PERIOD COVERED:  0000Z (UTC) 10/30/01 - 0000Z (UTC) 10/31/01

Daily Status Report as of 304/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed Four 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 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.

    1.3 Completed Two Sets of STIS/CCD 8901 (Dark Monitor-Part 1)

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

    1.4 Completed FGS/1 9089 (Parallaxes of Cataclysmic Variables: 
Understanding Their Peculiar Secondary Stars)

        Fine Guidance Sensor #1 was used to measure precise parallaxes for 
three additional CVs {WZ Sge, RU Peg, and YZ Cnc}, whose orbital periods 
span a much larger range than explored in previous observations, allowing 
examination of how the accretion luminosity and secondary star change with 
orbital period.  There were no problems.

    1.5 Completed Four Sets of STIS/CCD 9284 (POMS Test Proposal: STIS 
Non-Scripted Parallel Proposal Continuation IV)

        The Space Telescope Imaging Spectrograph (CCD) was used in the 
parallel mode to make some low galactic latitude archive observations.  The 
observations were executed as scheduled, and no anomalies were noted.

    1.6 Completed Three 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 STIS/CCD 9136 (T Tauri Star Coronagraphic Survey: A PMS 
Protoplanetary Disk Census)

      The Space Telescope Imaging Spectrograph (CCD) was used to observe 
pre-main sequence solar-mass stars, the T Tauri stars that Millimeter and 
IR studies suggest at least 50 percent have circumstellar disks similar to 
the disk from which our planetary system formed.  High spatial resolution, 
high dynamic range imaging of such systems will map the spatial 
distribution of material around the star, constraining the disk sizes and 
inclinations, and provide a first assessment of when structure in the disk, 
such as cleared central zones and annuli, which has been linked to planet 
formation, develops.  All observations completed without incident.

    1.8 Completed 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.

    1.9 Completed STIS/CCD 8905 (Read Noise Monitor)

        The Space Telescope Imaging Spectrograph (CCD) was used to measure 
the read noise of all the amplifiers {A, B, C, D} on the STIS CCD using 
pairs of bias frames.  Full frame and binned observations are made in both 
Gain 1 and Gain 4, with binning factors of 1x1, 1x2, 2x1 and 2x2.  All 
exposures are internals.  The proposal completed with no reported anomalies.

    1.10 Completed Three Sets of STIS/CCD 8907 (Spectroscopic Flats C10)

        The Space Telescope Imaging Spectrograph (CCD) was used to obtain 
CCD flats in the spectrographic mode.  There were no reported problems.

    1.11 Completed WF/PC-2/STIS/CCD 9267 (Supernova Search)

        The WF/PC-2 and the Space Telescope Imaging Spectrograph (CCD) were 
used to search for high-redshift supernovae in GO-observed fields, taking 
advantage of good first-epoch observations and of the scheduling 
opportunities available because STIS is not currently observing.  No 
anomalous activity was reported.

    1.12 Completed STIS/CCD/MA2 9048 (Boron Constraints on Slow Mixing in 
Low Mass Stars)

        The Space Telescope Imaging Spectrograph (CCD and MA2) was used to 
observe the atomic and nuclear characteristics of the light elements Li, Be 
and B, that make their photospheric abundances ideal tracers of internal 
physical processes in stars.  Both Li and Be have been heavily utilized to 
this end since their diminished abundances are a direct result of the 
extent of internal slow mixing between surface and interior layers, as has 
been shown with ground-based data.  Boron provides a fresh and special 
probe because it survives to greater depths inside stars than does Li or 
Be, and can thus uniquely reveal the depth of mixing.  It is proposed to 
observe B in stars with very large depletions of Li and Be, i.e. stars 
which have been the most seriously affected by mixing.  No problems occurred.

    1.13 Completed STIS/CCD/MA1 9064 (HI Detection of an Extra-Solar 
Planetary Atmosphere)

        The Space Telescope Imaging Spectrograph (CCD and MA1) was used to 
observe the extra-solar planet discovered around HD 209458 that is the 
unique one also detected through occultation.  During its transit, we will 
obtain spectra of the HI and DI Lyman-Alpha line at 1215 Angstrom.  No 
problems occurred.

    1.14 Completed WF/PC-2 8941 (Cycle 10 UV Earthflats)

        The WF/PC-2 was used to monitor flat field stability by obtaining 
sequences of earth streak flats to improve the quality of pipeline flat 
fields for the WFPC2 UV filter set.  The proposal had no problems.

    1.15 Completed WF/PC-2 9249 (POMS Test Proposal: WFII Backup Parallel 
Archive Proposal II)

        The WF/PC-2 was used to execute a POMS test proposal designed to 
simulate scientific plans.  The proposal completed with no reported problems.

    1.16 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.

    1.17 Completed STIS/CCD/MA1 8596 (Environmental Pollution: The Outflow 
in the Archetypal Galaxy-Quasar Pair NGC3067/3C232)

        The Space Telescope Imaging Spectrograph (CCD and MA1) was used to 
observe galactic-scale outflows that are now known to be a common 
occurrence in star-forming galaxies, in the nearby universe and at high 
redshift.  These superwinds have fundamental astrophysical implications for 
regulating star formation, determining the evolution of the host galaxies, 
disseminating the products of stellar nucleosynthesis over large volumes, 
and are probably responsible for many of the metal absorption lines seen in 
QSO spectra.  The observations completed with no reported problems.
