1.1 Completed WF/PC-2 5774 (WF/PC Augmentation: Cygnus Loop Cycle 4 and
Future-Cycle Continuation)

The WF/PC-2 was used to make observations of NGC-6995-A, which is a
cloud in the Cygnus Loop which has recently been encountered by a
shock wave. The observations were completed as planned, and no
problems were reported.

1.2 Completed FOS/RD/BL 5532 (FOS Dark Monitoring)

The Faint Object Spectrograph (Red and Blue Sides) was used to
monitor the instrument's background (dark) images. The observations
were executed as scheduled, and no anomalies were noted.

1.3 Completed WF/PC-2 5204 (The disks Around Young Stellar Objects)

The WF/PC-2 was used to make images of the disk around the young
proto-star SAO76411A located in the Taurus molecular cloud to learn
about its physical properties such as albedo, particle size, and
spatial distribution. The observations were executed as scheduled,
and no problems were reported.

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

The WF/PC-2 was used to make snapshot images of radio galaxy 3C68.2
as part of a continuum survey and to study the galaxy's morphology.
The observations were executed as scheduled, and no anomalies were
noted.

1.5 Completed 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 WAS87 and NGC-625 to study the
interactions between the central engine, the stars, and the
interstellar matter in their AGNs. The observations were executed as
scheduled, and no anomalies were noted.

1.6 Completed WF/PC-2 5401 (Luminosities and Morphologies of a Complete
3CR Sample of Radio Galaxies)

The WF/PC-2 was used to obtain images of radio galaxies GSC4663-00 and
3C2, which has a Z near 1.0, and also are quasars. These
observations will be used to determine and compare luminosities, and
morphologies in the optical and infrared. The observations were
executed as scheduled, and no anomalies were noted.

1.7 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.

1.8 Completed WF/PC-2 5571 (WF/PC-2 Cycle 4 Calibration: Earthflats,
Smaller Set)

The WF/PC-2 was used to make several ultraviolet and narrow-band
filter Earth flat calibration observations to correct for the
telescope's illumination pattern. The observations were completed as
planned, and no problems were reported.

1.9 Completed Two Sets of WF/PC-2 5655 (WF/PC-2 Cycle 4 Calibration:
Internal Monitor. 2: Flats Part 2)

The WF/PC-2 was used to make a visual flats calibration image. The
observations were completed as planned, and no problems were
reported.

1.10 Completed Two Sets of FOC/96 5437 (UV Spectroimaging of Saturn and
Search for Exogenous Water in the Atmosphere)

The Faint Object Camera (f/96) was used to make ultraviolet images
of the north and south hemisphere of the planet Saturn to look for
upper atmosphere features due to water absorption. The observations
were executed as planned, and no problems were reported.

1.11 Completed WF/PC-2 5399 (Ultra-Deep HST Imaging fo the Hawaii Deep
Survey Fields)

The WF/PC-2 was used to make ultra-deep observations of object
SSA22. These fields of view have already been imaged with ground
based telescopes, and with the Faint Object Camera, to survey the
galaxy populations. The observations were executed as scheduled, and
no anomalies were noted.

1.12 Completed FGS 5752 (Monitor the Long Term Stability of FGS #3:
Revised)

The FGS #3 will be used to make a large number of observations of
stars located in open cluster M-35. (i.e., OF41-REF, OF77-REF,
OF49-REF, OF23-REF, OF4-REF, OF10-REF, OF53-REF, ET AL.). This is a
continuation of Proposal # 5118, looking for long term changes in
the geometric distortion and plate scale. The observations were
executed as scheduled, and no anomalies were noted.

1.13 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4)

The WF/PC-2 was used to make observations taken in parallel with the
prime science observations. This is part of a survey to take
pictures of a large number of fields within 30 degrees of the
galactic plane. The observations were completed as planned, and no
problems were reported.

1.14 Completed Two Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and
Spiral Galaxies: A PC Snapshot Imaging)

The WF/PC-2 was used to make observations of the core region of
galaxies IC342 and NGC-4245 to provide statistics on their nuclear
cups, stellar condensations, and inner stellar disks and dust lanes.
The observations were executed as scheduled, and no anomalies were
noted.

1.15 Completed WF/PC-2 5454 (Ellipticals with Kinematically Distinct
Cores: Cycle 4 Medium)

The WF/PC-2 was used to make observations of the small elliptical
galaxy NGC-5322 which contains a massive core which is kinematically
distinct from the rest of the galaxy. The observations were executed
as scheduled, and no anomalies were noted.

1.16 Completed WF/PC-2 1070 (High Resolution Imaging of Radio Galaxies at
Large Redshift)

The WF/PC-2 was used to make deep images of radio galaxy 3C252 to
study the evolution of its stellar population and to look for star
formation. There was a baseline guide star acquisition failure at
331/0009Z. The acquisition failed to obtain fine lock, and the
observation was completed in single star course track using FGS #1.

1.17 Completed FOS/BL 5444 (A UV Spectral Library of Metal- Poor Massive
Stars)

The FOS (Blue Side) was used for a snapshot program to obtain
ultraviolet spectra of BI272, a metal-poor star in the LMC. It will
be useful for stellar atmosphere and stellar evolution studies. The
observations completed without incident.

1.18 Completed FOS/BL 5682 (UV Spectra of Low-Redshift QSOs
Augmentation: Cycle 4, Carry-over)

The Faint Object Spectrograph (Blue Side) was used to make
ultraviolet spectrographic observations of low redshift QSO
PG0026+12. The observations were executed as scheduled, and no
anomalies were noted.

1.19 Completed WF/PC-2 5091 (GTO High Latitude Parallel Program: Cycle
4)

The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations greater than +/-30
degrees. The observations were executed as scheduled, and no
problems were reported.

1.20 Completed WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4 Medium, High
Galactic Latitude)

The WF/PC-2 made a series of observations of high latitude objects
as part of a medium deep sky survey. The observations were taken in
parallel with other prime science observations. The observations
were completed as scheduled, and no anomalies were noted.
