APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday March 10, 2010 (MJD 55266) ---=== OBSERVING TEAM ===--- Audrey Simmons Dmitry Bizyaev ---=== OBSERVING PLAN ===--- Measuring cosmological parameters of the Universe with BOSS spectrograph. ---=== OBSERVING SUMMARY ===--- Night was lost completely due to clouds, high humidity, and snow. ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon checkout went ok. We had some snow flakes falling in the evening, before sunset. 00:45Z started ventilation Delayed opening because of dangerous clouds. Night: ------ 02:00Z wind is still high, and sky is overcast. We have not opened yet. 03:03Z ventilation stopped because of combination of rising humidity (> 70%) and dust counts (> 3000 and rising). 05:00Z ventilation started because due point difference goes up. Sky is cloudy. 08:05Z ventilation stopped again: humidity climbs up. 10:52Z show started We called it a night and power down amplifiers. 11:05Z endNight finished. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ---=== 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 00:31Z 26 13 29 267 (W) 881 - 01:05Z 25 11 22 260 (W) 1110 - 01:35Z 24 13 27 274 (W) 1079 - 02:05Z 23 14 23 266 (W) 1216 - cloudy 02:39Z 22 13 19 261 (W) 1046 - '' 03:09Z 21 13 16 268 (W) 5626 - '' 03:42Z 20 12 21 292 (WNW) 3106 - '' 04:12Z 20 13 16 288 (WNW) 1771 - '' 04:46Z 20 12 11 282 (WNW) 1157 - '' 05:19Z 20 11 17 283 (WNW) 1124 - '' 05:49Z 20 10 17 298 (WNW) 987 - '' 06:24Z 19 10 21 287 (WNW) 969 - '' 06:57Z 19 9 13 275 (W) 983 - '' 07:30Z 19 10 27 294 (WNW) 973 - '' 08:04Z 18 11 20 277 (W) 963 - '' 08:38Z 17 13 19 285 (WNW) 925 - '' 09:11Z 17 12 21 275 (W) 1001 - '' 09:45Z 16 11 21 288 (WNW) 1063 - '' 10:15Z 15 10 13 267 (W) 1124 - '' 10:48Z 15 11 12 285 (WNW) 1199 - '' ---=== TELESCOPE STATUS ===--- 00:45Z - Began ventilation.
