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.

The telescope is parked. The de-icing is on. At roughly midnight (CET) the wind calms down and it is not snowing anymore. It seems that the fog might also disappear soon. At 00:22 CET the sky is clear and the telescope moves out of the parking position. We now need to wait a bit until the primary surface relaxes after the de-icing. |
