Daily Status Report as of 096/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2/HRS-1/FOS/BL 6736 (A Comprehensive Study of H =
Lyman Alpha Line Profile and Water)

       The WF/PC-2, High Resolution Spectrograph (Side One), and the =
Faint Object Spectrograph (Red Side) all were used to make observations =
of the comet Hyakutake in order to make a comprehensive study of hydrogen =
Lyman Alpha and water in the comet.  The results should improve the =
understanding of how water is produced and destroyed in comets.  The =
observations were completed as scheduled, and no anomalies were noted.

   1.2 Completed FGS 6274 (Linking the HIPPARCOS to the Extragalactic =
Referance Frame)

       The FGS#3 was used to make astrometeric observations of =
extra-galactic objects 1435+638IN, 320-REF, INCA221-98, and several other =
reference stars in order to help link the HIPPARCOS satellite reference =
frame to that of the HST.  The observations were completed as planned, =
and no anomalies were reported.

   1.3 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.

   1.4 Completed Two Sets of WF/PC-2 6363 (The Environments and Host =
Galaxies of BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations of =
BL-Lac objects PKS2131-02 and PG1246+586 in order to study their =
environment and their host galaxies.  The goal is to investigate =
systematic trends in host galaxy type, unusual morphological features, =
nearby companion galaxies, etc.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.5 Completed FOS/RD 6044 (Carbon in the ISM of Spirals)

       The Faint Object Spectrograph (Red Side) was used to obtain =
ultraviolet and optical spectra of the H II regions in spiral galaxy =
NGC-5455.  The intent is to derive the carbon abundances and =
carbon/oxygen ratios at several positions in this galaxy.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.6 Completed WF/PC-2 5982 (Imaging of a Complete Sample of the =
Nearest Infrared Quasars)

       The WF/PC-2 was used to make two color observations of the nearby =
infrared quasar (IR QSO) IRAS17044.  It is believed that this IR QSO =
resulted from the merger of two gas-rich galaxies.  The observations were =
executed as planned, and no anomalies were reported.

   1.7 Completed WF/PC-2 6353 (A Snapshot Emission Line Imaging Survey of =
Very Low Excitation Planetary Nebulas)

       The WF/PC-2 was used to make snapshot observations as part to an =
emission line survey of the very low excitation planetary nebula =
PK320-09D1 (Class PNe).  This target was selected based on the O III/H =
alpha line flux ratio.  The observations were executed as scheduled, and =
no anomalies were noted.

   1.8 Completed WF/PC-2 6849 (A Photometric Search For Planets of Nearby =
Stars: GTO Prop. Continuation)

       The WF/PC-2 was used to make a photometric search of the nearby =
star L145-141 to look for possible planets.  Images through both the wide =
and narrow-band filters were obtained.  The observations were completed =
as planned, and no anomalies were reported.

   1.9 Completed FOC/48 6200 (F/48 Geometric Correction and Plate Scale: =
Cycle 5)

       The Faint Object Camera (f/48) was used to make observations of =
test cluster NGC-104 (aka, 47 Tuc) in order to make geometric corrections =
to the plate scale calibrations.  This cluster has been used in the past =
to calibrate the geometric distortion and plate scale in the F/96 relay.  =
The observations were completed as planned, and no problems were =
reported.

   1.10 Completed WF/P-2 6254 (GTO Pure Parallel Program - Cycle 5)

       The WF/PC-2 was use to make random long exposures of high galactic =
fields taken in parallel with the prime science observations to obtain a =
random sample of galaxies.  The observations were executed as scheduled, =
and no anomalies were noted.
