The seeing was terrible, and hazy clouds lingered, so this program could not take data for the last 2 hours. Struggling through the clouds most of the night, we managed to stay open. No technical problems. ------- FAILURE LOG ------- PROG INST FAILURE MODE TIME (SEDFNVOG) TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 19:15 ecamera 372( -784) 260 65 3.7 4.7 4.8 4.4 3.7 ND2 1.60 20:31 ecamera 357( -859) 196 60 3.1 3.5 3.8 3.3 3.0 ND2 1.35 00:19 dcamera 230( 8) 307 44 2.5 2.0 2.4 2.1 2.2 -- 2.93 02:35 tcamera 453( 413) -15 56 2.6 2.0 2.4 2.1 2.2 -- 1.70 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 43 29 4 217 (SW) 90 ptly cldy none 17:00 39 33 1 196 (SSW) 107 mstly clr none 18:00 39 33 9 109 (ESE) 116 mstly clr none 19:00 38 30 10 100 (E) 98 clear none 20:00 37 30 13 86 (E) 111 ptly cldy none 21:00 37 29 13 86 (E) 123 mstly cldy none 22:00 36 28 14 89 (E) 104 mstly cldy none 23:00 36 27 19 113 (ESE) 130 mstly cldy none 00:00 36 27 15 86 (E) 143 ptly cldy none 01:00 36 27 18 114 (ESE) 136 mstly cldy none 02:00 37 27 24 122 (ESE) 172 mstly cldy none 03:00 36 25 20 111 (ESE) 126 mstly cldy none 04:00 36 24 20 116 (ESE) 143 mstly cldy none 05:00 37 24 27 130 (SE) 155 ptly cldy none 06:00 36 24 23 120 (ESE) 147 ptly cldy none Note: the wind was coming from the azimuth listed.
