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 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. We left the Lindy cart in the enclosure because we forgot to shovel the snow up to the shed. We'll take care of it in the afternoon. ---=== 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.
