(see checkout images). Observer noticed this as well.

I focused TSPEC on the fly during the night. The seeing was between 1 - 1.5 arc sec. I closed at 02:26 due to humidity. Re-opened at 03:06. Closed again at 04:00 for humidity. Opened 05:00. Humidity started rising as soon as I opened but we stayed open as the humidity flirted with the closure limits. ------- 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 -------------------------------------------------------------------------- 18:06 TSPEC 816( 344) 126 66 -1.5 0.4 -0.9 0.8 -1.0 Ks 1.00 18:56 TSPEC 591( 77) 135 73 -1.1 -0.3 -0.9 -0.3 -1.0 Ks 1.10 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 30 20 1 234 (SW) 2327 ptly cldy none 17:00 27 19 0 275 (W) 2407 ptly cldy none 18:00 28 19 2 160 (SSE) 1645 ptly cldy none 19:00 31 18 7 181 (S) 1581 ptly cldy none 20:00 29 18 10 166 (SSE) 1826 clear none 21:00 28 20 12 151 (SSE) 2597 clear none 22:00 28 20 8 169 (S) 2876 clear none 23:00 28 20 7 166 (SSE) 2582 clear none 00:00 28 20 8 185 (S) 3673 clear none 01:00 29 20 11 179 (S) 3426 clear none 02:00 26 22 12 161 (SSE) 3884 clear humid 03:00 28 21 11 182 (S) 3360 clear humid 04:00 27 24 13 174 (S) 4638 clear humid 05:00 29 22 10 177 (S) 3094 clear humid 06:00 27 22 6 186 (S) 3247 clear none Note: the wind was coming from the azimuth listed.
