              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
- dataq needed a restart
- dome cameras needed a refresh
We had strong winds all night and high dust for half the night. We were able to open at midnight so long as we kept away from the west. however, we had a collision at 77 alt when user pointed dead into the wind. I was attempting to correct the course before the wind gusted but was not able to correct in time. We had a motion error when moving from alt 70 to 50 mostly out of the wind so I wonder if that was a "normal" motion error.
Despite the high dust and winds, we had moderately good seeing. Sure, the numbers look bad, but we were at high airmass.
