We successfully arrived at the telescope with the first winter transport of the season.
Afternoon shift (16:00-21:00; Ioannis + Stefano): we try to focus but the sky is highly variable. We give up and stop when the peak-to-peak variations in the timeline of pointings reach 400 Jy/beam (four hundred). We're now immersed in the clouds. Temperature -9 Celsius; humidity 100%, wind ~10 m/s.
