              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend, C.Gray
Dataq was frozen again, I had to power cycle it to restart it.
Jack was getting a bunch of error emails from the optical sky camera even though the camera seemed to be functional, he ended up restarting the computer and it solved the problem.
We didn't open during A-half due to overcast skies and on-and-off nearby radar from the hurricane. We got on sky a little after handover when it finally cleared up a bit. We had good seeing and the clouds weren't too bad for the class for the rest of the night!
