There were almost no clouds in the sky, but the ones there were present were headed right for us and heavy with virga, which delayed our opening. After being on sky a couple hours, a wave of radar came at us, closing us for several hours. We were able to open up for NM08, but then the echelle started reading out all zeros at 3:26. However, I was not checking the users science exposures and the user didn't realize the issue until 06:00. I was able to fix the issue but they did lose several hours of data. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- NM08 Echelle I/S 03:26 06:02 Echelle reading all zeros ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:14 tcamera 335( 799) 8 62 10.0 5.6 5.8 5.7 4.8 KS 1.00 19:53 kosmos 487( 711) 25 72 10.0 4.9 5.3 4.8 4.7 -- 1.22 02:10 ecamera 411( -485) -116 65 10.0 3.3 3.8 3.5 3.5 ND2 1.02 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 9 241 (WSW) 357 ptly cldy none 17:00 6 186 (S) 415 ptly cldy none 18:00 10 179 (S) 517 mstly clr none 19:00 17 153 (SSE) 527 mstly clr none 20:00 17 132 (SE) 637 mstly clr none 21:00 17 126 (SE) 544 mstly cldy none 22:00 20 124 (SE) 531 mstly cldy none 23:00 21 119 (ESE) 521 mstly cldy lt rain 00:00 18 120 (ESE) 584 mstly cldy none 01:00 16 119 (ESE) 574 mstly cldy none 02:00 19 121 (ESE) 662 mstly cldy none 03:00 22 132 (SE) 832 mstly clr none 04:00 22 146 (SE) 1216 mstly clr none 05:00 19 151 (SSE) 1306 ptly cldy none 06:00 13 170 (S) 1428 ptly cldy none Note: the wind was coming from the azimuth listed.
