PERIOD COVERED: 0000Z (UTC) 07/21/00 – 0000Z (UTC) 07/24/00
Daily Status Report as of 206/0000Z
1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:
1.1 Completed Eleven 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 Three Sets of 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.
1.3 Completed Two Sets of 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.
1.4 Completed Four Sets of STIS/CCD 8437 (Dark Monitor-Part 2 C8)
The Space Telescope Imaging Spectrograph (CCD) was used to monitor the darks. The proposal completed nominally.
1.5 Completed Two Sets of 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.
1.6 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.
1.7 Completed Seven 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.
1.8 Completed STIS/CCD/MA1 8279 (Cataclysmic Variable Disk Winds: A High Time and Spectral Resolution Study of Flow Inhomogeneity)
The Space Telescope Imaging Spectrograph (CCD and MA1) was used to observe disks and disk winds that are found in many astrophysical settings. The proposal completed nominally.
1.9 Completed Three Sets of STIS/CCD/MA1 8801 (Observations Of The Hd 163296 Jet)
The Space Telescope Imaging Spectrograph (CCD and MA1) was used to obtain medium resolution long slit and echelle spectra of the jet and inner disk associated with the variable near-ZAMS Herbig Ae star HD
163296. These observations will shed light on the production and collimation mechanisms for protostellar jets, the relationship between protostellar mass loss and accretion, and the composition and structure present in the inner region of a circumstellar disk that may be actively forming planets. The observations completed nominally.
1.10 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.
1.11 Completed Six 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. As described in 2.1 and HSTAR 7742, for the final iteration of this proposal, the acquisition defaulted to fine lock backup on one FGS only, possibly affecting the observations in that iteration. Otherwise, the proposal completed with no further reported problems.
1.12 Completed WF/PC-2 8676 (Halo Microlens Source Systems and their Backgrounds and Reddening)
The WF/PC-2 was used to investigate the existence of dark objects in the Galactic halo suggested by the MACHO project while is about to release 5.7 years of LMC data revealing ~ 20 candidate microlensing events. The observer proposes to obtain medium-deep broadband images of eight of the new candidate source stars. The observations completed with no reported anomalies.
1.13 Completed STIS/CCD 7912 (STIS Parallel Archive Proposal – Nearby Galaxies – Imaging and Spectroscopy)
The Space Telescope Imaging Spectrograph (CCD) was used to make parallel observations of nearby galaxies. This survey will be useful to study the star formation histories, chemical evolution, and distances to these galaxies. These data will be placed immediately into the Hubble Data Archive. The observations were completed as scheduled, and no problems were reported.
1.14 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-1832 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.
1.15 Completed STIS/CCD 8176 (Confirmation and Characterization of Brown Dwarfs and Giant Planets from NICMOS 7226/7227)
The Space Telescope Imaging Spectrograph (CCD) was used to make confirmation and characterization observations of object HD98800. This is a continuation of NICMOS 7226/7227 using the STIS. A systematic search for giant planet and brown dwarf companions to stars in the solar neighborhood was the cornerstone of the NICMOS IDT’s Environments of Nearby Stars {EONS} program. The observations were completed as planned, and no anomalies were reported.
1.16 Completed WF/PC-2 8669 (Merger-Driven Evolution Of Galactic Nuclei: Observations Of The Toomre Sequence)
The WF/PC-2 was used to observe galaxy mergers that are believed responsible for triggering starburst and AGN activity in galaxies, and even perhaps transforming spiral galaxies into ellipticals. The proposal completed nominally.
1.17 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 igh-resolution information on their local environment. The proposal completed with no reported problems.
1.18 Complete STIS/CCD/MA1/MA2 8300 (Lagrange Testing of the Falling Evaporating Bodies Hypothesis on the Herbig star HD100546)
The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to observe several Herbig stars that exhibit spectroscopic variable features similar to those of the older, Main Sequence star, Beta Pictoris, and by analogy attributed to evaporation of cometary-like bodies falling on to the star. The presence of such around Herbig stars is an important and controversial issue regarding the evolutionary timescales of planetary systems formation. There were no reported anomalies.
1.19 Completed STIS/CCD/MA1 8662 (A Snapshot Survey of the Hot Interstellar Medium)
The Space Telescope Imaging Spectrograph (CCD And MA1) was used to obtain snapshot STIS echelle observations of key tracers of hot interstellar gas {C IV, N IV, and Si IV} for selected FUSE Team O VI survey targets with known UV fluxes. By taking advantage of the snapshot observing mode we will efficiently obtain a large number of spectra suitable for the study of the highly ionized hot component of the interstellar medium {ISM}. Our goals are to explore the physical conditions in and distribution of such gas, as well as to explore the nature of the interfaces between the hot ISM and the other interstellar gas phases. As described in 2.1 and HSTAR 7742, the acquisition for this proposal defaulted to fine lock backup on one FGS only, possibly affecting all observations. Otherwise, the observations completed with no further reported problems.
1.20 Completed WF/PC-2 8809 (Imaging the Chandra Deep Field with HST)
The WF/PC-2 was used to observe three candidate target fields from the AXAF deep field with WFPC2 in two bands. We will obtain high angular resolution images of the host galaxies of the AGNs detected in the X-rays. We will observe the target areas in three WFPC2 fields, each one of which contains a number of interesting objects that have been detected in the X-rays. The proposal completed nominally.
1.21 Completed WF/PC-2 8220 (Galaxy M/L Ratios, the Morphology-Density Relation, and Weak Lensing in the z=0.93 Cluster of 3C336)
The WF/PC-2 was used to obtain deep mosaic images for the radio selected cluster around 3C336 at z=0.93. This proposal is the last part of a program to take large HST WFPC2 mosaics of distant clusters. We augment the HST mosaics of the clusters with extensive ground-based spectroscopy and imaging from the Keck, MMT, ESO-VLT, NTT, and WHT telescopes. The observations completed, and there were no reported problems.
1.22 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.
1.23 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.
