              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with a few clouds that were on and off for the night. See was pretty epic! OU01 gave up some of their time to NA02, which I was thankful for since it took me some time for focus Kosmos.
No problems tonight.
