Dataq had to be restarted. The sky was clear all night with moderate seeing that improved for UW02 with KOSMOS and slightly again for B Half. KOSMOS start time was set when I started focusing KOSMOS while awaiting the first object slew, which followed immediately after focusing was complete. The times listed in the focus log seem to be Daylight Saving Time (for ex., echelle was focused at 00:03 MST) If each ObsSpec was supposed to adjust something, I have not done so since the time switch which might affect the logs for Nov 7, 8, 19, 20 and tonight. End of night echelle IOL was precluded by observer cals that will run for 2.5 hours. No telescope issues tonight. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 17:38 ecamera 377( -226) 4 44 2.2 1.8 3.0 2.1 2.2 ND4 2.20 21:03 kosmos 325( 647) 8 67 0.9 0.5 1.6 0.7 0.8 - 1.30 00:03 ecamera 308( -345) 348 46 0.7 0.7 1.8 1.3 1.4 ND4 1.20 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 40 6 12 199 (SSW) 1066 clear none 17:00 36 5 15 255 (WSW) 1329 clear none 18:00 36 5 19 266 (W) 1949 clear none 19:00 36 3 20 270 (W) 2593 clear none 20:00 35 3 16 291 (WNW) 2718 clear none 21:00 34 3 13 300 (WNW) 1120 clear none 22:00 35 2 8 303 (WNW) 674 clear none 23:00 36 1 20 317 (NW) 698 clear none 00:00 35 1 15 328 (NNW) 607 clear none 01:00 35 0 10 300 (WNW) 487 clear none 02:00 36 0 16 327 (NNW) 776 clear none 03:00 34 -1 13 330 (NNW) 632 clear none 04:00 35 0 12 348 (NNW) 605 clear none 05:00 36 -2 3 327 (NNW) 427 clear none 06:00 34 -9 9 356 (N) 337 clear none Note: the wind was coming from the azimuth listed.
