              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Clear but windy! We closed at 22:30 due to wind gusts over the limit. Gusts stayed around 40mph for a few hours, and then came back down.
We opened back up around 02:00 with marginal humidity and terrible seeing, but the humidity never got so bad we had to close again.
No telescope or instrument problems.
