APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 19, 2008 (MJD 54759) ---=== OBSERVING TEAM ===--- Dmitry Bizyaev (observer) Howard Brewington (observer) Nathan De Lee (UF, Marvels team ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The black cloth at laptop at the 2.5-meter needs to be replaced again. Added signal to Segue cart/plates: Cart 04, 3128 and Cart 03, 3144 Completed another exposure on the following MARVEL plates: cart 06, 3056 B Cart 05, 3055 A Cart 05, 3055 B Cart 09, 3060 A Cart 09, 3060 B Cart 01, 3043 preSelection Cart 09, 3060 B (twilight test) ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems with afternoon checkout. Spectro focus was checked but not adjusted; it's set for ~11 C. The collimate numbers are posted in the Problems Section.

We started with spectro because of scattered clouds. An FK5 was used to find the field in bright twilight. 01:19 55632 10.0 flat 01:22 55633 2.0 arc 01:44 Twilight ended 01:55 55634 1500.0 target 02:30 55635 1801.0 target 03:03 55636 1800.0 target 03:06 55637 10.0 flat 03:08 55638 2.0 arc MJD b1 r1 b2 r2 Texp ------------------------------------- 54737 4.7 2.8 4.1 3.7 1500.0 54737 5.3 3.5 4.8 4.2 1500.0 54737 4.8 3.3 4.3 3.8 1500.0 54747 3.5 2.8 3.3 2.7 1500.0 54747 2.7 2.1 2.5 2.4 1500.0 54759 11.1 5.7 9.8 4.8 1500.0 54759 13.2 6.9 12.5 5.8 1800.0 Total: 45.3 27.1 41.3 27.4 10800.0 03:12Z Cart 03, plate 3144 (Segue).

With respect to the new exposure times, wd did 5 twenty-second exposures, and 5 thirty-secong exposures. Some of the latter were done through holes in the clouds. 10:14 55645 10.0 flat 10:17 55646 2.0 arc 10:20 55647 21.0 target 10:23 55648 21.0 target 10:27 55649 21.0 target 10:31 55650 21.0 target 10:34 55651 20.0 target 10:38 55652 31.0 target 10:43 55653 31.0 target 10:47 55654 30.0 target 10:49 CLOUDS 11:00 55655 31.0 target 11:04 55656 31.0 target 11:12 55657 30.0 target 11:15 55658 31.0 target 11:18 55659 31.0 target 11:24 55660 31.0 target 11:28 55661 31.0 target 11:31 55662 10.0 flat 11:33 55663 2.0 arc 11:40Z Cart 09, plate 3060, field B, (MARVEL).
