              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
From about 14:00 to 20:00 we had DNS issues onsite. Big thanks to Shane and everyone who fixed things! This is also why the first few hours of the Weather Log are missing data.
We couldn't open during this time anyway due to mirror temperatures and wind speeds too high given the limitations we have tonight due to ice and snow remaining on the dome, so time lost is marked as due to weather.
A little after 02:00 the wind speeds came down under 15mph and stayed there, so we opened up! We closed up at the end of the night for twilight and cals.
Dome is parked south.
