APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday June 13, 2008 (MJD 54631) ---=== OBSERVING TEAM ===--- Steph Snedden Shannon Watters ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- It was clear all night with plenty of moon. We finished plates 2911 and 2553. We heard "the" vibration while moving to inst change between plates 2911 and 2553. The alt was already at zenith but the az and rot were still in motion. Instead of using instChange after finishing cart 2553 we slewed to 121, 30, 0 first and then to 121, 90, 0. We didn't hear any vibration this time. We accumulated ~12K dust-hours. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working. Spectro focus set for ~15C. Night: ----- 02:43Z CART 7, PLATE 2911, SEGUE179.
