APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday December 14, 2007 (MJD 54449) ---=== OBSERVING TEAM ===--- Elena Malanushenko (day) Howard Brewington (observer) Shannon Watters (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We had high winds, then high humidity, then snow, then it was <-12C. We never opened but we did shovel some snow. We had a 3 watcher warnings for VS+ on CCD55. This warning appears when it's cold out. Each time the voltage was only out of spec by ~0.14% for a moment before it went back into spec. ---=== OBSERVING LOG ===--- Afternoon: --------- All equipment are checked and work properly. Spectro collimation set for -5C. Wind is 37 mph, more then limit. Ventilation is started at 23:20Z. Cart 1 is mounted.
