              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Agile did not successfully check out. It aborted after 2/5 images, but the script had the output "done." Not sure if this is expected or not.
Dust spiked 5 minutes after I opened, and kept us closed the remainder of the night, along with the humidity. We gave up just before 5am.
Thank you Cary for coming in to fix the omea computer when it wouldn't restart properly.
