An annular solar eclipse occurred on Thursday, June 10, 2021, when the Moon passed between Earth and the Sun, thereby partly obscuring the image of the Sun for a viewer on Earth. During the eclipse, the Moon's apparent diameter was smaller than the Sun's, so it caused the Sun to look like an annulus. The annular eclipse was visible from parts of northeastern Canada, Greenland, the Arctic Ocean (passing over the North Pole),^[1] and the Russian Far East, whilst the eclipse appeared partial from a region thousands of kilometres wide, which included northeastern North America, most of Europe, and northern Asia.^[2]

Path[]

The annular eclipse started at 09:55 UTC for 3 minutes 37 seconds along the northern shore of Lake Superior in Ontario, Canada. The path of the antumbral shadow then headed across Hudson Bay through northwestern Quebec and the Hudson Strait to Baffin Island in Nunavut, where the town of Iqaluit saw 3 minutes and 5 seconds of annularity. 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 Naires 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. Shortly afterwards, the central line of the annular eclipse ended at 11:29 UTC.^[3]^[4]

Solar eclipses of 2018–2021[]

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.^[5]

Note: Partial solar eclipses on February 15, 2018, and August 11, 2018, occurred during the previous semester series.

Saros 147[]

Solar saros 147, repeating every about 18 years and 11 days, contains 80 events. The series started with a partial solar eclipse on October 12, 1624. It has annular eclipses from May 31, 2003, to July 31, 2706. There are no total eclipses in this series. The series ends at member 80 as a partial eclipse on February 24, 3049. The longest annular eclipse will be on November 21, 2291, at 9 minutes and 41 seconds.^[6]

Inex series[]

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

In the 19th century:

Solar saros 140: total solar eclipse of October 29, 1818
Solar saros 141: annular solar eclipse of October 9, 1847
Solar saros 142: total solar eclipse of September 17, 1876

Inex series members between 1901 and 2100:
August 30, 1905 (Saros 143)	August 10, 1934 (Saros 144)	July 20, 1963 (Saros 145)
June 30, 1992 (Saros 146)	June 10, 2021 (Saros 147)	May 20, 2050 (Saros 148)

Metonic series[]

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
