First half was generally quiet, with fair seeing due to southeast winds. 2nd Half Observing Specialist: R.McMillan Second half started out peacefully enough, with clear weather and good to moderate seeing. Nicole got three exposures on her target, and I was able to observe several lens targets. Around 03:00 the humidity started to rise and clouds tickled the horizon. I closed at 03:30 due to humidity. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEGDFVO) TI/SHU START FINISH DESCRIPTION ----------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Air/Truss Wind Time Instrument Focus Az El Temp-C Dir MPH filt FWHM --------------------------------------------------------------------- 19:51 GrIm2(f/5) -100(1057) 221 79 6.8/9.1 137 18 K 0.82 19:52 NA2gdr -1922(46077)222 79 6.8/9.1 137 18 R 0.97 00:24 DISslit 50(1095) -15957 5.7/5.5 146 17 - 1.27 01:39 SPIcam 25(1269) -42 42 5.4/5.2 171 14 r' 1.07 01:41 NA2gdr 1098(50098) -42 41 5.6/5.2 175 14 R 1.31 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:01 50 -5 10 125 (SE) 532 Clear none 17:01 49 0 16 147 (SSE) 612 Clear none 18:01 46 4 19 136 (SE) 672 Clear none 19:01 44 7 19 127 (SE) 639 Clear none 20:01 45 9 16 135 (SE) 648 Clear none 21:01 44 8 16 142 (SE) 667 Clear none 22:01 44 14 17 147 (SSE) 636 Clear none 23:01 43 17 20 135 (SE) 676 Clear none 00:01 42 15 18 145 (SE) 703 Clear none 01:01 42 16 15 148 (SSE) 676 clear none 02:01 42 20 12 179 (S) 697 clear none 03:01 41 34 12 178 (S) 616 ptly cldy none 04:01 41 36 9 181 (S) 650 ptly cldy none 05:01 39 36 7 186 (S) 629 ptly cldy none Note: the wind was coming from the azimuth listed.
