Lots of green on the radar. We stayed closed all night. Dataq was frozen and had to be restarted. KOSMOS disperser wheel stuck at "moving" going from blue to red at 0 rotation during cals (timestamp 2023-09-13 06:53:43). Fixed by moving wheel by hand and doing kosmos status robotics. Did a few more tests and found out that the wheel happily recovers upon issuing 'kosmos status robotics' only when the disperser position matches up with the last commanded move before the error, otherwise it gives a "waiting for previous ieb status command to complete" error. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp F Dewp F MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 49 50 6 266 (W) cloudy lt rain 17:00 50 50 7 265 (W) cloudy lt rain 18:00 50 51 6 271 (W) cloudy humid 19:00 51 46 15 332 (NNW) ptly cldy humid 20:00 52 47 14 296 (WNW) mstly cldy rain 21:00 52 48 6 272 (W) cloudy rain 22:00 52 48 11 272 (W) cloudy fog 23:00 50 51 11 272 (W) cloudy rain 00:00 50 51 6 263 (W) cloudy fog 01:00 51 50 8 264 (W) cloudy fog 02:00 51 50 6 264 (W) cloudy fog 03:00 50 50 8 227 (SW) cloudy fog 04:00 50 51 8 264 (W) cloudy rain Note: the wind was coming from the azimuth listed.
