              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had some cirrus for most of A half, which wasn't a problem. What was a problem was the dust. It kept creeping up until we had to close near 11pm. The dust remained high and we were not able to open.
I left the secondary mirror controller off except to focus. I restarted it when I finished for the night.
