Daily Status Report as of 297/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed 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.

   1.2 Completed Two Sets of FOS/BL 6913 (FOS Cycle 6: Location of =
Spectra and Wavelength Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make a =
series of stability calibration measurements of the wavelength location =
and the location of the spectra.  All the observations were internals.  =
The observations were completed as planned, and no problems were =
reported.

   1.3 Completed WF/PC-2 6733 (Spatially Resolved Mapping of Titan's =
Atmosphere )

       The WF/PC-2 was used to make observations at several different =
wavelengths of the atmosphere on Saturn's largest moon Titan as part of a =
spatially resolved mapping program.  Methane gas and organic aerosols are =
the major contributor to the atmosphere's opacity.  The observations were =
completed as planned, and no anomalies were reported. 

   1.4 Completed FOS/BL 6624 (Time-Resolved Spectrophotmetry of the =
Smallest Mass Function Binaries)

       The Faint Object Spectrograph (Blue Side) was used to make time =
resolved, period mode, spectrographic observations of a low mass, x-ray, =
binary star system KZ Tri.  The observations covered an entire orbital per=
iod, but not one orbit.  An internal calibration image was also taken.  =
The observations were completed as planned, and no anomalies were noted. 

   1.5 Completed Two Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  =
The observations were completed as scheduled, and no problems were =
reported.

   1.6 Completed Two Sets of WF/PC-2 6802 (Cosmology With the Medium Deep =
Survey)

       The WF/PC-2 was used to make observations taken in parallel with =
the prime science observations as part of the Medium Deep Sky Survey.  =
The observations were executed as scheduled, and no problems were =
reported.

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

       The WF/PC-2 was used to make several internal calibrations =
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.

   1.8 Completed WF/PC-2 6364 (Snapshot Survey of Proto-Planetary Nebulae =
and AGB Stars)

       The WF/PC-2 was used to make some snapshot survey observations of =
protoplanetary nebular system IRAS17150 to study its circumstellar =
envelope.  The purpose is to discern the evolutionary sequence that =
produces axially-symmetric planetary nebulae.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.9 Completed FGS 6919 (Three Points of Light Calibration)

       The FGS were used to make a Three Points of Light calibration by =
making observations of standard star UPGREN6.  This calibration will be =
done at three different points in FGS#3 using three different filters =
(pupil, clear and neutral density).  This will be used to obtain a =
reference transfer function which will be used to deduce the presence of =
secondary stars in multiple star systems.  The observations were executed =
as scheduled, and no anomalies were noted.
