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5982 (Imaging of a Complete Sample of the Nearest =
Infrared Quasars)

The WF/PC-2 was used to make two color observations of the nearby =
infrared quasar (IR QSO) MRK463. It is believed that this IR QSO resulted =
from the merger of two gas-rich galaxies. The observations were executed =
as planned, and no anomalies were reported.

1.2 Completed GHRS/2 5315 (Stellar Wind Instabilities)

The High Resolution Spectrograph (Side Two) was used to obtain high =
signal/noise spectra of the N V, Si IV, and C IV lines of the O-star =
HD210839. The objective is to monitor the stellar wind on short time =
scales at sufficiently high signal to distinguish between low-velocity, =
mechanically-driven instabilities and intrinsic, radiatively-driven =
instabilities, and to define the interaction between the two regimes. The =
observations were executed as scheduled, and no problems were reported.

1.3 Completed Four 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.

1.4 Completed WF/PC-2 6119 (Snapshot Survey for Companions of Planetary =
Nebula Nuclei)

The WF/PC-2 was used to make snapshot survey observations of =
planetary nebula A34 to study its nucleus and to look for possible =
companions. The observations were executed as scheduled, and no anomalies =
were noted.

1.5 Completed WF/PC-2 5836 (Saturn Ring Plane Crossing Observations in =
August and November 1995)

The WF/PC-2 was used to make observations of the rings of the =
planet Saturn during the ring plan crossing in order to determine their =
thickness and distortion. The moons Pan and Atlas will also be observed. =
The observations were completed as planned, and no problems were reported.

1.6 Completed Three Sets of WF/PC-2 5957 (Snapshot of 3CR Radio Galaxies)

The WF/PC-2 was used to make observations of radio galaxies =
3C338.0, 3C213.1, and 3C277.3 to study the morphology of these radio =
galaxies. The observations were executed as scheduled, and no anomalies =
were noted.

1.7 Completed WF/PC-2 5999 (The Nuclear Structure of S0 Galaxies: A PC =
Imaging Survey)

The WF/PC-2 was used to make observations of S0 class galaxy =
NGC-3414 in order to study its nuclear structure. This is a part of a =
large survey of S0, E/S0, and S0/a class galaxies. The targets will cover =
a wide range in luminosity and environment. The observations were =
completed as planned, and no anomalies were noted.

1.8 Completed GHRS/1 5412 (The Boundary Layer White Dwarf Connection: CV =
White Dwarf Rotation)

The High Resolution Spectrograph (Side One) was used to make =
observations of the white dwarf nova star U-Gem after a period of =
outbursts. The observations were completed as scheduled, and no anomalies =
were reported.

1.9 Completed Two Sets of FOS/RD 6236 (FOS Cycle 5: Location of Spectra =
and Wavelength Calibration: Red Side Detector)

The Faint Object Spectrograph (Red Side) was used to make =
calibration observations in order to determine the location of the spectra =
and to perform a wavelength calibration. All observations were internal. =
A Taled calibration was also completed. The observations were completed =
as planned, and no anomalies were reported.

1.10 Completed FOS/RD 5951 (Ly Alpha Forest, Abundances, and Cloud =
Properties)

The Faint Object Spectrograph (Red Side) was used to obtain spectra =
along the line-of-sight (LOS) to the two components of QSO HE 1104-1825. =
The prime intent is to measure the number density and lateral dimensions =
of the clouds that produce the Lyman Alpha forest. A secondary aim is to =
measure the CNO abundances in these clouds to determine the ionization =
condition. The observations were completed as scheduled, and no anomalies =
were noted.

1.11 Completed WF/PC-2 5971 (HST Medium Deep Survey)

The WF/PC-2 was used to make a long exposure, medium deep sky =
survey observations at latitudes larger than 10 degrees taken in parallel =
with the prime science observations. The observations were executed as =
scheduled, and no anomalies were noted.
