              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Due to snow on the dome we had limits of 15 mph winds and mirrors below freezing. It was pretty warm today and even after sunset ambient temps were still hovering around 0C, so it took a while for the mirrors to cool off. By that time winds had picked up a little bit.
We opened up after midnight when the mirrors had finally cooled off and the wind dropped back down. Seeing was pretty good and we were able to take advantage of the clear sky for the rest of the night!
