This is the same time they locked up yesterday, and I believe the day before that. PR sent. We had a late telescope tour at 20:00 tonight, which was fine since we were closed during that time due to clouds. 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 -------------------------------------------------------------------------- 01:29 arctic 5( 1200) 72 80 16.1 17.1 19.0 16.7 16.2 SDSS_i 1.22 04:22 ecamera 284( 266) 269 62 15.7 14.5 15.3 14.3 14.9 ND1 1.49 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 60 48 18 27 (NNE) 1344 cloudy none 17:00 69 44 1 342 (NNW) 731 cloudy none 18:00 69 45 2 218 (SW) 977 cloudy none 19:00 69 43 4 23 (NNE) 980 cloudy none 20:00 66 49 17 130 (SE) 1291 cloudy none 21:00 62 49 21 141 (SE) 1551 mstly cldy none 22:00 63 49 17 182 (S) 2458 ptly cldy none 23:00 63 45 6 198 (SSW) 1332 cloudy none 00:00 61 47 9 306 (NW) cloudy lt rain 01:00 61 47 2 335 (NNW) ptly cldy none 02:00 61 49 11 205 (SSW) ptly cldy none 03:00 57 49 4 181 (S) 2544 ptly cldy none 04:00 59 49 2 193 (SSW) 3508 ptly cldy none 05:00 61 49 3 244 (WSW) 2303 ptly cldy none 06:00 60 49 8 2 (N) 2313 ptly cldy none Note: the wind was coming from the azimuth listed.
