APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday June 11, 2008 (MJD 54629) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Elena Malanushenko Audrey Simmons (swing) French Leger - observations ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We have had good weather condition with Moon. Finished 4 plates 2796, 2902, 2178, and 2303, and obtained some signal on one other plate. The telescope was working very well for us last night. We only replaced FF lamp. Accumulated dust is 17K with humidity < 30%. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during checkout. Spectro collimation set for ~15-16C. 01:27Z - Started ventilating with doors and louvers open, fans on. The wind gust speed dropped to 31 mph and the dust levels dropped below 2000. Night: ------ 02:20 opened. It is clear, photometric, humidity 13%, dust 1.5K, high wind up to 27mph, T 17.4C. Cart 8 plate 2716, segue Used FK5 to find the guider stars. Focus is around 150. 02:59 test preCalibs Sop indicated that only three lamps are came on. We replaced one of FF lamps. 3:35 preCalib 3:43 science 1500 3:11 science 1500 4:40 science 1500 5:08 postCalib We still did not get nessasary (s/n) in b1 camera. Cart 9, plate 2902.
