However, we were able to open at 20:30, which I was not expecting! There was a very fun conversation with UW02 who argued the point for DD funds for a site sauna. We struggled with clouds but the seeing was good until the wind shifted to the north and then the seeing tanked. The clouds were a problem enough for FG01 that we closed for about an hour to take calibrations until things improved. Some of the readout noise issues were seen with kosmos tonight. I added it to PR 2118. ------- 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 414( -457) -44 77 5.0 4.0 4.1 3.9 4.3 ND2 0.76 21:34 arctic 428( 674) -10 53 5.0 4.1 4.5 4.0 4.6 sdss-r 0.97 00:29 kosmos 452( 649) 127 66 5.2 4.2 4.9 4.4 4.2 -- 1.63 03:54 kosmos 384( 462) -9 68 3.4 1.7 3.2 2.7 2.7 -- 1.51 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 38 35 12 216 (SW) 470 mstly cldy fog 17:00 38 15 11 211 (SSW) cloudy fog 18:00 38 16 9 221 (SW) 267 cloudy fog 19:00 41 -1 10 237 (WSW) 87 mstly cldy none 20:00 40 -7 12 261 (W) 75 mstly clr none 21:00 40 -12 8 254 (WSW) 112 mstly clr none 22:00 42 -17 8 227 (SW) 135 ptly cldy none 23:00 41 -24 6 266 (W) 166 ptly cldy none 00:00 40 -10 5 255 (WSW) 173 mstly cldy none 01:00 39 -5 4 291 (WNW) 177 mstly cldy none 02:00 38 -8 3 323 (NW) 163 ptly cldy none 03:00 38 -13 8 273 (W) 152 ptly cldy none 04:00 38 -4 5 275 (W) 166 ptly cldy none 05:00 39 -7 5 277 (W) 130 mstly clr none 06:00 40 -10 5 265 (W) 94 mstly clr none Note: the wind was coming from the azimuth listed.
