"Live From HST" Television)

       The Faint Object Camera was used to make observations of the planet =
Neptune.  This object was selected by students involved in the Passport to =
Knowledge program.  The observations were completed as planned, and no =
anomalies were reported.

   1.2 Completed Two Sets of WF/PC-2 6363 (The Environments and Host =
Galaxies of BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations of BL-Lac =
objects MS0419.3+1 and IES1248-29 in order to study their environment and =
their host galaxies.  The goal is to investigate systematic trends in the =
host galaxy type, unusual morphological features, nearby companion =
galaxies, etc.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.3 Completed FGS 6049 (Monitoring the Size and Shape of Mira Type =
Stars)

       The FGSs were used to make astrometric observations of the Mira =
class star HD120285 in order to study its size and shape during different =
phases of its pulsation cycle.  The observations were completed as =
planned, and no anomalies were reported.

   1.4 Completed WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were reported.

   1.5 Completed Two Sets of WF/PC-2 5946 (The Stellar Populations of Low =
Surface Brightness Galaxies)

       The WF/PC-2 was used to make observations of the low surface =
brightness galaxies Malin1, V1L4 and V7L3.  The objective of this program =
is to study the stellar population and evolution of these galaxies.  The =
observations were completed as planned, and no anomalies were reported.

   1.6 Completed WF/PC-2 6189 (WF/PC-2 Cycle 5 Calibration: Internal =
Monitor - Vis Flats)

images.  Both photometric and narrow-band filters were used.  The =
observations were executed as planned, and no problems were reported.

   1.7 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 IR14348-14.  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.

   1.8 Completed WF/PC-2 5972 (Determination of the Extragalactic Distance =
Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-2090 =
looking for standard candle Cepheid variable stars.  The purpose of this =
observations is to help estimate the Hubble constant with an accuracy of =
10%.  The observations were executed as scheduled, and no anomalies were =
noted.

   1.9 Completed WF/PC-2 5923 (The Structure of the Emission Line Regions =
of Compact Steep Spectrum)

       The WF/PC-2 was used to make observations of the compact radio =
galaxy 4C12.50 in order to study the structure of the emission line =
regions of its compact steep spectrum.  The goal is to map the emission =
line structure and establish its relationship to the radio structure.  The =
observations were completed as scheduled, and no anomalies were reported.

   1.10 Completed FOS/RD 6039 (The Young , Rapidly-Evolving Planetary =
Nebula HE3-1357)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the young, rapidly evolving planetary =
nebula HE3-1357 (Sector O).  It appears that this planetary nebula is no =
older than 40 years.  The evolution of this object should allow a strict =
test of the models and theories for the early evolution of planetary =
nebulae.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.11 Completed Three Sets of WF/PC-2 6183 (WF/PC-2 Cycle 5 Calibration: =
Decon)

       The WF/PC-2 was used to make some internal flat, K-Spot, and dark =
calibration images.  The purpose is to define decontamination procedures =
to be run during Cycle 5.  The calibration observations were completed as =
scheduled, and no anomalies were reported.

   1.12 Completed WF/PC-2 6507 (NGC-3664 A Case Study of Shock Induced =
Propagation of Star Formation)

       The WF/PC-2 was used to make observations of the galaxy NGC-3664 in =
order to study shock induced propagation of star formation.  =
Multi-wavelength ground based observations indicate that star formation =
preferentially occurs along the rim and at the edges of the giant gas =
shells of this irregular galaxy.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.13 Completed GHRS/1 5413 (The Local ISM Flow Within the Heliosphere)

interstellar lines in its spectrum.  These exposures are designed to =
detect the weak absorption lines produced by molecules, heavy elements and =
high ionizations.  The observations were completed as planned, and no =
anomalies were reported.

   1.15 Completed FGS 6269 (Parallax of TV COL)

       The WF/PC-2 was used to make snapshot survey observations of spiral =
galaxy IC4390 in order to study its central bulge.  The aim is to =
investigate the core properties, correlation's 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.

       There was an acquisition failure at 071/0210Z when the search limit =
flag was exceeded.  A subsequent FHST map showed bad attitude, and an =
ARU/PRT was performed at 071/0232Z.  The re-acquisiton at 071/0346Z was =
