HUBBLE SPACE TELESCOPE DAILY REPORT #2000 PERIOD COVERED: 0000Z (UTC) 11/06/97 - 0000Z (UTC) 11/07/97 Daily Status Report as of 311/0000Z 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed Three 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. 1.2 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 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 executed as scheduled, and no anomalies were noted. 1.3 Completed NIC/2/3 7424 (NICMOS Imaging of QSO Absorption-- Selected Galaxies at z > 1) The Near-Infrared Camera (Cameras Two and Three) was used to make observations of QSO/galaxy SBS0953+53. The images will also be used to connect the absorption line properties to the galaxy morphological properties, inclination angles, and orientations in order to continue to explore the connection between the absorbing gas and the galaxies. The observations were completed as scheduled, and no anomalies were reported. 1.4 Completed Two Sets of STIS/CCD 7601 (CCD Dark and Bias Monitor) The Space Telescope Imaging Spectrograph (CCD) was used to conduct bias and dark monitoring. Also, observations were made to track the growth of hot pixels on the CCD in general and within the various target acquisition apertures specifically. The observations were completed as planned, and no anomalies were reported. 1.5 Completed WF/PC-2 7430 (Jovian Global Photometry During the Galileo Epoch) The WF/PC-2 was used to make observations of the planet Jupiter as part of the Jovian Global photometry study during the Galileo epoch. The observations are targeted to broaden the perspective of the spatially-, temporally-, and spectrally-limited sampling of Jupiter by Galileo, thus providing a strategic supplement to the atmospheric science derived from the Galileo mission. The observations were executed as scheduled, and no anomalies were noted. 1.6 Completed STIS/CCD/MA1/MA2 7788 (STIS/MAMA Image Location and Geometric Distortion) The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to make observations of NGC-6681 in order to determine the camera image location and geometric distortion. This proposal will obtain sufficient data, when combined with the SMOV data, to properly determine the distortion, plate scale, orientation and image location for each of the MAMA imaging modes. Approximately two-and-one-half hours into this three-and-one-half hour proposal, the suspend described in 2.3 occurred. No further anomalous activity was noted. 1.7 Completed Four 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. 1.8 Completed STIS/CCD/MA1/MA2 7653 (LSF Measure of the MAMA-Spectroscopic Modes) The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was to be used to make observations of HEN1357 to measure the LSF of MAMA spectroscopic modes with an external target. A wavelength calibration image was also to be taken. This proposal was not executed due to the suspend detailed in 2.3. 1.9 Completed NIC/1/2 7454 (The Stellar Content of Powerful Radio Galaxies -- A NICMOS Survey of 0.8 < z < 1.8 3CR) The near Infrared Camera (Cameras One and Two) was used to make infrared images of the powerful radio galaxy 3C239 in order to study its stellar content. The NICMOS imaging proposed here complements our ongoing program of imaging, spectroscopic and polarimetric investigation of these galaxies using HST, Keck, and many other telescopes. The observations were completed as planned, and no anomalies were reported. 1.10 Completed Two Sets of STIS/CCD 7783 (STIS Parallel Science) The Space Telescope Imaging Spectrograph (CCD) was to be used to make observations taken in parallel with the prime science. Both iterations of this proposal were not executed due to the suspend mentioned in 2.3. 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 : 19 Successful : 19 2.3 Operations Notes: In preparation for the NICMOS FSW 4.09 installation, NICMOS EDAC RAM and EEPROM memory dumps were performed at 310/1608Z. At 310/172558Z, the STIS suspended, issuing a status buffer message indicating that reported mode of STIS was invalid. At the time of the occurrence, STIS was in operate and both MAMAs were in high voltage. HSTAR 6235 was written. By 310/1934Z, per ROP NS-10, a full memory dump (of the EEPROM, the EDAC, and the CS buffer) was performed. A meeting was conducted at 310/2100Z with BASD, MOSES, STScI, and GSFC personnel to discuss STIS status and analysis plans. A touch-up meeting will be held at 311/1300Z to discuss analysis results, possible on-orbit testing, and proposed recovery plans. A follow-on meeting is planned for 311/1500Z to present the findings and the recovery plan to GSFC and other management personnel. Proposals described in 1.6, 1.8, and 1.10 were affected by this occurrence. 3.0 SIGNIFICANT FORTHCOMING EVENTS: Continuation of normal science observations and calibrations, and the recovery of STIS. /DMH
