APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday August 26, 2007 (MJD 54339) ---=== OBSERVING TEAM ===--- Audrey Simmons Dmitry Bizyaev ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We were able to get on sky, but high humidity kept up closed for half the night. We took exposures with cart 3 - plate 2459, cart 7 - plate 2620, and cart 9 - plate 2803. We ask that Brian Yanny look over the exposures and let us know the actual signal we got on them. We will update the plate database once we hear back from Brian. Thanks! Misc problems and watcher errors in problem section. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems. Checkout went smoothly. Set spectro collimation for 12C (details in problem section). 02:01Z - Started ventilation with doors and louvers open, fans on. We delayed opening because of nearby storms. Night: ------ 03:02Z - Opened enclosure. Cartridge 3, segue139, plate 2459 mounted. Note: This plate will be used as a moon test for Brian Yanny. 03:37Z - GSFOGTF. Started first 15 min exposure. Seeing 1.6" 03:56Z - Precals. 04:02Z - 15 min exposure. 04:21Z - Postcals. Signal will be reviewed by Brian. 04:35Z - Cart 7, segue154, plate 2620. GSFOGTF. 04:39Z - Precals. 04:47Z - 15 min exposure. Seeing 2.5" - 2.0" 05:05Z - 15 min exposure. 05:23Z - 15 min exposure. 05:41Z - 15 min exposure. 05:59Z - Precals. 06:07Z - 10 min exposure. 06:20Z - Postcals. Signal will be reviewed by Brian. 06:24Z - Closed enclosure due to high humidity. 10:00Z - Opened enclosure. Humidity went down slightly. Mounted cart 9, segue166, plate 2803. GSFOGTF. 10:17Z - Precals. 10:23Z - 10 min exposure. Seeing 1.3" 10:36Z - 10 min exposure. 10:50Z - Postcals. Signal will be reviewed by Brian. 10:56Z - Closed enclosure because of high humidity. We decided to call it a night. 11:23Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6909 00:10Z 00:32Z 100 O 46.59 52.18 51 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 46141, plate 2624 ------- 00:21 46141 10.0 flat 00:24 46142 2.0 arc 00:28 46143 2.0 arc 00:31 46144 3.0 arc 00:54 46145 2.0 arc 00:56 46146 2.0 arc ----- sequence 46147, plate -9999 ------- 01:49 46147 0.0 bias ----- sequence 46148, plate 2459 ------- 03:55 46148 901.0 target 03:58 46149 10.0 flat 04:01 46150 2.0 arc 04:20 46151 900.0 target 04:23 46152 10.0 flat 04:26 46153 2.0 arc ----- sequence 46154, plate 2620 ------- 04:42 46154 10.0 flat 04:45 46155 2.0 arc 05:05 46156 901.0 target 05:22 46157 901.0 target 05:41 46158 900.0 target 05:58 46159 900.0 target 06:02 46160 10.0 flat 06:05 46161 2.0 arc 06:19 46162 601.0 target 06:22 46163 10.0 flat 06:25 46164 2.0 arc ----- sequence 46165, plate 2803 ------- 10:19 46165 10.0 flat 10:22 46166 2.0 arc 10:36 46167 600.0 target 10:49 46168 600.0 target 10:52 46169 10.0 flat 10:55 46170 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:06Z 3 2459 -96.30 0.0006 44.72 0.0001 110.88 0.0232 1.000220 04:48Z 7 2620 113.35 0.0011 61.59 0.0024 -87.41 0.0126 1.000520 10:30Z 9 2803 274.50 -0.0004 66.96 0.0018 108.00 0.0375 1.000380 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 04:06Z 3 2459 1.00022 -2173 -710 -110 -96 44.7 13.9 17 118 - 1.6 04:48Z 7 2620 1.00052 -5135 -3212 -110 113 61.6 13.9 15 116 - 2.5 10:30Z 9 2803 1.00038 -3749 -2169 -200 275 67.0 12.2 10 147 - 1.3 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:53Z 64 44 11 107 (ESE) 518 - Cloudy 00:24Z 63 43 10 111 (ESE) 479 - " 00:55Z 61 42 10 86 (E) 471 - " 01:25Z 60 43 12 99 (E) 546 - Clear 01:58Z 59 42 12 95 (E) 553 - " 02:30Z 58 42 12 82 (E) 570 - " 03:02Z 57 43 15 95 (E) 602 - " 03:32Z 57 44 13 94 (E) 763 - " 04:04Z 57 44 17 121 (ESE) 718 - " 04:34Z 57 43 15 121 (ESE) 730 - " 05:04Z 55 45 14 119 (ESE) 8079 - " 05:35Z 55 48 13 114 (ESE) 815 - " 06:05Z 53 48 13 112 (ESE) 886 - " 06:37Z 54 49 14 121 (ESE) 845 - " 07:09Z 54 50 11 110 (ESE) 923 - " 07:41Z 53 49 7 103 (ESE) 21411 - " 08:13Z 54 50 12 130 (SE) 17751 - " 08:46Z 54 50 7 126 (SE) 16528 - " 09:18Z 54 49 10 128 (SE) 17399 - " 09:50Z 54 48 13 136 (SE) 12386 - " 10:22Z 54 48 12 143 (SE) 9052 - " 10:54Z 53 49 11 149 (SSE) 9728 - " ---=== TELESCOPE STATUS ===--- 02:02Z - Began ventilation.

All of them lasted only a minute, and then went back down to ~900 counts. Were these real, or do we need to CO2 the mirror tomorrow? Another rat in the trap on the south side of the enclosure.
