When I went to re-start I was getting motion errors in Alt and Az. Looks like we had a dome collision. I moved the telescope off the stops and things worked fine after I re-initialized. No other 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 -------------------------------------------------------------------------- 18:46 ecamera 440( 506) 89 65 14.3 16.3 16.1 15.7 15.1 ND1 0.99 01:13 arctic 297( 1339) 137 55 14.8 13.7 14.4 13.5 14.1 4170 1.24 01:15 NA2gdr -2141(35858) 137 55 15.0 13.6 14.4 13.5 14.1 R 1.15 05:16 arctic 350( 1127) 24 54 5.9 7.9 9.1 7.4 6.4 3500 5.50 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 65 25 12 261 (W) 872 clear none 17:00 64 25 7 216 (SW) 769 clear none 18:00 62 21 13 260 (W) 700 clear none 19:00 59 20 16 225 (SW) 589 clear none 20:00 59 18 19 218 (SW) 524 clear none 21:00 59 18 15 221 (SW) 541 clear none 22:00 58 15 13 235 (SW) 591 clear none 23:00 58 12 10 217 (SW) 419 clear none 00:00 59 13 8 231 (SW) 397 mstly clr none 01:00 59 13 4 205 (SSW) 315 mstly clr none 02:00 59 13 7 82 (E) 325 clear none 03:00 57 15 17 75 (ENE) 398 clear none 04:00 51 14 19 75 (ENE) 386 clear none 05:00 43 27 21 74 (ENE) 1400 clear none 06:00 42 28 16 76 (ENE) 1185 clear none Note: the wind was coming from the azimuth listed.
