              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had a calm clear night with good seeing and only a few thin clouds, and got to observe all night!
Focused KOSMOS in image mode on the main detector.
Timestamp 07:47:19 weird power fluctuation; lights flickered and the telescope stopped tracking, but we got back on sky immediately. I had to reset the mirror covers in the morning to close them.
Happy Autumnal Equinox!
