I closed the Dataq manager and re-opened. It showed both PMSS and PMSS-Spare as Not Available. I restarted the dataq on hub35m and things were recognized once again. I set the dataq up to record but didn't get the option to set the time duration for some reason when I set the file. We opened just a few minutes behind schedule due to elevated outside dust counts. Clouds started forming around 22:30 but nothing we needed to close for. I switched over to Kosmos and got the instrument focused but the clouds grew thicker and my last observer for the night never got any useful data due to the clouds. We remained open, but finally gave up around 04:25 as the clouds didn't seem thinning. ------- 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 -------------------------------------------------------------------------- 19:05 tcamera 626( 1775) 115 41 10.6 12.4 11.9 12.3 11.0 Ks 1.27 01:30 khigh 287( 1027) -26 56 8.5 8.2 8.8 8.2 8.3 - 1.05 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 58 35 28 236 (SW) 7766 clear dust 17:00 57 34 29 239 (WSW) 4396 clear dust 18:00 54 32 19 282 (WNW) 6029 clear dust 19:00 51 34 20 267 (W) 3131 clear dust 20:00 50 31 17 266 (W) 2435 clear none 21:00 49 27 15 263 (W) 1411 clear none 22:00 48 23 17 290 (WNW) 1696 mstly clr none 23:00 48 21 17 321 (NW) 1364 ptly cldy none 00:00 49 19 17 279 (W) 1370 ptly cldy none 01:00 48 24 23 298 (WNW) 1369 mstly cldy none 02:00 47 26 17 317 (NW) 1574 cloudy none 03:00 46 24 16 299 (WNW) 1343 cloudy none 04:00 46 29 18 316 (NW) 1396 cloudy none 05:00 46 30 15 302 (WNW) 1602 cloudy none Note: the wind was coming from the azimuth listed.
