Daily Status Report as of 363/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Twelve Sets of WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental
Darks PT1/3)

       The WF/PC-2 was used to make supplemental dark calibration images.
This set of calibrations is intended to obtain three dark frames every day
to provide data for monitoring and characterizing the evolution of hot
pixels.  During the ninth iteration of this proposal, the 27 minute, five
second loss of lock described in 2.1 occurred, taking down the take data
flag.  Otherwise, the observations were executed as scheduled, and no
further anomalies were noted.

   1.2 Completed Thirty-Seven Sets of STIS/CCD 7783 (STIS Parallel Science)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations taken in parallel with the prime science.  During the
twenty-seventh iteration of this proposal, the 15 second loss of lock
described in 2.1 occurred, taking down the take data flag.  Otherwise, the
observations were completed, and no further problems were reported.

   1.3 Completed Six Sets of STIS/CCD 7802 (Daily Darks to Update
Acquisition Bad Pixel Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations to obtain daily darks to update the acquisition
bad pixel table.  These darks are intended to identify hot pixels for
update to the acquisition on-board FSW hot pixel table.  Daily hot pixel
lists can also be used for science data analysis.  The observations were
executed as scheduled, and no anomalies were noted.

   1.4 Completed NIC/3 7814 (NICMOS Camera 3 Pointed Super Flats)

       The Near Infrared Camera (Camera Three) was used to make a "pointer
super flat" calibration image.  The observations will be used to build high
S/N NICMOS flat fields for the different filters.  Special commanding is
required to move the NICMOS FOM.  The observations was completed as
planned, and no anomalies were reported.

   1.5 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.

   1.6 Completed NIC/1/2/3 7452 (NICMOS Imaging of MuJy Radio Rources With
R>= 29: The Birth of AGN in Pregalactic Objects at Z>=6-10?)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the infrared counterpart of radio source HDF-VLA-36.
The images will be made public and will be used to: {1} determine their kpc
sizes and optical- IR colors; {2} find any obscured AGN, and see what
causes the radio emission; {3} constrain their possible redshift range and
the role of dust; and {4} find the sub-galactic fragments suitable for
NICMOS-grism Cycle 8 follow-up to determine their redshifts.  The
observations were completed as planned, and no porblems were reported.

   1.7 Completed Thirty Eight Sets of STIS/CCD 7781 (STIS Non-Scripted
Parallel Archive Proposal - Full Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one full orbit).  The observations

non-scripted parallel archive proposal (one-half orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.9 Completed Three Sets of WF/PC-2 6473 (A Search for Supernovae at
High Z in the Hubble Deep Field)

       The WF/PC-2 was used to make observations of the Hubble Deep Field
HDF-123649 to search for possible supernovae at high Z values.  This
proposal will serve as a pathfinder to begin delineating SNe event rates at
high Z.  The observations were executed as scheduled, and no anomalies were
noted.

   1.10 Completed Twenty Nine Sets of NIC/2/3 7922 (New NICMOS Modified One
Orbit Parallel)

       The Near Infrared Camera (Cameras One and Two) was used to make one
orbit parallel observations.  This proposal obtains "JH" imaging, and G096
and G141 spectroscopy of sky regions when another instrument is prime.
STEP64 sequences are used and two dither positions are obtained for each
filter.  The observations were executed as scheduled, and no anomalies were
noted.

   1.11 Completed Three Sets of NIC/1/2 7904 (NICMOS Absolute Photometry:
Red Standards)

       The Near Infrared Camera (Cameras One and Two) was used to make
observations of standard sources GD153-CAL, G191B2B and P177D-CAL in order
to execute a red standard absolute photometry calibration.  The throughput
of NIC/1 and NIC/2 will also be measured using P330E and G191B2B.  The
observations were finished as planned, and no anomalies were reported.

   1.12 Completed WF/PC-2 7625 (WF/PC-2 Cycle 7 Earth Flats)

       The WF/PC-2 was used to make a series of Earth flat calibration
images.  These flat fields will allow mapping of the OTA illumination
pattern and will be used in conjunction with previous internal and external
flats to generate new pipeline superflats.  The observations were completed
as planned, and no anomalies were reported.

   1.13 Completed Fourteen Sets of WF/PC-2 7786 (Pure Parallel Archive
Survey - Continuation)

       The WF/PC-2 was used to make observations as part of an archival
survey program in which the images were taken in parallel with the prime
science observations.  These WF/PC-2 parallel observations were obtained in
the ultraviolet in a search for interesting objects.  The acquisition for
the second iteration of this proposal defaulted to fine lock on FGS-3 only
(as described in 2.1).  Then, during the thirteenth iteration of this
proposal, the 15 second loss of lock described in 2.1 occurred, taking down
the take data flag.  Otherwise, the observations were completed as planned,
and no further problems were reported.

   1.14 Completed WF/PC-2 7387 (T-Tauri Star Snapshot Survey)

of a T-Tauri class star survey. The observations were executed as
scheduled, and no anomalies were noted.

   1.15 Completed Two Sets of NIC/2/STIS/CCD/WF/PC-2 7220 (Imaging of
Quasar Host Galaxies)

       The Near Infrared Camera (Camera Two), the Space Telescope Imaging
Spectrograph (CCD), and the WF/PC-2 were used to make direct imaging
observations of the host galaxy for the broad absorption line quasar
QSO0131+05.  During the first iteration of this proposal, the first FGS
default mentioned in 2.1 occurred.  Otherwise, the observations were
completed as planned, and no further anomalies were reported.

   1.16 Completed STIS/CCD 7666 (CCD Linearity and Shutter Stability)

       The Space Telescope Imaging Spectrograph (CCD) was used to make some
CCD linearity and shutter stability calibration checks.  CCDs can suffer
from non-linearities at low, high {or both} intensity.  Such effects can be
subtle, but are an important contributor to error budgets for routine
science observations and are sometimes recognized only after limitations
are detected in careful analyses of science data.  The observations were
completed as scheduled, and no anomalies were noted.

   1.17 Completed Five Sets of STIS/MA2 7649 (STIS MAMA Missed Dispersion
Solutions)

       The Space Telescope Imaging Spectrograph (MA2) was used to obtain
deep engineering wavecals of the two remaining central prime wavelengths of
the E140H and all remaining prime settings for the Echelle gratings E230H
and E230M.  The observations were pure internals, with no external source.
The observations were completed as planned, and no anomalies were reported.


   1.18 Completed Two Sets of WF/PC-2/STIS/CCD/NIC/1/2 7307 (The Formation
and Evolution of Rich Star Clusters in the LMC)

       The WF/PC-2, the Space Telescope Imaging Spectrograph (CCD), and the
Near Infrared Camera (Cameras One and Two) were used to make observations
of the rich star cluster NGC-2209 which is located within the Large
Magellanic Cloud in order to study its formation and evolution.  These
observations will help us understand the origin and evolution of rich star
clusters in our own galaxy.  The observations were complete as scheduled,
and no anomalies were reported.

   1.19 Completed Two Sets of STIS/MA2 7604 (Cycle 7 MAMA Dark Measurements)

       The Space Telescope Imaging Spectrograph (MA2) was used to make MAMA
dark measurements.  These darks will be used in later image reductions and
also trended over the instrument's life time as an indicator of the
detector's degradation or damage.  The observations were completed as
scheduled, and no problems were reported.

   1.20 Completed NIC/1/2 7259 (Polarization Mapping of the Infrared
Emission from the Jet in M87)

       The Near Infrared Camera (Cameras One and Two) was used to make
polarization mapping of the infrared emissions of the jet from the nuclear
region of galaxy M-87 (a.k.a., NGC-4486).  This jet is bright at optical
through x-ray wavelengths.  Being the closest such optical jet it is a
prime target for high resolution imaging with the HST.  The observations
were executed as scheduled, and no anomalies were noted.

   1.21 Completed Three Sets of NIC/1/2/3 7596 (NICMOS MULTIACCUM Dark
Characterization)

MULTIACCUM sequences.  The observations were executed as scheduled, and no
anomalies were noted.

   1.22 Completed Two Sets of STIS/CCD 7711 (STIS CCD G750L Fringing Flats.)

       The Space Telescope Imaging Spectrograph (CCD) was used to
investigate and monitor the STIS CCD flat-field fringing in the G750L
grating at its nominal wavelength setting {7751A}.  WAVECALs were also
taken at the same gain and wavelength setting.  Typical S/N = 100 for each
integration, and gain = 4 on each.  The observations were executed as
scheduled, and no anomalies were noted.

   1.23 Completed WF/PC-2 6134 (Investigating the Nature of Circumstellar
Matter in Young Clusters)

       The WF/PC-2 was used to take broad band images the young star
cluster NGC-1333 associated with a bright reflection nebulae in an attempt
to detect circumstellar (CS) material about the stars in these clusters.
The HST data will be combined with ground based near-IR and millimeter
data.  The combined data is expected to determine the frequency
distribution of CS material and disks in undisturbed young clusters, the
size and mass distribution of CS nebulae, and the correlation of these
properties with stellar luminosity.  The observations were completed as
scheduled, and no problems were reported.

   1.24 Completed STIS/CCD 7674 (IR Standards)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of the standard source BD+28D4211 to establish a set of
absolute flux standards on the WD scale that extend the existing wavelength
coverage to 10300A with the STIS G750L grating setting.  The proposal
completed with no reported problems.

   1.25 Completed NIC/2 7331 (Near-IR Properties of the Bulges of Spiral
Galaxies)

       The Near Infrared Camera (Camera Two) was used to make infrared
observations of the bulges in spiral galaxies NGC-7513, NGC-7280, NGC-3455
and IC273.  Near-IR data at HST resolution are essential for correcting for
the effect of dust and will enable us to derive robust nuclear properties
for the sample.  The observations were executed as scheduled, and no
anomalies were noted.

   1.26 Completed WF/PC-2 6943 (WF/PC-2 Cycle 6: Throughput Verification
for Narrow Band Filters)

       The WF/PC-2 was used to make observations of object K4-47 in order
verify the throughput for the narrow band filters.  This program will
provide direct verification of throughput of narrow band filters through
observations of emission line objects.  The observations were completed as
planned, and no anomalies were reported.

   1.27 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-2985.  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.

   1.28 Completed STIS/CCD 7807 (HDF Test Exposure)

       The Space Telescope Imaging Spectrograph (CCD) was used to make a
series of Hubble Deep Field test exposures.  This is a test exposure to
ensure good guide star selection and proof of concept for future
observations.  These observations were completed as planned, and no
problems were reported.

   1.29 Completed WF/PC-2 7622 (WF/PC-2 Cycle 7 Internal Monitor)

       The WF/PC-2 was used to make a set of Cycle 7 internal monitoring
calibration measurements.  A variety of internal exposures are obtained in
order to provide a monitor of the integrity of the CCD camera electronics
in both bays {gain 7 and gain 15}, a test for quantum efficiency in the
CCDs, and a monitor for possible buildup of contaminants on the CCD
windows.  A bias calibration and an internal flat calibration image were
also taken.  The observations were executed as scheduled, and no anomalies
were noted.

   1.30 Completed 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.

   1.31 Completed NIC/2 7498 (NICMOS Imaging Survey of Distant Radio
Galaxies. Ellipticals at Z > 2 ?)

       The Near Infrared Camera (Camera Two) was used to make high
resolution and high signal-to-noise ratio imaging survey observations of
the radio galaxy MRC0152-20.  The existence and photometric properties of
massive elliptical galaxies at high redshift provide a powerful probe of
galaxy evolution.  The observations were executed as scheduled, and no
anomalies were noted.

   1.32 Completed WF/PC-2 6677 (The Origin of the X-Ray Background: What
are the Faintest X-Ray Galaxies?)

       The WF/PC-2 was used to make observations of the galaxy GAL-133346
which is from the deepest optically identified (ROSAT) X-ray survey yet.
These images were taken to  determine the morphologies of the remaining
systems which we cannot study from the ground to determine whether the
remaining non-QSO XRB might be explained by emission from interacting or
disturbed spirals.  The observations were completed as planned, and no
anomalies were reported.

   1.33 Completed NIC/1/2 7426 (NICMOS Imaging of Red Giants in M-32)

       The Near Infrared Camera (Cameras One and Two) was used to make
observations of red giant star in the galaxy M-32 (a.k.a., NGC-221).  The
data will solidly define the helium shell-burning asymptotic giant branch
population for later interpretation as the theory of the AGB grows more
mature.  During this proposal, the 27 minute, five second loss of lock
described in 2.1 occurred, taking down the take data flag.  Otherwise, the
observations were completed as planned, and no further problems were
reported.

   1.34 Completed NIC/2/3 7453 (The SBF Hubble Diagram)

       The Near Infrared Camera (Camera Two and Three) was used to make
deep NICMOS observations of galactic cluster Abell-0262 to determine its
distance using the surface brightness fluctuation {SBF} method.  HST is
essential for its high spatial resolution which makes it possible to detect
and remove globular clusters and background galaxies that contaminate the
SBF measurement.  During this proposal, the 27 minute, five second loss of
lock described in 2.1 occurred, taking down the take data flag.  Otherwise,
the observations were executed as scheduled, and no further anomalies were
noted.

   1.35 Completed WF/PC-2 6703 (Weak Radio Galaxies at Z > 2: Imaging a
Unique Sample)

       The WF/PC-2 was used to make observations of the weak radio galaxy
GAL-0225+3 which is located at a distance of Z > 2.0.  Only the HST can
deliver the resolution necessary to investigate the structure of galaxies
at redshifts z > 2.  The observations were completed as scheduled, and no
anomalies were reported.

   1.36 Completed WF/PC-2 6431 (Determination of the Extragalactric
Distance Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-3319 to
be used in measuring the periods of Cepheid variable stars within this
galaxy.  This will allow for a more accurate estimate of the distances to
these galaxies through the period-luminosity relation for the Cepheid
stars.  The observations were executed as scheduled, and no anomalies were
noted.

   1.37 Completed NIC/2 7213 (High Resolution Imaging of "Warm"
Hyperluminous Infrared Galaxies)

       The Near Infrared Camera (Camera Two) was used to make high
resolution infrared images of the "warm" hyperluminous galaxy MRK463 in
order to expand our knowledge of their complicated relationship with the
QSO phenomenon.  The observations were executed as scheduled, and no
anomalies were noted.

   1.38 Completed NIC/2 7495 (Survey of Gravitational Lenses as
Cosmological Tools)

       The Near Infrared Camera (Camera Two) was used to make survey
observations of the object H1413+117 by obtaining deep, high-resolution
images in the optical and near IR in order to see if they are gravitational
lenses and could be used as a cosmological tool.  The observations were
executed as scheduled, and no anomalies were noted.

   1.39 Completed NIC/2 7420 (A Near-Infrared Search for Very Low Mass
Companions to Stars Within 10 Parsecs of the Sun)

       The Near Infrared Camera (Camera Two) was used to make searching
observations for very low mass companions to variable star HD217357.  This
star is known to be within 10 parsecs of the Sun.  The observations were
executed as scheduled, and no anomalies were noted.

   1.40 Completed NIC/1/2/3 7461 (A Search For Old Stars in IZw18)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of blue compact dwarf galaxy IZW18 as part of a search to
look for old stars.  Its heavy element abundance is the lowest ever
measured in the ionized gaseous component of a galaxy.  During this
proposal, the 15 second loss of lock described in 2.1 occurred, taking down
the take data flag.  Otherwise, the observations were completed as
scheduled, and no further anomalies were reported.

   1.41 Completed Three Sets of NIC/2 7327 (Elliptical Galaxy Evolution at
High Redshift: IR Imaging of 60 Distant Clusters)

       The Near Infrared Camera (Camera Two) was used to make infrared
observations of high redshifted elliptical galaxies in galactic cluster
MS1137.5+6.  By measuring the structural properties of high redshift
cluster elliptical galaxies, it is hoped to resolve the controversy
regarding the age and formation history of bright cluster ellipticals.  The
observations were executed as scheduled, and no anomalies were noted.

   1.42 Completed WF/PC-2 6869 (The Jet-ISM Interaction in NGC-5128)

       The WF/PC-2 was used to make observations of the interaction of the
jet from galaxy NGC-5128 and the interstellar medium.  This galaxy has many
peculiarities, one of which is a collection of blue knots and H-II regions
associated with the eastern side of the northern radio lobe.  Spectroscopic
studies suggest these objects are complexes of young stars which have been
produced under extremely unusual conditions.  The observations were
completed as scheduled, and no problems were reported.

   1.43 Completed FOC/96 6305 (Supernova Light Echoes II)

       The Faint Object Camera (F/96) was used to make observations of
super nova SN1991T in order to study its light echoes.  This is to carry
out imaging polarization observations of candidate light echoes of
historical supernovae to determine the distances to the host galaxies
geometrically.  The observations were completed as planned, and no
anomalies were reported.
