HUBBLE SPACE TELESCOPE DAILY REPORT #2036 PERIOD COVERED: 0000Z (UTC) 01/08/98 - 0000Z (UTC) 01/09/98 Daily Status Report as of 009/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed STIS/CCD 7802 (Daily Darks to Update Acquisition Bad Pixel Table) The Space Telescope Imaging Spectrograph (CCD) was used to make calibration observations to obtain daily darks to update the acquisition bad pixel table. These 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 executed as scheduled, and no anomalies were noted. 1.2 Completed NIC/2 7219 (Ultraluminous Infrared Galaxies) The Near Infrared Camera (Camera Two) was used to make observations of the ultraluminous infrared/radio galaxy 3C293. The luminous IRAS galaxies are probably powered by nuclear starbursts and/or central AGNs; many of these systems exhibit evidence of recent galactic interaction or merging. The observations were completed as planned, and no problems were reported. 1.3 Completed WF/PC-2 7619 (WF/PC-2 Cycle 7 Decontamination) The WF/PC-2 was used to conduct a Cycle 7 decontamination procedure. Ultraviolet-blocking contaminants were removed, and hot pixels were cured, by warming the CCDs to +20C for 6 hours. A variety of internal images were taken before and after the decontamination in order to verify its success and to monitor the instrument health. The procedures were conducted as scheduled, and no problems were reported. 1.4 Completed Two Sets of NIC/1/2/3 7425 (Gravitational Lensing Enhanced NICMOS Imagery of a Young, Rapidly Evolving Faint Blue Galaxy) The Near Infrared Camera (Cameras One, Two and Three) was used to make observations of the galactic cluster GAL-CLUS-0673. Previous WF/PC-2 observations of this gravitational lens system show a faint blue galaxy is multiple-imaged by a foreground rich galaxy cluster have allowed the reconstruction of the source. It displays a spectacular ring like morphology with several bright knots and a dark center that strongly suggests vigorous star formation and rapid evolution. The observations were completed as planned, and no problems were reported. 1.5 Completed FGS 6877 (Parallax of Feige-24) The Fine Guidance Sensors were used to make astrometric observations of the X-ray source and interacting binary system Feige-24 and several other reference stars. A precise parallax would increase the validity of many astrophysical investigations. The observations were executed as scheduled, and no anomalies were reported. 1.6 Completed Four Sets of NIC/2/3 7922 (New NICMOS Modified One Orbit Parallel) The Near Infrared Camera (Cameras One and Two) was used to make one orbit parallel observations. This proposal obtains "JH" imaging, and G096 and G141 spectroscopy of sky regions when another instrument is prime. STEP64 sequences are used and two dither positions are obtained for each filter. The observations were executed as scheduled, and no anomalies were noted. 1.7 Completed Three Sets of STIS/CCD 7781 (STIS Non-Scripted Parallel Archive Proposal - Full Orbit) The Space Telescope Imaging Spectrograph (CCD) was used for a non-scripted parallel archive proposal (one full orbit). The observations were executed as scheduled, and no anomalies were noted. 1.8 Completed WF/PC-2 7623 (WF/PC-2 Cycle 7 Internal Flats) The WF/PC-2 was used to make a set of internal Cycle 7 calibration flats which are designed to monitor the pixel to pixel flat field response and the visflat lamp degradation, as well as detect any possible changes due to contamination. The calibration observations were completed as planned, and no problems were reported. 1.9 Completed STIS/CCD/MA2 7347 (Direct Imaging of Betelgeuse) The Space Telescope Imaging Spectrograph (CCD and MA2) was used to make observations of the super giant star Betelgeuse (a.k.a., HD39801, BD+75D325 or Alpha Orionis). Our UV images of Alpha Orionis obtained with the FOC in 1995 {Cycle 5} are the first direct images of the surface of a star other than the Sun. The observations were completed as planned, and no anomalies were reported. 1.10 Completed Two Sets of WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental Darks PT1/3) The WF/PC-2 was used to make supplemental dark calibration images. This set of calibrations is intended to obtain three dark frames every day to provide data for monitoring and characterizing the evolution of hot pixels. The observations were executed as scheduled, and no anomalies were noted. 1.11 Completed Two Sets of 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. 1.12 Completed Two Sets of WF/PC-2 7786 (Pure Parallel Archive Survey - Continuation) The WF/PC-2 was used to make observations as part of an archival survey program in which the images were taken in parallel with the prime science observations. These WF/PC-2 parallel observations were obtained in the ultraviolet in a search for interesting objects. The observations were completed as planned, and no problems were reported. 1.13 Completed FGS 7682 (FGS-3 Blue Transfer Function Reference Search Calibration) The Fine Guidance Sensor-3 was used to make observations of candidate star HD34816 in order to perform the blue Transfer Function reference search calibration. This proposal will measure the transfer function of a number of blue candidate stars in order to verify a single star which can be used for the blue calibration of the Trans Mode. The observations were exected as scheduled, and no anomalies were reported. 1.14 Completed FGS 7677 (Monitor the Long Term Stability of FGS-3) The goal of these measurements is to monitor the internal positional stability of FGS3 by measuring many stars in the M35 check field repeatedly over a one year period. The results of these measurements are the stability characteristics of FGS3 which allow an estimate of differential corrections to OFAD and plate scale. The measurements were completed as scheduled. with no reported anomalies. 1.15 Completed Two Sets of STIS/CCD 7783 (STIS Parallel Science) The Space Telescope Imaging Spectrograph (CCD) was used to make observations taken in parallel with the prime science.
