Rebooted the slitviewer computer. 2nd half Observing Specialist: B.Ketzeback Night went fine. At 05:10 dust levels spiked and I changed fan configurations to remain open. Levels bounced a while about the 2000 particles/0.1 cu. ft level until the end of the night but never reached the closure limit. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- UC10 E I/S 20:14 20:25 Echelle SV crash ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 19:17 SPIcam -180(1256) 126 47 12.1/16.1 39 10 r' 1.25 19:21 NA2gdr 4321(53321) 127 48 12.3/16.1 14 12 R 1.29 20:10 Echelle -200(80) 159 74 12.2/16.1 13 11 ND2 0.96 22:05 DISSlit 140(1010) -147 76 11.9/12.3 282 8 none 0.86 22:12 NA2gdr 483(44483) -142 75 12.0/12.2 272 7 R 0.82 -------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 58 14 6 345 (NNW) 414 Clear none 17:01 58 14 11 311 (NW) 471 Clear none 18:01 56 13 0 235 (SW) 501 Clear none 19:01 54 13 6 12 (NNE) 555 Clear none 20:01 54 12 11 25 (NNE) 476 Clear none 21:01 55 14 6 11 (N) 546 Clear none 22:01 54 14 5 276 (W) 533 Clear none 23:01 53 14 6 292 (WNW) 485 Clear none 00:01 53 14 7 280 (W) 484 prtly cldy none 01:01 52 15 4 271 (W) 631 clear none 02:01 51 17 0 184 (S) 991 clear none 03:01 50 17 5 278 (W) 1017 clear none 04:01 49 16 4 238 (WSW) 1020 clear none 05:01 48 18 0 191 (S) 1026 clear none 06:01 46 22 5 245 (WSW) 1982 clear none Note: the wind was coming from the azimuth listed.
