Daily Status Report as of 263/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/1 6414 (Doppler Mapping of Chromospheric and =
Transition Region UV Emission Lines)

       The High Resolution Spectrograph (Side One) was used to make =
ultraviolet Spectrographic observations of the variable star BW-Drako in =
order to do doppler mapping of its chormospheric and transitional =
emission line region.  The observations were executed as scheduled, and =
no anomalies were noted. 

   1.2 Completed WF/PC-2 6903 (WF/PC-2 Cycle 6 Calibration: =
Decontamination)

       The WF/PC-2 was used to make several calibration bias =
observations, internal flats, K-Spot images and dark calibration images =
which are all part of a Cycle 6 decontamination procedure.  No science =
was interleaved with the dark exposures.  The observations were completed =
as scheduled, and no problems were reported.

   1.3 Completed FOS/RD 6914 (FOS Cycle 6: Location of Spectra and =
Wavelength Calibration - Red Side)

       The Faint Object Spectrograph (Red Side) was used to make both a =
TALED and a wavelength calibration image.  All observations were made =
using internal light sources.  This proposal will be executed a total of =
12 time during cycle 6 (i.e., once per month).  The observations were =
executed as scheduled, and no anomalies were noted.

   1.4 Completed FOS/BL 6741 (Synoptic Monitoring of Seasonal Phenomena =
on Mars)

       The Faint Object Spectrograph (Blue Side) was used in the rapid =
mode to make spectrographic observations of the surface and =
meteorological changes on the planet Mars in order to do synoptic =
monitoring of its seasonal phenomena.  Special attention will be given to =
the Ares Valley region, which is intended as a landing site for the Mars =
Pathfinder mission.  The observations were completed as planned, and no =
problems were reported.

   1.5 Completed GHRS/2 6078 (The Wind Momentum-Luminosity Relationship =
for SMC A and B Supergiants.)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the O/B class stars AV315 and AV136 which =
are located in the Small Magellanic Cloud in order to measure the wind =
momentum/luminosity relationship in these low metallicity stars.  This =
relationship is used to determine the distance to galaxies.  The =
observations were completed as planned and no problems were reported.
