The seeing was moderate, degrading as the night went on and the winter front started getting closer. However, we were able to stay open until dawn and the trainees were able to get all the photons! At 03:56 am there was a altitude motion error at 73.5 going from 75 to 69.3. An axis init fixed the issue and we had no further problems. ------- 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 -------------------------------------------------------------------------- 17:12 ecamera 412( -406) 87 69 2.2 5.0 4.6 4.5 3.1 ND5 0.99 19:55 ecamera 436( -548) 86 47 2.5 1.2 2.5 1.8 2.2 ND2 1.01 00:29 kosmos 454( 562) -40 27 2.9 1.8 3.1 2.7 3.1 -- 1.46 01:40 kosmos 594( 676) -72 42 2.2 1.5 2.8 2.2 2.3 -- 1.18 02:30 kosmos 400( 476) -74 24 1.4 1.0 2.2 1.4 1.5 -- 2.00 04:02 arctic 411( 493) 31 70 1.7 0.8 1.8 1.3 1.6 CU-VR 1.02 04:54 arctic 411( 482) -80 63 0.6 0.5 1.3 0.7 0.9 CU-VR 1.52 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 42 17 16 196 (SSW) 498 mstly clr none 17:00 37 17 10 185 (S) 663 mstly clr none 18:00 36 19 15 194 (SSW) 825 mstly clr none 19:00 36 16 11 191 (S) 619 mstly clr none 20:00 36 3 17 181 (S) 274 mstly clr none 21:00 37 -6 19 188 (S) 131 clear none 22:00 38 -3 21 196 (SSW) 207 clear none 23:00 38 8 20 222 (SW) 385 clear none 00:00 37 8 20 199 (SSW) 361 clear none 01:00 37 10 26 198 (SSW) 396 clear none 02:00 35 9 23 206 (SSW) 342 clear none 03:00 35 12 22 200 (SSW) 391 clear none 04:00 35 13 28 209 (SSW) 360 clear none 05:00 33 11 26 257 (WSW) 359 clear none 06:00 32 7 24 254 (WSW) 366 clear none Note: the wind was coming from the azimuth listed.
