The finished a little early due to the clouds messing with the time they needed for a set of observations at the end, not enoough time to finish a sequence, not clouds. 00:55 Arctic filter change g (pos #2) to r (pos #4)failed, rot @ 165 deg. Needed to rot 0 and home. 01:15 Arctic filter change i to r failed rot @ 153 deg. Needed to rot 0 and home Lots of clouds to contend with tonight but we stayed open thru it all. No telescope problems other than the Arctic filter wheel noted above. ------- 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 -------------------------------------------------------------------------- 17:49 dcamera 510( 485) 267 59 -2.2 -1.2 -1.1 -1.9 -2.2 -- 1.43 18:50 dcamera 510( 477) 231 50 -1.9 -1.5 -1.6 -2.3 -2.1 -- 1.70 22:34 tcamera 412( 712) 249 71 -2.6 -2.0 -2.3 -2.9 -2.8 Ks 1.02 00:14 arctic 483( 576) 316 48 -3.4 -3.5 -3.0 -3.4 -3.3 SDSS_g 1.27 00:16 NA2gdr -157(36842) 316 48 -3.4 -3.5 -2.9 -3.5 -3.4 clear 1.44 02:56 dcamera 565( 367) 130 72 -4.8 -4.7 -4.2 -4.6 -4.6 -- 1.80 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 32 9 27 266 (W) 253 ptly cldy none 17:00 29 8 14 264 (W) 256 mstly cldy none 18:00 28 8 15 267 (W) 221 mstly cldy none 19:00 29 9 14 262 (W) 211 mstly cldy none 20:00 28 10 16 265 (W) 207 mstly cldy none 21:00 28 11 10 266 (W) 225 ptly cldy none 22:00 28 11 17 263 (W) 238 ptly cldy none 23:00 27 12 14 255 (WSW) 248 mstly clr none 00:00 26 12 15 265 (W) 245 mstly clr none 01:00 26 11 17 275 (W) 243 ptly cldy none 02:00 25 11 24 269 (W) 278 mstly cldy none 03:00 24 14 23 279 (W) 358 mstly cldy none 04:00 22 14 21 281 (W) 359 mstly cldy none 05:00 23 13 32 271 (W) 292 cloudy none 06:00 21 14 16 266 (W) 405 cloudy none Note: the wind was coming from the azimuth listed.
