              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend,C.Gray
We had a few minor errors with ARCTIC exposures at the start of the night probably related to the hub restart today but nothing that wasn't resolved quickly.
Fantastic weather with good seeing all night.
