1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/RD 5684 (Geometry and Generalizability of the Reflected
Light Model for Seyfert Galaxies)

       The Faint Object Spectrograph (Red Side) was used to make polarization
observations near the nucleus of Seyfert galaxy MARK463E to test the theory
that the Seyfert galaxies actually have Seyfert Type I cores, obscured by
surrounding matter. The observations were completed as scheduled, and no
problems were reported.

   1.2 Completed FOS/BL 5095 (Spectra at Lambda <3000 Angstroms for QSOs with
Z~2 (FOS 3): Cycle 4)

       The Faint Object Spectrograph (Blue Side) was used to make ultraviolet
spectral observations of the absorption lines and high-ionization emission
lines in QSO PKS0109+17. The observations were executed as scheduled, and no
problems were noted. 

   1.3 Completed WF/PC-2 5981 (Calibration of Nearby Type IA Supernova as
Standard Candles: NGC-4639)

       The WF/PC-2 was used to make observations of Cepheid variable stars in
Galaxy NGC-4639 (which has produced a Type IA Supernova) to calibrate the
nova's absolute brightness so that it can be used as a standard candle for
distance measurements.The observations were executed as scheduled, and no
anomalies were noted.

   1.4 Completed WF/PC-2 5985 (WF/PC-2 B-Band + Lyman Alpha Imaging of a
Cluster of Young Galaxies at Z = 2.0)

       The WF/PC-2 was used to make B-Band and Lyman Alpha observations
(i.e., two color images) of the young dwarf spheroidal  galaxy 53W002 located
in Draco and which has a redshift of around 2.0. The observations were
executed as planned, and no problems were reported

   1.5 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal Monitor.
1) 

       The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the optical
alignment, and to check for contamination. The observations were completed as
planned, and no anomalies were noted. 

   1.6 Completed WF/PC-2 6234 (Stellar Populations in the Dwarf Spheroidal
Galaxy Draco)

       The WF/PC-2 was used to make two color observations of a dwarf
spheroidal galaxy located in Draco to study its stellar population and its
star formation history. The observations were executed as scheduled, and no
anomalies were noted.

   1.7 Completed WF/PC-2  5476 (Continuum Snapshots of 3CR Radio Galaxies) 

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C460.0
as part of a continuum survey and to study the galaxy's morphology. The
observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance
Scale: Cycle 4 High)

       The WF/PC-2 was used to make images of galaxy NGC-4414 to be used in
measuring the periods of Cepheid variable stars within this galaxy. The
observations were completed as planned, and no anomalies were noted.

   1.9 Completed FOS/RD 5535 (Cycle 4 Internal Wavelength Calibration)

       The Faint Object Spectrograph (Red Side) was used to make internal
calibration observations to monitor the stability of the wavelength scale for
different gratings. A wavelength calibration observation was also taken. The
observations were completed as planned, and no problems were reported.

   1.10 Completed  WF/PC-2 5239 (Miscellaneous (WC18) Supplemental: Post-ERO
Observations of  Eta Car) 

       The WF/PC-2 was used to make observations of Eta Carinae searching or
interesting features and to provide second epoch information on the nebula
for comparison with earlier observations. The observations were executed as
scheduled, and no anomalies were noted. 

   1.11 Completed Two Sets of WF/PC-2 5479 (Subarcsecond Structure in Nearby
AGNs)

      The WF/PC-2 was used to make snapshot observations of the nearby active
galactic nuclei of NGC-788, IC184, PG0003+199 and IR0147-076 to study the
interactions between the central  engine, the stars, and the interstellar
matter in these AGNs. The observations were executed as scheduled, and no
anomalies were noted. 

   1.12 Completed GHRS/2 5424 (High Resolution Observations of the Jovian UV
Aurora: Cycle 4 Medium)

       The High Resolution Spectrograph was used to make high resolution
ultraviolet spectrographic observations of the aurora on the planet Jupiter
short of 2000 A0. The goal is to determine the kinetic temperatures of the
auroral region and the range of altitudes over which precipitating auroral
particles deposit their energy and H2 Lyman and Werner Band emissions. The
observations were executed as scheduled, and no anomalies were noted.

   1.13 Completed WF/PC-2 5706 (Morphology of Distant Galaxies - Cycle 4
Carryover)

       The WF/PC-2 was used to make observations of a field of view
designated as Field-0017. This is part of a study of the morphology of
distant galaxies. The observations were completed as planned, and no problems
were reported.

   1.14 Completed WF/PC-2 5701 (Galaxy Populations in Intermediate Redshift
Clusters: Cycle 4)

       The WF/PC-2 was used to observe fields in the Abell galactic cluster
AC103 to study the morphology of the galaxies in the cluster so that they can
be classified and used to learn more about the Butcher-Oemler effect. The
observations were completed as planned, and no problems were reported. 

   1.15 Completed FOS/BL 6146 (FOS Location of Spectra and Aperture - Part 2)

     The Faint Object Spectrograph (Blue Side) was used to conduct a test to
determine the repeatability of positioning the filter-grating wheel. All
observations were internal. A wave length and a dark calibration image were
also taken. All observations were executed as scheduled, and no anomalies
were noted.

   1.16 Completed FOS/BL 5658 (White Dwarf Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make absolute
sensitivity calibrations of the detectors using standard white dwarf star
GD153. The observations were executed as planned, and no anomalies were
noted.

Monitor 1C: 4-Chip STD in F170W)

       The WF/PC-2 was used to make photometric calibration observations of
the ultraviolet standard star GRW+70D582. The observations were executed as

   1.18 Completed GHRS/1 5542 (GHRS Side One Wavelength (1st Order Gratings):
Cycle 4) 

       The High Resolution Spectrograph (Side One) used the spectral
calibration lamp (Side Two) to calibrate the Side One characteristics. Notice
that the Side Two lamp was used to calibrate Side One. The observations were
executed as scheduled, and no anomalies were noted.
