APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 18, 2007 (MJD 54209) ---=== OBSERVING TEAM ===--- Howard Brewington Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Night started out mostly clear with some sporadic clouds, but then starting around midnight, more clouds came in and seeing became variable. Many exposures were declared bad because not enough signal was obtained. However, we took: Six good exposures on cart 1, segue plate 2409 Two good exposures on cart 8, legacy plate 2644 Two good exposures on cart 5, legacy plate 2158 - Finished plate. One good exposure on cart 9, legacy plate 2145 Misc watcher errors in problem section. ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon checkout went smoothly. Uneventful. We delayed ventilating because the outside temperature was basically the same as inside the enclosure. 01:30Z - Started ventilation with doors and louvers open, fans on Night: ------ 02:01Z - Opened enclosure.
