              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS red HV again was found off during my afternoon checkout.  I restarted it.  A PR was submitted.
I opened before sunset to get things cooling, but during twilight the sky grew increasingly worse and we had a system both to our N and coming up from the SW, so I opted to close.
We had thunderstorms during the first half of the night and clouds and humidity during the second half.  We never re-opened and called it at 04:00
DIS Red HV was found off again at the end of the night.  I re-started it again.
