It needed a nicfps expose init but then everything was fine. Open. Close. Open. Close. The theme of the night. We started the evening with clouds and radar near by. Things cleared over us but there was still radar nearby. We were able to stay open all of 30 min before closing again for an hour and a half. Then closed for a few more hours while there was light rain. Then clearing and re-opening. Then cloudy and closing. The good news is that when we were open we had good seeing! In filling out the focus log, I noticed that the ecam time stamp did not match the actual recorded time, ecam is behind one hour. I didn't figure this out until dawn and will send a PR tomorrow. ------- 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 -------------------------------------------------------------------------- 20:26 ecamera 292( 221) -11 64 19.5 23.0 22.5 22.8 20.2 Clear 1.52 22:04 ecamera 205( -5) 207 73 18.1 20.2 20.3 19.7 18.6 Clear 0.82 04:07 ecamera 338( -35) 238 55 15.8 16.5 17.0 16.6 15.8 ND1 1.00 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 74 40 9 268 (W) 864 ptly cldy none 17:00 72 40 6 271 (W) 809 ptly cldy none 18:00 73 37 13 237 (WSW) 711 mstly cldy none 19:00 69 39 6 258 (WSW) 701 mstly cldy none 20:00 68 40 1 200 (SSW) 714 ptly cldy none 21:00 65 42 10 115 (ESE) 823 mstly clr none 22:00 65 43 9 132 (SE) 782 mstly clr none 23:00 66 43 8 131 (SE) 807 mstly cldy lt rain 00:00 63 42 7 17 (NNE) 786 cloudy none 01:00 61 31 12 9 (N) 736 cloudy none 02:00 63 30 11 8 (N) 631 mstly cldy none 03:00 63 30 12 25 (NNE) 552 mstly clr none 04:00 60 28 18 15 (NNE) 538 ptly cldy none 05:00 61 28 17 25 (NNE) 511 mstly cldy none 06:00 62 32 11 33 (NNE) 543 mstly cldy none Note: the wind was coming from the azimuth listed.
