Also Present: 
Sean Points
Problems: 

At some point, an acq image had triple stars (e.g. /data2/observer/20210106/n1.55871). Claudio noticed the problem also on the guide. He moved the telescope to the zenith, restarted the appropriate software, and things went back to normal. This process took about 20 minutes. Right after that, we had a power outage for ~5 min.

Comments: 

Besides the above, the night went pretty well. Seeing was consistent in the 1-1.3 range and we managed to observe 28 stars!

PS: The DIMM2 website is not refreshing, so I estimated the seeing from the acquisition images using the 0.29 pixel scale
