PERIOD COVERED: 0000Z (UTC) 07/11/00 – 0000Z (UTC) 07/12/00
Daily Status Report as of 194/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
1.1 Completed Four Sets of STIS/CCD 8808 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal Continuation III)
The Space Telescope Imaging Spectrograph (CCD) was used to make non-scripted, parallel observations as part of a POMS test proposal. The observations completed with no anomalous activity.
1.2 Completed Four 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 STIS/CCD 8439 (Bias Monitor-Part 2 C8)
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 with no reported problems.
1.4 Completed STIS/CCD 8870 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal Continuation IV)
The Space Telescope Imaging Spectrograph (CCD) was used to make non-scripted, parallel observations as part of a POMS test proposal. The observations completed with no anomalous activity.
1.5 Completed STIS/CCD 8437 (Dark Monitor-Part 2 C8)
The Space Telescope Imaging Spectrograph (CCD) was used to monitor the darks. The proposal completed nominally.
1.6 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.
1.7 Completed 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.
1.8 Completed STIS/CCD 8685 (Isolated Compact Stellar Systems In The Fornax Cluster)
The Space Telescope Imaging Spectrograph (CCD) was used to observe a new population of compact objects in the center of the Fornax Cluster. These objects have spectra typical of old stellar systems, but are unresolved in ground- based imaging. They are all at least 10 times more luminous than any Galactic globular clusters, but fainter than any known compact dwarf galaxies. They may be a new class of intermediate object, neither globular clusters nor dwarf galaxies but something in between. The observations completed nominally.
1.9 Completed STIS/CCD/MA1/MA2 8280 (Origins, Structure and Evolution of Magnetic Activity in the Cool Half of the H-R Diagram: A STIS Survey)
The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to make observations of star HD220657 to carry out part of a major ultraviolet spectral survey of "coronal" late-type stars. A wavelength calibration image was also taken. The observations were executed as scheduled, and no anomalies were noted.
1.10 Completed Two Sets of WF/PC-2 8459 (Decontaminations and Associated Observations Pt. 2/2)
The WF/PC-2 was used to perform the monthly decons. Also included are instrument monitors tied to decons: photometric stability check, focus monitor, pre- and post-decon internals {bias, intflats, kspots, & darks}, and UV throughput checks. The observations were completed nominally.
1.11 Completed STIS/CCD/MA2 8434 (Slitless Spectroscopy/MAMA)
The Space Telescope Imaging Spectrograph (CCD and MA2) was used to calibrate the dispersion solution and the sensitivity as a function of the target-position in the MAMA first order and prism slitless
spectroscopy. The observations completed with no reported problems.
