We delayed opening slightly due to a T-strom to our SW and clouds moving in from the E. Needed to make sure it was safe from precipitation before opening. I closed after the APOLLO run due to clouds. WY01 gave up due to the clouds around 23:40 and ceded their remaining time (cloudy that it was) to the next program. The skies cleared enough and the rain threat was low that I decided to open at 00:20. Elevated dust levels during 2nd half but they never exceeded 3300 cts. I ran the fans in "reverse" mode for the 2nd half of the night. Observer was taking echelle cals in the morning so no morning IOL. No problems tonight. ------- FAILURE LOG ------- FAILURE MODE TIME PROG INSTR TI/SHU START FINISH DESCRIPTION ---------------------------------------------------------------------- ---------------- FOCUS LOG --------------- Time Instrument Focus Az El Temp Strc Prim Sec Air filt FWHM -------------------------------------------------------------------------- 20:31 APOLLO 300( 2240) -49 31 18.6 21.1 20.7 20.9 20.2 530 2.50 00:33 ecamera 341( 345) 86 69 17.7 18.2 18.8 18.2 18.1 ND2 0.97 02:56 ecamera 601( 544) 235 46 15.8 16.6 18.3 16.4 16.8 Clear 0.99 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 66 50 9 83 (E) 1460 ptly cldy none 17:00 72 47 5 213 (SSW) 1530 ptly cldy none 18:00 74 49 9 218 (SW) 1497 ptly cldy none 19:00 67 46 8 89 (E) 1829 ptly cldy none 20:00 63 46 8 118 (ESE) 1868 mstly cldy none 21:00 67 42 7 133 (SE) 2822 mstly cldy none 22:00 67 42 4 183 (S) 2484 cloudy none 23:00 66 43 2 189 (S) 2435 mstly cldy none 00:00 64 43 7 101 (E) 3195 ptly cldy dust 01:00 63 44 7 95 (E) 2917 ptly cldy dust 02:00 62 43 10 114 (ESE) 3185 mstly clr dust 03:00 60 44 6 113 (ESE) 2847 mstly clr dust 04:00 63 40 9 157 (SSE) 3240 mstly clr dust 05:00 61 41 10 147 (SSE) 3107 ptly cldy none Note: the wind was coming from the azimuth listed.
