PERIOD COVERED:  0000Z (UTC) 11/01/01 - 0000Z (UTC) 11/02/01

Daily Status Report as of 306/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed Two Sets of WF/PC-2 8936 (Cycle 10 Supplemental Darks Pt1/3)

        The WF/PC-2 was used to perform a dark calibration program that 
obtains three dark frames every day to provide data for monitoring and 
characterizing the evolution of hot pixels.  The proposal completed with no 
reported problems.

    1.2 Completed STIS/CCD 8901 (Dark Monitor-Part 1)

        The Space Telescope Imaging Spectrograph (CCD) was used to monitor 
the darks.  There was no anomalous activity.

    1.3 Completed STIS/CCD 9110 (A Search for Kuiper Belt Object Satellites)

        The Space Telescope Imaging Spectrograph (CCD) was used to 
investigate whether the large number of collisions thought to have taken 
place in the primordial Kuiper belt suggest that many Kuiper belt objects 
{KBOs} could have suffered binary-forming collisions similar to that which 
formed the Pluto -- Charon binary.  Detection of such KBO satellites would 
allow measurement of  KBO masses, would help to understand the past 
collisional environment of the Kuiper belt, and would give a context to the 
otherwise unique-seeming formation of the Pluto -- Charon binary.  The 
proposal completed with no reported problems.

    1.4 Completed Two Sets of STIS/CCD 8903 (Bias Monitor - Part 1)

        The Space Telescope Imaging Spectrograph (CCD) was used to monitor 
the bias in the 1x1, 1x2, 2x1, and 2x2 bin settings at gain=1, and 1x1 at 
gain = 4 to build up high-S/N superbiases and track the evolution of hot 
columns.  There were no problems.

    1.5 Completed WF/PC-2 9160 (Disks and Envelopes of Nearby Nebulous 
Young Stellar Objects: A Snapshot Survey)

        The WF/PC-2 was used to perform a snapshot survey of nearby 
nebulous young stellar objects to study the detailed morphology of the 
their disks and envelopes and probe the effect of inclination on the 
infrared spectral energy distribution of disk/envelope systems.  The 
proposal completed as planned.

    1.6 Completed Two Sets of STIS/CCD 9285 (POMS Test Proposal: STIS 
Non-scripted Parallel Proposal Continuation III)

        The Space Telescope Imaging Spectrograph (CCD) was used to make low 
galactic latitude, non-scripted parallel observations as part of a POMS 
test proposal.  The observations were completed as planned, and no 
anomalies were reported.

    1.7 Completed Three Sets of WF/PC-2 8932 (Decontaminations and 
Associated Observations Pt. 1/3)

        The WF/PC-2 was used for the monthly WFPC2 decons.  Also included 
are instrument monitors tied to decons: photometric stability check, focus 
monitor, pre- and post-decon internals {bias, intflats, kspots, &and 
darks}, UV throughput check, VISFLAT sweep, and internal UV flat check.  No 
problems were reported.

    1.8 Completed WF/PC-2/STIS/CCD 9099 (High Spatial Resolution 
Spectroscopy of the Massive Globular Cluster G1)

        The WF/PC-2 and the Space Telescope Imaging Spectrograph (CCD) were 
used to obtain high spatial resolution, long-slit spectroscopy of the most 
luminous globular cluster in the Local Group, G1 in M31.  The kinematic 
structure obtained with these data will provide a stringent test of whether 
a central black hole exists, thereby determining whether globular clusters 
share the same intimate connection that normal galaxies do with their black 
holes.  No problems were reported.

    1.9 Completed Two Sets of WF/PC-2 8940 (Cycle 10 Earth Flats)

        The WF/PC-2 was used to monitor flatfield stability by obtaining 
sequences of Earth streak flats to construct high quality flat fields for 
the WF/PC-2 filter set.  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 proposal 
completed without incident.

    1.10 Completed STIS/CCD 8908 (CCD Imaging Flats C10)

        The Space Telescope Imaging Spectrograph (CCD) was used to 
investigate flat-field stability over a monthly period.  The proposal 
completed with no reported problems.

    1.11 Completed STIS/CCD/MA2 9166 (Fossil Gaseous Halos of Massive 
Galaxies at z~1)

        The Space Telescope Imaging Spectrograph (CCD and MA2) was used to 
observe host galaxies of high-redshift, powerful radio sources that are 
likely the progenitors of present-day gE and cD galaxies, and therefore 
provide important laboratories in which to investigate the formation of 
massive galaxies in the early Universe.  Many high-redshift radio galaxies 
exhibit giant, Ly-alpha halos.  Similar nebulae without associated radio 
sources have recently been discovered in a galaxy overdensity at z = 
3.09.  The LyAlpha luminosity of these halos is comparable to the total 
X-ray luminosities of low--z X--ray clusters, and may reflect the hot, 
cooling gas reservoir from which the galaxy/cluster is forming.  The 
observations completed as planned.

    1.12 Completed WF/PC-2 9244 (POMS Test Proposal: WFII Parallel Archive 
Proposal Continuation)

        The WF/PC-2 was used to perform a generic target version of the 
Archival Pure Parallel program.  The program will be used to take parallel 
images of random areas of the sky, following the recommendations of the 
Parallels Working Group.  The observations completed with no anomalous 
activity.

    1.13 Completed STIS/CCD 9088 (Next Generation Spectral Library of Stars)

        The Space Telescope Imaging Spectrograph (CCD) was used to produce 
a "Next Generation'' Spectral Library of 600 stars for use in modeling the 
integrated light of galaxies and clusters by using the low dispersion UV 
and optical gratings of STIS.  The library will be roughly equally divided 
among four metallicities, very low {Fe/H < -1.5}, low {-1.5 < Fe/H < -0.5}, 
near-solar {-0.5 < Fe/H < 0.1}, and super-solar {Fe/H > 0.1}, well-sampling 
the entire HR-diagram in each bin.  Such a library will surpass all extant 
compilations and have lasting archival value, well into the Next Generation 
Space Telescope era.  No problems occurred.

    1.14 Completed STIS/MA2 8920 (Cycle 10 MAMA Dark Measurements)

        The Space Telescope Imaging Spectrograph (MA2) was used to perform 
the routine monitoring of the MAMA detector dark noise, and is the primary 
means of checking on health of the MAMA detectors systems through frequent 
monitoring of the background count rate.  The proposal completed with no 
reported anomalous activity.

    1.15 Completed STIS/CCD 9047 (The Densely Spotted Photospheres of 
Active Cool Stars)

        The Space Telescope Imaging Spectrograph (CCD) was used to observe 
rapidly rotating main-sequence stars that are so heavily mottled by star 
spots that rotational modulation of their light may amount to 0.1 magnitude 
or more.  It is proposed to measure the packing fraction and size 
distribution of small star spots on the inner face of the G2/3V primary of 
the eclipsing binary SV Cam {= HD 44982}.  There were no reported problems.
