Daily Status Report as of 300/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
1.1 Completed WF/PC-2 8598 (Snapshot Survey of Extended OIIl Lambda 5007Angstrom Emission in Seyfert Galaxies)
The WF/PC-2 was used for a snapshot survey of narrow band OIII Lambda 5007Angstrom images for a well defined sample of 88 Seyfert galaxies {29 Seyfert 1s and 59 Seyfert 2s}, 18 of which already have data in the archive, selected from a mostly isotropic property, the 60Mum flux. These data will be used: 1} to determine the origin of the misalignment between the accretion disk axis and the host galaxy plane axis, which can be due to mergers with other galaxies, or by the self induced radiation warping; 2} to compare the size and shape of the Narrow Line Regions (NLR) of Seyfert 1s and Seyfert 2s and to study the frequency of conically shaped NLR in Seyfert galaxies, which are usually unresolved from ground-based observations; and 3} estimate the importance of shocks to the ionization of the NLR. The observations completed with no reported problems.
1.2 Completed Four 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.
1.3 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 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.
1.5 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-0289 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.
1.6 Completed Two Sets of WF/PC-2 8601 (A Snapshot Survey of Probable Nearby Galaxies)
The WF/PC-2 was used to continue the very successful snapshot survey in order to use the high spatial resolution of HST to determine whether selected galaxies are nearby on the basis of resolution into stars, and the magnitudes and colors of the brightest stars. There were no reported problems.
1.7 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.
1.8 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 Two Sets of STIS/CCD 8653 (Collimation and Physical Conditions Within the HH 30 Protostellar Jet)
The Space Telescope Imaging Spectrograph (CCD) was used to observe the protostellar jet HH 30 through a wide slit in order to determine the distance from the star that the jet becomes collimated, and to diagnose the density, temperature, shock structure, and ionization within the collimation region. The loss-of-lock described in 2.1 and HSTAR 7926 occurred during the first iteration of this proposal, possibly affecting observations when the take data flag went down. Otherwise, there were no other reported problems.
1.10 Completed Two 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 loss-of-lock described in 2.1 and HSTAR 7926 occurred during the first iteration of this proposal, possibly affecting observations when the take data flag went down. Otherwise, the proposal completed with no further reported problems.
1.11 Completed STIS/MA2 8843 (Cycle 9 MAMA Dark Measurements)
The Space Telescope Imaging Spectrograph (MA2) was used to perform the routine monitoring of the MAMA detector dark noise. The proposal completed nominally.
1.12 Completed WF/PC-2 8716 (Search For Sub-Stellar Companions To Young Brown Dwarfs In The Chamaeleon I Dark Cloud)
The WF/PC-2 was used to observe twelve very low-mass dwarfs in the Chamaeleon I dark cloud, a site of on-going star formation, all showing H-alpha emission with spectral types from M6 to M8. We propose to observe these young, very low-mass dwarfs in order to search for close, faint companions. There were no reported problems.
2.0 FLIGHT OPERATIONS SUMMARY:
2.1 Guide Star Acquisitions:
Scheduled Acquisitions: 8
Successful: 8
Scheduled Re-acquisitions: 8
Successful: 8
There was a loss-of-lock at 299/115549Z following a successful acquisition that began at 299/080856Z and a successful re-acquisition at 299/112215Z. Lock was recovered via the new #44 commands. HSTAR 7926 was written. The proposals described in 1.9 and 1.10 were possibly affected.
2.2 FHST Updates:
Scheduled: 21
Successful: 21
2.3 Operations Notes:
The NICMOS 28V Bus Voltage in on side 1 (N28VIN1) continues to flag intermittently. The parameter is being monitored in accordance with an operation note.
A TTR was written for a command re-transmit required at 299/115945Z.
Per ROP NS-5, SI C&DH errors were reset at 299/1204Z.
The SR EDAC error counter was reset at 299/2233Z, using ROP SR-1A.
A WF/PC-2 shutter error was reported by the WF/PC-2 microprocessor at 300/0040Z.
3.0 SIGNIFICANT FORTHCOMING EVENTS:
Continuation of normal science observations and calibrations.
