              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
An amazingly clear evening during monsoon season! The seeing wasn't too bad, either. Not stellar (haha) but not too bad! There seemed to be a light left on in the NA1 crawl space, perhaps for laser work? Either way, we turned that off during checkouts.
No problems tonight
