At dusk, we were able to get sky flats and stay on-sky for only 18 minutes before the humidity became too high. Re-opened a bit after the start of B Half and stayed on-sky until dawn. Restarted Skywatch software. Echelle observer noted having issues tonight with the echelle mirror sky command failing when he ran his ThAr script (more frequently tonight than typically): Errors are: Failed: echelle mirror sky failed: exceptions.RuntimeError: [Calibration Mirror Move Error! :: Mirror not fully out of beam path] mirror sky failed: exceptions.RuntimeError: [Calibration Mirror Move Error! :: Mirror not fully out of beam path] When observer executed the commands directly in the Echelle window, the action succeeds. No other issues. ------- 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 -------------------------------------------------------------------------- 18:57 arctic 347( 578) 104 80 -5.9 -4.0 -4.5 -4.1 -4.4 Semrock 2.61 01:53 ecamera 451( -523) -3 54 -5.2 -6.0 -4.8 -6.0 -5.6 ND4 0.86 ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 26 14 13 209 (SSW) 650 mstly clr none 17:00 25 17 12 202 (SSW) clear none 18:00 22 17 9 185 (S) clear humid 19:00 22 17 9 218 (SW) clear humid 20:00 21 18 14 183 (S) mstly clr humid 21:00 21 18 16 220 (SW) ptly cldy humid 22:00 22 19 12 215 (SW) mstly clr humid 23:00 21 19 11 232 (SW) clear humid 00:00 22 16 11 235 (SW) clear humid 01:00 22 17 14 235 (SW) clear humid 02:00 23 14 7 270 (W) mstly clr none 03:00 23 14 10 269 (W) mstly clr none 04:00 21 14 8 250 (WSW) clear none 05:00 23 14 8 263 (W) clear none 06:00 22 14 8 316 (NW) clear none Note: the wind was coming from the azimuth listed.
