              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
nicfps needed an init at the beginning of the night.
No rain tonight but plenty of fog, clouds, humidity, more fog and humidity. At one point the humidity dropped and I thought we would be able to open but the clouds were *right* above us and, by the time they cleared again, more humidity.
