Solar eclipse of June 10, 2021

An annular solar eclipse will occur on Thursday, June 10, 2021. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. This eclipse will be unusual as the path of the annular eclipse will move to the north east (45°), then north (0°), north west (315°), west (270°), south west (225°), south (180°), and finally south east (135°) across the Arctic, while most eclipse paths move west to east. This reversal is only possible in polar regions. This eclipse is also notable for the fact that the path of annularity will pass over North Pole.

While the eclipse is visible primarily in northern Canada, in Greenland and in north-east of Russian Far East, in the northeastern United States and Canada, the sun will be partially eclipsed at sunrise, which will be between 5 and 6 A.M. (EDT)

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.[1]

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.[2]

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 1818 Oct 29

• Solar Saros 141: Annular Solar Eclipse of 1847 Oct 09

• Solar Saros 142: Total Solar Eclipse of 1876 Sep 17

In the 22nd century:

Solar Saros 150: Partial Solar Eclipse of 2108 Apr 11

Solar Saros 151: Annular Solar Eclipse of 2137 Mar 21

Solar Saros 152: Total Solar Eclipse of 2166 Mar 02

Solar Saros 153: Annular Solar Eclipse of 2195 Feb 10

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.
