APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 23, 2007 (MJD 54124) ---=== OBSERVING TEAM ===--- Kaike Pan Olena Malanushenko Audrey Simmons Mike Harvanek (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We did not open this night because high humidity and strong wind with blowing snow. Spectro is in auto mode and filled itsef at 4:30Z in 18 hours after previous filling. It is very slippery inside PT dome because ice and a lot of snow. ---=== OBSERVING LOG ===--- Afternoon: ---------- The 90 degree alt fiducial did not read in either direction. The 45 degree alt fiducial did not read going up. Spectro collimation was adjusted. Details are in the Problems section. Nothing else to report. Night: ------ Some low clouds are moving from NE and some other are formed under telescope in low valley. T=-5.7 C, humidity 87 %, diff 1.9 C. Dust 400 counts. Wind detector does not work. We have layer of snow on the telescope building and some snow from nearby trees is blowing around. Cloud camera is unavailable due to engineering work. 00:30 Z We cannot open now and wait for weather improving. Dominated problem is a humidity. 02:50 Z Humidity dropped down to 77 % and diff up to 4 C; removed flag of high humidity. We have strong NE wind and a lot of snow is blowing on cite. We cannot open and use no activity flag of other weather problem. We also added strong wind flag of non-activity even we do not know the speed of wind. 03:25 Z French and Mike have mounted Cloud camera and it works. It has been closed soon because of blowing snow. 04:30 Z Spectro filled itsef in auto mode. Previous filling was 18 hours ago. It tooks 45 lb. It is very slippery inside PT dome. We did not opened. 10:40 Z endNight is completed. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6685 22:14Z 22:34Z 100 O 165.46 170.47 47 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): yes QA Procedures Done (y/n): yes UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 42610, plate -9999 ------- 22:09 42610 0.0 bias ----- sequence 42611, plate 2637 ------- 23:20 42611 10.0 flat 23:22 42612 2.0 arc 23:53 42613 10.0 flat 23:56 42614 2.0 arc 00:12 42615 10.0 flat 00:15 42616 2.0 arc ----- sequence 42617, plate -9999 ------- 00:40 42617 0.0 bias 00:45 42618 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 21:13Z 26 20 -9999 -9999 (N) 321 - 21:45Z 27 21 -9999 -9999 (N) 270 - 22:15Z 26 19 -9999 -9999 (N) 301 - 22:46Z 25 20 -9999 -9999 (N) 250 - 23:18Z 24 19 -9999 -9999 (N) 264 - 23:50Z 23 19 -9999 -9999 (N) 580 - 00:23Z 22 19 -9999 -9999 (N) 254 - partly cloudy 00:51Z 21 18 -9999 -9999 (N) 401 - 01:23Z 21 18 -9999 -9999 (N) 279 - 01:55Z 20 17 -9999 -9999 (N) 450 - 02:27Z 19 14 -9999 -9999 (N) 336 - 02:59Z 18 12 -9999 -9999 (N) 251 - 03:31Z 17 9 -9999 -9999 (N) 605 - 04:04Z 17 6 -9999 -9999 (N) 1274 - 04:36Z 16 6 -9999 -9999 (N) 1610 - 05:08Z 16 5 -9999 -9999 (N) 618 - 05:40Z 16 3 -9999 -9999 (N) 197 - 06:12Z 16 0 -9999 -9999 (N) 285 - 06:44Z 16 -1 -9999 -9999 (N) 323 - 07:16Z 16 -3 -9999 -9999 (N) 176 - 07:49Z 17 -1 -9999 -9999 (N) 231 - 08:21Z 16 0 -9999 -9999 (N) 288 - 08:53Z 17 8 -9999 -9999 (N) 132 - 09:25Z 18 13 -9999 -9999 (N) 156 - 09:57Z 18 11 -9999 -9999 (N) 257 - 10:29Z 18 12 -9999 -9999 (N) 109 - ---=== TELESCOPE STATUS ===--- Never opened or ventilated.
