Humidity went over the limit around midnight for about 1 hr which caused us to close. My 2nd observer had an issue where the KOSMOS slitviewer wasn't updating images. I had him restart TUI which fixed the issue. No telescope 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 -------------------------------------------------------------------------- 19:21 ecamera 417( 31) 82 73 3.9 6.8 6.7 7.1 4.7 ND1 1.07 01:20 ecamera 414( -86) -116 43 6.1 3.9 4.7 3.9 5.2 ND3 1.26 02:11 kosmos 306( 847) 13 57 3.8 4.0 5.0 4.3 4.4 -- 1.32 05:25 tcamera 399( 1170) -111 52 5.7 4.6 5.4 4.8 5.2 Ks 0.90 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 42 36 4 257 (WSW) 812 mstly cldy none 17:00 44 36 12 236 (SW) 936 mstly cldy none 18:00 43 37 10 260 (W) 1018 ptly cldy humid 19:00 39 35 9 259 (W) clear none 20:00 39 34 7 260 (W) 948 clear none 21:00 40 34 3 193 (SSW) 1135 clear none 22:00 40 32 2 187 (S) 834 clear none 23:00 44 33 2 267 (W) 539 clear none 00:00 39 36 4 214 (SW) clear humid 01:00 40 36 1 247 (WSW) clear none 02:00 41 34 5 342 (NNW) 507 clear none 03:00 42 33 9 307 (NW) 445 clear none 04:00 41 34 11 340 (NNW) 447 clear none 05:00 42 34 11 336 (NNW) 581 clear none 06:00 42 34 12 312 (NW) 627 clear none Note: the wind was coming from the azimuth listed.
