PERIOD COVERED:  0000Z (UTC) 10/17/96 - 0000Z (UTC) 10/18/96

Daily Status Report as of 292/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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.

   1.2 Completed FOS/RD 6912 (FOS Cycle 6: Dark Monitoring)

       The Faint Object Spectrograph (Red Side) was used to make measureme=
nts of the internal background.  All exposures were internals, and the =
spectrographic observations were made in the image mode.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.3 Completed GHRS/1/2 6617 (The ISM Toward Nearby High Velocity =
Stars)

       The High Resolution Spectrograph (Both Sides One and Two ) was =
used to make spectrographic observations of the high velocity star =
HD201091 in order to study  the Inter Stellar Medium (ISM) in the =
direction toward this star.  This is to determine the accurate Deuterium =
to Hydrogen ratio in this local interstellar gas.  A wavelength =
calibration image was also taken.  The observations were executed as =
scheduled, and no anomalies were noted. 

   1.4 Completed FOS/RD 6408 (NGC-1569 as a Local Probe of Galactic =
Evolution at High Redshift)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the irregular galaxy NGC-1569.  These data =
will be used to study the star formation history and chemical evolution =
of this galaxy.  The interstellar medium in NGC-1569 is expelled and =
forms a large scale outflow due to the effects of the stellar winds and =
supernovae.  The observations were executed as scheduled, and no =
anomalies were noted. 

   1.5 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. 

   1.6 Completed Three Sets of 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.

   1.7 Completed WF/PC-2 6733 (Spatially Resolved Mapping of Titan's Atmos=
phere )

       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 atmospheres opacity.  The observations were =
completed as planned, and no anomalies were reported. 

   1.8 Completed WF/PC-2 6907 (WF/PC-2 Cycle 6 Calibration: Internal =
Flats)

       The WF/PC-2 was used to make internal flat filter sweep =
calibration images.  This is a series of exposures to test the linearity =
of the camera.  The observations were completed as planned and no =
problems were reported. 

   1.9 Completed WF/PC-2 6347 (A Search for Jets in Planetary Nebulae)

       The WF/PC-2 was used to make observations of the planetary nebulae =
(class PNe) PK051+09D1 in order to search for the presence of possible =
narrow jets.  The current model for PNe formation indicates that jets are =
an unexpected phenomena.  Yet there is a growing body of circumstantial =
evidence that suggests narrow jets are common feature in PNe.  The =
observations were completed as scheduled, and no anomalies were noted.

   1.10 Completed Two Sets of FGS 6923 (Red TF Calibration)

       The FGSs were used to make astrometric observations of standard =
star HD59149 as part of a red reference transfer function (TF) =
calibration.  Observations were made through the pupil, clear, and =
neutral density filters.  The observations were completed as planed, and =
no anomalies were noted. 

   1.11 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.
