The telescope did not move. Power cycle and another axis init fixed the issue. Clouds and nearby radar kept us closed at the start of the night. We finally opened at 22:00, seeing was pretty good when I focused but deteriorated during the next hour as the wind came at us out of the east. Seeing improved later in the night. No telescope 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 -------------------------------------------------------------------------- 22:00 ecamera 286( 302) 64 82 14.2 15.4 15.1 15.2 14.4 ND2 0.82 23:08 ecamera 351( 313) 196 48 13.2 13.9 14.2 13.5 13.4 ND2 1.40 04:34 tcamera 375( 1539) -7 64 13.4 13.1 13.7 13.3 13.4 Ks 0.87 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 63 42 6 257 (WSW) 818 mstly cldy none 17:00 64 41 5 222 (SW) 835 cloudy none 18:00 65 41 12 259 (W) 877 cloudy none 19:00 61 43 1 159 (SSE) 908 ptly cldy none 20:00 57 46 5 97 (E) 1006 ptly cldy none 21:00 59 42 5 98 (E) 959 ptly cldy none 22:00 57 43 6 99 (E) 893 ptly cldy none 23:00 56 42 11 91 (E) 952 mstly clr none 00:00 61 40 7 257 (WSW) 914 clear none 01:00 59 40 6 186 (S) 886 clear none 02:00 58 39 4 202 (SSW) 753 clear none 03:00 56 37 7 188 (S) 598 clear none 04:00 56 36 7 188 (S) 546 clear none 05:00 56 37 5 195 (SSW) 650 clear none 06:00 55 36 6 207 (SSW) 604 clear none Note: the wind was coming from the azimuth listed.
