I suspect it knew Bill was looking at it. I tried jiggling the umbilical during fills but images were still good. The night started with high winds (43 mph) and dust, which kept us closed until 22:07. However, the seeing wasn't quite the train wreck I was expecting! We even got near 1" towards the end of the night. Dataq got really slow all of a sudden at CU02 switchover and I needed to power cycle the Mac mini. I mounted arctic once the last observer was done with their cals and took some test exposures. Everything looked good... 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 -------------------------------------------------------------------------- 22:24 ecamera 402( -275) 122 83 3.7 3.9 5.1 3.6 3.6 ND2 1.76 00:10 ecamera 508( -259) -22 50 2.9 1.6 3.2 2.4 2.4 ND2 1.37 04:44 tcamera 473( 873) 104 61 0.1 0.0 0.8 0.1 0.1 Ks 1.08 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 47 4 25 217 (SW) 4090 clear dust 17:00 44 3 26 216 (SW) 3518 clear dust 18:00 42 2 34 209 (SSW) 5530 clear dust 19:00 41 1 24 241 (WSW) 10821 clear dust 20:00 40 0 22 246 (WSW) 10712 clear dust 21:00 39 5 21 248 (WSW) 7205 mstly cldy dust 22:00 39 6 26 242 (WSW) 2515 mstly cldy none 23:00 38 5 18 250 (WSW) 1468 mstly cldy none 00:00 37 5 22 229 (SW) 1534 ptly cldy none 01:00 37 5 24 226 (SW) 1071 clear none 02:00 36 7 26 229 (SW) 1046 clear none 03:00 33 9 24 229 (SW) 1034 clear none 04:00 34 11 25 233 (SW) 889 clear none 05:00 32 13 25 244 (WSW) 1506 clear none 06:00 32 13 27 236 (SW) 1274 clear none Note: the wind was coming from the azimuth listed.
