              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started nice and clear, though the winds were occasionally gusting over 30 mph. Seeing stayed surprisingly good through all the wind! However, a random spike of humidity hit near midnight that kept us closed for 1.4 hrs. Then it blew out as fast as it blew in and we were able to continue until dawn.
