The old dewpoint sensor seemed froze so I used the optidew sensors. We closed about 10 mins before the start of twilight due to the humidity. I did not take an end of night Echelle IOL since the observer was taking their cals. ------- 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 -------------------------------------------------------------------------- 20:36 ecamera 417( -58) -83 49 11.6 14.1 14.7 13.1 12.2 clear 3.25 21:15 ecamera 525( -26) -89 41 11.4 12.4 13.3 11.7 11.6 clear 3.40 00:10 APOLLO 500( 1591) -34 40 10.2 10.1 10.8 10.0 10.1 -- 2.50 01:14 tcamera 426( 1032) 7 63 9.8 9.7 10.4 9.7 9.8 Ks 1.64 02:48 ecamera 454( -246) 123 61 10.3 9.6 10.1 9.7 10.2 clear 1.49 04:25 ecamera 525( -220) 182 72 8.0 8.7 9.5 8.6 8.2 clear 2.90 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 63 30 21 182 (S) 2092 mstly cldy none 17:00 64 33 12 177 (S) 2615 ptly cldy none 18:00 59 29 20 117 (ESE) 3245 ptly cldy none 19:00 56 24 22 113 (ESE) 3446 ptly cldy none 20:00 53 32 19 119 (ESE) 2733 mstly clr none 21:00 52 32 14 100 (E) 2718 mstly clr none 22:00 52 31 23 127 (SE) ptly cldy none 23:00 51 31 17 114 (ESE) ptly cldy none 00:00 50 30 23 122 (ESE) ptly cldy none 01:00 50 30 19 137 (SE) ptly cldy none 02:00 49 30 19 150 (SSE) ptly cldy none 03:00 50 30 19 170 (S) 3995 mstly clr none 04:00 47 30 19 152 (SSE) ptly cldy humid 05:00 46 29 14 170 (S) ptly cldy humid Note: the wind was coming from the azimuth listed.
