Daily Status Report as of 207/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6348 (Blue Continuum Snapshots of 3CR Radio =
Galaxies)

       The WF/PC-2 was used to make some snapshot images of the blue =
continuum in radio galaxy 3C322.0.  Combined with existing data, these =
exposures will provide high spatial resolution information on the color =
distribution within galaxies, redding due to dust, spacial indices of the =
optical synchrotron jets, and colors of the active nuclei and tidal jets. =
 The observations were executed as planned with no reported anomalies.

   1.2 Completed FOS/RD 6091 (Ionization and Abundances of BALQSOs)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of BALQSO 1524+5147 in order to study its ionization and =
abundances.  This QSO is known to show broad absorption lines in its =
spectra.  The goal is to observe lines from several different ionization =
states of oxygen.  The observations were completed as planned, and no =
anomalies were reported.

   1.3 Completed GHRS/2 6615 (Fundamental Parameters of White Dwarfs in =
Close Binaries)

       The High Resolution Spectrograph (Side Two) was used to make =
extreme ultraviolet spectrographic observations of the close binary =
system EUVE-J1016 (a white dwarf/M-dwarf binary system) in order to =
obtain fundamental parameters of its white dwarf star.  As the older star =
ages through the asymptotic branch phase, the gaseous envelope which =
encompasses both stars dissipates and the white dwarf becomes visible.  A =
wavelength calibration image was also taken.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.4 Completed Two Sets of FOS/BL 6166 (FOS Cycle 5: Location of =
Spectra and Wavelength Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make =
wavelength calibration images to measure the stability of the FOS Blue =
Side wavelength scale and spectral locations.  A Taled calibration =
observations was also taken.  The observations were completed as planned, =
and no anomalies were reported.

   1.5 Completed WF/PC-2 6774 (Temporal Variability in Io's Surface and =
Plumes)

       The WF/PC-2 was used to make observations of Jupiter's moon Io at =
Longitude 340 degrees in order to study temporal variability in its plume =
and surface markings.  The longitude was chosen such that a known volcano =
will be present at Io's limb.  The proposal was executed as planned, and =
no anomalies were noted.
