HUBBLE SPACE TELESCOPE DAILY REPORT #1107 PERIOD COVERED: 0700 EST Daily Status Report as of 090/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed Two Sets of WF/PC-2/FOS/RD 5624 (Cycle 4 DD HST Observations of Comet Shoemaker-Levy (1993E) for March) The WF/PC-2 and the Faint Object Spectrograph were used to make observations of Comet Shoemaker-Levy (1993E). The main purpose of these observations is to refine the size of the various nuclei that make up this comet. Eight observations were monitored by the OSS. The first four observations were reported to look fine. The next four had overlight sums which were lower than expected. There was some recentering events during the fifth observation. Analysis is pending receipt of the science tape recorder dump. 1.2 Completed Two Sets of 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 sixteen observations were executed as scheduled. Three observations were received and displayed. All three observations were reported to be saturated. All of the other observations still remain on the science tape recorder, and will be analyzed later. 1.3 Completed WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies) The WF/PC-2 was used to make snapshot images of radio galaxy 3C84 as part of a continuum survey and to study the galaxy's morphology. A total of four observations were executed. The first observation was monitored by the OSS, but the next three occurred during LOS. The recentering counter indicated that no recenterings occurred during this period. Complete analysis is pending receipt of the science tape recorder dump. 1.4 Completed WF/PC-2 5324 (Globular Cluster Core Imaging) The WF/PC-2 was used to make images of the central region of globular cluster NGC-7099 (aka, M-30). Five observations were executed during LOS, and were not monitored. Analysis is pending receipt of the science tape recorder dump. 1.5 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. This is to help determine the distance to this galactic group, and to improve the determination of the Hubble constant. The observations were executed as scheduled, and no anomalies were noted. 1.6 Completed WF/PC-2 5109 (A Deep Survey at High Galactic Latitude (WC06): Cycle 4) The WF/PC-2 was used to make long exposures of a high galactic latitude field to learn more about the number and morphology of distant galaxies and the luminosity function of stars in our galaxy. The observations were monitored by the OSS, and the data quality was assessed. No anomalies were noted. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 8 Successful : 8 Scheduled Reacquisitions : 6 Successful : 6 2.2 FHST Updates: Scheduled :18 Successful :18 2.3 Significant HSTARs: None 2.4 Operations Notes: All HST subsystems have operated nominally during the past operational day. 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete FOS/RD/BL 5626 (SMOV FOS Plate Scale (Revisited - Replaces 5617)) 3.2 Complete WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4 Medium, High Galactic Latitude) 3.3 Complete WF/PC-2 5612 (SMOV WF/PC-2 Decontamination) 3.4 Complete FGS 5338 (Linking the HIPPARCOS to the Extragalactic Reference Frame, NEWHIP-D) 3.5 Complete WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 Medium, High Galactic Latitude - CR-SPLIT) 3.6 Complete WF/PC-2 5109 (A Deep Survey at High Galactic Latitude (WC06): 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.
