APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday December 1, 2007 (MJD 54436) ---=== OBSERVING TEAM ===--- Elena Malanushenko (swing) Howard Brewington Audrey Simmons Shannon Watters (imager calibrations) Mamoru Doi (imager calibrations) ---=== OBSERVING PLAN ===--- SEGUE Science! ---=== OBSERVING SUMMARY ===--- The weather was nasty all night, so we never opened. Note: When we went to close the PT, the combination door lock was covered in ice/snow. It took a few minutes to warm the pad up just to get in the door. Is there a cover that we can put on it for these situations? ---=== OBSERVING LOG ===--- Afternoon: ---------- All equipment are checked and working properly. Spectro collimation set for ~1.5C. Diskspace is now on 251G /data and on 267G /files. MJDs deleted: 54412-54415. Ventilation is not started because of 100% humidity. Night: ------ Did not open at all due to clouds, fogg, high wind, rain, snow, ice... Basically every weather problem you can think of. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7206 23:03Z 23:07Z 100 O 125.33 126.32 21 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 23:25 47615 3.0 arc 23:28 47616 3.0 arc 23:35 47617 10.0 flat 23:38 47618 2.0 arc 23:43 47619 0.0 bias ----- sequence 47620, plate -9999 ------- 00:04 47620 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 ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:04Z 36 37 25 255 (WSW) 4744 - Cloudy, foggy 23:37Z 36 37 29 266 (W) 106301 - " 00:09Z 35 35 29 265 (W) 831 - " 00:41Z 34 34 24 267 (W) 756 - " 01:13Z 34 35 30 246 (WSW) 643 - " 01:45Z 33 34 24 253 (WSW) 655 - " 02:18Z 33 33 33 257 (WSW) 555 - " 02:50Z 33 33 35 260 (W) 539 - Rainy/snowy 03:22Z 33 32 29 251 (WSW) 473 - " 03:54Z 33 32 26 229 (SW) 390 - " 04:27Z 33 32 26 259 (W) 477 - " 04:59Z 32 32 22 265 (W) 433 - " 05:31Z 32 32 31 248 (WSW) 317 - " 06:03Z 32 32 31 259 (W) 375 - " 06:35Z 32 32 25 256 (WSW) 5152 - " 07:08Z 31 32 39 259 (W) 5325 - " 07:40Z 31 31 35 256 (WSW) 7570 - " 08:12Z 31 31 31 258 (WSW) 8495 - " 08:44Z 30 31 23 274 (W) 7816 - " 09:16Z 30 31 29 259 (W) 5491 - " 09:48Z 30 30 28 270 (W) 8413 - " 10:21Z 30 31 37 286 (WNW) 1534 - " ---=== TELESCOPE STATUS ===--- 10:41Z - Enclosure remained on, doors and louvers remained closed, and fans remained off.
