                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 We opened about 35 mins after sunset due to humidity near closure limit.
 I manually adjusted the focus during the first half as the humidity kept going up and down and I
was switching fan configurations.
 No problems tonight.
