              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Thanks Jack for the remote support!
Didn't open at sunset due to incoming weather concerns. Opened just after 9pm since the clouds cleared, but before meaningful data could be taken, the humidity spiked again.
Opened at 2:50am but had to close again due to another rapid humidity spike before good data could be taken.
We gave up for the night at 4:15am.
Morning fills are done.
