The Apollo laser wasn't operational and AP01 donated 30 min of their time to WY04. Things were pretty humid most of the night! We were skating borderline closure conditions for nearly the whole night before things started drying up around 5am. Given that, the seeing was surprising good! Reaching down to 1" at one point. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- AP01 A I/U 18:00 18:30 The laser was not responding ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 18:41 tcamera 589( 499) 266 77 -8.5 -5.0 -4.5 -5.2 -7.4 MK-s 1.10 19:07 tcamera 422( 282) 119 70 -8.5 -6.1 -5.4 -6.5 -8.0 MK-s 1.31 20:58 tcamera 395( 165) 117 69 -8.1 -8.1 -7.2 -8.3 -8.1 MK-s 1.04 00:24 dcamera 498( -162) -87 73 -8.2 -9.0 -8.3 -9.0 -8.6 -- 1.12 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 17 14 10 302 (WNW) ptly cldy humid 17:00 17 13 4 279 (W) mstly clr humid 18:00 17 11 2 329 (NNW) clear humid 19:00 17 8 6 25 (NNE) clear humid 20:00 17 8 7 9 (N) 157 clear humid 21:00 17 11 12 2 (N) clear humid 22:00 17 12 6 344 (NNW) clear humid 23:00 17 11 16 333 (NNW) clear humid 00:00 17 11 13 316 (NW) clear humid 01:00 18 7 10 345 (NNW) clear humid 02:00 18 8 19 325 (NW) 154 clear humid 03:00 18 5 11 357 (N) 227 clear humid 04:00 18 3 18 345 (NNW) 268 clear humid 05:00 19 -1 12 356 (N) 576 clear none Note: the wind was coming from the azimuth listed.
