              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Humidity was a little high and we had a few clouds, but tonight the weather was mostly okay! We did close for about an hour due to radar blips early in the night.
At the start of the night the tui log was being spammed with telmech status shutter commands, but Shane fixed that for us (thank you).
