Daily Status Report as of 241/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of GHRS/2 6172 (CRIMP2: Cycle 5 =
Condensed-Regimen Integrated Monitoring Program)

       The High Resolution Spectrograph (Side Two) was used  to obtain =
darks, internal flats (in photoscan mode), wavelength calibrations and =
observations of standard star BD+28D4211.  This includes detector =
calibration, sensitivity monitoring, and wavelength monitoring.  The =
observations were executed as scheduled, and no anomalies were noted. 

   1.2 Completed WF/PC-2 6905 (WF/PC-2 Cycle 6 Calibration: Internal =
Monitor)

       The WF/PC-2 was used to make several internal calibration =
observations including biases and internal flats as part of a Cycle 6 =
calibrations procedure.  A variety of internal exposures are run weekly =
to verify and monitor the health of the camera.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.3 Completed FOS/RD 6654 (Ultraviolet Spectroscopy of Hot DB White =
Dwarfs)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the hot, helium-atmosphere, DB White Dwarf class star =
WD1654+160.  The ultraviolet spectra will be used to determine the =
effective temperatures of this star, which shows discrepancies when =
calculated from the optical spectra due to traces of photospheric =
hydrogen which is not visible at optical wavelengths.  The observations =
were executed as scheduled, and no anomalies were noted. 

   1.4 Completed WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: Earth Flats)

       The WF/PC-2 was used to make observations of the bright earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.5 Completed Two Sets of WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were =
reported.

   1.6 Completed WF/PC-2 6906 (WF/PC-2 Cycle 6 Calibration: Internal =
Monitor-Visual Flats)

       The WF/PC-2 was used to make internal calibration visual flat =
images as part of the Cycle 6 internal monitoring of the instrument's =
operations.  This proposal defines the standard series of internal flat =
fields, which will be executed twice per month.  The observations were =
completed as planned, and no anomalies were reported.

   1.7 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 Q1422+231.  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.

   1.8 Completed GHRS/2/FOS/RD 6025 (Consequences of the Shoemaker-Levy =
Impact With Jupiter)

       The Faint Object Spectrograph (Red Side) and the High Resolution =
Spectrograph  (Side Two) were both used to make spectrographic =
observations of Jupiter's moon Calisto in order to study the possible =
consequences from the impact of the comet Shoemaker-Levy on Jupiter.  =
This is to study the atmosphere following the impact to measure the =
chemical abundances as a function of time.  The observations were =
completed as scheduled, and no problems were reported.

   1.9 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 3C36.0.  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 scheduled, and no anomalies were =
noted.

   1.10 Completed WF/PC-2 6749 (A Study of the Gaseous Halo of the =
Andromeda Galaxy)

       The WF/PC-2 was used to make absorption line spectrographic =
observations of object QSO 0035+4112 which is located behind the  =
Andromeda Galaxy (aka, M-31) in order to study the galaxy's gaseous halo. =
 The QSO's light passes through the galaxy.  The distribution, =
ionization, and kinematics of the gas will be investigated.  The =
observations were completed as planned and no anomalies were reported.

   1.11 Completed GHRS/1/2 6418 (Small-Scale ISM Structure: The =
Remarkable Sightline Toward MU Cru.)

       The High Resolution Spectrograph (Sides One and Two) was used =
(echelle mode) to make spectrographic observations of the binary star =
Mu-Cru (aka, HD112091).  These observations were made to study the small =
scale structure of the inter-stellar medium which lies in the =
line-of-sight to this star.  These observations will provide information =
on the small scale variations that appear to be present in the =
interstellar medium.  The observations were completed as planned, and no =
problems were reported.
