HUBBLE SPACE TELESCOPE DAILY REPORT #918 PERIOD COVERED: 0800 EST Daily Status Report as of 180/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed WFC 4750 (WFC Observations of NGC-4319 - Markarian 205: High Resolution Morphology) The Wide Field Camera was used to make four images of the pair of interacting galaxies NGC-4319 and Mark 205. NGC-4319 has a redshift of 1700 km/sec, and Mark 205 has a redshift of 21000 km/sec. The observations were taken slightly offset from each other. All four images were reported to look good. 1.2 Completed FOC/96 3792 (UV Morphology of Starbursts in Interacting Galaxies) The Faint Object Camera was used to make four ultraviolet imaging observations of the colliding galaxy system NGC-3690 and IC694 to study the the morphology of the starbursting regions within these two galaxies. All four observations were received and displayed in the OSS. They were all reported to be okay. 1.3 Completed WFC 4381 (HST Medium - Deep Survey, Cycle 3) The Wide Field Camera was used to make one medium-deep high latitude sky survey observation taken in parallel with the prime science observations. The observation was executed as scheduled, and no problems were reported. 1.4 Completed Two Sets of WFC 4713 (WF/PC Cycle 2 Calibration: WFC Internal Delta Flats) The Wide Field Camera was used to make a total of six internal flat calibrations images. All six images were reported to be normal. 1.5 Completed PC 4140 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor - Part 2) The WFPC was used to make two internal flat calibrations images to check for new forms of contamination (i.e., Daises and measles), and to check for the possible return of quantum efficiency hysteresis. The observations completed as scheduled, and both images were reported to look okay. 1.6 Completed FOC/96 4714 (WF/PC Cycle 2 Calibration: PC Internal Delta Flats) The Faint Object Camera was used to make one internal flat calibration image which will be used for the restoration of Earth flat images, which were altered due to changes in quantum efficiency which occurred after decontamination operations. The observations was received and displayed in the OSS. It was reported to look okay. 1.7 Completed FOC/96 4846 (High Resolution Observations of Cataclysmic Variables: Cycle 3 High) The Faint Object Camera was used to make two images of the cataclysmic variable star K648 which is suspected to have a complex region of nebulosity surrounding it. Both observations were received and displayed. They both were reported to look okay. 1.8 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. 1.9 Uplinked Updated Ephemeris Tables, Per MOSES 2871 1.10 Completed Two Sets of PC 3603 (Snapshot of Protoplanetary Nebulae) The Planetary Camera was used to make a snapshot image of the protoplanetary system HD1967 to study its current morphology. One observation was received and displayed. The image was reported to be okay. 1.11 Completed WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor) Rapid Internal Monitoring observations were made with both the Wide Field Camera and the Planetary Camera using filter F555W to look for new forms of contamination (i.e. daises and measles), and the possible return of quantum efficiency hysteresis. The observations were monitored in the OSS, and the data quality was assessed. The images were reported to look okay. 1.12 Completed GHRS/2 4580 (High Resolution Observations of the Jovian UV Aurora _ Cycle 3 Med) The High Resolution spectrograph was used to make kinetic temperature measurements of the Jovian auroral regions, to better understand Jupiter's upper atmosphere. The observations were of the ultraviolet Lyman and Werner bands in the 1586 to 1620 A0 region. An onboard acquisition was performed on the Moon Io , and then the telescope was offset to Jupiter's auroral region. The observations were executed as scheduled, and no problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 7 Successful : 7 Scheduled Reacquisitions : 5 Successful : 5 Losses of Lock : 0 2.2 FHST Updates: Scheduled : 11 Successful : 12 FHST update 1&2 failed at 180/0611Z to perform a full-axis maneuver prior to a guide star acq. at 180/0639Z. Attitude does no appear to be the problem. 2.3 Significant HSTARs: None 2.4 Operations Note: None 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete Two Sets of PC 4714 (WF/PC cycle 2 Calibration: PC Internal Delta Flats) 3.2 Complete FOC/96 4845 (Study of Optical Emission Associated With Radio Jets and Hot Spots) 3.3 Complete WFC 4849 (GTO High Latitude Parallel Program Cycle 3 High) 3.4 Complete PC 4809 (Cycle 2: WF/PC PSF Calibration Proposal) 3.5 Complete FOC/96 4804 (UV Imaging of Nearby Galaxies with FOC/96) 3.6 Complete WFC 4277 (Calibration of Nearby Galaxies Type IA Supernovae as Standard Candles) 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-
