1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6565 (Imaging of Proto-Planetary Nebulae)

       The WF/PC-2 was used to make high resolution observations of the =
proto-planeatary nebula IRAS17150 which is known to show bipolar =
morphologies in ground-based observations.  The observations were =
executed as scheduled, and no anomalies were noted. 

   1.2 Completed WF/PC-2 6366 (The Early Onset of Asymmetric Outflow =
During the Planetary Nebula Formation)

       The WF/PC-2 was used to make observations of the planetary nebula =
QY Sge in order to study its asymmetric outflow during its formation.  =
The purpose of these exposures was to determine the characteristics of =
the mass loss that occurs as a star leaves the asymptotic giant branch.  =
The observations were completed as planned, and no problems were reported.=


   1.3 Completed Two Sets of WF/PC-2 6673 (Black Holes and Gas Disks in a =
Complete Sample of Radio-Loud UGC Ellipticals)

       The WF/PC-2 was used to make observations of radio-load, =
elliptical galaxies UGC05073 and UGC07455 in order to search for possible =
 black holes and gas disks.  Hydrogen-Alpha and broad band observations =
were taken to determine the luminosity profiles and stellar populations =
(on the tens of parsec scale), and detect nuclear regions or disks of gas =
and dust.  The observations were completed as planned, and no anomalies =
were reported. 

   1.4 Completed WF/PC-2 6740 (Hyper-Luminous IRAS Galaxies: Star =
Formation, AGN or LENSES?)

       The WF/PC-2 was used to make observations of the hyper-luminous =
IRAS galaxy FSC10026+4 in order determine if its luminous state is a =
result to its being a gravitational lens system or an active galactic =
nuclei (AGN) system.  This IRAS galaxy is known to emit an enormous =
amount of power (>10^13 LSUN) in the far infrared.  The observations were =
completed as planned, and no anomalies were reported. 

   1.5 Completed WF/PC-2 6583 (The Origin of the Alignment Effect: =
WF/PC-2 Imaging Polarimetry of High Redshift Radio Galaxies)

       The WF/PC-2 was used to make imaging polarimetry observations of =
the high redshifted galaxies 3C266 and 3C265.  These polarimetric =
observations are crucial to the understanding of the spectacular =
morphologies recently discovered in high redshift radio galaxies by HST, =
and to the investigation of morphological and evolutionary links between =
radio galaxies and quasars.  The observation were completed as scheduled, =
and no anomalies were reported. 

   1.6 Completed WF/PC-2 6837 (The Ultraviolet Properties of "Dwarf" =
Seyfert 1 Nuclei)

       The WF/PC-2 was used to make ultraviolet observations of the =
"dwarf", type-one, Seyfert galaxy NGC-2639.  This class of "dwarf" =
Seyfert populate the faint end of the local AGN luminosity function and =
hold important clues to the evolution of the entire AGN population.  The =
observations were completed as scheduled, and no problems were reported. 

   1.7 Completed WF/PC-2 6587 (Black Holes and Cores of Early-Type =
Galaxies)

       The WF/PC-2 was used to make observations of early-type galaxy =
NGC-4125 in order to study its nuclear core region and its possible black =
hole.  The campaign to find black holes in the centers of galaxies using =
HST has so far been highly successful.  The observations were completed =
as planned, and no problems were reported. 

   1.8 Completed STIS/CCD 7099 (CCD Flat-Field Stability and Cosmetic =
Defect Fraction)

       These observations were used to verify cosmetic defect fraction on =
the CCD using flat-field images, and to  investigate flat-field stability =
over short (minutes) and
long (days) time intervals.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.9 Completed Two Sets of WF/PC-2 6361 (High Resolution Imaging of =
X-Ray Selected AGNs)

       The WF/PC-2 was used to make high resolution  observations of the =
known low red shifted x-ray active galactic nuclei (AGN) MS1420.1+2 and =
MS0340.3+0.  These data will allow a study of the optical properties of =
an unbiased sample of AGN host galaxies.  The observations were completed =
as scheduled, and no problems were reported.

   1.10 Completed WF/PC-2 7016 (WF/PC-2 SM97 UV Monitor And Cool Down =
Procedure)

       This operation was used as a post-SM97 cooldown of the WF/PC-2 CCD =
to -88C with frequent monitoring of contamination via standard star =
GRW+70D582 observations in filter F170W.  An internal flat and a dark =
calibration image were also taken.  The observations were completed as =
planed, and no problems were reported

   1.11 Completed STIS/CCD 7063 (STIS SMOV CCD Contamination Monitor)

       The Space Telescope Imaging Spectrograph/CCD was used to measure =
the flux from the standard star G191B2B and to look for any gross changes =
over time that might indicate contamination.   A waveline contamination =
image was also taken.  The observations were executed as planned, and no =
anomalies were reported. 

   1.12 Completed WF/PC-2 6826 (The Galactic Wind in M-82: Structure and =
Excitation of the Optical Filaments)

       The WF/PC-2 was used to make narrow-band image  observations of =
galaxy NGC-3034 (aka, M-82) in order to study its structure and the =
excitation of its optical filaments, and the nature of emission lines of =
H-Alpha, [N II] 6583 A0, [O I] 6300 A0, and [O III] 5007 A0.  The =
observations were executed as scheduled, and no anomalies were reported. 

   1.13 Completed FGS 6879 (Parallax of TV-Col)

       The FGSs were used to make astrometric observations of the x-ray =
variable star TV-Col to obtain its precise parallax measurements.  The =
observations were executed as scheduled, and no anomalies were noted. 

   1.14 Completed WF/PC-2 6787 (Fine Structure in Ejection Nebulae Around =
Population I and II Wolf-Rayet Stars)

       The WF/PC-2 was used to study the fine structure of the ejection =
nebula around the Wolf-Rayet star PK050+03D1.  The unique high spatial =
resolution and wide field of WF/PC-2 camera was used to test =
quantitatively for the presence of supersonic, compressible turbulence in =
nebulae ejected by hot the W-R stars.  The observations were executed as =
planed, and no anomalies were reported. 

   1.15 Completed WF/PC-2 7019 (WF/PC-2 SMOV Flat Field Check)

       The WF/PC-2 was used to obtain a sequences of Earth streak and =
internal flats to check for changes at the 1% level.  The observations =
were completed as scheduled, and no problems were reported 

   1.16 Completed WF/PC-2 6737 (Imaging Reflection Nebulosity in Three =
Post-AGB Objects)

       The WF/PC-2 was used to make observations of the reflection nebula =
surrounding the post-AGB objects HD234478 and HD161796.  The physical =
mechanism of stellar mass loss on the AGB is one of the unsolved problems =
in stellar astrophysics.  The observations were completed as scheduled, =
and no anomalies were reported.
