The purpose of this proposal is to monitor the darks using three different MULTIACCUM sequences. As detailed in yesterday's report and in HSTAR 6407, the acquisition for the first iteration of this proposal failed and the take data flag remained down. Otherwise, the observations were executed as scheduled, and no further anomalies were noted. 1.2 Completed Two Sets of WF/PC-2 7712 (WF/PC-2 Cycle 7 Supplemental Darks pt2/3) The WF/PC-2 was used to make a series of Cycle 7 supplemental calibration darks. This dark calibration program obtains three dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels. As detailed in yesterday's report and in HSTAR 6407, the acquisition for the first iteration of this proposal failed and the take data flag remained down. Otherwise, the observations were executed as scheduled, and no further anomalies were noted. 1.3 Completed NIC/1 7821 (SINS: The Supernova Intensive Study - Cycle 7+: Scarlet SINS) The Near Infrared Camera (Camera One) was used to make observations of the super nova LMC-SN1987 which is located in the Large Magellanic Cloud. Supernovae create the chemical history of the Universe, energize the interstellar gas, and stand at the center of efforts to understand the extragalactic distance scale. The observations were completed as scheduled, and no problems were noted. 1.4 Completed STIS/CCD 7803 (Daily Darks to Update Acquisition Bad Pixel Table Part III) The Space Telescope Imaging Spectrograph (CCD) was used to make daily dark calibration updates. These daily darks are intended to identify hot pixels for update to the acquisition on-board FSW hot pixel table. Daily hot pixel lists can also be used for science data analysis. The observations were completed as planned, and no anomalies were reported. 1.5 Completed STIS/CCD 7926 (CCD Dark and Bias Monitor -- Continued) The Space Telescope Imaging Spectrograph (CCD) was used to make several dark and bias calibration observations. This is to measure CCD dark current and bias rates for the two supported amplifier settings {gain = 1 and gain = 4} in order to gather data for making superdarks and superbiases. These observations will also track the growth of hot pixels on the CCD in general and within the various target acquisition apertures specifically. The observations were executed as scheduled, and no anomalies were noted. 1.6 Completed NIC/2 7834 (A Search for Giant Planets Around Very Young Nearby Late-type Dwarfs) The Near Infrared Camera (Camera Two) was used to make observations of the very young, late-type, dwarf star HD48189 as part of a search for large planets. Very young late-type dwarfs at distances closer than 30 pc are excellent sites to provide a direct detection of extrasolar planets. The observations were executed as scheduled, and no anomalies were noted. 1.7 Completed STIS/CCD 7928 (STIS Spectroscopic CCD Flatfielding -- Continued) The Space Telescope Imaging Spectrograph (CCD) was used to make CCD flat field calibration images in the STIS spectroscopic mode. The calibrations were completed as planned, and no problems were reported. 1.8 Completed NIC/2 7233 (Dust Disks Around Main Sequence Stars) The Near Infrared Camera (Camera Two) was used to make observations of the dust disk around the main sequence star GM Aurigae. The observations were made with the coronagraph to minimize the effects of glare from the bright central star. A dark calibration image was also taken. The observations were completed as scheduled, and no anomalies were reported. 1.9 Completed Two Sets of STIS/CCD 7911 (STIS Galactic Plane Pure Parallel Program) The Space Telescope Imaging Spectrograph (CCD) was used to make low galactic latitude survey observations in parallel with the prime science observations. Short exposures with the 50CCD imaging mode will provide the wavelength zero-point calibration. These data will be placed immediately into the Hubble Data Archive. The observations were executed as scheduled, and no anomalies were noted. 1.10 Completed Five Sets of WF/PC-2 7909 (POMS Test Proposal: WF II Parallel Archive Proposal) The WF/PC-2 was used to make parallel observations as part of the POMS test proposal. This test proposal is designed to simulate scientific plans. The observations were completed as planned, and no problems were reported. 1.11 Completed NIC/2 7247 (Environments of T-Tauri Stars) The Near Infrared Camera (Camera Two) was used to make observations of the T-Tauri class star DG-Tau. T-Tauri stars are low {0.5-2 solar} mass, pre-main-sequence stars. Many may have circumstellar disks - theoretical models involving accretion disks have successfully explained some of the basic observational properties of these young objects. The observations were executed as scheduled, and no anomalies were noted. 1.12 Completed STIS/CCD 7908 (POMS Test Proposal: STIS Non-Scripted Parallel Proposal) The Space Telescope Imaging Spectrograph (CCD) was used to make calibration observations as part of the POMS Test Proposal. This was a STIS non-scripted parallel proposal. The observations were completed as planned, and no problems were reported. 1.13 Completed WF/PC-2 6855 (The Disks Around Young Stellar Objects) The WF/PC-2 was used to make observations of the disk surrounding the young stellar object XZ-Tau. Circumstellar material has been detected at 1.3 mm around about 50% of the young (T<10^6 yr) stellar objects in the Taurus-Auriga molecular cloud. The observations permit an estimate of the material's spatial extent, mass and temperature. The observations were executed as scheduled, and no anomalies were noted. 1.14 Completed NIC/1/2/3 7865 (NGC 4945: Bridging the Gap Between Starbursts and AGNs) The Near Infrared Camera (Cameras One, Two and Three) was used to make observations of nearby edge-on galaxy NGC-4945. This galaxy shows evidence for both a Seyfert nucleus and an outward propagating starburst. It is also characterized by a prominent cone--shaped cavity generated by a starburst driven superwind. The observations were completed as planned, and no problems were reported. 1.15 Completed Two Sets of 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. 1.16 Completed WF/PC-2 7625 (WF/PC-2 Cycle 7 Earth Flats) The WF/PC-2 was used to make a series of Earth flat calibration images. These flat fields will allow mapping of the OTA illumination pattern and will be used in conjunction with previous internal and external flats to generate new pipeline superflats. The observations were completed as planned, and no anomalies were reported. 1.17 Completed WF/PC-2 6776 (A Comparative HST Imaging Study of Radio Galaxies and Hosts) A clear understanding of the nature of the host galaxies of radio-quiet quasars, radio-loud quasars and radio galaxies is of central importance in any attempt to unify and relate the three main classes of powerful active galaxies. Existing HST studies of quasar hosts, whilst producing many interesting new results, have yielded surprisingly little hard information on the properties of the hosts themselves. This imaging study of radio galaxy 3C219 using the WF/PC-2 will remedy this situation by undertaking redder, line-free observations of our three matched AGN samples. The proposal completed with no reported problems. 1.18 Completed Four Sets of NIC/2/3 7907 (NICMOS Pure Parallel Winter 97-98) The Near Infrared Camera (Cameras Two and Three) was used to make pure parallel spectrographic observations of sky regions when another instrument is prime. The observations were completed as planned, and no anomalies were reported. 1.19 Completed STIS/CCD 7404 (STIS Spectroscopy of Markarian 78) The Space Telescope Imaging Spectrograph (CCD) was used to make observations of the galaxy Markarian 78 in order to study spectrographically the interaction between its jets and the interstellar medium in the central few kpc of this Seyfert class galaxy. A wavelength calibration image was also taken. The observations were completed as planned, and no anomalies were reported. 1.20 Completed WF/PC-2 6540 (Imaging Circumstellar Nebulae Around Luminous Blue Variables in the Magellanic Clouds) The WF/PC-2 was used to make observations of the curcumstellar nebula around the luminous blue variable star HD269445 which is located in one of the Magallanic Clouds. The objectives are to study the distribution of the ionized gas and dust in order to determine the morphology and physical properties of the circumstellar nebulae, by observing them in a narrow, line-free V continuum filter and in the H Alpha emission line. The observations were executed as scheduled, and no anomalies were noted. 1.21 Completed STIS/CCD/MA2 7433 (UV Spectral Dating of Galaxies) The Space Telescope Imaging Spectrograph (MA2) was used to make ultraviolet spectrographic observations of HD150177 to calculate a highly accurate library of UV stellar spectra that can be used to estimate the age and metallicity of galaxies of intermediate age {between 1 and 8 Gyrs}. The critical step in this effort is to test the model spectra against high-quality UV spectra of real stars. A wave length calibration image was also taken. The observations were executed as scheduled, and no anomalies were noted. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 10 Successful : 10 Scheduled Reacquisitions : 7 Successful : 7 2.2 FHST Updates: Scheduled : 21 Successful : 21 2.3 Operations Notes: A TTR was written to describe a variety of TDRSS scheduling errors. First, at 084/1935Z it became apparent that the wrong TDRSS was scheduled -- TDW was not in view. There was no data loss since the period was covered by an SSR record cycle. Second, there was an instance of the wrong frequency being designated. Finally, one support was over-scheduled -- TDW visibility ended at 085/0910Z but the event was scheduled until 085/0944Z. In this case lost data was recovered from the SSR. The EDAC error counter was cleared, using ROP SR-1, at 084/2003Z, 084/2017Z, and 085/0218Z. MA transponder usage was commanded at 085/0836Z per ROP IC-1. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Continuation of normal science observations and calibrations. /DMH
