There will be a polar annular solar eclipse tomorrow (Thursday 2021-06-10 08:00-13:30 UTC). The maximum eclipse is going to be experienced in Tromsø around 11:15 UTC, with about 50 % of the solar disc eclipsed by the Moon.

I am also recording another path, which is the Sodankylä-Skibotn path. This won't be as much affected by the eclipse.
