APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday October 20, 2008 (MJD 54760) ---=== OBSERVING TEAM ===--- Howard Brewington (observer) Dmitry Bizyaev (observer) Nathan De Lee (Marvels team) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We got one good exposure with plate 3144 (SEGUE). Most of the night was cloudy with danger of rain, rain, lightnings, and sometimes critical humidity. Leopard on landru behaves not good. We have to swith to 256 colors mode before opening up control windows. After that, everything concerning saoimage display works very slowly, it feels like using AT286 with saoimage. It is extremely inconvenient to work like this. Howard repeated set up seven times in the evening because X11 crashed under the leopard. Then switched to tiger.

Sky is still in good conditions, but we have radar alert and clouds approaching from SW, and forecast warns about rain possibility after midnight. We continued to stay closed because of the approaching radar returns. Sky is partly cloudy. 08:30Z rain alert. Veltilation stopped. 11:05Z saerted ventilation again. Sky is mostly clear, but we have next wave of clouds approaching. 12:00Z ventilation stopped. 12:04Z endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7744 23:10Z 23:45Z 100 O 86.34 95.18 73 ignore 7745 23:55Z 00:15Z 100 O 97.67 102.81 49 ignore 7746 02:13Z 02:41Z 100 O 132.23 139.42 61 ignore 7747 05:41Z 11:23Z 100 O -175.51 -89.75 64 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 55665, plate -9999 ------- 23:29 55665 0.0 bias ----- sequence 55666, plate 3144 ------- 23:34 55666 0.0 bias 23:40 55667 10.0 flat 23:42 55668 2.0 arc 23:51 55669 3.0 arc 23:53 55670 3.0 arc ----- sequence 55671, plate 3128 ------- 00:16 55671 0.0 bias 02:40 55672 0.0 bias ----- sequence 55673, plate 3144 ------- 04:37 55673 10.0 flat 04:39 55674 2.0 arc 05:13 55675 1800.0 target 05:17 55676 10.0 flat 05:20 55677 2.0 arc 05:58 55678 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:43Z 3 3144 -0.04 -0.0006 47.46 0.0019 179.95 0.0207 1.000100 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 04:43Z 3 3144 1.00010 -986 472 100 -0 47.5 10.8 9 188 -- 1.8" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:43Z 49 40 13 144 (SE) 219 - cloudy 00:13Z 49 40 15 151 (SSE) 157 - '' 00:43Z 50 39 15 180 (S) 511 - '' 01:16Z 51 39 16 181 (S) 655 - '' 01:48Z 52 38 17 201 (SSW) 723 - '' 02:20Z 51 38 15 182 (S) 773 - '' 02:52Z 51 38 12 185 (S) 736 - '' 03:24Z 51 38 8 181 (S) 797 - partly clear 03:57Z 51 38 10 195 (SSW) 805 - partly clear 04:28Z 51 38 11 182 (S) 751 - '' 04:58Z 49 38 6 186 (S) 730 - mostly clear 05:29Z 50 37 4 216 (SW) 726 - '' 06:00Z 50 38 6 200 (SSW) 753 - '' 06:31Z 50 38 10 227 (SW) 795 - '' 07:01Z 50 39 8 214 (SW) 879 - clouds 07:32Z 50 39 12 205 (SSW) 873 - '' 08:03Z 50 38 9 207 (SSW) 828 - '' 08:34Z 49 38 9 214 (SW) 776 - '' 09:05Z 48 38 5 206 (SSW) 778 - '' 09:35Z 48 38 5 203 (SSW) 779 - '' 10:06Z 48 38 5 261 (W) 823 - '' 10:37Z 47 38 0 236 (SW) 785 - '' 11:08Z 48 38 2 251 (WSW) 782 - mostly clear 11:39Z 48 38 1 341 (NNW) 750 - cloudy ---=== TELESCOPE STATUS ===--- 02:26Z - Began ventilation.
