              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Windy and dusty before sunset. Dust calmed down around 19:00, wind came down almost enough for a little while but we got totally clouded out too, and then the wind speeds picked back up. We maxed out at a little over 50mph gusts. We haven't gotten any snow yet as of 05:30 but we weren't able to open at all.
Temperatures were 4.5C in the afternoon and fell to -2.2C by morning; humidity rose from 20 to 40%.
No telescope or instrument problems.
Winds are mostly SW so I left the dome parked East.
