APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday May 9, 2007 (MJD 54230) ---=== OBSERVING TEAM ===--- Swing: Viktor Malanushenko Observers: Howard Brewington, Kaike Pan ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Declared the following plates done: 2641, 2653, 2666, 2146, and 2172. We had a problem with cart 04; see log. The spectro dewar will need to be changed later this morning. ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon checkout went smoothly. No problems to report. Spectro focus has been adjusted for night temperature of 5C. Cartridge 8 is mounted. We did not begin ventillating on time due to high humidity & rain. Night: ------ 01:30Z Doors and louvers opened, fans on as sky cleared. 01:48Z Sunset 02:10Z Enclosure off 02:17Z Cart 02, plate 2569 (segFaint149). An Fk5 was used to find the field in bright twilight. Seeing = 1.5" as reported by the guider. Completed three science exposures but could not declare this plate done. Total S/N^2 = 17.1 03:12 44743 10.0 flat 03:15 44744 2.0 arc 03:34 Evening twilight 03:40 44745 1202.0 target 04:03 44746 1201.0 target 04:31 44747 1500.0 target 04:34 44748 10.0 flat 04:37 44749 2.0 arc 04:40Z Cart 04, plate 2597 (chunk153). Guide stars found with goToField. There was a problem with this cart, i.e., some of the guide stars on the edge of the field were donuts. So, we decided to switch to another cart. ~25 minutes were lost to this problem. Could someone please checked the fibers on this cart? Thanks. 05:05Z Cart 06, plate 2641 (chunk153).
