Daily Status Report as of 252/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 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-6810 and NGC-6217.
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.

   1.2 Completed WF/PC-2 6857 (The H II/PDR Interface and Other Small Scale
Structure in H II Regions)

       The WF/PC-2 was used to make observations of the Trifid Nebula in
Sagittarius (A.K.A., M-20) in order to study the H II region/PDR interface
and other small scale structure within the nebula.  Recent work on the
structure of H II regions indicates that the interface between the hot
interior of a region and the adjacent molecular cloud may be much more
important in understanding the structure of these objects that previously
believed.  The observations were executed as scheduled, and no anomalies
were noted.

   1.3 Completed NIC/1/2/3 7726 (NICMOS One Orbit Parallel)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make a one orbit parallel calibration observations.  The observations were
executed as scheduled, and no anomalies were noted.

   1.4 Completed Three Sets of NIC/1/2/3 7688 (ACCUM Darks)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
measure dark current on individual pixels for a limited set of ACCUM
exposure times in order to conduct an internal calibration of ACCUM mode.
The observations were completed as scheduled, with no problems reported.

   1.5 Completed Two Sets of 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.

   1.6 Completed 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.

   1.7 Completed Two 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.

   1.8 Completed NIC/2 7228 (Imaging and Polarimetry of YSO'S)

       The Near-Infrared Camera (Camera Two) was used to investigate the
young stellar object (YSO) LKHA234-1 with coronagraphic imaging,
polarimetry, and line imaging.  The observations were completed as planned,
and no problems were reported.

   1.9 Completed Five Sets of WF/PC-2 7620 (WF/PC-2 CYCLE 7 Standard Darks)

       The WF/PC-2 was used to make a series of Cycle 7 standard dark
calibration images.  This calibration program obtains dark frames every
week in order to provide data for the ongoing calibration of the CCD dark
current rate, and to monitor and characterize the evolution of hot pixels.
The observations were executed as scheduled, and no anomalies were noted.

   1.10 Completed S/C 5582 (FOC/48 Monthly Activation (Camera Section
Only): Cycle 4)

        This proposal was executed as scheduled, and no anomalies were noted.

   1.11 Completed NIC/2 7237 (Nucleus and Inner Disk OF M-51)

       The Near Infrared Camera (Camera Two) was used to make observations
of the nuclear regions within the galaxy M-51 (A.K.A., The Whirlpool Galaxy
in Canus Venatici).  M-51 is the nearest grand design spiral galaxy with
strongly enhanced star formation along the spiral arms and evidence of a
central low luminosity AGN.  A dark calibration image was also taken.  The
observations were completed as scheduled, and no problems were reported.

   1.12 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.

   1.13 Completed STIS/CCD 7636 (STIS Spectroscopic CCD Flatfielding)

       The Space Telescope Imaging Spectroscope (CCD) was used to make a
CCD flat field calibration observation in the spectrographic mode.  A bias
calibration was also taken.  The observations were completed as planned,
and no anomalies were reported.

   1.14 Completed NIC/1/2/3 7608 (NICMOS Focus Monitoring)

       The Near Infrared Cameras (Cameras One, Two, and Three) was used to
determine and monitor the optimal focus and tilt settings for all three
NICMOS cameras by making observations of cluster NGC-3603.  This proposal
is built to run NIC1/2/3 sweeps on a 2-week basis.  The obserservations
completed without incident with no reported anomalies.

   1.15 Completed Three 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 observations were
completed as planned, and no problems were reported.

   1.16 Completed STIS/MA2 7644 (STIS NUV-MAMA Monitoring Flats)

       The Space Telescope Imaging Spectrograph (MA2) was used to obtain
near ultraviolet-MAMA flat-field observations for the construction of
bi-monthly delta-flats.  The observations were completed as planned, and no
problems were reported.

   1.17 Completed STIS/MA1/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.

   1.18 Completed NIC/2 7413 (The Dusty Environments of Protostars)

       The Near infrared Camera (Camera Two) was used to make observational
images of the dusty environment around protostar IRAS04489.  These
observations will address physical conditions in protostellar envelopes and
provide deeper insight into star and protoplanetary disk formation.  The
observations were completed as planned, and no problems were noted.
