APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 10, 2007 (MJD 54262) ---=== OBSERVING TEAM ===--- Stephanie Snedden Dmitry Bizyaev ---=== OBSERVING PLAN ===--- Science: spectroscopy. ---=== OBSERVING SUMMARY ===--- Clouds and lightnings except in the last hour before morning. One good spectro exposure (SEGUE) has been taken. ---=== OBSERVING LOG ===--- 02:20Z - ventillation started. Not opening because of clouds/rain coming from the south. 09:30Z - dome opened. Clouds were mostly gone. 09:40Z - Observed cart.8, plate 2554 (SEGUE). GSOGTF, 2 exposures, first was good 15 min, second (20 min) was bad because of clouds. Plate is not done. 10:53Z - dome closed. endNight rejoiced. ---=== 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 ----- sequence 45273, plate 1791 ------- 01:43 45273 10.0 flat 01:45 45274 2.0 arc 01:48 45275 3.0 arc Hartman's 01:51 45276 3.0 arc Hartman's ----- sequence 45277, plate 2554 ------- 09:45 45277 10.0 flat 09:47 45278 2.0 arc 10:06 45279 900.0 target 10:31 45280 1202.0 target 10:34 45281 10.0 flat 10:36 45282 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 09:52Z 8 2554 178.56 0.0017 62.72 0.0031 -2.53 -0.0147 1.000200 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 09:52Z 8 2554 1.00020 -1975 -539 -50 179 62.7 13.1 12 179 - 1.6" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 01:43Z 62 41 6 258 (WSW) 659 - cloudy 02:13Z 59 43 9 143 (SE) 586 - - 02:44Z 59 43 12 156 (SSE) 611 - - 03:14Z 59 42 14 162 (SSE) 611 - - 03:44Z 58 43 14 160 (SSE) 592 - - 04:15Z 59 42 12 171 (S) 623 - - 04:46Z 59 42 11 173 (S) 598 - - 05:17Z 55 45 18 186 (S) 1462 - - 05:47Z 54 46 19 154 (SSE) 1424 - - 06:18Z 54 46 18 138 (SE) 777 - - 06:50Z 55 46 19 145 (SE) 924 - - 07:20Z 55 45 14 173 (S) 915 - - 07:51Z 55 45 14 179 (S) 933 - - 08:22Z 55 44 8 179 (S) 783 - - 08:53Z 55 42 11 179 (S) 577 - - 09:23Z 56 45 15 177 (S) 643 - partly cloudy 09:53Z 55 44 13 180 (S) 646 - - 10:23Z 55 41 9 185 (S) 533 - - 10:53Z 54 41 6 180 (S) 545 - - ---=== TELESCOPE STATUS ===--- see main body of the log for opening and closing times The telescope is stoved at 30 deg ALT, 121 deg AZ, ROT=0 deg, cart.8 is mounted, counterweights =250, spectro autofill connected.
