Daily Status Report as of 305/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
1.1 Completed STIS/CCD 8228 (The Black Hole Versus Bulge Mass Relationship in Spiral Galaxies)
The Space Telescope Imaging Spectrograph (CCD) was used to make observations of the galaxy NGC-3403 in order to study the black hole versus bulge mass relationship in spiral galaxies. A wavelength calibration image was also taken. The observations were executed as scheduled, and no anomalies were noted.
1.2 Completed Two 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.
1.3 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 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.
1.5 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.
1.6 Completed STIS/CCD 8253 (Jet Acceleration of Narrow Line Region Gas)
The Space Telescope Imaging Spectrograph (CCD) was used to make observations of the Markarian galaxy MARK1066 to study its jet acceleration of narrow line Gas regions. A wavelength calibration image was also taken. The observations were executed as scheduled, and no anomalies were noted.
1.7 Completed Four Sets of 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 Group. The proposal completed with no reported problems.
1.8 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.
1.9 Completed STIS/CCD/MA1 8103 (A Global Picture of White Dwarfs in Cataclysmic Variables)
The Space Telescope Imaging Spectrograph (CCD and MA1) was used to make ultraviolet spectrographic observations of the white dwarf star that is located in the cataclysmic variable star system known as WX/CET. The observations were executed as scheduled, and no problems were reported.
1.10 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.
1.11 Completed STIS/CCD/MA1 8304 (Stellar Winds from Central Stars of Young Planetary Nebulae)
The Space Telescope Imaging Spectrograph (CCD and MA1) was used to observe stellar winds from central stars of planetary nebulae that are responsible for driving the dynamical expansion as well as shaping the morphology of planetary nebulae. The observations completed with no reported anomalies.
1.12 Completed S/C 5582 (FOC/48 Monthly Activation (Camera Section Only): Cycle 4)
This proposal was executed as scheduled, and no anomalies were noted.
1.13 Completed FOC/96 7923 (FOC F/96 Turn-on)
The Faint Object Camera (f/96) was used to take an internal flat and a dark to ensure that the 30-day limit for the FOC is not
exceeded. The observations were executed as scheduled, and no anomalies were noted.
1.14 Completed STIS/CCD/MA1 8273 (The Oxygen Abundance in Translucent Interstellar Clouds)
The Space Telescope Imaging Telescope (CCD and MA1) was used to obtain high-resolution STIS echelle observations of the interstellar O I Lambda1356 absorption toward a sample of stars behind six translucent clouds characterized by large H I column densities and high
extinctions. Previous GHRS measurements of this weak feature in diffuse clouds have shown no evidence of density-dependent O depletion from the gas phase and indicate a total {gas + dust} interstellar O abundance that is about 2/3 of the solar value. The observations were completed nominally.
1.15 Completed WF/PC-2 8602 (A Snapshot Survey of the Sites of Recent, Nearby Supernovae)
The WF/PC-2 was used to conduct a snapshot survey in V and I of the sites of the nearby SNe, which have precisely known positions, to obtain high-resolution information on their local environment. The proposal completed with no reported problems.
1.16 Completed STIS/CCD 8851 (Sparse Field CTE test {Cycle 9})
The Space Telescope Imaging Spectrograph (CCD) was used to perform CTE measurements that are made using the "sparse field test", along both the serial and parallel axes. The proposal completed with no reported anomalies.
1.17 Completed WF/PC-2 8242 (Imaging of Dust Structures and Star Formation in the Disk-Halo Interface of Spiral Galaxies)
The WF/PC-2 was used to obtain images of five edge-on spirals to study star formation and dusty interstellar clouds in the disk-halo interface of these galaxies. The proposal completed with no reported problems.
1.18 Completed Two 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.

Scheduled Acquisitions: 8
Successful: 8
Scheduled Re-acquisitions: 6
Successful: 6
2.2 FHST Updates:
Scheduled: 17
Successful: 17
2.3 Operations Notes:
Using ROP SR-1A, the SSR EDAC error counter was cleared three times.
The NICMOS 28V bus volts IN side-1 continues to flag out-of-limits low.
Per HSTAR 7938, the WF/PC-2 shutter anomaly occurred at 304/153013Z.
A TTR was written for a required re-transmit at 304/203648Z.
Per ROP NS-5, SI C&DH errors were reset at 304/204617Z.
The SI C&DH status buffer was dumped at 304/2133Z as directed by ROP NS-3.
Using ROP DF-07A, the ephemeris table was ulinked at 305/0050Z.
As described in HSTAR 7939, there were failed FHST maps at 305/0550Z and at 305/0727Z when no stars were found in FHST-1. The HST was guiding in fine lock at the time after a normal acquisition, and attitude was not a problem.
3.0 SIGNIFICANT FORTHCOMING EVENTS:
Continuation of normal science observations and calibrations.
