              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Dataq didn't need a restart! :D
But there was fog, fog, fog. And then!! There was a shift! And we were able to open a little after 2 am when the humidity dropped to 70% and we opened! Seeing was moderate, which was surprising given the fog! We did lots of training for NA01 and they should be ready to go tomorrow!
No problems tonight.
