APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday March 31, 2008 (MJD 54557) ---=== OBSERVING TEAM ===--- Observers: Howard Brewington Shannon Watters ---=== OBSERVING PLAN ===--- ---=== OBSERVING SUMMARY ===--- We finished 4 plates tonight (2780, 2949, 1831, 2177) and acquired signal on 3 more. We noticed that plate 2874 expires while it is at an alt of 42.5 degrees and still rising. It starts very low at ~32 degrees. So we suspect the window in the database may be wrong but since we had a higher priority plate available when it expired we switched to it. ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro focus was checked but not adjusted; it's set for ~8-degrees C. Space at /data/* was good; see below.
