APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday November 29, 2007 (MJD 54434) ---=== OBSERVING TEAM ===--- Elena Malanushenko (day) Dan Oravetz (observer) Howard Brewington (observer) ---=== OBSERVING PLAN ===--- SN & SEGUE Science! ---=== OBSERVING SUMMARY ===--- We never opened. The night was lost to high humidity, clouds, and rain...lots of rain. ---=== OBSERVING LOG ===--- Afternoon: ---------- All equipment checked and working properly. Spectro collimation set for ~3C. Diskspace was 207G available on /data and 45G available on /files, so 'byebye' was run on MJD's 54410 and 54411. Now there are 220G available on /data and 112G available on /files. Did not start ventilation because of high humidity. Night: ------ High humidity, clouds, and rain all night long. 10:33Z - When we went down into the lower enclosure to turn things off, there were puddles of water on the floor on the west side. Howard put some absorbent pads down. 11:00Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7203 22:28Z 22:47Z 100 O 114.55 119.50 45 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): n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 47598, plate -9999 ------- 21:56 47598 0.0 bias ----- sequence 47599, plate 2807 ------- 22:32 47599 10.0 flat 22:35 47600 2.0 arc 22:38 47601 3.0 arc Hartmann 22:41 47602 2.0 arc Hartmann ----- sequence 47603, plate -9999 ------- 23:58 47603 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 20:32Z 37 35 13 266 (W) 441 - clouds 21:05Z 38 32 17 266 (W) 325 - clouds 21:37Z 39 34 16 260 (W) 278 - clouds 22:07Z 39 34 15 266 (W) 269 - clouds 22:39Z 38 35 18 269 (W) 260 - clouds 23:09Z 39 36 15 274 (W) 262 - clouds 23:41Z 39 39 17 285 (WNW) 277 - clouds 00:13Z 40 40 16 260 (W) 2747 - clouds 00:45Z 40 40 22 269 (W) 8229 - clouds 01:18Z 40 40 23 251 (WSW) 1795 - clouds 01:50Z 40 41 18 268 (W) 1256 - clouds 02:22Z 39 40 21 267 (W) 6502 - clouds 02:54Z 39 39 20 259 (W) 4048 - clouds 03:26Z 39 39 16 259 (W) 1908 - clouds 04:02Z 39 39 21 255 (WSW) 9751 - clouds 04:34Z 39 39 17 255 (WSW) 51182 - clouds 05:07Z 39 40 14 263 (W) 2787 - clouds 05:39Z 40 41 20 267 (W) 16885 - clouds 06:11Z 40 41 16 251 (WSW) 21155 - clouds 06:43Z 40 41 22 267 (W) 7229 - clouds 07:15Z 40 41 14 266 (W) 10551 - clouds 07:47Z 39 40 12 257 (WSW) 15445 - clouds 08:19Z 40 40 15 253 (WSW) 18663 - clouds 08:52Z 40 41 18 241 (WSW) 12648 - clouds 09:24Z 40 41 15 264 (W) 11261 - clouds 09:56Z 40 41 17 240 (WSW) 14710 - clouds 10:28Z 41 41 13 245 (WSW) 14347 - clouds ---=== TELESCOPE STATUS ===--- We never opened due to uncooperative weather.
