The night started clear and breezy. Seeing was good (~1"). Closed at 21:25 due to incoming rain. Clouds became thick so it wasn't possible to observe. I reopened at 23:55 when the clouds cleared. I had to close again at 02:43 due to high wind and blowing snow. No problems tonight. ------- 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 -------------------------------------------------------------------------- 17:59 NICFPS 652( 533) 163 75 -3.6 -2.3 -2.2 -2.0 -2.9 Ks 1.03 01:03 ecamera 669(-1022) 5 49 -2.2 -2.9 -2.7 -2.6 -2.5 ND1 0.90 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 26 8 5 350 (N) 53 mstly clr none 17:00 26 4 7 355 (N) 42 mstly clr none 18:00 26 4 13 10 (N) 40 ptly cldy none 19:00 27 6 17 7 (N) 41 ptly cldy none 20:00 26 7 15 341 (NNW) 36 mstly cldy none 21:00 27 8 12 353 (N) 58 mstly clr none 22:00 27 8 8 39 (NE) 56 mstly clr none 23:00 27 6 2 329 (NNW) 31 mstly clr none 00:00 29 1 10 344 (NNW) 43 clear none 01:00 28 6 15 337 (NNW) 31 clear none 02:00 28 11 11 357 (N) 28 clear none 03:00 27 12 9 3 (N) 60 clear none 04:00 27 16 21 16 (NNE) 61 clear none 05:00 27 17 16 357 (N) 28 clear none Note: the wind was coming from the azimuth listed.
