HUBBLE SPACE TELESCOPE DAILY REPORT #878 PERIOD COVERED: 0800 EST Daily Status Report as of 123/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed PC 4714 (WF/PC Cycle 2 Calibration: PC Internal Delta Flats) The Planetary Camera was used to make eight internal delta flat calibration observations. these observations will be used for the restoration of Earth flats, which were altered due to changes in quantum efficiency which occurred after decontaminations operations. All eight observations were received and displayed. They were reported to look okay. 1.2 Completed GHRS/2 3664 (Probing the Gas of Superbubble LMC2) The High Resolution Spectrograph was used to make nine spectral and wavelenght calibration image of OB class supergiant star HD269992, which is located in Superbubble #2 in the Large Magellanic Cloud. The wavecals and the target spectra were reported to look okay. 1.3 Completed GHRS/2 3943 (Local Interstellar Medium and D/H Ratio - Cycle 2) The High Resolution Spectrograph was used to make Lyman alpha emission spectral observations of the star Alpha Centauri (aka, HD128620). The goal was to observe interstellar H and D line absorption against the stellar emission features. The onboard search peakup target acquisition failed, as expected. A status buffer error message was received. The OSS uplinked a "best guess" nulling slew. The subsequent observations were executed with no problems other than a few guide star recentering events. The wave calibrations images looked okay. The target spectrum showed features, although the signal was weak (several hundred counts). 1.4 Completed Two Sets of PC 4770 (WF/PC Cycle 2 Calibration: Internal Monitor Proposal) The Planetary Camera was used to make an dark and bias calibration image to be used for routine calibration of the instrument and for data reduction purposes. Both images were received and displayed. They both were reported to look okay. 1.5 Completed FOC/96 4804 (UV Imaging of Nearby Galaxies with FOC/96) The Faint Object Camera was used to make two ultraviolet snapshot observations of nearby galaxies (UGC-5387 and UGC-6524). Both observations were received and displayed. The first image was reported to be blank. The second image had a recentering event during the exposure. It was reported to look okay. 1.6 Completed FOS/BL 4054 (Probing the Nuclear Region of Seyfert Galaxy NGC-5548) The Faint Object Spectrograph was used to make five spectral observations of the Seyfert galaxy NGC-5548 to study the time variability in its continuum, and emission lines of Helium II and Carbon IV. All five observations were received and displayed. The peakups were successful. The following spectra looked okay, with counts consistent with those from previous observations. 1.7 Completed Two Sets of WFC 4105 (HST Medium-Deep Survey: Cycle 1 High Latitude) The Wide Field Camera was used to make two high latitude medium deep sky survey images taken in parallel with the prime science observations. Both images were received and displayed in the OSS. They both were reported to be okay. 1.8 Completed FOC/96 3853 (SINS: The Supernova Intensive Study - 87A Revisited) The Faint Object Camera was used to make observations of the supernova SN1987A located in the Large Magellanic Cloud. Five Images were received and displayed. They all were reported to look okay. No anomalies were noted. 1.9 Completed Two Sets of WFC 3917 (HST Medium-Deep Survey: Cycle 2 Part 1) The wide field Camera was used to make three high Latitude medium deep sky survey (Cycle 2 Part 1) images taken in parallel with the prime science observations. All three images were reported to look okay. 1.10 Completed FOC/96 3881 (Crane, Augmentation, Galaxies & Clusters) The Faint Object Camera was used to make observations of bright nearby galaxy NGC-4649 (aka, M-60 in Virgo) to learn more about the stellar content and its nuclear structure. The observations were executed as scheduled, and no problems have been reported. 1.11 Uplinked Updated Ephemeris Tables, Per MOSES 2871 1.12 Completed PC 4712 (WF/PC Cycle 2 Calibration: Measles Monitor) The Planetary Camera was used to make three Earth flat calibration images using filter F517N, Both with and without filter F122M to monitor for the appearance and number of measles (i.e., a form of contamination). All three observations were received and displayed. They were reported to look okay. 1.13 Completed PC 2563 (SINS: The Supernova Intensive Study: Cycle 1 Observations) The Planetary Camera was used to make nine observations of the supernova SN1987A which is located in the Large Magellanic Cloud. All nine observations were received and displayed in the OSS. They all were reported to look okay. 1.14 Completed FOS/BL 3441 (Post Asymptotic Giant Branch Evolution in the Magellanic Clouds) The Faint Object Camera was used to make three observations of the planetary nebula SMC-SMP1 which is located in the Small Magellanic Cloud. The first observation executed during LOS, and there were no error messages received AOS. At least 14 seconds of recentering occurred during the conformation image. Only half of the third image, which was started during LOS, was received and displayed in real-time. The images still remain on the science tape recorder. 1.15 Completed FGS 2861 (Linking HIPPARCOS to the Extragalactic Reference Frame) FGS #3 was used to make astrometric observations of extragalactic object NEWEGOB-27 and a nearby field of standard stars. The observations were executed as scheduled, and no problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 18 Successful : 17 One failure from fine lock to coarse track 122/0532Z Scheduled Reacquisitions : 23 Successful : 23 Losses of Lock : 0 2.2 FHST Updates: Scheduled : 33 Successful : 32 FHST failure 122/0335Z, following acquisition was successful 2.3 Significant HSTARs: None 2.4 Operations Note: None 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete WFC 4105 (HST Medium-Deep Survey: Cycle 1 High Latitude) 3.2 Complete FGS 2861 (Linking HIPPARCOS to the Extragalactic Reference Frame) 3.3 Complete PC 4104 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor - Part 2) 3.4 Complete FOS/RD 4791 (Binaries in Globular Clusters (FOC 37) -- Spectroscopy) 3.5 Complete FOS/BL 3441 (Post Asymptotic Giant Branch Evolution in the Magellanic Clouds) 3.6 Uplink Updated Ephemeris Tables, Per MOSES 2871 3.7 Complete FOS/RD 4062 (Stellar and Gas dynamics in Normal Galaxies Augmentation: Cycle 2) 3.8 Complete FOC/96 3801 (Search for QSOs Suitable for Subsequent Observations of He II) 3.9 Complete FOC/96 4804 (UV Imaging of Nearby Galaxies With FOC/96) 3.10 Complete FOS/BL 4054 (Probing the Nuclear Regions of Galaxy NGC-5548) 3.11 Complete WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor) 3.12 Complete WFC 3917 (HST Medium-Deep Survey: Cycle 2 Part 1) 4.0 ANOMALY STATUS: 4.1 Significant New Anomalies: None 4.2 Significant Unresolved Anomalies: None 5.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH -END-
