Also TUI on obs0 disconnected at about 04:00. Otherwise telescope and instruments were fine. We had a few clouds after doing an eyepiece tour of the sky with the class, but we were open all night. ------- 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 -------------------------------------------------------------------------- 20:09 APOLLO 450( 1927) 263 47 13.8 15.7 15.6 15.1 14.2 530 0.90 23:49 kosmos 450( 1057) -163 67 13.6 13.0 13.7 13.0 13.1 -- 1.19 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 62 27 17 295 (WNW) 822 mstly clr none 17:00 59 29 12 262 (W) 738 mstly clr none 18:00 64 31 11 272 (W) 762 mstly clr none 19:00 62 30 10 278 (W) 763 mstly clr none 20:00 57 23 14 279 (W) 673 clear none 21:00 57 24 5 259 (W) 678 clear none 22:00 57 25 11 261 (W) 777 mstly clr none 23:00 57 24 9 259 (W) 772 mstly cldy none 00:00 57 24 9 262 (W) 759 mstly cldy none 01:00 56 24 9 264 (W) 817 mstly clr none 02:00 55 22 10 290 (WNW) 803 clear none 03:00 54 25 9 288 (WNW) 785 ptly cldy none 04:00 53 26 7 298 (WNW) 781 mstly clr none 05:00 54 25 2 233 (SW) 737 mstly clr none Note: the wind was coming from the azimuth listed.
