Seeing was not good at the beginning of the night, averaging around 2" but it improved as the night went on....until the wind blew in. And it rocked us like a hurricane. While trying to slew out of the wind and to an eastern target for the start of UW06, a gust of 42mph hit and there was a motion error. We remained closed for about an hour. Clouds and wind stayed with us the rest of the night. Tspec took some good images last night but it's back to sitting in the dunce corner tonight. I took 5000 darks. ------- 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 -------------------------------------------------------------------------- 17:19 ecamera 849( -398) -36 41 4.9 5.7 6.0 5.4 4.9 clear 1.98 18:56 ecamera 849( -470) -58 26 4.0 3.7 4.3 3.8 3.8 clear 2.40 19:53 ecamera 824( -512) -40 21 4.1 3.6 4.1 3.8 4.0 clear 1.65 21:01 arctic 784( 592) 171 62 3.2 3.1 3.7 3.2 3.2 UNM-657 1.05 22:41 arctic 809( 619) 29 74 3.8 3.3 3.7 3.5 3.5 UNM-657 1.20 01:14 ecamera 779( -603) 53 47 3.0 3.1 3.5 3.3 3.2 ND3 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 43 12 18 271 (W) 361 clear none 17:00 40 14 17 271 (W) 498 clear none 18:00 40 14 14 273 (W) 461 clear none 19:00 39 17 21 270 (W) 506 clear none 20:00 38 18 16 266 (W) 540 clear none 21:00 38 17 24 271 (W) 535 clear none 22:00 38 14 27 269 (W) 420 mstly clr none 23:00 39 13 33 280 (W) 498 mstly clr none 00:00 39 18 29 274 (W) 721 ptly cldy none 01:00 38 18 33 292 (WNW) 728 ptly cldy none 02:00 38 17 19 287 (WNW) 710 mstly cldy none 03:00 38 20 22 301 (WNW) 480 mstly cldy none 04:00 38 19 19 297 (WNW) 526 mstly cldy none 05:00 38 20 17 278 (W) 396 mstly cldy none 06:00 39 20 22 294 (WNW) 327 ptly cldy none Note: the wind was coming from the azimuth listed.
