APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday November 23, 2008 (MJD 54794) ---=== OBSERVING TEAM ===--- Dan Oravetz Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We had very light, scattered clouds all night which prevented us from doing any imaging. The last few hours of the night were lost due to bad seeing. We obtained good signal on the following segue plates: Cart 7, plate 3145 Cart 2, plate 3158 - possibly done Cart 6, plate 3162 Note to observers: Please do not observe cartridge 1 (plate 3156) or cartridge 2 (plate 3158) until we hear back from Connie. ---=== OBSERVING LOG ===--- Afternoon: ---------- Left spectro collimators at 5-6C. 23:03Z - Started ventilating. Mounted cart 7, segue plate 3145. Night: ------ 23:50Z - Opened enclosure to clear skies, but nearby streams of clouds are preventing us from imaging. Force filled spectrographs. Swapped out imager and spectro dewer. 00:04Z - Sunset. --**Cart 7, segue plate 3145**-- 00:25Z - goToField. Used fk5 to find field because we were in bright twilight. 00:57Z - Precals. 01:12Z - 30 min exposure. Seeing 1.8" 01:25Z - Twilight ends. 01:45Z - 30 min exposure. 02:18Z - Mid-cals. 02:25Z - 30 min exposure. 02:58Z - 30 min exposure. 03:31Z - Postcals. This plate is not yet complete.

Unfortunatly the conditions are not ideal for imaging yet. --**Cart 2, segue plate 3158**-- 03:35Z - goToField. Used fk5. 03:52Z - Precals. 03:58Z - 30 min exposure.

Temperature dropped drastically; seeing exploded; lost guide stars. We waited until the seeing dropped before starting another exposure. Seeing never got better. We called it.
