       WF/PC-2 parallel observations were obtained in the ultraviolet in =
search for interesting objects.  This program is designed to find =
extragalactic sources with near ultraviolet excesses (3000 A0) outside =
the galactic plane and far ultraviolet sources (1600 A0) in the galactic =
plane.  The procedure was executed as scheduled, and no anomalies were =
reported.

regions.  The observations were completed as scheduled, and no anomalies =
were reported.

   1.9 Completed FOS/BL 6600 (Investigating High Temperature Big Bumps in =
AGNs)

       The Faint Object Spectrograph (Blue Side) was used to make =
observations of the active galactic nuclei in Galaxy ZW212.025 in order =
to investigate its high temperature big blue bumps.  These bumps (or =
lumps) appear to be very hot in both the visual and soft x-rays.  The =

observations were taken in parallel with the prime science observations.  =
They were completed as planned, and no anomalies were reported.

   1.11 Completed GHRS/1 6707 (M-33: An Archetypal QSO Absorption Line =
Galaxy)

       The High Resolution Spectrograph (Side One) was used to make =
observations of the C IV, Si IV, and Si II spectrographic absorption =
lines QSO Q0116+3146 whose light passes through the galaxy  M-33.  This =
allows for one to probe into the interstellar medium in outer disk and =
halo of galaxy M-33.  The observations were completed as planned, and no =
problems were noted. 

   1.12 Completed Two Sets of WF/PC-2 6363 (The Environments and Host =
Galaxies of BL-Lac Objects)
363

       The WF/PC-2 was used to make snapshot survey observations of =
BL-Lac object H1517+656 in order to study its environment and its host =
galaxy.  The goal is to investigate systematic trends in host galaxy =
type, unusual morphological features, nearby companion galaxies, etc.  =

   1.13 Completed FOS/BL/GHRS/1 5947 (The Relationship Between Galaxies =
and Lyman-Alpha Absorbers at Low Redshift)

       The Faint Object Spectrograph (Blue Side) and the High Resolution =
Spectrograph (Side One) were used to make observations of Quasar =
PKS-1217+0 in order to study the relationship between its galaxy and =
Lyman-Alpha absorbers at low redshift.  The relationship between the =
galaxy and low column density, metal poor quasar absorbers is poorly =
understood.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.14 Completed FGS 6047 (Calibrating the Mass Luminosity Relation at =
the End of the Main Sequence)

       The FGSs were used to make astrometric observations of star GJ1215 =
as part of a study to determine its mass luminosity relationship.  The =
purpose is to measure the precise parallax and relative orbit of its =
faint companion.  The observations were completed as planned, and no =
problems were reported.

   1.15 Completed WF/PC-2 6419 (Testing Unified Models With a Complete =
Sample of Seyfert Galaxies)

       The WF/PC-2 was used to make observations of the Seyfert galaxy =
Mark607 to help build a complete survey of the Seyfert class of galaxies. =
 This will help test the current model for Seyfert class galaxies.  This =
model proposes that all Seyferts have Seyfert-1 nucleus, which is =
surrounded by a torus of gas and dust.  The observations were completed =
as planned and no anomalies were noted.

   1.16 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 nucleus (AGN) MS1139.7+1.  =
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.

   1.17 Completed WF/PC-2 6357 (The Nuclear Morphology of Elliptical =
Galaxies)

      The WF/PC-2 was used to make images of the early type, large, =
elliptical galaxy UGC-2681 (taken form a list of 150 galaxies) in order =
to study its nuclear morphology.  This survey will complement =
Illingworth's snapshot study of later Hubble types.  The observations were=
 completed as scheduled, and no anomalies were reported. 

   1.18 Completed FOS/RD 6635 (Unveiling the Nature of Ultraviolet Spike =
at the Center of the SA Galaxy NGC-2681)

       The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet spectrographic observations of the SA class, galaxy NGC-2681 =
in order to study the nature of the ultraviolet bright spike and bulged =
dome in the center of the galaxy.  This feature appeared almost =
point-like in pre-COSTAR images.  The observations were completed as =
planned, and no problems were reported.

   1.19 Completed Two Sets of FOS/RD 6039 (The Young , Rapidly-Evolving =
Planetary nebula HE3-1357)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the young, rapidly evolving planetary =
nebula REV-HE3-13.  It appears that this planetary nebula is no older =
than 40 years.  The evolution of this object should allow a strict test =
of the models and theories for the early evolution of planetary nebulae.  =
The observations were executed as scheduled, and no anomalies were noted.

   1.20 Completed GHRS/2 6456 (The Photospheric Iron Abundance of the UV =
Bright Stars in a Globular Cluster)

       The High Resolution spectrograph (Side Two) wad used to make =
ultraviolet spectrographic observations of five ultraviolet bright stars =
located in the globular cluster NGC-6397 in order to study the stars' =
iron abundances and the prediction given by stellar evolution theory.  =
These ultraviolet bright stars are in a post-AGB stage of evolution, and =
are on the way to becoming white dwarf stars.  The observations were =
completed as planned, and no problems were reported.

   1.21 Completed Two Sets of WF/PC-2 6773 (The Bucher-Oemler Effect in =
Nearby Clusters of Galaxies)

       The WF/PC-2 was used to make observations of several starburst and =
post-starburst regions the nearby galaxies and the coma of Coma-D45.  =
These data will be studied to determine what triggers major episodes of =
star formation and what physically undermines the observed Butcher-Oemler =
effect in more distant galaxies.  The observations were completed as =
planned, and no problems were reported.
