              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The sky was clear with good to moderate seeing all night, obviously because the class left.
Near 4am, kosmos didn't read out an exposure. I fixed the problem by restarting the kosmos icc but I submitted a PR just in case (PR 2013).
