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

   1.2 Completed Two Sets of GHRS/1 6079 (UV Eclipse Spectroscopy of =
Accretion disk Winds)

       The High Resolution Spectrograph (Side One) was used to make =
ultraviolet eclipse spectrographic observations of wind-formed lines from =
the eclipsing cataclysmic binary system UX UMa in order to study its accre=
tion disk winds.  The observations were executed as scheduled, and no =
anomalies were noted. 

   1.3 Completed Four Sets of FOS/BL 6407 (Post Asymptotic Giant Branch =
Evolution in the Magellanic Clouds)

       The Faint Object Spectrograph was used to make ultraviolet =
spectrographic observations of planetary nebulae LMC-SMP99, LMC-SMP63, =
LMC-SMP42 and LMC-SMP55 which are located in the Large Magellanic Cloud.  =
These data should give the spatial structure, size, ionized masses, and =
dynamic ages of these objects.  The observations were executed as =
planned, and no problems were reported. 

    1.4 Completed FOS/RD 6548 (The Cool Interstellar Medium in Hot =
Cluster of Galaxies)

       The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet resonance absorption line observations of quasar QSO0056-01 =
in order to study the cool interstellar medium within a cluster of =
galaxies which lie within the line of sight to the quasar.  The QSO is =
being used a probe of the galactic cluster.  The observations were =
executed as scheduled, and no anomalies were noted. 

   1.5 Completed Two Sets of FOS/RD 6577 (An Expanded Survey for Study of =
the Lyman-Alpha Line and QSO Mg II Absorption)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the QSOs in PG1715+535 and 4C65.15 in order to make a =
survey of the Lyman-Alpha line and the 68 Mg II absorption line system.  =
The observations were completed as scheduled, and no problems were =
reported. 

   1.6 Completed GHRS/2 6710 (Abundances in the Neutral Medium of the =
Compact Galaxy IZW-18)

   The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the compact galaxy IZW-18 in order to =

observations of low-mass nearby star LHS292 to search for possible faint =
companions.  The bright star was placed behind an occulting bar.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed WF/PC-2 5966 (The Origin of the Alignment Effect: =
Spectroscopy and Imaging of Radio Sources)

       The WF/PC-2 was used to make images of the radio galaxy 3C368.  =
The WF/PC-2 will be used to image the galaxy at continuum and emission =
line wave lengths, and the images will be used to determine the position =
at which the FOS will later be used to observe the emission line =
spectrum.  Near the beginning of this ten and one-half hour proposal, t =
314/0203Z, there was an FOS target acquisition failure that was reported =
in HSTAR 5792.  Any possible affect on science is not currently known.  =
Otherwise, the observations completed as planned, and no further =
anomalies were reported.  

   1.9 Completed WF/PC-2 6338 (Colors, Parallax and Orbit of GL229B)

       The WF/PC-2 was used to observe GL229B, a recently discovered =
companion to the M-dwarf star GL229A (aka, HD42581).  Methane has been =
detected in the spectrum of GL229B, and the evidence suggests that it has =
a mass of only 20 Jupiter masses, and a temperature of less than 1000 K.  =
The WF/PC-2 will obtain astrometric and photometric data of GL229B, and =
will also search for other possible companions.  The observations =
completed as scheduled, and no problems were reported.

   1.10 Completed GHRS/1 6638 (Physics of Defuse Clouds in the Local =
Bubble, Part 1)

       The High Resolution Spectrograph (Side One) was used to make =
observations of star HD50013 (aka, the Canus Major "Tunnel") in order to =
study the physics of the defuse clouds in the local bubble.  This high =
resolution spectroscopy will enable the proposers to characterize the =
interface between diffuse clouds and the hot bubble, measure the =
ionization state and depletion level on the local environment.  During =
this proposal, at 314/1520Z, there was a loss of lock that was documented =
in HSTAR 5793.  Otherwise, the observations were executed as scheduled, =
and no further anomalies were noted.

   1.11 Completed FOS/BL 6643 (Supersoft Sources in the LMC)

The  Faint Object Spectrograph (Blue Side) was used to make observations =
of the supersoft source  (aka, SSS) CAL83 which is located in the Large =
Magellanic Cloud.  This is a new class of objects characterized by their =
high luminosity and extreme soft X-ray spectra.   The observations were =
executed as scheduled, and no anomalies were reported. 

   1.12 Completed Two Sets of FOS/RD 6025 (Consequences of the =
Shoemaker-Levy Impact With Jupiter)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the planet Jupiter in order to study the =
consequences from the impact of the comet Shoemaker-Levy.  This is to =
study the atmosphere following the impact to measure the chemical =
abundances as a function of time.  The observations were completed as =
scheduled, and no problems were reported.

   1.13 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.

   1.14 Completed FGS 6764 (Detection and Mass Determination of Low Mass =
Companions)

       The FGS were used in both the TRANS and POS modes to make =
astrometric measurements of nearby, dwarf, M class star GL791 in order to =
measure the mass of its possible low mass companion.  The intent is to =
improve the mass-luminosity relation for the cool end of the main =
sequence.  The observations were executed as scheduled, and no anomalies =
were noted. 

   1.15 Completed FOC/96 6349 (Snapshot search for High Redshift QSOs =
with Far-UV Flux)

       The Faint Object Camera (f/96) was used to make snapshot images of =
the quasi-stellar object Q2043-340.  This is to determine if this high =
redshifted object has a far ultraviolet flux.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.16 Completed GHRS/2 6455 (Metal Diffusion and Radiative Levitation =
in Hot Helium Rich White Dwarfs)

       The High Resolution Spectrograph (Side Two) was used to make =
spectrographic observations of the hot, helium-rich, white dwarf star =
HS0111+001 in order to study its metal diffusion and radiative =
levitation.  The data will be used to search for weak photospheric metal =
absorption lines which were too weak to be observed at optical =
wavelengths.  The observations were executed as planned, and no anomalies =
were reported. 

   1.17 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 Q0122+3152 whose light passes through the galaxy  M-33.  This =
allows for one to probes into the interstellar medium in outer disk and =
halo of galaxy M-33.  The observations were completed as planned, and no =
problems were noted. 

   1.18 Completed WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: Earth Flats)

       The WF/PC-2 was used to make observations of the bright Earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.19 Completed WF/PC-2 6902 (WF/PC-2 Cycle 6 Photometric Calibration =
Monitor UV/OPT STD)

       The WF/PC-2 was used to make both ultraviolet and optical =
photometric observations of the standard star GRW+70D582 as part of a =
Cycle 6 calibration procedure.  This observations was done immediately =
before and after decontamination procedures.  Near the end of this =
one-hour propopsal, at 316/193136Z, a loss of lock occurred during a =
WF/PC-2 dwell scan.  This event is described in HSTAR 5795.  Otherwise, =
the observations completed as planned, and no further problems were =
reported. 

   1.20 Completed FOS/RD 6417 (Star Formation in the Prototype Super =
Cluster R136)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the star formation in the prototype super =
star cluster R136 in order to study its intense star formation regions.  =
This in fact may be the young analog of globular clusters.  The =
observations were completed as scheduled, and no problems were reported.
