We had high winds, dust, and clouds for most of A half, though we were able to open around 23:00 and punched through the clouds. Things seemed to improve with AD02 but then turned terrible for NM03. The echelle IOL seems to be steady in the red but is declining in the blue. ------- 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 -------------------------------------------------------------------------- 22:10 dcamera 495( 919) 105 71 13.5 14.3 15.2 14.1 13.8 -- 1.33 00:29 arctic 680( 1168) 279 57 12.2 12.5 13.1 12.6 12.5 sdss-r 1.13 02:56 ecamera 480( -82) -112 80 11.8 11.7 12.2 11.9 11.8 Clear 1.12 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 63 18 32 245 (WSW) 797 mstly cldy none 17:00 62 18 26 261 (W) 870 mstly cldy none 18:00 63 18 35 252 (WSW) 995 mstly cldy none 19:00 62 17 33 251 (WSW) 1469 mstly cldy none 20:00 59 14 33 263 (W) 1666 cloudy none 21:00 58 12 17 267 (W) 7274 cloudy none 22:00 57 12 28 275 (W) 4481 cloudy none 23:00 56 12 22 283 (WNW) 3453 mstly cldy none 00:00 56 11 17 274 (W) 2508 ptly cldy none 01:00 54 11 14 265 (W) 1519 mstly clr none 02:00 54 12 17 270 (W) 1702 ptly cldy none 03:00 53 12 16 288 (WNW) 1504 mstly cldy none 04:00 53 13 18 291 (WNW) 842 cloudy none 05:00 52 18 12 264 (W) 944 ptly cldy none Note: the wind was coming from the azimuth listed.
