APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday October 24, 2006 (MJD 54033) ---=== OBSERVING TEAM ===--- Swing: Viktor Malanushenko Observers: Howard Brewington & Kaike Pan ---=== OBSERVING PLAN ===--- superNova Science! ---=== OBSERVING SUMMARY ===--- Clouds and high humidity, so we never opened. ---=== OBSERVING LOG ===--- Afternoon: ---------- Telescope has been checked. All systems work fine. Spectro Collimation has been done and focusing on expected night temp.= +4.0 C. Time exposure on Spectro Collimation has been equal 3 sec. The PT has been checked. It works good; Biases and Dom Flats have been obtained. Disk space has been checked and cleaned. Now there is: /files partition ~102 Gb and /data partition ~384 Gb. Night: ------ 00:19Z Clouds and high humidity at sunset, so we waited. 09:00Z The humidity reading at the 2.5-meter started to drop. However, the humidity at the 3.5-meter was still 100%. We checked outside and discovered that the high humidity conditions still remained. We are not sure what caused the false reading at the 2.5-meter. 10:46Z We still had clouds and very high humidity, so we went to bed. endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6489 21:40Z 22:04Z 100 O 67.46 73.37 53 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): y QA Procedures Done (y/n): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 41152, plate 2441 ------- 21:30 41152 0.0 bias 21:51 41153 10.0 flat 21:53 41154 2.0 arc 22:07 41155 3.0 arc 22:09 41156 3.0 arc ----- sequence 41157, plate -9999 ------- 00:15 41157 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 ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 19:27Z 44 42 15 180 (S) 529 - 19:59Z 44 42 18 186 (S) 540 - 20:32Z 43 43 16 195 (SSW) 516 - 21:04Z 42 42 10 228 (SW) 4522 - 21:36Z 42 43 9 236 (SW) 8509 - 22:07Z 43 43 8 272 (W) 11708 - 22:37Z 42 42 7 275 (W) 15524 - 23:08Z 42 43 6 267 (W) 9061 - 23:40Z 42 42 8 295 (WNW) 6353 - 00:17Z 41 42 12 281 (W) 1657 - 00:49Z 41 41 12 300 (WNW) 14590 - 01:21Z 41 41 7 270 (W) 25197 - 01:53Z 40 41 13 294 (WNW) 13524 - 02:25Z 40 40 14 253 (WSW) 2514 - 02:57Z 40 41 15 265 (W) 105191 - 03:33Z 41 41 15 278 (W) 148131 - 04:06Z 40 41 13 267 (W) 120254 - 04:38Z 41 41 15 262 (W) 20546 - 05:10Z 41 41 16 265 (W) 12008 - 05:42Z 41 41 20 283 (WNW) 28266 - 06:14Z 40 41 21 276 (W) 68997 - 06:46Z 41 41 17 286 (WNW) 32431 - 07:18Z 41 41 16 283 (WNW) 13217 - 07:50Z 41 42 20 292 (WNW) 14281 - 08:27Z 41 41 16 282 (WNW) 81426 - 08:59Z 40 40 21 284 (WNW) 34706 - 09:31Z 40 41 17 267 (W) 118655 - 10:03Z 40 41 16 259 (W) 76790 - 10:35Z 41 41 15 274 (W) 13540 - ---=== TELESCOPE STATUS ===--- We never opened.
