We had a small power glitch but no data was lost and everything was back to normal in less than 5 minutes

Comments: 

Another very good night. COSMOS behaved well and we were able to observe 23 stars. The seeing degraded (humidity started to increase as well) at about 3:30 am local time. DIMM2 stopped updating by 3:30 am as well.
