              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend,C.Gray
During checkout mirror covers had to be opened manually.
APO1 was supposed to start the night, but time was ceded to JH04.
Windy at the start of the night--but clear!
At 22:05 we closed the dome due to very high pollen. We believe the ~15-40 mph winds tonight knocked a lot of pollen loose from the trees. New guidance from Bill suggests that in the future we can stay open with high pollen IF the humidity stays under 50%, but we were over 60% humidity as well as experiencing too-high speed winds.
As of 23:53, wind gust speed was over 35 mph and rising.
At the start of B-half, humidity was dropping but the wind speed was still too high.
By about 02:20, the humidity (~45%) and wind ( 1u per 0.1 cubic feet.
