1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Five Sets of FOS/RD 6236 (FOS Cycle 5: Location of Spectra
and Wavelength Calibration: Red Side Detector)

       The Faint Object Spectrograph (Red Side) was used to make calibration
observations in order to determine the location of the spectra and to perform
a wavelength calibration.  All observations were internal.  A Taled
calibration was also completed.  The observations were completed as planned,
and no anomalies were reported.

   1.2 Completed Three Sets of WF/PC-2 5957 (Snapshot of 3CR Radio Galaxies)

       The WF/PC-2 was used to make observations of radio galaxies 3C192.0,
3C220.1 and 3C171.0 to study the morphology of these radio galaxies.  The
observations were executed as scheduled, and no anomalies were noted.

   1.3 Completed FOS/BL 6220 (NE VIII Emission in the QSO PG1148+549)

       The Faint Object Spectrograph (Blue Side) was used to make
observations of the bright quasi-stellar object PG1148+549 to study its Neon
VIII emissions.  If Neon VIII emission is visible in this object, it suggests
there is a new emission component in the broad emission line region in QSOs. 
The observations were executed as scheduled, and no anomalies were noted.

Planetary Nebula Nuclei)

       The WF/PC-2 was used to make snapshot survey observations of planetary
nebulae NGC-6720 and A16 to study their nuclei and to look for possible
companions.  The observations were executed as scheduled, and no anomalies
were noted.

   1.5 Completed Three Sets of GHRS/1 5417 (A Search for the Physical
Processes on Jupiter)

       The High Resolution Spectrograph (Side One) was used as part of a
program to observe atomic hydrogen emission at different latitude and
longitudes on the planet Jupiter.  The observations were completed as
planned, and no anomalies were reported.  A wave calibration and sky
background observations were also taken. 

   1.6 Completed FOS/RD 6031 (UV Spectroscopy of Two Very C-Poor Halo
Planetary Nebulae)

       The Faint Object Spectrograph (Red Side) was used to make ultraviolet
observations of the carbon poor planetary nebula PK004-03.1.  This will make
it possible to learn more about the evolution of low mass stars and the
relationship between the interstellar medium and these stars.  The
observations were completed as planned, and no problems were reported.

   1.7 Completed Two Sets of  WF/PC-2 5971 (HST Medium Deep Survey)

       The WF/PC-2 was used to make a long exposure medium deep sky survey
observations at latitudes larger than 10 degrees taken in parallel with the
prime science observations.  The observations were executed as scheduled, and
no anomalies were noted

   1.8 Completed Five Sets of GHRS/1 6171 (CRIMP1: Cycle 5 Condensed-Regimen
Integrated Monitoring Program)

       The High Resolution Spectrograph (Side One) was used  to obtain darks,
internal flats (in photoscan mode), wavelength calibrations and observations
of standard star BD+28D4211.  This includes detector calibration, sensitivity
monitoring, and wavelength monitoring.  The observations were executed as
scheduled, and no anomalies were noted. 

   1.9 Completed Three Sets of FGS 6181 (Red/Blue ND TF Calibrations)

       The FGSs were used to make TRANS Mode astrometric observations of
stars HD28149, HD59149 and HD28484 to obtain reference transfer functions for
the astrometry FGS through the neutral density filter at the center of the
field of view of the instrument.  The observations were executed as
scheduled, and no problems were noted.

   1.10 Completed Three WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking
ultraviolet observations running concurrent 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.

   1.11 Completed GHRS/1 5866 (NLTE Spectral Analysis of PG1159 Type Stars)

       The High Resolution Spectrograph (Side One) was used to make a NLTE
spectrographic analysis of STAR-07045 to study the GW Vir instability strip
and the photospheric parameters and composition.  The observations were
completed as planned, and no problems were reported.

   1.12 Completed GHRS/1 6168 (GHRS PHA/Ion/Threshold Adjustment Test-Cycle
5)

       The High Resolution Spectrograph (Side One) was used to run the
standard pulse height analysis (aka, PHA), and to make internal flat
calibration images, ion and threshold adjustments, and a dark calibration
image.  These are internal observations, which will be used to determine the
best threshold setting for each diode.  During the execution of this
proposal, a status buffer message occurred at 261/2248Z stating that an
observation had been terminated by the NSSC-1 due to an excessive number of
bad quality data errors.  HSTAR 5290 was written.

   1.13 Completed WF/PC-2 5913 (Low Mass Binaries and the Luminosity
Function. )

        The WF/PC-2 was used to make observations of the low mass binary star
system SPG010 (a late-type M class dwarf) to study the  local stellar
luminosity function.  The observations were executed as scheduled, and no
anomalies were noted.

   1.14 Completed WF/PC-2 6227 (The H II/PDR Interface and Other Small Scale
Structure in H II Regions)

       The WF/PC-2 was used to make observations of the H II region known as
the Hourglass within M-8 (aka, the Lagoon Nebula in Sagittarius) to study the
H II/PDR interface and other small scale structures.  The Hourglass presents
a good opportunity to study a photo-evaporative flow driven by an extremely
intense radiation field.  The observations were completed as scheduled, and
no problems were reported.

   1.15 Completed FGS 6175 (Three Points of Light Calibration)

       The FGSs were used in the Trans Mode to make reference transfer
function astrometric observations of standard star UPGREN69 to make a three
points of light calibration.  Observations were made using three different
filters at three different locations in the "pickle".  The observations were
completed as planned, and no anomalies were reported.

   1.16 Completed WF/PC-2 6250 (WF/PC-2 Cycle 5 Calibration: Internal
Monitor)

K-Spot calibrations to monitor the health of the cameras.  The observations
were executed as scheduled, and no problems were reported.

White Dwarf Rotation)

      The High Resolution Spectrograph (Side One) was used to make
observations of the white dwarf nova star U-Gem after a period of outbursts. 
The observations were completed as scheduled, and no anomalies were reported.

   1.18 Completed Two Sets of WF/PC-2 5999 (The Nuclear Structure of S0
Galaxies: A PC Imaging Survey)

       The WF/PC-2 was used to make observations of S0 class galaxies
NGC-6861 and NGC-474 in order to study their nuclear structure.  This is a
part of a large survey of S0, E/S0, and S0/a class galaxies.  The targets
will cover a wide range in luminosity and environment.  The observations were
completed as planned, and no anomalies were noted.

Alpha SCO From CS Lines)

       The High Resolution Spectrograph (Side One) was used to make
observations of star HD148479 which is the binary companion of star Alpha Sco
(aka, Antares) to study its mass loss and curcumstellar composition.  The
observations were completed as planned, and no anomalies were noted.

   1.20 Completed GHRS/2 6322 (Weak Interstellar Lines in the Spectrum of Xi
Persei)

       The High Resolution Spectrograph (Side Two) was used to make
observations of star HD24912 (aka, Xi Persei) to study the weak interstellar
lines of C II and Si II.  The observations were executed as scheduled, and no
anomalies were reported.

   1.21 Completed FGS 6040 (Ultra-High Angular Resolution of O3 Stars in the
Carina Nebula)

       The FGSs were used in the TRANS Mode to make ultra-high resolution
astrometric observations of the O3 class star HD93205 which is located in the
Carina Nebula.  This is to determine if this object is a single star or a
multiple star system.  The observations were completed as scheduled, and no
anomalies were reported.

       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.
