HUBBLE SPACE TELESCOPE DAILY REPORT #997 PERIOD COVERED: 0800 EST Daily Status Report as of 293/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed Two Sets of GHRS/2 5251 (WF/PC Shutter Control AP Test) The High Resolution Spectrograph was used to make observations of standard star BD+75D325 as part of a shutter control test. Version 5.2 of the NSSC-I flight software (FSW) contains change AP17, which controls the WFPC shutter, and the HRS FSW. The test was executed as expected, and it appeared to be successful. A total of nine spectral observations were monitored, and they were reported to look normal. 1.2 Completed GHRS/2 5041 (GHRS Sensitivity Monitor - Cycle 3) The High Resolution Spectrograph was used to make ultraviolet observations of standard star BD+75D325 to monitor the sensitivity of the HRS, which is expected to change slowly with time. The onboard target acquisition was successful. Both sets of observations were received and displayed in the OSS. They were reported to look normal. 1.3 Completed Two Sets of FOC/96 4445 (SINS: The Supernova Intensive Study - 87A Revisit - Cycle 3 High) The Faint Object Camera (f/96) was used to make observations of the supernova SN1987 which is located in the Large Magellanic Cloud. This is a continuation of proposal 3853. This is to obtain images of the remnant with several filters over a long period of time to obtain photometric data. A total of eleven observations were displayed. Except for one recentering event, the other observations were reported to be normal. 1.4 Completed WFC 4497 (Parallel High Resolution Imaging of Defuse Objects in Magellanic Clouds) The Wide Field Camera was used to make parallel observations of the nebulae regions inside of the Large Magellanic Cloud. This is a continuation of Proposal 3589. The OSS monitored the observations, and assessed the data quality. No anomalies were reported. 1.5 Completed FGS 4938 (Parallaxes of Hyades Cluster Members - Cycle 3 High) The Fine Guidance Sensor #3 was used to make astrometric observations of the star VA-776 which is a member of the open Hyades star cluster. These observations are intended to determine the parallax of the stars and compute the distance modulus for the cluster. This will help improve the estimates of distances to other galaxies, which are base on the distance of Cepheid variable stars. No anomalies were reported. 1.6 Completed WFC 4848 (GTO Low Latitude Parallel Program _ Cycle 3 High) The Wide Field Camera was used to make two high latitude medium-deep sky survey observations taken in parallel with the prime science observations. Both observations were received and displayed. They were reported to look okay. 1.7 Completed PC 5014 (WF/PC Cycle 3 Calibration: PC Flats Narrow. 2) The Planetary Camera was used to make standard Earth calibrations images for flat fielding of PC observations. Medium and narrow filters were used, with and without neutral density filters. The observations were executed as scheduled, and no problems were reported. 1.8 Completed PC 4308 (Snapshot Survey for Companions to Planetary Nebula nuclei - Cycle 3 High) The Planetary Camera was used to make an observation of the central region of planetary nebula ABELL21. It is possible that the central star in a double star. The observations was received and displayed in the OSS, the data was reported to be normal. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 7 Successful : 7 Scheduled Reacquisitions : 6 Successful : 6 2.2 FHST Updates: Scheduled : 8 Successful : 8 2.3 Significant HSTARs: None 2.4 Operations Note: Internal Simulation Type 10 (EVA#4) successfully completed yesterday, Tuesday Oct. 19,1993. The simulation lasted from 8AM until 8PM. All of the simulation objective were met. 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete PC 4904 (The Nuclei of Nearby S0 and Spiral Galaxies - IIIA Snapshot Image) 3.2 Complete PC 4308 (Snapshot Survey for Companions to Planetary Nebula - Cycle 3 High) 3.3 Complete HSP/UV2 5070 (Optical and Ultraviolet Observations of Radio Galaxies - Cycle 2 High) 3.4 Complete WFC 3589 (Parallel High Resolution Imaging of Defuse Objects in the Magellanic Clouds) 3.5 Complete Two sets of WFC/PC 5026 (WF/PC Cycle 3 Calibration: Rapid Internal Monitor) 3.6 Uplink Updated Ephemeris Tables, Per MOSES 2871 3.7 Complete PC 4903 (The Nuclei of Nearby S0 and Spiral Galaxies -II A PC Snapshot Imaging) 3.8 Complete PC 4929 (WF/PC Cycle 2 - Improved Dark Calibration) 3.9 Complete FOS/BL 5255 (Multiwavelength Observations of the Flares and Oscillations of AE AQR) 3.10 Complete WFC 4381 (HST Medium - Deep Survey - Cycle 3) 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-
