              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I needed to reset the mirror covers during afternoon checkout.
Seeing was poor at the start of the night, then improved to just under sub arc-second, then deteriorated during the 2nd half of the night.
The winds also picked up during the 2nd half of the night.
