HUBBLE SPACE TELESCOPE DAILY REPORT #1139 PERIOD COVERED: 0700 EST Daily Status Report as of 136/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WF/PC-2 5233 (Stellar Populations and Clusters in Elliptical Galaxies (WC08)) The WF/PC-2 was used to make deep observations of elliptical galaxy NGC-3379-PO which is located in the Coma Cluster of galaxies to study its stellar population. The observations were complete as scheduled, and no anomalies were noted. 1.2 Completed WF/PC-2 5560 (WF/PC-2 Cycle 2 Calibration: Internal Monitor. 1) The WF/PC-2 was used to make several internal bias, K-Spot, and flat calibration observations to monitor the CCD camera electronics, the optical alignment, and for contamination. The observations were executed as scheduled, and no anomalies have been noted. 1.3 Completed FOS/RD 5652 (SINS: The Supernova Intensive Study Target of Opportunity: Cycle 4 ) The Faint Object Spectrograph (Red Side) was used to make observations of supernova SN1994I and its circumstellar matter. The onboard target acquisition was successful, and the observations were executed without problems. Seven observations were received and displayed. No anomalies were noted. 1.4 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earthflats, Large Set) The WF/PC-2 was used to make a set of Earth flat calibration images using different filters in order to construct high quality flat fields of the OTA illumination pattern. A total of eight images were received and displayed. Two images were underexposed, one was saturated, and five were reported to be okay. 1.5 Completed Three Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies) The WF/PC-2 was used to make snapshot images of radio galaxies 3C208.1. 3C293.1, and 3C469.1. The first two sets of observations were received and displayed. They were reported to be okay. The third set of observations still remains on the Science Tape Recorder, and will be analyzed later. 1.6 Completed Eight Sets of WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral Galaxies) The WF/PC-2 was used to make observations of galaxies NGC-4592, NGC-4546, and 3C293.1 The observations were executed as scheduled. The first set of observations showed no target, and the other images were reported to be okay. No other anomalies were noted. 1.7 Completed WF/PC-2 5454 (Ellipticals With Kinematically Distinct Cores: Cycle 4 Medium) The WF/PC-2 was used to make observations of the small elliptical galaxy NGC-1700 which contains a massive core which is kinematically distinct from the rest of the galaxy. The observations were executed as scheduled, and no anomalies were noted. 1.8 Completed Two Sets of GHRS/1 5417 (A Search for the Physical Processes on Jupiter) The High Resolution Spectrograph (Side One) was used as part of a program to observe atomic hydrogen emission at different latitudes and longitudes on the planet Jupiter. The first Wave-Cal was reported to be okay, and the second was reported to have a very weak signal. Three Science observations were received and displayed. They were reported to be okay. 1.9 Completed FGS 5337 (Linking the HIPPARCOS to the Extragalactic Reference Frame: NEWHIP-C) The FGSs were used to make astrometric observations of NEWEGOC-50 and 620-REF to help tie the HIPPARCOS and extra-galactic reference frames together. The last seven of 11 target positions were monitored in real-time. The target was not located at position nine or position 11. The OSS reported that they suspect that the many-second multiple-event recenterings in the first few minutes of position 11's measurement may have caused the anomaly. 1.10 Completed FOC/96 5636 (FOC Onboard Bright Object Protection Test) The Faint Object Camera was used to make dark exposures to help evaluate the new bright object protection software for the FOC. Two dark images were received and displayed. They were reported to be okay. 1.11 Completed Three Sets of WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 Medium, High Galactic Latitude: CR-SPLIT) The WF/PC-2 was used in parallel with the prime science observations to make high galactic latitude observations as part of a medium-deep sky survey. The first two sets of observations contained two images each. They were reported to be okay. The third set of observations still remains of Science Tape Recorder #1, and will be analyzed later. 1.12 Completed FGS 5174 (Astrometric Companion Search: Cycle 4) FGS #3 was used to make astrometric observations of the possible binary dwarf star W-922 to look for an astrometric unseen, low-mass companion. The continuous scans executed on Fine Lock with no apparent problems. 1.13 Completed WF/PC-2 5091 (GTO High Latitude Parallel Program: Cycle 4) The WF/PC-2 was used in parallel with the prime science observations to make high galactic latitude observations greater than +/-30 degrees. Two images were received and displayed. They both were reported to look okay. 1.14 Completed FGS 5333 (Linking the HIPPARCOS to the Extragalactic Reference Frame: BR12-23: Part 2) The FGSs were used to obtain astrometric observations of star 1514-241IN whose apparent position lies near extragalactic objects. The astrometry observations were monitored whenever the telemetry was available. The Stop Flag was seen at least twice. It appears that some observations succeeded and some failed. 1.15 Completed WF/PC-2 5386 (Stellar Populations of Leo II Dwarf Spherical Galaxy) The WF/PC-2 was used to make observations of the small dwarf galaxy known as Leo II in order to construct an H-R diagram of the component stars. The observations were executed as scheduled, and no anomalies were noted. 1.16 Completed WF/PC-2 5375 (High Resolution Images of Virgo Galaxies with Kinematically Distinct Cores) The WF/PC-2 was used to make observations of galaxy NGC-3368, which is located in the Virgo Cluster. Four images were received and displayed in the OSS. They were reported to look okay. 1.17 Completed WF/PC-2 5415 (The distance to the M-96 Galaxy Group: Cycle 4 Medium) The WF/PC-2 was used to make observations of Cepheid variable stars within the galaxy UGC-5889 which itself is located in the M-96 galaxy cluster. Two observations were received and displayed. There were no reported problems. 1.18 Completed WF/PC-2 5149 (High Resolution Imaging of Circumstellar Shells Around Evolved Stars) The WF/PC-2 was used to make observations of the hot blue variable star HD94910 (aka, AG Car). Three images were received and displayed. They were reported to be excellent. More data still remains on the Science Tape Recorder, and will be analyzed later. 1.19 Completed WF/PC-2 5475 (A Snapshot survey for Blue Stragglers in Magellanic Cluster Cores) The WF/PC-2 was used to make short exposure snapshot images of the blue straggler stars located in populous cluster NGC-1850. All of the observations were executed as scheduled. The data remains on the Science Tape Recorder, and will be analyzed later. 1.20 Completed FGS 4884 (High Speed Astrometry: A Search for Planetary Companions to Low Mass Stars) The FGSs were used to make observations of Barnard's star to look for astrometric companions (i.e., a Jupiter-sized companion). The OSS was able to monitor most of the observations in real-time, and no problems were seen. 1.21 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4) The WF/PC-2 was used to make observations taken in parallel with the prime science observations. This is part of a survey to take pictures of a large number of fields within 30 degrees of the galactic plane. The observations were executed as scheduled, and no anomalies were noted. 1.22 Completed FGS 5336 (Linking the HIPPARCOS to the Extragalactic Reference Frame.) The FGS #3 was used to make astrometric observations of NEWEGOB-36. The astrometric observations occurred entirely within LOS, and could not be monitored. The data will be analyzed after the Science Tape Recorder #1 playback. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 17 Successful : 17 Scheduled Reacquisitions : 18 Successful : 18 2.2 FHST Updates: Scheduled :53 Successful :53 2.3 Significant HSTARs: None 2.4 Operations Notes: For the weekend period, each HST subsystem reported no significant operational problems. 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral Galaxies) 3.2 Complete Two Sets of GHRS/1 5417 (A Search for the Physical Processes on Jupiter) 3.3 Complete WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal Monitor: Darks) 3.4 Complete WF/PC-2 5465 (WF/PC-2 Imaging of Two Galaxies at Z=1.2) 3.5 Complete WF/PC-2 5570 (WF/PC-2 Cycle;e 4 Calibration: Earthflats, Large Set) 3.6 Complete WF/PC-2 5562 (WF/PC-2 cycle 4 Calibration: Internal Monitor 3: Darks) 3.7 Complete S/C 5582 (FOC/48 Monthly Activation (Camera Section Only): Cycle 4) 3.8 Complete WF/PC-2 5454 (Ellipticals with Kinematically Distinct Cores: Cycle 4 Medium) 3.9 Complete WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal Monitor. 1) 3.10 Complete WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs) 3.11 Complete WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies) 3.12 Complete FOC/96 5147 (High Resolution Observations of Symbiotic Variables: Cycle 4) 3.13 Complete WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4) 3.14 Complete GHRS/1 5373 (Excitation Processes for the Ultraviolet Day Glow of Jupiter: Cycle 4) 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-
