              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
KOSMOS disperser wheel timed out during evening checkout when I moved it to blue (3) but I wasn't paying attention to which empty slot it was at prior to that (2023-10-01 00:11:39).
Wind picked up with thunderstorms and hail after 20:30, and we had wind gusts up to about 50mph. We had more rain, high humidity, high winds, and a lot of radar nearby for the rest of the night, along with a lot of clouds. We didn't open at all tonight.
