Summary of season 2020 -2021

During the past season, the best periods to see the northern lights were early fall and this spring due to the clear weather.
From late autumn all the way to the beginning of this spring, it was more or less cloudy which hindered the view of the northern lights.
The northern lights were mainly short-lived and their intensity was mainly level 3 (scale; dim 1 … 5 bright).
We are waiting with interest next autumn, then we will probably see magnificent northern lights.
