              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
A very loooooong winter's night. Which started out clear for most of A half, but clouds starting forming. There was precip in the counties around us but it never managed to cross the county line. There was a really bright red fireball a little after midnight! It was captured on the cloud cam and Amanda sent out an email.
No problems tonight.
