1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6887 (A Photometric Search for Faint Companions =
to Nearby Stars)

       The WF/PC-2 was used to make photometric search observations of =
the nearby star HD201091 in order to look for possible companions.  The =
technique involves use of the planetary camera with wide band pass =
filters to photometrically measure for the presence of resolved dark =
companions.  The observations were executed as scheduled, and no =
anomalies were noted. 

   1.2 Completed FGS 6538 (The Distances to Dwarf Novae, and the =
Calibration of the Technique of Infrared Spectroscopic Parallax)

       The FGSs were used to make astrometric observations of the dwarf =
novae SS-Aug and several other reference stars in order to measure its =
distance from its parallax.  The distances to this dwarf novae is poorly =
known.  This deficiency severely impacts our ability to quantify the =
energetics of the various processes taking place in dwarf novae systems.  =
The observations were executed as scheduled, and no anomalies were noted. =


   1.3 Completed Two Sets of WF/PC-2 6361 (High Resolution Imaging of =
X-Ray Selected AGNs)

       The WF/PC-2 was used to make high resolution  observations of the =
known, low, red-shifted, x-ray active galactic nucleus (AGN) MS0321.5-6.  =
These data will allow a study of the optical properties of an unbiased =
sample of AGN host galaxies.  The observations were completed as =
scheduled, and no problems were reported.

   1.4 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS =
Galaxy Sample-Part 1:High)

       The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous IRAS galaxy QDOTULIR11.  These data will be searched for =
multiple cores, which imply a merger has occurred, and for starburst =
regions.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.5 Completed WF/PC-2 6443 (High Resolution Imaging of the Luminous =
Infrared Source IRAS 09104+4109)

       The WF/PC-2 was used to make high resolution images of the =
luminous infrared source IRAS09104+4109.  The nuclear spectrum from an =
IRAS survey indicates the presence of a dust enshrouded quasar, yet the =
apparent ionizing flux of the AGN falls short of that required to produce =
the infrared luminosity by a large factor.  The observations were =
executed as scheduled, and no anomalies were noted. 

   1.6 Completed WF/PC-2 6837 (The Ultraviolet Properties of "Dwarf" =
Seyfert 1 Nuclei)

       The WF/PC-2 was used to make ultraviolet observations of the =
"dwarf", type one, Seyfert galaxy NGC-4750.  This class of "dwarf" =
Seyfert populate the faint end of the local AGN luminosity function and =
hold important clues to the evolution of the entire AGN population.  The =
observations were completed as scheduled, and no problems were reported. 

   1.7 Completed WF/PC-2 6359 (Core Properties of the Bulges of Spiral =
Galaxies)

       The WF/PC-2 was used to make snapshot survey observations of =
spiral galaxy NGC-3067 in order to study its central bulges.  The aim is =
to investigate the core properties, correlations with global galactic =
properties, and the frequency of occurrence of multiple and/or =
miscentered nuclei.  The observations were completed as scheduled, and no =
anomalies were noted.

   1.8 Completed STIS/CCD 7099 (CCD Flat-Field Stability and Cosmetic =
Defect Fraction)

       These observations were used to verify cosmetic defect fraction on =
the CCD using flat-field images, and to  investigate flat-field stability =
over short (minutes) and
long (days) time intervals.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.9 Completed WF/PC-2 6352 (Dwarf Elliptical Galaxy Snapshots)

       The WF/PC-2 was used to survey VCC503, from a sample of 30 dwarf =
elliptical galaxies.  The observations were completed as planned, and no =
anomalies were reported.

   1.10 Completed WF/PC-2 6660 (White Dwarf Distance and Precision Age =
For Globular Clusters)

       The WF/PC-2 was used to make observations of the white dwarfs =
which are located in the globular cluster NGC-6752.  This proposal is =
aimed at using the white dwarf cooling sequence for the calibration of =
the globular cluster distance scale.  The determination of accurate =
distances is a critical prerequisite for the estimate of reliable cluster =
ages.  The observations were completed as planned, and no anomalies were =
reported.

   2.3 Operations Notes: 

       NICMOS was transitioned from SAA operate to boot at 085/2031Z.  =
The NICMOS best PAM position was updated at 085/2047Z.  At 085/2148Z the =
NICMOS heaters were turned off.

       A TTR was written due to a misconfiguration of the TDRS frequency =
in the SHO for the event at 086/0113Z.
