Az slew tests were skipped due to wind. Due to the shutdown tomorrow, it was decided that limits would not be pushed, and we remained closed at sunset due to winds > 35mph (I was not taking any chances tonight, given the impending shutdown). We finally opened at 20:15 as winds died down. Skies were partly cloudy and the seeing was bad. Winds picked up again around 22:30. We shutdown at 23:07 due to winds. We were able to open again at 00:33 when the winds died down. Seeing was still bad. We stayed open until dawn. ------- 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 -------------------------------------------------------------------------- 20:16 tcamera 580( 1076) 116 56 5.9 7.2 8.2 7.0 5.8 - 2.08 21:06 ecamera 763( -87) 19 55 4.7 6.3 7.8 5.6 5.1 clear 2.55 22:02 ecamera 885( -22) 84 38 4.2 4.8 6.5 4.3 4.3 ND1 3.12 01:19 arctic 838( 889) 236 67 2.1 2.2 5.0 2.4 2.4 JC-B 2.05 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 47 14 33 254 (WSW) 753 mstly cldy none 17:00 48 15 26 263 (W) 707 mstly cldy none 18:00 45 14 21 260 (W) 1470 ptly cldy none 19:00 44 15 26 251 (WSW) 678 ptly cldy none 20:00 43 15 21 262 (W) 658 ptly cldy none 21:00 41 15 19 272 (W) 948 mstly clr none 22:00 40 13 21 273 (W) 564 mstly clr none 23:00 39 9 22 275 (W) 371 mstly clr none 00:00 38 6 21 281 (W) 243 mstly clr none 01:00 37 7 14 269 (W) 268 mstly clr none 02:00 36 12 16 277 (W) 512 clear none 03:00 35 15 21 292 (WNW) 321 clear none 04:00 34 15 15 317 (NW) 299 clear none 05:00 33 9 12 315 (NW) 200 clear none 06:00 33 10 14 24 (NNE) 161 clear none Note: the wind was coming from the azimuth listed.
