HUBBLE SPACE TELESCOPE
DAILY REPORT #1092

PERIOD COVERED: 0700 EST
Daily Status Report as of 069/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5392 (Mapping Io's Surface and Volcanic Activity:
Cycle 4 Medium)

The WF/PC-2 was used to make images of the surface of Jupiter's moon
Io to study changes since the Voyager Mission and before the Galileo
Mission. The observations were made of longitude 315 degrees on the
moon's surface. Five observations were received and displayed. They
all were reported to look fine.


1.2 Completed Two Sets WF/PC-2 5090 (Large Area/Multicolor Survey: Cycle
4)

The WF/PC-2 was used to make deep exposure images of field #1416 as
part of a large area high galactic latitude multicolor sky survey to
learn more about the distribution of galaxies, their morphology,
distribution in magnitude and redshift, and evolution of galactic
luminosity function and colors. Eight observations were completed as
scheduled. Four images had recentering events, and two images showed
signs of a satellite trail. The other images were reported to be
okay.

1.3 Completed Two Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR Radio
Galaxies)

The WF/PC-2 was used to make snapshot images of radio galaxy 3C171.0
as part of a continuum survey and to study the galaxy's morphology.
Two images were executed in fine lock with no apparent problems. The
science data remains on the spacecraft, and will be analyzed later.

1.4 Completed Three Sets of WF/PC-2 5240 (SMOV-WF/PC-2 Flat Fields
Calibration)

The WF/PC-2 was used to make a visual internal flat image. The
observations were executed without apparent problems. The data
remains on the spacecraft.

1.5 Completed WF/PC-2 5206 (The Crab Nebula)

The WF/PC-2 was used to make a high spatial resolution observation
of the Crab Nebula (aka, M-1) to study the ionization structure of
the filaments within the nebula. This is to study the chemical
composition of the nova ejecta, photoionization processes, dust
formation, and interaction of thermal and relativistic plasmas. The
observation was reported to have encountered some several minute
long recentering events. Complete analysis is pending the science
tape recorder (STR) dump.

2.4 Operations Notes:

Another quiet operational day was experienced, as all SMOV functions
and HST subsystem activities were completed without incident.
