              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
At 00:07 I went to slew to rotate the tertiary and Motor Control Buffer Empty was reported for alt and az.  I had to do an axis init and then I was able to slew.  There was no issues with the observer, just when I went to slew. Position was at 188, 73.  It was rather windy so perhaps that had something to do with it?
Things were clear at the start of the night but became increasingly cloudy as thing night continued.  The clouds were high and non-threatening.  The wind almost made us close but we were able to pull through. The seeing was poor to meh all night.
