APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday May 24, 2008 (MJD 54611) ---=== OBSERVING TEAM ===--- Elena Malanushenko (observer) Dmitry Bizyaev (observer) Audrey Simmons (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clear night with good seeing. Moon after midnight. Finished plate 2908 (cart. 9). Added signal to plates 2922 (1), 2175 (3), 2724(5), and 2180 (8). We decided to unmount plate 2896 from cartridge 6. No signal was obtained with this plate. It has been expired, and its UTmax is well within the evening twilight. Arc lamps were checked every time we did calibrations. All time all lamps were on, no problems noticed. ---=== OBSERVING LOG ===--- Afternoon: ---------- Checkout went smoothly. No problems. Spectro focus set for ~6.5C. Started ventilating at 01:15Z, with door and louvers open, fans on. Night: ------ Clear sky at the sunset. 02:05Z enclosure opened. We moved pistons on both sp1,sp2 by +2000.
