APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday May 31, 2008 (MJD 54618) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev Shannon Watters Audrey Simmons (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We finished plate 2739 and acquired signal on another. We had to close ~08:40Z because of pollen. It's too bad because the sky transparency was great and the seeing was < 1" all night (it was a beautiful night for star gazing). We think we caught the pollen when it first started because we saw it increase dramatically after closing but could someone check the mirror anyway. We found the DIMM pointing at the nadir. When we set it up we DID "sync" it. We accumulated ~7k dust-hours while open. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during checkout. Spectro collimation set for ~16C tonight. Started ventilating at 01:15Z with the doors and louvers open, fans on. Mounted cart 2, plate 2739. Night: ------ 02:33Z CART 2, PLATE 2739, SEGUEFAINT164 Used an FK5.
