Daily Status Report as of 269/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three 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.  The observations were executed as scheduled, and no anomalies were
noted.

   1.2 Completed STIS/CCD 7659 (Daily Darks to Update Acquisition Bad Pixel
Table)

       The Space Telescope Imaging Spectrograph (CCD) was used to make dark
calibration images in order to update the acquisition bad 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.

   1.3 Completed Three Sets of NIC/1/2 7222 (Search for the Main Sequence
at the Galactic Center)

       The Near Infrared Camera (Cameras One and Two) was used to search
for O and B stars for the various lines of evidence that indicate that the
galactic center has formed stars within the last 10-200 million years.
This will give a better age determination for the last epoch of star
formation.  The observations were completed without incident.

   1.4 Completed Four Sets of STIS/CCD 7601 (CCD Dark and Bias Monitor)

       The Space Telescope Imaging Spectrograph (CCD) was used to conduct
bias and dark monitoring.   Also, observations were made to track the
growth of hot pixels on the CCD in general and within the various target
acquisition apertures specifically.  The observations were completed as
planned, and no anomalies were reported.

   1.5 Completed NIC/1/2/3 7714 (Observations of the Rest-Frame Optical
Morphology of a Statistically Significant Sample of Normal Galaxies at
Redshift z~3.)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the galaxy 1549+2126.  It is planned to use 30 orbits
with NICMOS to study the rest-frame optical morphology of star-forming
galaxies at redshift z~3 selected with the Lyman-limit technique.  The
observations were executed as scheduled, and no anomalies were noted.

   1.6 Completed WF/PC-2 Six Sets of 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 observations were
completed as planned, and no problems were reported.

   1.7 Completed Two Sets of STIS/CCD 7783 (STIS)

        The Space Telescope Imaging Spectrograph (CCD) was used to make
observations taken in parallel with the prime science.  The observations
were completed , and no problems were reported.

   1.8 Completed NIC/2 7330 (The Fueling of Active Nucleii: A NICMOS
Snapshot Survey)

       The Near Infrared Camera (Camera Two) was used to probe the dark
matter distribution of M31 far from the center by observing intervening
absorption from the MgII doublet (lambda 2800) in the spectrum of one
background QSO located in a geometrically optimal position.  HST
observations are required because this feature is in a wavelength range not
accessible from the ground, and the QSO magnitudes and expected strength of
absorption make IUE observations unfeasible.  The proposal completed as
expected with no anomalies.

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

       The WF/PC-2 was used to make a photometric search observations of
the nearby star ROSS154 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.

   1.10 Completed Five Sets of NIC/1/2/3 7729 (NICMOS Short One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
obtain "JHK" imaging of sky regions while another instrument was prime.
These observations were  part of the short NICMOS one-orbit parallel
program.  The observations were executed as scheduled, and no anomalies
were noted.

   1.11 Completed Two 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
were executed as scheduled, and no anomalies were noted.

   1.12 Completed WF/PC-2 6659 (A Search For Superplanets Around Weak T-
Tauri Stars)

       The WF/PC-2 was used to make observations in the 1 micron band of
the T-Tauri class star HBC630 in order to search for superplanets.  Weak
T-Tauri class stars (WTTS) are thought to have dissipated their
circumstellar disks recently, possibly by forming planetary systems.  The
observations were completed as planned, and no anomalies were reported.

   1.13 Completed STIS/CCD/MA1 7091 (STIS Pixel-To-Pixel Response Stability)

       The Space Telescope Imaging Spectrograph (CCD/MA1) was used to make
observations of standard star BD28D4211 in order to determine the
pixel-to-pixel response stability.  This is to illustrate that STIS has the
capability of achieving signal to noise ratio of 100:1 in both Band 1
{115-170 nm} and Band 2 {165-310 nm}.  The observations were completed as
scheduled, and no anomalies were noted.

   1.14 Completed WF/PC-2 7476 (Sakurai's Nova-Like Object: Real-Time
Monitoring of a Stellar Thermal Pulse)

       The WF/PC-2 was used to make images of Sakurai's nova-like object in
order to do real-time monitoring of a stellar thermal pulse.  The eruption
of Sakurai's nova-like variable in Sagittarius presents a
"once-in-a-lifetime" opportunity for real-time observations of a star
undergoing a final helium thermal pulse.  The observations were completed
as planned, and no anomalies were reported.

   1.15 Completed Three Sets of STIS/CCD 7782 (STIS Non-Scripted Parallel
Archive Proposal - Half Orbit)

       The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one-half orbit).  The observations
were executed as scheduled, and no anomalies were noted.

   1.16 Completed NIC/1/2/3 7421 (The Relation Between Quasar Luminosity
and Host Galaxy Mass)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
obtain ground-based, near-infrared imaging of nearby quasars which have
indicated a relation between the luminosity of the nucleus and the luminous
mass of the host galaxy.  The observations completed as planned, with no
reported problems.

   1.17 Completed WF/PC-2 6460 (Where are the Dozens of Predicted
Cataclysmic Variables in Globular Clusters?)

       The WF/PC-2 was used to make observations of the globular cluster
NGC-6171 in order to search for predicted cataclysmic variables.  WF/PC-2
imaging of globular cluster cores provides us with a unique opportunity to
detect erupting cataclysmic variables because they should be relatively
common in the core region.  The observations were executed as scheduled,
and no anomalies were noted.

   1.18 Completed STIS/CCD 7674 (IR Standards)

       The Space Telescope Imaging Spectrograph (CCD) was used 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.

   1.19 Completed FGS 7677 (Monitor the Long Term Stability of FGS-3)

       The goal of these measurements is to monitor the internal positional
stability of FGS3 by measuring many stars in the M35 check field repeatedly
over a one year period.  The results of these measurements are the
stability characteristics of FGS3 which allow an estimate of differential
corrections to OFAD and plate scale.  The measurements were completed as
scheduled. with no reported anomalies.

   1.20 Completed WF/PC-2 6967 (Blue Continuum Snapshots of 3CR Radio -
Continued Galaxies)

       The WF/PC-2 was used to make observations of the radio galaxy
3C152.0.  Radio galaxies are an important class of extragalactic objects:
they represent one of the most energetic astrophysical phenomena; they may
be used as probes of their environments; and they are unique probes of the
early universe.  The observations were completed as planned, and no
problems were reported.
