We were able to open up shortly before UW03's time ended, but they were still able to get some data. The clouds improved for a few hours before it nearly completely clouded over near dawn. The seeing was never that great. During NA01's calibrations on Kosmos, around 01:45 am, the calibration stage wouldn't changed from Moving. I was not able to move it in/out and incorrectly attempted to address the issue, resulting in a loss of connection to the ieb. A PR was filed (PR 2067) and I added some information to the wiki to try and keep this from happening again. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- NA01 kosmos I/U 01:48 01:59 cal stage stopped moving ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 21:53 arctic 408( 734) 115 55 2.3 1.5 2.6 2.3 1.9 sdss-r 1.94 22:24 tcamera 424( 881) -20 61 2.0 1.2 2.3 1.8 1.7 Ks 1.07 00:33 kosmos 424( 653) 110 52 0.9 0.5 1.5 0.7 0.8 -- 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 39 16 13 263 (W) 439 cloudy none 17:00 38 16 18 274 (W) 345 cloudy none 18:00 37 14 16 271 (W) 246 cloudy none 19:00 36 14 17 274 (W) 235 cloudy none 20:00 36 15 16 272 (W) 291 mstly cldy none 21:00 36 15 15 291 (WNW) 306 ptly cldy none 22:00 36 15 14 265 (W) 341 ptly cldy none 23:00 35 15 19 296 (WNW) 343 mstly clr none 00:00 34 15 19 318 (NW) 256 mstly clr none 01:00 34 15 15 324 (NW) 234 mstly clr none 02:00 33 14 5 349 (N) 209 clear none 03:00 33 14 12 14 (NNE) 234 clear none 04:00 32 13 8 3 (N) 206 ptly cldy none 05:00 30 15 10 83 (E) 279 mstly cldy none 06:00 30 16 3 108 (ESE) 283 cloudy none Note: the wind was coming from the azimuth listed.
