HUBBLE SPACE TELESCOPE

DAILY REPORT #1806

PERIOD COVERED: 0000Z (UTC) 01/30/97 - 0000Z (UTC) 01/31/97

Daily Status Report as of 031/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of WF/PC-2 7202 (The WF/PC-2 B Band Parallel =
Survey: A Systematic and Synoptic Study of Galaxy Formation and Evolution =
- Short Orbit Case)

The WF/PC-2 was used to make observations as part of a B-Band =
Survey to make synoptic study of galaxy formation and evolution. These =
observations were taken in parallel with the prime science observations. =
They were completed as planned, and no anomalies were reported.

1.2 Completed WF/PC-2 6363 (The Environments and Host Galaxies of =
BL-Lac Objects)
363

The WF/PC-2 was used to make snapshot survey observations of =
BL-Lac object 1ES2326+17 in order to study its environment and its host =
galaxy. The goal is to investigate systematic trends in host galaxy =
type, unusual morphological features, nearby companion galaxies, etc. =
The observations were executed as scheduled, and no anomalies were noted.

1.3 Completed WF/PC-2 6584 (Interaction of Supernovae With =
Curcumstellar Material)

The WF/PC-2 was used to make observations of Supernova SN1979C. =
The objective is to study the interaction between the supernova and the =
remnant circumstellar material from the progenitor star, and how that =
interaction can sustain supernovae luminocity for long periods. The =
observations were completed as planned, and no problems were reported.

1.4 Completed Two Sets of WF/PC-2 6773 (The Bucher-Oemler Effect in =
Nearby Clusters of Galaxies)

The WF/PC-2 was used to make observations of several starburst and =
post-starburst regions in the nearby galaxies and in the coma of =
COMA-D99. These data will be studied to determine what triggers major =
episodes of star formation and what physically undermines the observed =
Butcher-Oemler effect in more distant galaxies. The observations were =
completed as planned, and no problems were reported.

1.5 Completed WF/PC-2 6419 (Testing Unified Models With a Complete =
Sample of Seyfert Galaxies)

The WF/PC-2 was used to make observations of the Seyfert galaxy =
NGC-4968 to help build a complete survey of the Seyfert class of =
galaxies. This will help test the current model for Seyfert class =
galaxies. This model proposes that all Seyferts have Seyfert-1 nucleus, =
which is surrounded by a torus of gas and dust. The observations were =
completed as planned and no anomalies were noted.
