HUBBLE SPACE TELESCOPE DAILY REPORT #1213 PERIOD COVERED: 0000Z Daily Status Report as of 242/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed FGS 5752 (Monitor the Long Term Stability of FGS #3: Revised) The FGS #3 will be used to make a large number of observations of stars located in open cluster M-35 (i.e., OF41-REF, OF77-REF, OF49-REF, OF23-REF, OF4-REF, OF10-REF, OF53-REF, OF36-REF, OF24-REF, OF14-REF, OF95-REF, OF84-REF, OF83-REF OF52-REF, OF54-REF, OF56-REF, OF64-REF, OF87-REF, OF80-REF, OF85-REF, OF41-REF, OF16-REF, OF40-REF, OF47-REF, and OF99-REF). This is a continuation of Proposal # 5118, looking for long term changes in the geometric distortion and plate scale. The observations were executed as scheduled, and no anomalies were noted. 1.2 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 completed as planned, and no problems were reported. 1.3 Completed FOC/96 5301 (Structure and Populations of Globular Clusters) The Faint Object Camera (f/96) was used to make observations of the large globular cluster NGC-5139 to make images of its core and two fields farther from the center. The observations were executed as scheduled, and no anomalies were noted. 1.4 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 High, High Galactic Latitude) 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 observations were completed as planned, and no problems were reported. 1.5 Completed Two Sets of WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs) The WF/PC-2 was used to make snapshot observations of the nearby active galactic nuclei of IR1305-241, IC4329A, and NGC-5135 to study the interactions between the central engine, the stars, and the interstellar matter in there AGNs. The observations were executed as scheduled, and no anomalies were noted. 1.6 Completed FOS/RD 5638 (High Resolution Observations of Nova CYG 92: Cycle 4) The Faint Object Spectrograph (Red side) will be used to make low resolution spectral observations of Nova Cygni 1992 to determine the metal abundance and physical conditions in the nova ejecta. The observations were executed as planned, and no anomalies were noted. 1.7 Completed WF/PC-2 5371 (HST Medium_ Deep Survey: Cycle 4 Medium Low Galactic Latitude) The WF/PC-2 was used in parallel with the prime science observations to make low galactic latitude deep multicolor images of objects such as galaxies, and stars in our galaxy. The observations were completed as planned, and no other problems were reported. 1.8 Completed GHRS/2 5168 (Io Proton Aurora? : Cycle 4 Medium) The High Resolution Spectrograph (Side Two) was used to make observations of Jupiter's moon Io while it is immersed in the plasma torus. The objective is to search for Lyman-Alpha emission caused by protons trapped in Jupiter's magnetosphere, and interacting with Io. The observations were executed as scheduled, and no anomalies were noted. 1.9 Completed FGS 5134 (Extragalactic Astrometry and Astrophysics: FT12-23, Part 2 of 2) The FGSs were used to make astrometric observations of five different stars (i.e., 2300-683IN, 2220-REF, 2221-REF, 2222-REF, INCA221-15) to tie the HIPPARCOS and extragalactic reference frames together. The observations were executed as scheduled, and no anomalies were noted. 1.10 Completed WF/PC-2 5571 (WF/PC-2 Cycle 4 Calibration: Earthflats, Smaller Set) The WF/PC-2 was used to make several ultraviolet and narrow-band filter Earth flat calibration observations to correct for the telescope's illumination pattern. The observations were completed as planned, and no problems were reported. 1.11 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance Scale: Cycle 4 High) The WF/PC-2 was used to make images of galaxy NGC-925 to be used in measuring the periods of Cepheid variable stars within the galaxy. The observations were completed as planned, and no anomalies were noted. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 5 Successful : 5 Scheduled Reacquisitions : 11 Successful : 11 2.2 FHST Updates: Scheduled :9 Successful :9 2.3 Significant HSTARs: None 2.4 Operations Notes: The HST observatory encountered no significant operational problems during the past 24 hours 3.0 ANOMALY STATUS: 3.1 Significant New Anomalies: None 3.2 Significant Unresolved Anomalies: None 4.0 SIGNIFICANT FORTHCOMING EVENTS: Nothing at this time. /DMH -END-
