An annular solar eclipse occurred at the Moon’s ascending node of orbit on Thursday, June 10, 2021,[1][2][3][4] with a magnitude of 0.9435.

Occurring about 2.3 days after apogee (on June 8, 2021, at 3:30 UTC), the Moon's apparent diameter was smaller.

[5] The annular eclipse was visible from parts of northeastern Canada (particularly Ontario and Nunavut), Greenland, the Arctic Ocean (passing over the North Pole),[6] and the Russian Far East.

[7] The annular eclipse started at 09:55 UTC for 3 minutes 37 seconds along the northern shore of Lake Superior in Ontario, Canada.

After this, it then travelled across Baffin Bay and along the northwestern coast of Greenland, where the point of greatest eclipse occurred at 10:41 UTC in Nares Strait for 3 minutes 51 seconds.

The shadow then crossed Ellesmere Island and the Arctic Ocean, passing over the North Pole (which was located away from the central line of the eclipse but saw 2 minutes and 36 seconds of annularity), before heading south towards northeastern Siberia, where the city of Srednekolymsk saw 3 minutes and 35 seconds of annularity at 11:27 UTC.

Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee).
