The seeing was good but the moon was casting a gradient on UW01's last hour of observing. They said they had sufficient baseline time and donated their remaining hour to UW09. I hadn't used the rotation on the arctic diffuser yet and was unclear on the steps of its use. I added a note in the wiki that after turning the rotator on you have to execute an "arctic status" in the log window. No problems tonight. ------- 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 -------------------------------------------------------------------------- 17:52 ecamera 750( 454) 177 78 10.3 11.9 10.4 11.3 11.6 Clear 1.19 18:32 ecamera 641( 291) 226 77 10.0 10.8 10.2 10.4 10.4 Clear 0.73 19:44 ecamera 479( 83) 232 59 9.9 9.6 9.8 9.3 9.6 Clear 1.10 21:48 arctic 460( 1167) 141 26 10.1 9.1 9.8 9.1 9.3 sdss-i 1.90 04:13 ecamera 461( 61) 330 76 11.8 9.7 10.1 9.5 10.2 ND3 0.72 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 58 24 12 252 (WSW) 493 mstly clr none 17:00 57 25 9 263 (W) 532 mstly clr none 18:00 53 28 9 243 (WSW) 700 mstly clr none 19:00 50 28 13 232 (SW) 790 mstly clr none 20:00 50 28 13 237 (WSW) 836 clear none 21:00 50 27 14 227 (SW) 760 clear none 22:00 50 27 10 232 (SW) 650 mstly clr none 23:00 50 28 10 222 (SW) 689 mstly clr none 00:00 50 29 6 226 (SW) 697 ptly cldy none 01:00 50 30 10 261 (W) 839 mstly clr none 02:00 50 31 8 297 (WNW) 764 ptly cldy none 03:00 51 28 8 322 (NW) 617 mstly cldy none 04:00 52 28 10 6 (N) 671 ptly cldy none 05:00 52 26 5 270 (W) 494 ptly cldy none 06:00 53 25 4 242 (WSW) 437 ptly cldy none Note: the wind was coming from the azimuth listed.
