              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Good seeing with some clouds in the second half of the night. Pollen counts were low all night.
West winds all night so we weren't really in danger of smoke from the nearby fire.
No telescope or instrument problems.
