APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday November 2, 2007 (MJD 54407) ---=== OBSERVING TEAM ===--- Dan Oravetz (swing) Viktor Malanushenko (observer) Kaike Pan (observer) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Please clean the mirror, we had integrated dust count over 20k hours under humidity at ~ 55%. We imaged 82 S from 113 to -157 (included ramps) under mostly clear sky but bad seeing (bwteen 2.0" to 5", most of time it was worse than 2.5"). Rick K.: Cloud you please give us a feedback on whether tonight's data is any useful? If not, we may choose to close under simlar conditions (bad seeing, worse than 3.0", and high dust count) in the future. Thanks! The last 4 hours was lost to a combination of high dust, 50+ % humidity, and bad seeing. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working properly. Ran 'byebye' on 54397, 54399, and 54400, which only cleared about 10G on /data partition. 54398 was a non-existent directory, so I could not run 'byebye' on it. As of 22:25Z there are 42G available on /data and 607G available on /files. Spectro focus set for ~5C. 23:15Z - Began ventilation. Doors and louvers opened, fans on. Night: ------ 00:05Z mount imager and closed doors for on-telescope bias run. 00:20Z run # 7123, on-telescope bias. 00:45Z enclosure off. 01:22Z run # 7124, 82 S. ramp started at 01:32Z, at frame # 19, lambda 113. science started at 01:39Z, frame # 32, lambda 115. In focus at frame # 35. Skippy is happy from the beginning. Seeing was variable and bad: 1.7" to 4.5". 07:24Z, we decided to endDrift at frame 610, lambda -157 due to a combination of high dust (we reached an integrated dust count of 20K hours), relative high humidity 56%, and bad seeing (varies between 2.5" to 4.5"). 11:40Z seeing never improve (still at about 3.0 to 4.5"), and dust count keep 3 K plus. We never re-open. 11:50Z endNight finished. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7122 22:09Z 22:28Z 100 O 83.13 87.91 41 ignore 7123 00:25Z 00:42Z 100 O 117.36 121.56 42 bias 7124 01:23Z 07:24Z 82 S 111.30 -158.18 618 science ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 7124 15 4 28 -10.300 0.332 5.400 0.221 -0.00409 215 52 7124 84 4 110 -10.000 0.189 7.700 0.157 -0.00361 215 52 7124 136 4 36 -9.600 0.242 8.700 0.139 -0.00377 215 52 7124 189 4 71 -9.100 0.172 9.400 0.238 -0.00247 215 52 7124 239 4 34 -8.500 0.189 9.800 0.162 -0.00321 215 52 7124 293 4 2 -9.000 0.006 10.700 0.085 -0.00421 215 52 7124 362 4 7 -8.600 0.115 11.800 0.118 -0.00343 215 52 7124 414 4 40 -7.000 0.203 12.300 0.151 -0.00278 215 52 7124 464 4 7 -6.600 0.098 12.700 0.105 -0.00264 215 52 7124 517 4 46 -5.800 0.163 12.400 0.161 -0.00299 215 52 7124 569 4 24 -5.400 0.171 12.100 0.135 -0.00283 215 52 ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ 7124 25 1 52 325 69 -2.758 0.197 0.384 0.279 -0.00129 7124 25 1 52 325 54 -2.283 0.214 0.566 0.244 -0.00190 7124 25 1 52 325 73 -1.705 0.226 1.033 0.269 -0.00347 7124 25 1 52 325 76 -1.296 0.198 1.118 0.249 -0.00376 7124 25 1 52 325 62 -1.024 0.195 1.263 0.322 -0.00425 7124 43 1 52 325 15 -2.666 0.246 1.378 0.338 -0.00463 7124 43 1 52 325 39 -2.226 0.363 1.707 0.393 -0.00574 7124 43 1 52 325 40 -1.718 0.328 1.881 0.379 -0.00632 7124 43 1 52 325 41 -1.373 0.335 1.854 0.359 -0.00624 7124 43 1 52 325 30 -1.028 0.353 1.939 0.364 -0.00652 7124 95 1 52 325 3 -3.648 0.049 0.825 0.438 -0.00277 7124 95 1 52 325 3 -3.235 0.107 1.012 0.241 -0.00340 7124 164 1 52 325 3 -2.056 0.118 0.465 0.298 -0.00156 7124 164 1 52 325 6 -1.581 0.366 0.823 0.679 -0.00277 7124 164 1 52 325 10 -1.020 0.476 0.805 0.451 -0.00270 7124 164 1 52 325 7 -0.358 0.191 1.011 0.331 -0.00340 7124 164 1 52 325 9 -0.221 0.183 0.679 0.521 -0.00228 7124 198 1 52 325 5 -1.362 0.200 0.048 0.208 -0.00016 7124 528 1 52 325 4 -1.664 0.212 -0.258 0.285 0.00087 7124 528 1 52 325 5 -1.134 0.169 0.120 0.100 -0.00040 7124 528 1 52 325 3 -0.711 0.437 0.077 0.283 -0.00026 7124 528 1 52 325 5 -0.787 0.631 -0.171 0.604 0.00057 7124 528 1 52 325 5 -0.202 0.522 -0.390 0.708 0.00131 7124 544 1 52 325 4 -1.139 0.084 -0.611 0.640 0.00205 7124 544 1 52 325 8 -0.639 0.206 -0.562 0.254 0.00189 7124 544 1 52 325 4 -0.111 0.170 -0.664 0.047 0.00223 7124 544 1 52 325 3 0.309 0.172 0.039 0.434 -0.00013 7124 599 1 52 325 8 -1.786 0.330 -1.026 0.365 0.00345 ---=== 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 47115, plate -9999 ------- 22:13 47115 0.0 bias ----- sequence 47116, plate 2695 ------- 22:20 47116 10.0 flat 22:23 47117 2.0 arc 22:29 47118 3.0 arc Hartmann 22:32 47119 3.0 arc Hartmann 23:45 47121 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:55Z imager 1.00000 0 -180 -90 -35 51.9 6.3 14 88 23 2.8 03:40Z imager 1.00000 0 -340 -250 -35 51.9 5.2 19 83 23 3.1 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:03Z 54 24 6 261 (W) 2211 - clear 21:36Z 58 24 8 229 (SW) 2062 - clear 22:07Z 56 22 5 213 (SSW) 1813 - clear 22:38Z 56 21 5 260 (W) 1332 - clear 23:08Z 54 21 4 239 (WSW) 1595 - clear 00:11Z 49 19 1 157 (SSE) 1209 - 00:44Z 46 24 8 84 (E) 1903 - 01:15Z 44 24 12 88 (E) 2771 - 01:46Z 43 25 12 86 (E) 2853 - 02:17Z 42 22 15 82 (E) 2642 - 02:49Z 41 21 22 76 (ENE) 2605 - 03:21Z 42 20 22 90 (E) 2349 - 03:53Z 40 20 25 76 (ENE) 2286 - 04:25Z 37 20 23 74 (ENE) 2590 - 04:57Z 35 20 19 79 (E) 2733 - 05:29Z 35 20 14 89 (E) 3346 - 06:00Z 35 20 14 83 (E) 3132 - 06:31Z 35 21 14 85 (E) 3588 - 07:01Z 36 22 11 88 (E) 3377 - 07:31Z 36 22 11 88 (E) 3494 - 08:02Z 37 23 9 86 (E) 3204 - 08:34Z 37 23 9 103 (ESE) 3180 - 09:04Z 36 23 12 80 (E) 3223 - 09:35Z 38 23 6 127 (SE) 3170 - 10:07Z 42 23 4 98 (E) 2722 - 10:38Z 40 23 3 96 (E) 2832 - 11:12Z 41 24 8 141 (SE) 2445 - ---=== TELESCOPE STATUS ===--- 23:15Z - Began ventilation.
