Daily Status Report as of 208/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOC/48 6746 (Dynamics of the Circumnuclear Disk of M87)

       The Faint Object Camera (f/48) was used to make long-slit =
spectrographic observations of the nucleus of the Ep class, elliptical =
galaxy M-87 which is located in Virgo.  This is to study the dynamics of =
its inner nuclear disk.  From these data the disk of ionized gas may be =
traced inward to as close a 5 parsecs from the nucleus and the rotation =
of the disk may be modeled.  The observations were executed as scheduled, =
and no anomalies were noted. 

   1.2 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 =
observation was also taken.  The observations were completed as planned, =
and no anomalies were reported.

   1.3 Completed WF/PC-2 6663 (Systematic Investigation of C/1995 01 =
(Hale-Bopp))

       The WF/PC-2 was used to make observations of the comet Hale-Bopp =
(aka, comet C/1995-01) as part of a systematic investigation of the =
comet.  The comet is being monitored over a wide range of heliocentric =
distances.  These data at different distances will provide unique =
information the sublimation behavior of the material in this comet.  The =
observations were completed as planned, and no problems were reported. 

   1.4 Completed GHRS/1/2 6415 (Thermal Pressures of the Local =
Interstellar Medium)

       The High Resolution Spectrograph (Sides One and Two) was used to =
make observations of the star HD196867 in order to study the thermal =
pressure of the interstellar medium which lies in the line of sight to =
that star.  The observations were completed as scheduled, and no =
anomalies were reported.

   1.5 Completed FOC/96 6349 (Snapshot search for High Redshift QSOs with =
Far-UV Flux)

       The Faint Object Camera (f/96) was used to make snapshot images of =
the quasi-stellar object Q2138-389.  This is to determine if this high =
redshifted object has a far ultraviolet flux.  The observations were =
executed as scheduled, and no anomalies were noted.
