1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three 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 MARK609, MARK590 and NGC-1241 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. 

   1.2 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.

   1.3 Completed WF/PC-2 5848 (The Nuclear Disk in the E4 Galaxy NGC-7052) 

       The WF/PC-2 was used to make observations of the E4 class radio galaxy
NGC-7052 to study its nuclear disk and the kinematics of the gas near the
nucleus.  The observations were executed as scheduled, and no anomalies were
noted.)

   1.4 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. 

   1.5 Completed WF/PC-2 5236 (Nuclei of Nearby Normal Galaxies: Cycle 4)

       The WF/PC-2 was used to make observations of nearby galaxy 2237+0305
to obtain luminosity and color gradients, and to search for bright stars,
globular clusters, and interstellar dust.  The observations were executed as
scheduled, and no anomalies were noted. 

   1.6 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 calibration image was also taken. 
All 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 3C66.0 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 FOC/96 6130 (FOC Observations of SN 1987A)

       The Faint Object Camera (f/96) was used to make near ultraviolet
objective prism observations of the supernova SN1987A. Both the supernova
envelope and the circumstellar ring will be studied.  The observations were
completed as planned, and no anomalies were noted.

   1.9 Completed WF/PC-2 6033 (Parallel High Resolution Imaging of Defuse
Objects in the Magellanic Clouds)

       The WF/PC-2 was used to make parallel images of a variety of defuse
objects located in the Magellanic Clouds.  The observations were primarily in
the Balmer lines and stronger forbidden lines, with supplemental continuum
images.  The observations were completed as scheduled, and no problems were
reported.

   1.10 Completed FOS/BL 5539 (Cycle 4 FOS Photometric Monitor)

       The Faint Object Spectrograph (Blue Side) used standard star
BD+28D4211 to calibrate the absolute sensitivity of its detectors.  The
observations were executed as scheduled, and no anomalies were noted. 

   1.11 Completed Three Sets of WF/PC-2 6251 (Medium Deep Survey - Crafting
Test)

       The WF/PC-2 was used in this continuation of the medium deep survey. 
The proposal is targeting rare objects (lenses, peculiar galaxies, faint
stars) and sources related to the faint blue galaxy problem.  This
observation was completed with no reported problems.

   1.12 Completed GHRS/2 5547 (GHRS Side 2 Detector Calibrations: Cycle 4)

       The High Resolution Spectrograph (Side 2) was used to make dark, and
internal flat calibration images to help check the stability of the
detectors.  The observations were completed as planned, and no anomalies were
reported. 

   1.13 Completed FOC/96 5842 (A Search for Ice at the Poles of Ceres)

       The Faint Object Camera (f/96) was used to make observations of the
asteroid 1-Ceres at three ultraviolet wavelengths.  The purpose is to test
for the presence of water ice on the surface near the polar regions of this
asteroid.  The observations were completed as planned, and no problems were
reported.

   1.14 Completed WF/PC-2 5714 (Imaging of UV Bright Stars in Metal Rich
Globular Clusters)

       The WF/PC-2 was used to make observations of the metal rich globular
cluster NGC-6352.  The target was searched with three filters to search for
ultraviolet bright stars and to determine their luminocites and temperatures.
 The observations were executed as scheduled, and no anomalies were noted.

   1.15 Completed GHRS/2 5837 (Ultraviolet Imaging and Spectroscopy of the
Icy Galilean Satellites)

       The GHRS/2 was used to make ultraviolet observations of Jupiter's moon
Ganymede to study the albedo features caused by SO2 absorption.  These
observations will be coordinated with the IUE spacecraft and other ground
based observations.  The observations were completed as planned, and no
anomalies were reported.

   1.16 Completed FGS 6063 (Continuation of Mass Ratio Determination for
Doubles)

     The Fine Guidance Sensors were used to make POS and TRANS mode
astrometric observations of double star L722-22-00.  This binary star system
contains a low mass star and a brown dwarf.  The observations were completed
as scheduled, and no anomalies were noted.

   1.17 Completed GHRS/1 5594 (GHRS Side 1 Sensitivity Monitor: Cycle 4)

       The High Resolution Spectrograph (Side One) was used to make
calibration observations of star BD28D4211 to monitor the long-term
sensitivity of the system.  The observations were completed as planned, and
no anomalies were reported.
