APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday June 9, 2008 (MJD 54627) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Elena Malanushenko Audrey Simmons (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was photometric with variable seeing 1.2" - 1.8". We finished one segueFaint plate 2817 and got good signal on three other plates 2716, 2902, and 2318. Integrated dust is 15K with 15-40% of humidity. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems during checkout. Spectro collimation set for ~15C tonight. Mounted cart 8, plate 2716. 01:20Z - Started ventilating with doors and louvers open, fans on. Night: ------ 02:20 enclosure is off Cart 8, plate 2716 is mounted, segue FSonGTF 03:26 precCalib 03:36 science 900 b1=2.5 and b2=1.9. Decided to keep this exposure. 03:54 science 900--> 1500 04:22 science 1500 We obtained s/n = 5.1. 04:50 postCalibs Cart 6 plate 2902, segue Tcc closed itself and started again during instChange. Guider Mon did not update images when we run gcam. After stopMon, startMon, and showGuiderFrame we got error: sp1> showGuiderFrame Error: Star 6 won't fit in an 450*450 region, scaled 150 We started Mon in -simple mode and could continue to work with this plate. Found stars on GTF. 05:12 preCalibs 05:19 science 1200 05:42 science 1200 06:05 postCalibs We obtained s/n = 7.0 Cart 5 Plate 2817, segueFaint FSonGTF 06:23 preCalibs 06:30 science 1500 06:58 science 1500 07:26 postCalibs 07:33 science 1500-> 1800 08:06 science 1800 08:39 science 1500 -> 1800 09:12 postCalibs We obtained s/n=47.6 in r1 camera and more then 50 in all other cameras. We could not make another exposure or increase last esposure now. We think it is not efficient now to mount this cart one more time to get s/n 2.4. The weather conditions during the observations was photometric, no Moon, seeing variable 1.4-1.8. We declared this plate as DONE. Cart 9 plate 2318. FSonGTF. 09:28 preCalibs 09:34 science 1500 10:02 science 1500 10:30 postCalibs Obtained s/n = 12.4, and total 37.7 including last observations. endNight is finished. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7551 00:04Z 00:18Z 100 O -31.20 -27.45 39 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 53420, plate -9999 ------- 00:06 53420 0.0 bias ----- sequence 53421, plate 2318 ------- 00:11 53421 10.0 flat 00:14 53422 2.0 arc 00:18 53423 3.0 arc 00:21 53424 2.0 arc 00:36 53425 3.0 arc 00:39 53426 3.0 arc ----- sequence 53427, plate -9999 ------- 01:17 53427 0.0 bias 01:21 53428 0.0 bias ----- sequence 53428, plate 2716 ------- 02:56 53429 10.0 flat 02:59 53430 2.0 arc 03:29 53431 10.0 flat 03:31 53432 2.0 arc 03:53 53433 900.0 target 04:22 53434 1503.0 target 04:49 53435 1500.0 target 04:52 53436 10.0 flat 04:55 53437 2.0 arc ----- sequence 53438, plate 2902 ------- 05:14 53438 10.0 flat 05:17 53439 2.0 arc 05:41 53440 1200.0 target 06:04 53441 1201.0 target 06:07 53442 10.0 flat 06:10 53443 2.0 arc ----- sequence 53444, plate 2817 ------- 06:26 53444 10.0 flat 06:28 53445 2.0 arc 06:57 53446 1501.0 target 07:25 53447 1500.0 target 07:28 53448 10.0 flat 07:31 53449 2.0 arc 08:05 53450 1800.0 target 08:38 53451 1801.0 target 09:11 53452 1802.0 target 09:14 53453 10.0 flat 09:17 53454 2.0 arc ----- sequence 53455, plate 2318 ------- 09:31 53455 10.0 flat 09:33 53456 2.0 arc 10:02 53457 1501.0 target 10:30 53458 1500.0 target 10:33 53459 10.0 flat 10:35 53460 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:20Z 8 2716 10.20 -0.0007 47.48 0.0037 188.62 0.0095 1.000100 05:42Z 6 2902 -20.50 -0.0018 63.00 0.0046 162.67 0.0163 1.000150 06:35Z 5 2817 3.01 -0.0039 69.68 0.0047 182.51 0.0129 1.000310 09:47Z 9 2318 2.54 -0.0013 45.79 0.0041 182.12 0.0193 1.000410 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 03:21Z 8 2716 1.00010 -988 247 -125 10 47.5 18.0 1 229 -- 1.3" 05:42Z 6 2902 1.00015 -1481 -206 -125 -21 63.0 16.7 5 158 -- 1.5" 06:35Z 5 2817 1.00031 -3061 -1402 0 3 69.7 14.6 16 133 -- 1.6" 09:47Z 9 2318 1.00041 -4049 -2231 -75 2 45.8 14.0 12 142 -- 1.6" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:30Z 70 20 4 259 (W) 1787 - 00:02Z 73 19 12 266 (W) 1623 - 00:33Z 69 18 3 242 (WSW) 1674 - 01:03Z 67 17 9 315 (NW) 1772 - 01:34Z 66 14 5 329 (NNW) 1671 - 02:03Z 64 12 3 283 (WNW) 1624 - 02:34Z 63 13 1 321 (NW) 1788 - 03:07Z 63 9 4 260 (W) 1755 - 03:37Z 63 7 4 190 (S) 1840 - 04:08Z 63 7 6 193 (SSW) 1932 - 04:39Z 63 9 5 188 (S) 2068 - 05:09Z 64 8 7 230 (SW) 2097 - 05:41Z 61 10 3 167 (SSE) 2036 - 06:11Z 58 23 8 139 (SE) 2101 - 06:41Z 58 35 15 130 (SE) 2160 - 07:12Z 58 35 16 134 (SE) 2113 - 07:44Z 57 35 14 133 (SE) 2275 - 08:15Z 58 34 13 141 (SE) 2233 - 08:46Z 58 34 13 141 (SE) 2329 - 09:16Z 57 34 12 154 (SSE) 2300 - 09:47Z 57 34 12 152 (SSE) 2217 - 10:18Z 57 32 13 167 (SSE) 2242 - 10:48Z 57 28 12 177 (S) 2078 - ---=== TELESCOPE STATUS ===--- 01:20Z - Began ventilation.
