APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday January 23, 2008 (MJD 54489) ---=== OBSERVING TEAM ===--- Audrey Simmons Kaike Pan Shannon Watters (afternoon) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We lost the night due to clouds, high humidity, and snow. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working. Spectrograph focus set for approximately -1C to -1.5C. 00:10Z - Started ventiliation with doors and louvers open, fans on. Night: ----- 00:44Z - Stopped ventilating because of high humidity and thick clouds. 07:58Z - Rain sensor went off. It started snowing. 10:24Z - Double checked collimation. All motors are right where they should be (temperature of -1C to -1.5C). There is no hope for us to open. We called it a night. 11:35Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7297 22:43Z 23:01Z 100 O 172.49 -182.95 44 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): no UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 49273, plate -9999 ------- 22:07 49273 0.0 bias ----- sequence 49274, plate 2659 ------- 23:38 49274 10.0 flat 23:41 49275 2.0 arc 23:44 49276 3.0 arc 23:47 49277 3.0 arc ----- sequence 49278, plate -9999 ------- 00:07 49278 0.0 bias 00:16 49279 0.0 bias ----- sequence 49280, plate 2659 ------- 06:47 49280 3.0 arc 06:50 49281 3.0 arc 09:56 49282 3.0 arc 09:59 49283 2.0 arc ---=== 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:16Z 33 17 7 289 (WNW) 543 - Cloudy 21:48Z 34 18 9 287 (WNW) 509 - " 22:21Z 33 20 5 264 (W) 342 - " 22:54Z 35 23 6 266 (W) 366 - " 23:24Z 35 21 8 269 (W) 411 - " 23:54Z 32 17 1 218 (SW) 515 - " 00:40Z 31 26 8 266 (W) 274 - " 01:13Z 31 27 6 256 (WSW) 313 - High humidity 01:46Z 31 27 5 250 (WSW) 341 - " 02:19Z 30 26 6 254 (WSW) 418 - " 02:51Z 30 25 7 223 (SW) 421 - " 03:23Z 30 23 3 249 (WSW) 469 - Cloudy 03:55Z 30 24 6 223 (SW) 535 - " 04:27Z 29 21 6 208 (SSW) 678 - High humidity 04:59Z 30 25 3 175 (S) 612 - " 05:31Z 31 27 1 185 (S) 365 - " 06:08Z 30 23 8 167 (SSE) 710 - " 06:44Z 29 23 11 167 (SSE) 702 - " 07:15Z 30 23 8 169 (S) 488 - " 07:47Z 30 23 9 170 (S) 462 - Snowy 08:20Z 30 23 15 182 (S) 513 - " 08:52Z 28 26 10 174 (S) 585 - " 09:24Z 27 26 12 162 (SSE) 559 - " 09:57Z 30 26 18 194 (SSW) 715 - " 10:28Z 29 25 18 158 (SSE) 976 - " 11:00Z 29 25 12 193 (SSW) 694 - 11:32Z 27 26 20 154 (SSE) 1145 - ---=== TELESCOPE STATUS ===--- 00:10Z Doors cracked open, fans and blowers on, louvers opened. 00:44Z - Stopped ventilating because of high humidity.
