Problems: 

I had three occlusion alarms at 03:12, 03:19 and 03:26. We were looking at the top ring webcam at the time of the last of those alarms and the problem was that the exposure started and the dome was still moving. It happened again at 7:40, 7:47 and 8:33 UT. It had been a while since I had seeing these oclusion alarms.

 

A few bad exposures due to elongation by the high wind.
