Upon examination 4 looked fine but the last one (#5) looked different. See Q1NM04/UT220129/KOSMOS_Bias.000x.fits Dome temps was -3.8C We did have several more instances of the sticky shutter while guiding. It was a pain at times but we slugged through. My 2nd observers targets were all setting, and their other targets had not rose high enough yet, so they donated the remainder of their time to the next program tonight. I notified the 3rd observer to log in early. My TUI became non-responsive to selecting any menu items around 23:25, restarting TUI fixed the issue. No issues 2nd half. ------- 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 -------------------------------------------------------------------------- 17:43 tcamera 526( 928) 111 73 -3.2 0.2 -0.4 0.4 0.2 Ks 1.02 19:32 kosmos 185( 283) 154 67 -3.8 -2.1 -2.8 -3.8 -3.2 -- 1.98 23:39 dcamera 654( 587) 120 59 -1.8 -2.1 -2.6 -2.8 -2.4 -- 1.18 04:28 dcamera 354( 313) -16 63 -1.7 -1.5 -1.5 -2.6 -2.0 -- 1.30 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 27 14 2 184 (S) 987 clear none 17:00 26 13 1 221 (SW) 1007 clear none 18:00 27 9 3 124 (SE) 457 clear none 19:00 25 9 1 208 (SSW) 242 clear none 20:00 26 -2 17 78 (ENE) 184 clear none 21:00 26 -14 16 81 (E) 154 clear none 22:00 26 -8 11 92 (E) 143 clear none 23:00 28 -17 9 133 (SE) 87 clear none 00:00 29 -21 9 136 (SE) 13 clear none 01:00 30 -21 7 113 (ESE) 10 clear none 02:00 31 -22 4 173 (S) 7 clear none 03:00 30 -24 4 172 (S) 9 mstly clr none 04:00 30 -22 2 187 (S) 10 ptly cldy none 05:00 30 -21 2 224 (SW) 18 clear none 06:00 29 -23 2 52 (NE) 18 clear none Note: the wind was coming from the azimuth listed.
