              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had clouds at the start of the night that only became worse. Wind was to the north and east so seeing wasn't the best. Radar started appearing to the east and we closed at 23:32 before it got too close. We had sprinkles off and on after midnight until dawn.
No problems tonight.
