              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend,C.Gray
At checkout, gcam needed startNubs and NICFPS needed an expose init.
Reset the ARCTIC filter wheel controller at changeover after getting error: "Sub-command(s) failed: move 1: filter wheel is moving"
Completely overcast all night with radar, fog, and snow. We were unable to open.
Dome is parked south because there was some snow accumulation.
Temperature was 2C with 72% humidity before sunset. We hit 90% humidity by 22:00. Temps dropped to about -3C by morning and humidity up to 95%.
