1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WF/PC-2 6419 (Testing Unified Models With a =
Complete Sample of Seyfert Galaxies)

       The WF/PC-2 was used to make observations of the Seyfert galaxies =
ESO-138-G1 and NGC-3516 to help build a complete survey of the Seyfert =
class of galaxies. This will help test the current model for Seyfert =
class galaxies. This model proposes that all Seyferts have Seyfert-1 =
nucleus, which is surrounded by a torus of gas and dust. The observations =
were completed as planned and no anomalies were noted.

   1.2 Completed WF/PC-2 6119 (Snapshot Survey For Companions of =
Planetary Nebula Nuclei)

       The WF/PC-2 was used to make images of the planetary nebui =
NGC-5979 in order to search for companions to its nuclei.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.3 Completed FOC/96 5962 (Young Globular Clusters in Merging =
Galaxies: Part III)

       The Faint Object Camera (f/96) was used to make observations of =
two merging galaxies (aka, NGC-4038/4039) in order to study its compact =
young blue globular clusters to determine their age, luminocity function, =
and physical properties. The observations were executed as scheduled, and =
no anomalies were noted.

   1.4 Completed Four Sets of WF/PC-2 7553 (Pure Parallel Archive Survey =
II)

       WF/PC-2 parallel observations were obtained in the ultraviolet in =
search for interesting objects. This program is designed to find =
extragalactic sources with near ultraviolet excesses (3000 A0) outside =
the galactic plane and far ultraviolet sources (1600 A0) in the galactic =
plane.  The procedure was executed as scheduled, and no anomalies were =
reported. 

   1.5 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.

   1.6 Completed FOS/BL 6471 (A Bolometric Light Curve For Pulsating =
Helium Star LSS3184)

       The Faint Object Spectrograph (Blue side) make spectrographic =
observations of extreme helium, pulsating star LSS3184 in order to study =
it bolometric. This star varies in a period of over 2.5 hours, which is =
identical to the pulsating helium star V652. The observations were =
executed as scheduled, and no anomalies were noted. 

   1.7 Completed Four Sets of WF/PC-2 6802 (Cosmology with The Medium =
Deep Survey)

       The WF/PC-2 was used to make observations in parallel with the =
prime science observations as part of the Medium Deep Survey.  These =
parallel MDS exposures have provided unique high resolution images which =
clearly supplement the primary HST surveys.  The observation were =
executed as scheduled, and no anomalies were noted 

   1.8 Completed GHRS/2 6501 (Probing the Equatorial Ejecta of Eta =
Carinae)

       The GHRS remains safed. The low voltage power supply was turned =
off at 038/1605Z.  No observations were taken.

   1.9 Completed WF/PC-2 7203 (Cosmology with the Medium Deep Survey - =
Short Orbit Cases)

       The WF/PC-2 was used to take short (about 20 minute) exposures, to =
be taken in parallel with the prime science observations, using the I =
filter. These exposures are part of the medium-deep survey, which =
emphasizes exposures that will be useful in obtaining cosmological =
parameters. The observations were completed as planned, and no problems =
were reported.

   1.10 Completed Three sets of 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.

   1.11 Completed WF/PC-2 6619 (High Resolution Images of QSO Lyman Alpha =
Absorbing Galaxies)

       The WF/PC-2 was used to make several images of galaxy field (Field =
1427) in order to obtain high resolution observations of the Lyman Alpha =
absorbing galaxies within this field-of-view. The purpose is to directly =
identify the objects responsible for low and intermediate redshift QSO =
Lyman-Alpha systems.  The observations were executed as scheduled, and no =
anomalies were noted. 

   1.12 Completed Two Sets of GHRS/1 6760 (The Second Measurement of D/H =
in Mars' upper Atmosphere)

       The GHRS remains safed. The low voltage power supply was turned =
off at 038/1605Z.   No observations were taken.

   1.13 Completed GHRS/1/2 6410 (Low Red Shift Lyman Alpha Clouds: )
       The GHRS remains safed. The low voltage power supply was turned =
off at 038/1605Z.   No observations were taken.

Even though the low voltage was powered and no observations were taken, =
there was a re-acquisition failed at 039/0738Z which defaulted to RGAs. =
See HSTAR 5892.

   1.14 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 Q0351-390. 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.

   1.15 Completed FOS/BL 6682 (Geometry and Generalizability of the =
Reflected Light Model for Seyfert Galaxies)

   The Faint Object Spectrograph (Blue side) was used to make =
spectropolarimetry observations of the Seyfert (class 2) galaxy NGC-5135 =
in order to study its geometry and the generalizablity of its reflected =
light model. The goal is to determine if the polarization components of =
all Seyfert class two galaxies have Seyfert class one characteristics. =
The observations were completed as scheduled, and no problems were =
reported. 

   1.16 Completed WF/PC-2 6053 (Extreme UV Stars in Omega Cent)

   The Faint Object Spectrograph (Blue Side) was used to make =
spectrographic observations of extremely ultraviolet bright stars in =
NGC-5139 (aka, Omega Cent). These stars were also viewed by the UIT on =
ASTRO-1. The observations were executed as scheduled, and no anomalies =
were noted.

   1.17 Completed Two Sets of GHRS/1/2 6928 (GHRS Far UV Throughput =
without Costar Mirrors-Cycle 6 Close-out)

       The GHRS remains safed. The low voltage power supply was turned =
off at 038/1605Z.   No observations were taken.

1.18 Completed WF/PC-2 6348 (Blue Continuum Snapshots of 3CR Radio =
Galaxies)

       The WF/PC-2 was used to make some snapshot images of the blue =
continuum in radio galaxy 3C469.1. Combined with existing data, these =
exposures will provide high spatial resolution information on the color =
distribution within galaxies, redding due to dust, spacial indices of the =
optical synchrotron jets, and colors of the active nuclei and tidal jets. =
The observations were executed as scheduled, and no anomalies were noted.

   1.19 Completed WF/PC-2 6942 (WF/PC-2 Camera Electronics)

       The WF/PC-2 was used to make an observations of giant, elliptical, =
galaxy NGC-4472 in order to study the linearity of  the camera's =
electronics.  The observations were completed as planned and no anomalies =
were reported. 

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