APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday May 27, 2008 (MJD 54614) ---=== OBSERVING TEAM ===--- Steph Snedden Howard Brewington ---=== OBSERVING PLAN ===--- Avoid a pointing model! Science! ---=== OBSERVING SUMMARY ===--- West-door switch problem; see afternoon checkout. During a couple of arcs, we did a visual checks of the neon lamps; they all worked Finished plate: 2928 Added signal to plates: 2640 and 2818 The pointing model for last month seems to work okay. ---=== OBSERVING LOG ===--- Afternoon: ---------- When the west door of the 2.5-meter was opened, we discovered that it was possible by pressing the yellow button (dead-man switch) only. In other words, we did not have to press the yellow button and the open button as normal. The door opened with just the yellow button. The spectro focus was checked but not adjusted; it's set for about 10-deg C. The Collimate results are posted in the Problem Section. 01:40Z Opened doors and started fans. Night: ------- 02:10Z Sunset 02:12Z Enclosure off, topped-off spectro secondary dewars, checked top/bottom balance, did a test slew, checked fiducial crossings for each axis, and started the DIMM. 02:26Z Cart 06, plate 2928 (segFaint180). An fk5 star was used to find the field in bright twilight with spiralPattern and offsets. The magic offsets were A=-30 and D=-10. 03:25 53026 10.0 flat 03:28 53027 2.0 arc 03:41 Evening twilight 04:00 53028 1500.0 target 04:28 53029 1500.0 target 04:31 53030 10.0 flat 04:33 53031 2.0 arc (neon lamps were checked; all worked) This plate was declared DONE; see below: MJD b1 r1 b2 r2 Texp ------------------------------------------ 54612 14.5 8.3 17.8 10.7 1500.0 54612 15.5 8.6 18.7 11.1 1500.0 54612 13.8 7.7 16.3 11.4 1500.0 54612 11.6 6.4 14.0 9.1 1500.0 54612 12.2 6.7 14.4 9.0 1501.0 54614 14.7 7.3 17.4 10.3 1500.0 54614 15.3 6.8 17.0 9.4 1500.0 Total 97.6 51.8 115.6 71.0 10501.0 04:38Z Cart 09, plate 2460 (segFaint140).
