It was windy again tonight, we couldn't until 20:30 when the wind gust speeds came down and hovered just under the closure limits, but they went back up again and we had to close at 22:06. NM07 got a few targets observed though! Around 02:30, gust speeds dropped from mid 40s to low 20s mph and stayed there for the rest of the night. Otherwise it was a nice clear night. When we did open for JH02, we found that the TSPEC slitviewer images were all zeroes. I had to power cycle the Leach controller and startNubs+init as per the wiki instructions for this problem, and it came back. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- JH02 TSPEC I/H 02:46 03:05 TSPEC Slitviewer images all zeros ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:36 ecamera 518( -155) 233 65 4.7 3.8 4.0 4.0 4.2 ND2 1.04 03:12 tcamera 523( 1117) 1 55 6.1 4.1 4.4 4.3 5.0 Ks 1.83 06:09 dcamera 500( 792) 79 15 6.2 4.7 5.3 4.8 5.2 -- 2.12 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 40 11 21 19 (NNE) 927 clear none 17:00 40 9 19 355 (N) 826 clear none 18:00 40 9 12 0 (N) 300 clear none 19:00 40 10 15 360 (N) 298 clear none 20:00 41 11 20 31 (NNE) 299 clear none 21:00 41 9 23 354 (N) 309 clear none 22:00 42 6 24 12 (NNE) 383 clear none 23:00 40 7 18 1 (N) 442 clear none 00:00 39 8 36 23 (NNE) 503 clear none 01:00 38 9 38 27 (NNE) 533 clear none 02:00 42 8 31 23 (NNE) 364 clear none 03:00 43 6 17 23 (NNE) 302 clear none 04:00 42 8 9 21 (NNE) 319 clear none 05:00 44 7 24 5 (N) 302 clear none 06:00 44 7 11 3 (N) 275 clear none Note: the wind was coming from the azimuth listed.
