Wow...the fire hose of information. But we were able to get on sky! The weather was not good enough to fire the laser, sadly. We had clouds, high dust, high winds, more high dust. However, we did fire the laser with the dome closed. During the strong winds, I closed just a minute too late and there was a collision and I needed to push the telescope away from the dome. We were not able to open for engineering and I ran some echelle tests but was not able to complete them. The dust and wind improved by 00:30 and, since I wasn't able to run any engineering on sky with the little time I had left, I donated the remaining time to NM07. Seeing was pretty bad. The mote light came on around midnight and I PR'd it and notified Ben and Bill. ------- 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 -------------------------------------------------------------------------- 00:30 kosmos 689( 1007) 240 53 10.0 6.7 8.3 6.6 5.0 -- 2.45 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 17 253 (WSW) 2575 ptly cldy none 17:00 25 267 (W) 2726 ptly cldy none 18:00 21 240 (WSW) 2946 ptly cldy none 19:00 28 256 (WSW) 2632 ptly cldy none 20:00 32 268 (W) 2827 mstly cldy none 21:00 22 269 (W) 2605 mstly cldy dust 22:00 10 330 (NNW) 7722 mstly clr dust 23:00 16 317 (NW) 3048 clear dust 00:00 8 32 (NNE) 2999 clear none 01:00 17 53 (NE) 2585 clear none 02:00 5 36 (NE) 2914 clear none 03:00 9 7 (N) 2837 clear none 04:00 9 43 (NE) 2705 mstly clr none 05:00 6 315 (NW) 3131 ptly cldy none 06:00 7 66 (ENE) 2197 mstly clr none Note: the wind was coming from the azimuth listed.
