Phase reference cycle too tight for antenna to follow reliably. No other known problems.

Effelsberg (Uwe at Wed Mar 10 08:25:44 2021) Minor failures: WIND

Bad weather and bad luck. Thick clouds and snow from time to time. Antenna had to stop from 10:50 UT to 11:40 UT because of snow fall. The Mark6 crashed at about 8:10 UT, reboot and restart of the schedule took until 8:40 UT. On top, the phase-ref cycle was a bit tight and the FS did not report "on-source" for all scans. Nevertheless the antenna was probably on source for 5-10s in each cycle. But likely not much more.
