              ------------- ACTIVITY LOG --------------
Observing Specialist: T.McQuaid

Ran hub startNubs gcam and hub startNubs gcamera at checkout due to gcam exposures failing

Manually reset mirror covers at 18:30 after tui failed to open them, worked fine after

Stayed closed due to rainclouds in the vicinity at the start of the night, and periodic rain which became a consistent shower after 00:00. Rain and clouds started clearing out right before twilight but by then we had run out of usable time for science.
