APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday November 18, 2008 (MJD 54789) ---=== OBSERVING TEAM ===--- Dan Oravetz Howard Brewington Steph Snedden (swing) ---=== OBSERVING PLAN ===--- BOSS/SEGUE until 05:54 (4.5 h), then SEGUE (6.3 h) ---=== OBSERVING SUMMARY ===--- Declared plate 3133 DONE: Imaged stripe 78 N -startLambda 157 -endLambda 176 (ramps included). Added signal to plates 3156 and 3153. ---=== OBSERVING LOG ===--- Afternoon: ---------- id3 was unresponsive when I came in. Rebooted the photo and astro crates to start fresh. Wendell worked on the ODH sensor in the upper enclosure. Norm checked to see that the LED was covered with tape. It was. No other problems noted. Spectro focus was given a small adjustment. See after the problems section for details. Night: ----- 22:50Z Doors and louvers opened, fans on 23:55Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, and checked fiducial crossings for each axis. 23:57Z Sunset 00:50Z Cart 02, plate 3133 (Segue). Field was found in bright twilight with an FK5 star. Plate was declared DONE; see below. 00:55 56448 10.0 flat 00:58 56449 2.0 arc 01:10 56450 10.0 flat 01:13 56451 2.0 arc 01:25Z Twilight 01:49 56452 1800.0 target 02:27 56453 1800.0 target 02:30 56454 10.0 flat 02:33 56455 2.0 arc 03:07 56456 1801.0 target 03:44 56457 1800.0 target 03:47 56458 10.0 flat 03:49 56459 2.0 arc MJD b1 r1 b2 r2 Texp ------------------------------------- 54774 10.4 3.7 8.7 3.9 1500.0 54774 11.2 3.7 9.9 4.0 1500.0 54774 11.9 3.7 10.6 4.5 1501.0 54776 3.9 2.2 3.6 2.4 1800.0 54776 3.6 2.2 3.7 2.9 1800.0 54776 3.3 1.9 3.5 3.0 1800.0 54776 2.5 0.9 1.7 1.1 1800.0 54788 5.8 3.2 4.7 3.3 1800.0 54788 6.8 3.4 5.8 4.2 1800.0 54789 4.8 1.9 3.9 2.6 1800.0 54789 5.9 2.1 7.6 3.2 1800.0 54789 11.6 3.9 8.6 4.5 1801.0 54789 14.0 4.2 11.4 3.9 1800.0 Total: 95.7 37.0 83.7 43.5 22502.0 Total when ALL b,r values > 2.0: 85.1 32.3 74.6 36.8 17102.0 04:05Z Mounted imager 04:19Z Stripe 78 N -startLambda 157 -endLambda 176 (ramps included); see Imaging_Details for more info. 05:45Z On-telescope bias 05:57Z Moonrise 06:00Z Dismounted imager at moonrise. 06:15Z Cart 01, plate 3156 (Segue).
