Daily Status Report as of 009/0000Z
    1.1 Completed STIS/MA2 8689 (UV Extinction in Dusty Ellipticals)
        The Space Telescope Imaging Spectrograph (MA2) was used to perform UV spectroscopy of bright inner parts of two dusty elliptical galaxies to study their ultraviolet extinction, in particular the 2175 Angstrom bump.  The observations completed with no anomalous activity.
    1.2 Completed Three Sets of WF/PC-2 8827 (Cycle 9 Supplemental Darks pt2/3)
        The WF/PC-2 was used to obtain three dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels.  The proposal completed nominally.
    1.3 Completed WF/PC-2 8811 (Cycle 9 Standard Darks)
        The WF/PC-2 was used to obtain 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.  Over an extended period these data will also provide a monitor of radiation damage to the CCDs.  The proposal completed with no reported problems.
    1.4 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.
    1.5 Completed Three Sets of WF/PC-2/STIS/CCD 8576 (The Star-Formation History of the Large Magellanic Cloud)
        The WF/PC-2 and the Space Telescope Imaging Spectrograph (CCD) were used to more accurately determine the star-formation rate and chemical evolution of the Large Magellanic Cloud that can give us a solid foundation for understanding the evolution of intermediate-mass galaxies and, potentially, the origin of "faint blue galaxies" commonly found in redshift surveys.  The proposal completed as planned.
    1.6 Completed WF/PC-2 8812 (Cycle 9 Internal Monitor)
        The WF/PC-2 was used to obtain routine internal monitors for WFPC2 in order to monitor the health of the cameras.  A variety of internal exposures are obtained in order to provide a monitor of the integrity of the CCD camera electronics in both bays {gain 7 and gain 15}, a test for quantum efficiency in the CCDs, and a monitor for possible buildup of contaminants on the CCD windows.  There were no reported problems.
    1.7 Completed WF/PC-2 8683 (Imaging Of Brightest Cluster Galaxies: The High End Of The Black Hole Mass Distribution)
        The WF/PC-2 was used to make kinematic black hole detections in galaxies to decide whether they indicate that the mass correlates with both optical luminosity and radio power.  The observation completed with no reported problems.
    1.8 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.
    1.9 Completed WF/PC-2 8632 (A UV Atlas of Nearby Galaxies)
        The WF/PC-2 was used to perform a snapshot survey of local galaxies at UV wavelengths with the F300W filter.  The aim of the project is to build a reference UV Atlas of normal galaxies, whose optical images are well known, with the highest possible degree of information, covering all the morphological types and luminosity classes.  The proposal completed normally.
    1.10 Completed 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.
    1.11 Completed STIS/CCD/MA1 8649 (Probing Stellar Interiors Via Convective Dredge-up in DQ White Dwarfs)
        The Space Telescope Imaging Spectrograph (CCD and MA1) was used to determine the composition and structure of white dwarf stars which contain a wealth of information about processes occurring in contemporary main sequence stars like our Sun.  The proposal completed nominally.
    2.1 Guide Star Acquisitions:
      Scheduled Acquisitions: 10
Successful: 10
  Scheduled Re-acquisitions:  4
Successful:  4
    2.2 FHST Updates:
Scheduled: 18
Successful: 18
    2.3 Operations Notes:
        The SSR EDAC error counter was cleared three times per ROP SR-1A.
        A TTR was written for SSAF and MAR dropouts that resulted in lost data for the interval 008/160022Z to 008/160101Z.
        The HST ephemeris table was uplinked at 009/0309Z as directed by ROP DF-7A.
        GSFC Internal Simulation #3 (EVA-2), for Servicing Mission 3B, will be run today, starting at 8:00 a.m.
        Continuation of normal science observations and calibrations.
