Coughlin Weather started off with some real thin clouds, but they cleared out after sunset and it turned nearly photometric around 22:00 for most of the rest of the night, with seeing just under 1". I closed just before twilight at 04:30 with clouds quickly encroaching with radar returns. No problems. ------- 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 ----------------------------------------------------------------- 20:42 dis-slit 120( 634) 157 49 16.6 18.3 17.0 16.7 16.3 1.50 22:57 dis-slit 108( 512) 254 63 16.8 16.4 16.5 15.4 16.2 0.90 01:10 ECHELLE -105( -412) 353 52 16.6 15.9 16.3 15.2 16.0 ND1 0.80 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------- 16:00 68 27 18 266 (W) 2336 ptly cldy none 17:00 70 28 16 248 (WSW) 1729 ptly cldy none 18:00 68 27 17 264 (W) 1732 mstly clr none 19:00 67 27 18 267 (W) 1695 mstly clr none 20:00 63 24 13 222 (SW) 1512 mstly clr none 21:00 62 23 12 216 (SW) 1371 mstly clr none 22:00 62 23 8 189 (S) 1056 clear none 23:00 62 24 11 187 (S) 955 clear none 00:00 62 25 16 214 (SW) 895 clear none 01:00 62 25 9 263 (W) 910 mstly clr none 02:00 60 20 5 327 (NNW) 906 clear none 03:00 60 20 8 276 (W) 798 mstly clr none 04:00 60 19 4 259 (W) 638 ptly cldy none 05:00 60 19 6 264 (W) 633 cloudy none Note: the wind was coming from the azimuth listed.
