HUBBLE SPACE TELESCOPE DAILY REPORT #816 PERIOD COVERED: 0800 EST 02/03/93 - 0800 EST 02/04/93 Daily Status Report as of 035/1200Z. 1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED: 1.1 Completed PC 4714 (WF/PC Calibration: PC Internal Delta Flats) The Planetary Camera was used to make four internal flat observations looking for changes in quantum efficiency which may have occurred during decontamination operations. All six images were reported to look okay. 1.2 Completed FOS/BL 3484 (Nuclear Regions of Seyfert Galaxy NGC-5548) The Faint Object Spectrograph (Blue Side) was used to make spectroscopic observations of Seyfert galaxy NGC-5548. The guide star acquisition was made in course track. The binary search target acquisition failed to located the target, and a status buffer error message was generated indicating the field was crowded. The science data was received. The problem was caused by the point spread function peaks being brighter than the faint limit. The following science observations had a reasonable number of counts, although they were a bit noisy. 1.3 Completed WFC/PC 4109 (Rapid Internal Monitor) Two internal flat observations were made with both the Planetary Camera and the Wide Field Camera looking for new forms of contamination (i.e., daises and measles). Both observations were reported to look okay. 1.4 Completed PC 4778 (Mass Ejection From Planetary Nebulae) The Faint Object Spectrograph was used to make spectral observations of the central star in the protoplanetary nebula EGB-6 (aka, 0950+139). The guide star acquisition was made in fine lock. The observations were received and displayed. It was reported that stellar objects were visible in the images. 1.5 Completed One Set of WFC/PC 3172 (Observations: Internal Monitor Proposal) and Initiated a Second Both the Wide Field Camera and the Planetary camera were used to take a total of five observations. These included both internal dark and bias images. They all were reported to look okay. 1.6 Completed FOC/96 3801 (QSOs Suitable for Subsequent Observations) The Faint Object Camera was used to take two images of quasars 1317-0507 and 1110+01 to measure the level of their ultraviolet flux to see if they can be used to make subsequent observations using the HRS and FOS. Both images were received and displayed in the OSS. Both images were reported to be blank. This was one of the possible results, and does not necessarily mean a problem. 1.7 Completed FOS/BL 4112 (Evolution of Lyman-Alpha and Carbon IV Absorption System) The Faint Object Spectrograph was used to take one set of rapid mode observations of quasar HS0624+690 to study its absorption line systems from Lyman alpha emission. The observation was received and displayed. The spectrum was reported to look normal. 1.8 Completed WFC 1306 (GTO Low Latitude Parallel Program) The Wide field Camera was used to take four low latitude observations taken in parallel with the prime science observations. All the observations were received and displayed. There were several bright stars, a faint fuzzy object, and a pair of very faint galaxies in these images. Two more images were monitored, but have not yet been evaluated. 1.9 Completed FOS/BL 3824 (Search for Silicon and Carbon in GP Com) The Faint Object Spectrograph was used to make far ultraviolet spectral observations looking for emission line of silicon, carbon, and nitrogen in cataclysmic variable star GP Com (aka, G61-29). The observations were executed as scheduled, and no problems were reported. 2.0 FLIGHT OPERATIONS SUMMARY: 2.1 Guide Star Acquisitions: Scheduled Acquisitions : 6 Successful : 6 Scheduled Reacquisitions : 7 Successful : 7 Losses of Lock : 0 2.2 FHST Updates: Scheduled : 13 Successful : 13 2.3 Significant HSTARs: None 2.4 Operations Note: None 3.0 ACTIVITIES SCHEDULED FOR NEXT REPORTING PERIOD: 3.1 Complete Two Sets of WFC/PC 3172 (Observations: Internal Monitor Proposal) 3.2 Complete WFC 3917 (HST Medium Deep Survey Part 1) 3.3 Complete PC 4140 (Rapid Internal Monitor Part 2) 3.4 Complete WFC 4105 (HST Medium Deep Survey, High Latitude) 3.5 Complete GHRS/2 4251 (Physical Conditions and Velocity Structure in Red Giants) 3.6 Complete GHRS/2 3614 (Boron as a Probe of Stellar Structure) 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. -END-
