1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6475 (High Resolution Imaging of Unstable =
Massive Stars at the Top of the H-R Diagram)

       The WF/PC-2 was used to make high resolution, multi-color =
observations of unstable massive star IRC+10420 which is known to lie at =
the top of the H-R diagram.  This star is a cool hypergiant and a OH/IR =
class star with visible nebulosity.  The observations were executed as =
schedule, and no anomalies were noted.

   1.2 Completed WF/PC-2 6102 (Chemical Evolution and History of Star =
Formation in the Large Magallanic Cloud)

       The WF/PC-2 was used to make observations of the "Bar" region =
(ie., NGC-2682) in the Large Magellanic Cloud to study the chemical =
evolution and the history of star formation in that region.  The goal is =
to observe individual field stars near the main sequence turnoff in order =
to study the large scale processes that control star formation and =
nucleosynthesis in galaxies.  The observations were executed as planned, =
and no anomalies were reported.

   1.3 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images. =
 These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.4 Completed WF/PC-2 6646 (WF/PC-2 Imaging Dwarf Spirals)

       The WF/PC-2 was used to make ultraviolet and blue observations of =
the dwarf spiral galaxy D774-1.  It is know to have low surface =
brightness with very blue mean color but no evidence of recent or past =
star formation.  The observations were completed as planned, and no =
problems were reported.

   1.5 Completed WF/PC-2 5903 (The Origin and Nature of UV Bright stars =
in Globular Clusters.)

       The WF/PC-2 was used to make blue, violet, and ultraviolet =
observations of the globular cluster NGC-6093 in order to study its =
origin and nature.  The objectives are to study the horizontal branch =
mass distribution in this cluster, and to search for blue straggler stars =
in the core of the cluster.  The observations were completed as =
scheduled, and no problems were noted.

   1.6 Completed Two Sets of WF/PC-2 6346 (Snapshot Survey of the =
Ultraluminous IRAS Galaxy Sample-Part 1 High)

       The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous QDOTULIR12 and IR02364-47.  These data will be searched for =
multiple cores, which imply a merger has occurred, and for starburst =
regions.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.7 Completed FOC/96 6057 (Ultra--High Resolution Studies of AGNs II: =
3C279 Proper Motion)

       The Faint Object Camera (f/96) was used to make ultra-high =
resolution of active galactic nuclei in radio galaxy 3C279 in order to =
study the small scale morphology of the AGN.  The data will be searched =
for evidence of superluminal motion, which is known radio observations, =
and for time variable phenomena.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.8 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.

   1.9 Completed WF/PC-2 5913 (Low-Mass Binaries and Luminosity Fuction)

       The WF/PC-2 was used to make observations of a low-mass binary =
system in NGC-6853 (Late Type Class M dwarf stars).  The intent is to =
determine why the local stellar luminosity function is flat below =
Mv=3D12, while that found from more distant stars falls by an order of =
magnitude by Mv=3D14.  The observations were executed as scheduled, and =
no anomalies were noted.

   1.10 Completed FGS 6268 (The Parallax of NGC-6853)

       The FGSs were used to make astrometric observations in order =
measure the parallax to NGC-6853, one of the nearest planetary neabulae.  =
The observations were executed as planned, and no problems were reported.

   1.11 Completed Two Sets of WF/PC-2 5990 (Globular Clusters in the =
Fornax Galaxies)

       The WF/PC-2 was used to search for globular clusters in FIELD-0338 =
and galaxy NGC-1316 which is a member of the Fornax Galactic Cluster.  =
Because the galaxies in the Fornax Cluster have different morphologies =
than those of the Local Group, the globular cluster systems are also =
expected to show differences.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.12 Completed WF/PC-2 5758 (WF/PC-2 Imaging of the Protogalaxy =
Candidate B2 0902+34 - LRF Observations)

       The WF/PC-2 was used to make Lyman Alpha observations of the =
protogalaxy candidate B2 0902+34 which is one of the most distant known =
galaxies (Z=3D3.395).  It is hoped to learn more about the distribution =
of star forming regions and emission line gas on smaller scales than was =
possible for previous observations.  The observations were completed as =
scheduled, and no anomalies were reported.

   1.13 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 of an =
emission line survey of the very low excitation planetary nebula =
PK111-02D1 (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.

   1.14 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 =
IRAS18095 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.

   1.15 Completed Two Sets of WF/PC-2 5844 (HST Investigation of a =
Bright, New Comet)

       The WF/PC-2 was used to make observations of the bright new comet =
Hale-Bopp (aka, Comet C/1995 O1).  The images will yield information of =
the nuclear size and coma near the nucleus.  The observations were =
completed as planned, and no anomalies were noted.

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

       FGS#3 was used to make astrometeric observations of extra-galactic =
objects 0637-725IN, 1120-REF, INCA221-39 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.

   1.17 Completed WF/PC-2 6184 (WF/PC-2 Cycle 5 Photometric Calibration =
Monitor UV/OPT STD)

       The WF/PC-2 was used to make ultraviolet and optical observations =
of standard star GRW+70D582 in order to monitor the photometric =
calibrations of the camera and to check for decontamination.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.18 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 object MS1229.2+6 in order to study its environment and its 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.

   1.19 Completed WF/PC-2 5908 (New Class Gravitational Lenses)

       The WF/PC-2 was used to try to confirm the nature of the =
gravitational lens candidate QSO-160913, selected during a new radio =
survey.  Observations will be obtained using the F555W and F814W filters. =
 The observations were executed as scheduled, and no anomalies were =
noted.

   1.20 Completed FOS/RD 5823 (Uranus: Ringlet Kinematics and Atmospheric =
Structures)

       The Faint Object Spectrograph (Red Side) was used to make high =
resolution spectrographic observations of the planet Uranus, its moon =
Titania, and a ringlet segment as a background star passed through the =
Uranian system.  The observations will provide information about the =
planet's atmosphere and its rings.  The observations were executed as =
scheduled, and no anomalies were noted.
