Seems like we have seen this in the past with this camera. At 00:05 we had a mirror issue the secondary not moving correctly (A) and throwing an error. I called Russet and she quickly fixed the issue without the need to home the secondary. Unfortunately the humidity shot over the limit after the fix so we had to delay the start of the last program. We had off and on occurrences of humidity tonight. At 03:50 the humidity finally shot up again to force us to close, a short time later we had fog fomr on the site. I gave up at 05:00 with humidity at 100% and fog outside. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:51 ecamera 602( -385) -81 74 -0.9 3.3 3.1 2.7 0.6 ND1 1.18 20:25 ecamera 812( -245) 73 31 -1.8 1.4 2.7 0.9 -1.0 ND3 1.60 22:00 ecamera 553( -559) 44 36 -1.6 0.3 1.6 -0.2 -0.9 ND4 1.00 02:04 dcamera 835( 425) -35 52 -2.3 -2.3 -1.3 -2.8 -2.7 -- 1.50 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 35 33 1 214 (SW) cloudy humid 17:00 33 31 6 96 (E) cloudy humid 18:00 32 28 6 95 (E) ptly cldy humid 19:00 30 26 8 93 (E) ptly cldy none 20:00 30 25 5 97 (E) mstly clr humid 21:00 30 25 9 165 (SSE) clear humid 22:00 29 23 12 170 (S) clear none 23:00 28 22 14 168 (SSE) clear none 00:00 27 23 11 153 (SSE) clear humid 01:00 27 23 15 146 (SE) clear humid 02:00 27 22 13 145 (SE) clear none 03:00 29 22 11 168 (SSE) clear none 04:00 29 27 12 176 (S) ptly cldy fog 05:00 29 29 11 170 (S) mstly cldy fog Note: the wind was coming from the azimuth listed.
