              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Clouds, high humidity, and nearby radar after 02:00 kept us closed. Gave up a little after 04:00 as CU01 wouldn't be able to observe the transit after this point and no real hope of the weather improving.
Low alt drive hum during test slews at 10 alt again.
