              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started with storms. We did not open at sunset. Storms kept raging close by all around us, but it was frustrating clear overhead.
Storms gave out around 00:00. It was became safe to open and we did so at 00:32. We stayed open thereafter. Problem with NA2. PR sent.
