I let the observers know so they wouldn't have to stay up. Clouds, Humidity, and more snow during the night. 6+ additional inches. GIFS temp alarm triggered. No data read. I checked the front panel on the intermediate level and the temps were fine. I ran the snow program all night and parked the telescope due south when I went to bed at 06:00. 12+ inches of snow total accumulation on site as of 05:30. Dome will need to be cleared before we can open the 3.5m but probably unsafe to drive up here until the roads are cleared. ------- 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 -------------------------------------------------------------------------- ------------- WEATHER LOG ---------------- Wind Precip.or Time Temp C Dewp C MPH Direction Dust Sky Conditions ------------------------------------------------------------------ 16:00 22 21 16 235 (SW) 8154 cloudy humid 17:00 22 21 26 263 (W) 10936 cloudy humid 18:00 19 18 26 263 (W) 260 cloudy humid 19:00 19 18 16 248 (WSW) 9185 cloudy humid 20:00 19 18 15 227 (SW) 2674 cloudy humid 21:00 19 17 15 234 (SW) 530 cloudy lt snow 22:00 19 17 17 239 (WSW) 685 cloudy snow 23:00 20 18 18 266 (W) 232 cloudy snow 00:00 20 18 15 265 (W) 1312 cloudy snow 01:00 20 18 16 279 (W) 538 cloudy lt snow 02:00 21 19 19 272 (W) 584 cloudy lt snow 03:00 20 18 10 281 (W) 3125 cloudy lt snow 04:00 20 18 24 297 (WNW) 2671 cloudy snow 05:00 20 18 12 359 (N) 6898 cloudy snow Note: the wind was coming from the azimuth listed.
