Doing an expose init resolved the issue. We had clouds at the start of the night, they formed over us during the first half which prevented us from opening. Around 23:30 we got a few sprinkles. Around 00:15 things started to improve, we still had clouds but the rain threat seemed to be moving away. By 00:30 I thought it was safe to finally open. Unfortunately the 1st half program needed 45-60 per exposure so they just let the 2nd program take their remaining few minutes. I just marked their time as a weather loss. No problems 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 -------------------------------------------------------------------------- 01:24 ecamera 284( 5) -7 52 17.7 18.4 18.7 18.0 17.7 ND3 0.81 03:37 ecamera 423( 89) -31 53 17.2 17.3 17.8 17.0 17.1 ND1 0.92 05:03 ecamera 351( -18) 134 42 16.5 16.3 16.9 15.9 16.1 ND2 0.93 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 69 44 1 222 (SW) 730 ptly cldy none 17:00 71 43 5 194 (SSW) 713 ptly cldy none 18:00 71 43 7 143 (SE) 779 ptly cldy none 19:00 67 40 6 115 (ESE) 822 ptly cldy none 20:00 68 36 8 227 (SW) 882 mstly cldy none 21:00 68 35 8 184 (S) 882 mstly cldy none 22:00 67 35 11 161 (SSE) 813 mstly cldy none 23:00 67 36 12 170 (S) 835 mstly cldy lt rain 00:00 64 34 13 179 (S) 1533 ptly cldy none 01:00 63 32 8 191 (S) 1836 ptly cldy none 02:00 64 33 4 204 (SSW) 1079 mstly clr none 03:00 63 25 6 190 (S) 1548 clear none 04:00 63 26 7 282 (WNW) 1263 clear none 05:00 61 30 6 342 (NNW) 896 mstly clr none 06:00 63 31 9 321 (NW) 737 ptly cldy none Note: the wind was coming from the azimuth listed.
