APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday December 8, 2004 (MJD 53348) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Steph Snedden Jurek Krzesinski ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We've got veriety of weather problems (high humidity, clouds and high wind). Only one exposure with good S/N was done tonight on plate 1932. No problems to report. ---=== OBSERVING LOG ===--- Afternoon: ---------- Checkout went smoothly. No focus adjustment to spectrographs needed. Night: ------ High humidity kept us closed for the first half of the night. 06:55Z We finaly opened. Dewars refilled, cart 4 plt. 1932 mounted. Stars on slew after clearing offsets from the previous nights. Unfortunately the clouds got thick and we barely could see the guiding stars. But after a while the efficiency went up. Whe've got one good exposure on that plate, but the second one got S/N below 2 in r2 (1.95) in 20 minutes exposure. we declared that exposure bad. 10:15Z clouds. Wind gusts to high (and blown snow): 11:00Z telescope closed. 12:10Z endNight run ok. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5031 22:13Z 22:37Z 100 O 120.62 126.39 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 22:27 29736 2.0 arc 22:34 29737 2.1 arc 22:36 29738 2.1 arc ----- sequence 29739, plate -9999 ------- 22:54 29739 0.0 bias ----- sequence 29740, plate 1932 ------- 07:40 29740 10.0 flat 07:42 29741 2.0 arc 08:07 29742 1200.1 target good 08:29 29743 1200.1 target bad ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 07:45Z 4 1932 93.09 0.0001 52.06 0.0022 250.43 -0.0016 1.000300 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL8130 Stays: JL8131 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 07:45Z 4 1932 1.00030 -2961 -1077 200 93 52.0 -0.9 5 357 gdr 2.0 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:28Z 29 19 14 298 (WNW) 66 - Mostly Clear 22:59Z 28 20 13 297 (WNW) 120 - Mostly Clear 23:29Z 27 21 15 291 (WNW) 119 - Clear 00:18Z 26 23 15 303 (WNW) 195 - 00:50Z 27 24 16 307 (NW) 262 - 01:22Z 27 25 12 306 (NW) 378 - 01:54Z 27 26 17 298 (WNW) 437 - 02:27Z 27 26 19 301 (WNW) 582 - 02:59Z 27 26 18 298 (WNW) 609 - 03:31Z 27 26 19 305 (NW) 527 - 04:03Z 27 25 19 308 (NW) 255 - 04:36Z 27 24 15 315 (NW) 224 - 05:08Z 27 24 14 357 (NNW) 178 - 05:40Z 28 23 16 327 (NNW) 135 - 06:12Z 29 23 24 321 (NW) 99 - 06:44Z 28 22 14 306 (NW) 94 - 07:15Z 29 22 13 337 (NNW) 101 - 07:46Z 30 20 15 340 (NNW) 81 - 08:16Z 31 19 20 324 (NW) 63 - 08:46Z 31 19 7 0 (N) 56 - 09:18Z 30 20 6 5 (N) 74 - 09:51Z 30 21 20 344 (NNW) 87 - 10:23Z 32 19 8 4 (N) 72 - 10:55Z 32 19 23 5 (N) 73 - 11:27Z 32 20 29 1 (N) 92 - 12:00Z 33 19 12 14 (NNE) 156 - ---=== TELESCOPE STATUS ===--- 23:00Z Doors Open, Fans On 00:11Z Fans off (Dew point too low). 00:20Z Doors closed. 06:54Z Telescope opened, fans on, LN2 dewars refilled. 11:00Z Telescope closed.
