Daily Status Report as of 029/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images.  =
These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.2 Completed FGS 6045 (The Masses of the O-Type Binary 15 Monocerotis)

       The FGSs were used to make TRANS Mode astrometric observations of =
the O class binary star HD47839 (aka, 15 Monocerotis) to help determine =
its mass.  The goal is to measure the separation, position angle, and =
magnitude difference of this binary system.  The observations were =
executed as scheduled, and no anomalies were noted. 

   1.3 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.

   1.4 Completed WF/PC-2 6129 (The Structure, Polarization, and Evolution =
of the Crab Synchrotron Nebula)

       The WF/PC-2 was used to make observations of the area near =
Crab-Pulsar (M-1) in order to study its structure, polarization, and =
evolution.  Two color and polarization images were made.  The observations =
were executed as planned, and no anomalies were reported.

   1.5 Completed Four Sets of FOS/BL 6166 (FOS Cycle 5: Location of =
Spectra and Wavelength Calibration)

       The Faint Object Spectrograph (Blue Side) was used to make =
wavelength calibration images to measure the stability of the FOS Blue =
Side wavelength scale and spectral locations.  Taled calibration =
observations was also taken.  The observations were completed as planned, =
and no anomalies were reported.

   1.6 Completed WF/PC-2 5447 (The Nature of Primeval Galaxies)

       The WF/PC-2 was used to make deep polarization observations of the =
distant, massive galaxy TX0828+193 to look for molecular gas, dust, and =
star formation.  The observations were executed as scheduled, and no =
anomalies were noted. 

   1.7 Completed WF/PC-2 6250 (WF/PC-2 Cycle 5 Calibration: Internal =
Monitor)

       The WF/PC-2 was used to make a series on internal calibration =
observations.  Internal flats, biases, and K-Spot calibration images were =
taken.  These observations are designed to monitor the health of the =
cameras.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.8 Completed FGS 6267 (Parallax of Feige 24)

       The FGSs were used in the POS Mode to make astrometric observations =
of the white dwarf star FEIGE 24 and several reference stars in order to =
measure its parallax.  The target is one of the first white dwarfs found =
to be an EUV source and subsequently has been found to be an X-Ray source =
and an interacting binary.  The observations were completed as planned, =
and no problems were reported.

   1.9 Completed Two Sets of WF/P-2 6254 (GTO Pure Parallel Program - =
Cycle 5)

       The WF/PC-2 was use to make random long exposures of high galactic =
fields taken in parallel with the prime science observations to obtain a =
random sample of galaxies.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.10 Completed WF/PC-2 6229 (Stellar Populations in the LMC and the =
SMC)

       The WF/PC-2 was used to obtain images of region HS-275 in the Large =
Magellanic Cloud.  The objective is to construct color magnitude diagrams =
for this region.  The luminosity function and stellar formation history of =
the cloud will then be derived.  The proposal completed uneventfully.

   1.11 Completed FOC/96 6306 (Supernova Light Echoes)

       The Faint Object Camera(f/96) was used to make observations of =
supernovae remnant SN1961V in order to study its light echoes.  Measuring =
the separation of the echo from the site of the supernova gives a direct =
measure of the distance to the parent galaxy.  The echoes are expected to =
be very blue, and highly polarized.  The observations were completed as =
planned, and no anomalies were reported.

   1.12 Completed WF/PC-2 6099 (Black Holes and Cores of Galaxies)

       The WF/PC-2 was used to search for possible black holes in the =
cores of nearby early-typr galaxies NGC-1023 and NGC-484.  The WF/PC-2 =
will be used to obtain high resolution images of several galaxies to =
identify those with bright cores, and to provide sufficiently accurate =
coordinates for the FOS, which will be used to measure the velocity =
dispersion around selected galaxies.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.13 Completed WF/PC-2 6118 (HST Observations of Two Ultraluminous =
Extragalactic Supernova Remnants)

       The WF/PC-2 was used to make observations of the ultraluminous =
extragalactic supernova remnant NGC6946-SN.  This is one of the brightest =
supernova remnants known.  Its high luminosity may be caused by =
interaction with its local environment.  The observations were completed =
as scheduled, and no problems were reported.

   1.14 Completed WF/PC-2 6117 (Fliers in Planetary Nebulae)

       The WF/PC-2 was used to make observations of planetary NGC-6826 in =
order to look for fliers.  A flier is plasma knot embedded within highly =
ionized elliptical and bipolar planetary nebulae.  The observations were =
executed as scheduled, and no anomalies were noted

   1.15 Completed WF/PC-2 5999 (The Nuclear Structure of S0 Galaxies: A PC =
Imaging Survey)

       The WF/PC-2 was used to make observations of S0 class galaxy =
NGC-3607 in order to study its nuclear structure.  This is a part of a =
large survey of S0, E/S0, and S0/a class galaxies.  The targets will cover =
a wide range in luminosity and environment.  The observations were =
completed as planned, and no anomalies were noted.

   1.16 Completed WF/PC-2 6307 (Exploring the Morphology of QSO Absorber =
Galaxies at Redshift Z>3)

GAL-020347 in order to study the morphology of this galaxy which has a =
redshift of greater than Z=3D+3.0.  High redshifted absorption lines are =
known to be in its spectra.  The observations were completed as scheduled, =
and no anomalies were reported.

   1.17 Completed WF/PC-2 6132 (Imaging Young Stellar Objects)

       The Planetary Camera was used to image the environments of T-Tauri =
star IRAS04016.  Analysis of the images will be used to constrain various =
physical parameters including the initial angular momentum of the =
protostellar cloud cores, the radii of circumstellar disks and the =
interaction between highly collimated jets and the protostellar envelopes =
of this young stellar objects.  The observation was executed as scheduled, =
and no anomalies were noted.

   1.18 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 HD84748 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.

   1.19 Completed FOS/RD 6061 (The Spectrum of the bright, Mysterious =
White Dwarf Star Procyon)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the bright, mysterious white dwarf star Procyon B which is =
the binary companion to Alpha-Canis Minoris.  The objective is to =
determine the temperature and chemical composition of this dwarf star, and =
to place Procyon B on the mass-radius relation.  The observations were =
completed as planned, and no problems were reported.

   1.20 Completed WF/PC-2 5983 (Curcumstellar Disks in Young Nebulous =
Clusters)

       The WF/PC-2 was used to make observations of the young nearby =
nebulous cluster NGC-2024-3 looking for possible curcumstellar disks =
(solar nebula analogs), like the type seen in the Orion Nebula.  The =
observations were completed as planned, and no problems were reported.
