Daily Status Report as of 285/0000Z
    1.1 Completed Three Sets of WF/PC-2 8826 (Cycle 9 Supplemental Darks pt 1)
        The WF/PC-2 was used to perform a T dark calibration program that obtains three dark frames every day in order to provide data for monitoring and characterizing the evolution of hot pixels.  There were no reported anomalies.
    1.2 Completed Five Sets of STIS/CCD 8260 (Searching for the Hydrogen Reionization Edge of the Universe at 5HST)
        The Space Telescope Imaging Spectrograph (CCD) was used to observe one of 36 parallel orbits {4–5 fields of 5–8 orbits each} to constrain the H Lyman-edge in emission that marks the transition from a neutral to a fully ionized IGM at a predicted zion~eq5–15.  This edge is due to recombination from the H Lyman series and Lyman continuum, and can be used to constrain zion, one of the most important unknown quantities in large scale structure and cosmology.  The proposal completed nominally.
    1.3 Completed Two Sets of STIS/CCD 8837 (CCD Dark Monitor-Part 1)
        The Space Telescope Imaging Spectrograph (CCD) was used to monitor the darks.  The proposal completed with no reported problems.
    1.4 Completed STIS/CCD 8238 (Collimated Jets and Low Velocity Forbidden Emission from T Tauri Stars)
        The Space Telescope Imaging Spectrograph (CCD) was used to make observations of the T-Tauri class star DF-Tauri and to study its collimated jets and low velocity forbidden emission lines.  This is a program of slitless spectroscopy to image both the low velocity component {LVC} and high velocity component of forbidden line emission in single and binary low mass stars undergoing disk accretion.  A calibration CCD flat image was also taken.  The observations were executed as scheduled, and no anomalies were noted.
    1.5 Completed Three Sets of WF/PC-2 8816 (Cycle 9 UV Earthflats)
        The WF/PC-2 was used to obtain sequences of earth streak flats to improve the quality of pipeline flat fields for the WFPC2 UV filter set and in order to monitor flat field stability.  There were no reported problems
    1.6 Completed WF/PC-2 8805 (POMS Test Proposal: WFII Parallel Archive Proposal Continuation)
        The WF/PC-2 was used to perform a generic target version of the WFPC2 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.  The proposal completed with no reported problems.
    1.7 Completed WF/PC-2 8581 (A Search For Low-Mass Companions To Ultracool Dwarfs)
        The WF/PC-2 was used to search for very low-mass {VLM} companions to a complete sample of 120 late-M and L dwarfs, drawn mainly from the 2MASS and SDSS surveys.  The primary goal is to determine the multiplicity of M < 0.1 M_odot dwarfs.  In particular, we aim to identify binary systems suitable for long-term astrometric monitoring and mass measurement, and systems with cool, sub-1000K companions.  The proposal completed with no reported problems.
    1.8 Completed Two Sets of STIS/CCD 8562 (Probing the Large Scale Structure: Cosmic Shear Observations)
        The Space Telescope Imaging Spectrograph (CCD) was used to probe the distortion of light bundles from distant galaxies, looking at the statistical properties of the intervening inhomogeneous {dark} matter distribution.  The proposal completed nominally.
    1.9 Completed STIS/CCD 8631 (Bright Quasar Close Lensing Search II)
        The Space Telescope Imaging Spectrograph (CCD) was used to expand the Cycle 8 second generation HST snapshot survey of bright quasars, optimized to find lenses with component image separations < 1".  The observations completed nominally.
    1.10 Completed WF/PC-2 8645 (A Survey of Mid-UV Morphology of Nearby Galaxies: Galaxy Structure and Faint Galaxy)
        The WF/PC-2 was used to investigate the relation between star formation and the global physical characteristics of galaxies to interpret the morphologies of distant galaxies in terms of their evolutionary status.  The observations completed nominally.
    1.11 Completed STIS/CCD 8700 (A STIS Spectroscopic Snapshot Survey of 3CR Radio Galaxies : The Nature of the Unresolved Nuclei)
        The Space Telescope Imaging Spectrograph (CCD) was used to perform STIS snapshot long-slit spectroscopy of these nuclei over 2900- 10300 AA to classify them {QSO, NLRG, BLRG, BL Lac, ldots} and establish their AGN characteristics down to the lowest nuclear luminosities, while still within powerful 3C radio galaxies.  The primary goals are : {1} to test unification schemes by identifying previously undetected signatures of low-level AGN/QSO activity in their spectra in the form of weak, broad emission lines, featureless continua, and UV excess, {2} to constrain the FR I/BL Lac connection by measuring the relative contribution of thermal {starburst}, non-thermal {optical synchrotron}, and line emission, and {3} to perform line and continuum diagnostics to determine the dominant ionization mechanisms in the circumnuclear regions {tenths of arcseconds} and the role of dust extinction in the NLRGs and BLRGs in the form of geometrically thick or thin tori and foreground dust.  The proposal completed as planned, with no reported anomalies.
    1.12 Completed WF/PC-2 8544 (POMS Test Proposal: WFII Backup Parallel Archive Proposal II)
        The WF/PC-2 was used to execute a POMS test proposal that was designed to simulate scientific plans.  No problems were encountered.
    1.13 Completed STIS/CCD 8838 (Bias Monitor – Part 1)
        The Space Telescope Imaging Spectrograph (CCD) was used to monitor the bias in the 1×1, 1×2, 2×1, and 2×2 bin settings at gain=1, and 1×1 at gain = 4, to build up high-S/N superbiases and track the evolution of hot columns.  The proposal completed nominally.
    1.14 Completed STIS/CCD 8663 (Survey of SMC Planetary Nebulae: Nebular and Stellar Evolution in a Low- Metallicity Environment)
        The Space Telescope Imaging Spectrograph (CCD) was used to survey of SMC planetary nebulae {PNe} in order to study the co-evolution of the nebulae and their central stars, in an environment that is chemically very metal poor.  We will obtain STIS imaging and medium-resolution slitless spectroscopy that will yield line fluxes and nebular morphologies in important emission lines, plus magnitudes of the central stars.  From these data we will gather a harvest of information: the nebular size, morphology, ionization structure, density, and mass; and the central star temperature, luminosity, and mass.  The proposal completed with no reported anomalies.
    1.15 Completed WF/PC-2 8059 (POMS Test Proposal: Targeted Parallel Archive Proposal)
        The WF/PC-2 was used to observe the parallel opportunities available in the neighborhood of bright galaxies are treated in a slightly different way from the normal pure parallels.  Local Group galaxies offer the opportunity fo
r a closer look at young stellar
populations.  Narrow-band images in F656N can be used both to identify young stars via their emission lines, and to map the gas distribution in star-forming regions.  The observations completed nominally.
    1.16 Completed Two Sets of STIS/MA1 8843 (Cycle 9 MAMA Dark Measurements)
        The Space Telescope Imaging Spectrograph (MA1) was used to perform the routine monitoring of the MAMA detector dark noise.  The proposal completed nominally.
    1.17 Completed Two Sets of WF/PC-2 8575 (Leo A Evidence for the Delayed Formation of Dwarfs Scenario)
        The WF/PC-2 was used to answer the question: Did all galaxies form at high redshift, or was the formation of certain galaxies delayed until recent cosmological epochs?  There were no reported problems.
