Bill had me power cycle it using the email instructions he sent earlier in the day. This fixed it. Clouds formed over us around 04:20 with the approaching cold front. Completely swamped us by 04:30 with a big radar return approaching. I noticed when I closed that the Dataq again was frozen. I power cycled it and it came back to life. From the looks of things there was little hope of re-opening this late in the night so we gave up early. No telescope issues 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 -------------------------------------------------------------------------- 17:13 APOLLO 325( 1603) 48 49 2.7 4.0 4.1 3.5 3.1 -- 1.10 18:21 kosmos 300( 686) 5 59 2.4 1.8 3.2 2.4 2.4 -- 1.03 22:53 tcamera 252( 795) 129 54 1.2 -0.2 0.3 -0.6 0.1 Ks 1.25 00:28 NICFPS 225( 981) 90 66 -1.4 -0.9 -0.6 -1.4 -1.6 Ks 1.30 00:34 NA2gdr 11002(49002) 89 68 -1.4 -0.9 -0.7 -1.6 -1.7 Clear 2.14 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 39 14 11 275 (W) 569 clear none 17:00 38 13 13 277 (W) 636 clear none 18:00 37 14 11 265 (W) 939 clear none 19:00 35 14 14 235 (SW) 3696 clear none 20:00 36 14 13 262 (W) 3567 clear none 21:00 35 14 15 270 (W) 1577 clear none 22:00 32 14 6 287 (WNW) 1735 clear none 23:00 33 14 8 329 (NNW) 1211 clear none 00:00 31 9 6 15 (NNE) 1024 clear none 01:00 29 8 6 21 (NNE) 727 clear none 02:00 27 10 13 9 (N) 1004 clear none 03:00 24 12 11 44 (NE) 743 clear none 04:00 22 8 20 25 (NNE) 489 cloudy none Note: the wind was coming from the azimuth listed.
