              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIFFIT visiting instrument tonight.
Russet did an instrument block and they got some on sky engineering performed as well.  We fought clouds for the first half.
Second half also fought clouds and by around 02:10 they were starting to win.  We closed at 02:40 as clouds and humidity were now over limit.
The clouds stayed and we never re-opened.
I restarted the Hub and TCC
I reset the ALt, Az, and NA2 drive controlllers
The rotator was zero'ed yesterday before DIFFIT was mounted today.
We never re-opened for the remainder of the night.
