HUBBLE SPACE TELESCOPE

DAILY REPORT #1488

PERIOD COVERED: 0000Z (UTC) 10/02/95 - 0000Z (UTC) 10/03/95

Daily Status Report as of 276/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 6114 (White Dwarf Distance and Precision Age for the
Globular Cluster 47 Tuc)

The WF/PC-2 was used to make observations of white dwarf stars
WD0002+729 and WD0644+375 which are located in the globular cluster 47 Tuc in
order to study the clusters age and distance. This set of observations will
be used to determine the distance to 47 Tuc, hopefully to an accuracy of
better than 10%. The observations were executed as scheduled, and no
anomalies were noted.

1.2 Completed WF/PC-2 5913 (Low Mass Binaries and the Luminosity Function.
)

The WF/PC-2 was used to make observations of the low mass binary star
system SPG002 (a late-type M class dwarf) to study the local stellar
luminosity function. The observations were executed as scheduled, and no
anomalies were noted.

1.3 Completed WF/PC-2 5939 (Evolution in the Isotropic Properties of BL
Lac Objects)

The WF/PC-2 was used to make observations of the BL Lac object
QSO1832+56 in order to study its evolution and isotropic properties. The
observations were completed as planned, and no problems were reported.

1.4 Completed WF/PC-2 5957 (Snapshot of 3CR Radio Galaxies)

The WF/PC-2 was used to make observations of radio galaxy FR533N33 to
study the morphology of the radio galaxy. The observations were executed as
scheduled, and no anomalies were noted.

1.5 Completed FOS/BL 6038 (Winds of Massive Stars in Nearby Galaxies, the
WR Stars)

The Faint Object Spectrograph (Blue side) was used to make spectrographic
observations of the massive Wolf-Rayette star M-33-OB10-3 which is located in
the M-33 Galaxy in order to study its stellar winds. The observations were
completed as planned, and no problems were reported.

1.6 Completed WF/PC-2 5907 (Colour Magnitude Diagrams of two
Super-Metal-Rich Globular Clusters)

The WF/PC-2 was used to make observations of the super-metal-rich
globular cluster NGC-224-G1. The high resolution of the PC will allow
individual stars to be distinguished, from which the investigator can build a
colour magnitude diagram of this unusual cluster. The observations were
completed as scheduled, and no problems were reported.

1.7 Completed GHRS/1 6088 (Ultraviolet Tomography of the Chromosphere of
the K2 Dwarf in V471 Tau)

The High Resolution Spectrograph (Side One) was used to make Rapid
Mode ultraviolet tomographic observations of a K2 class binary dwarf star and
its eclipsing binary white dwarf companion which are located in the cluster
V471-Tau in order to study its chromosphere. The observations were completed
as planned, and no anomalies were reported.

1.8 Completed GHRS/1 6070 (Interstellar Tin: Probing Galactic S-Process
Element Enrichment)

The High Resolution Spectrograph (Side One) was used to make Echelle A
observations of star HD57061 in order to probe for interstellar tin and to
study the galactic S-process neutron capture of element enrichment. The
observations were completed as planned, and no problems were reported.
