An annular solar eclipse occurred on Sunday, June 21, 2020. An annular solar eclipse is a solar eclipse whose presentation looks like a ring, or annulus; it occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most, but not all, of the Sun's light. In this instance, the Moon's apparent diameter was 0.6% smaller than the Sun's. [1]
The path of this annular eclipse passed through parts of Central and Eastern Africa; southern Arabian Peninsula, including Yemen, Oman, and southern Saudi Arabia; parts of South Asia and the Himalayas, including southern Pakistan, northern India, and Nepal; parts of East Asia, including South China and Taiwan, and part of Micronesia, including Guam. [2] A partial eclipse was visible throughout much of the rest of Africa, southeastern Europe, most of Asia, and in New Guinea and northern Australia just before sunset. In Europe, the partial eclipse was visible to places southeast of the line passing through parts of Italy, Hungary, Ukraine, and southwestern Russia. [2]
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. [3]
Note: Partial solar eclipses on February 15, 2018, and August 11, 2018, occurred during the previous semester series.

It is a part of Saros cycle 137, an eclipse series repeating every 18 years and 11 days, containing 70 events. The series started with the partial solar eclipse on May 25, 1389. It contains total eclipses from August 20, 1533, through December 6, 1695, the first set of hybrid eclipses from December 17, 1713, through February 11, 1804, the first set of annular eclipses from February 21, 1822, through March 25, 1876, a second set of hybrid eclipses from April 6, 1894, through April 28, 1930, and the second set of annular eclipses from May 9, 1948, through April 13, 2507. The series ends at member 70 as a partial eclipse on June 28, 2633. All eclipses in this series occurs at the Moon’s ascending node.

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 18th century:

A total solar eclipse occurred at the Moon’s descending node of the orbit on Thursday, July 11, 1991. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Totality began over the Pacific Ocean and Hawaii moving across Mexico, down through Central America and across South America ending over Brazil. It lasted for 6 minutes and 53.08 seconds at the point of maximum eclipse. There will not be a longer total eclipse until June 13, 2132. This was the largest total solar eclipse of Solar Saros series 136, because eclipse magnitude was 1.07997.
The solar eclipse of May 20, 2012 was an annular solar eclipse that was visible in a band spanning through Eastern Asia, the Pacific Ocean, and North America. As a partial solar eclipse, it was visible from northern Greenland to Hawaii, and from eastern Indonesia at sunrise to northwestern Mexico at sunset. The moon's apparent diameter was smaller because the eclipse was occurring only 32 1/2 hours after apogee.
A total solar eclipse occurred at the ascending node of the Moon's orbit on Tuesday, July 2, 2019, with an eclipse magnitude of 1.0459. Totality was visible from the southern Pacific Ocean east of New Zealand to the Coquimbo Region in Chile and Central Argentina at sunset, with the maximum of 4 minutes 33 seconds visible from the Pacific Ocean. The Moon was only 2.4 days before perigee, making it fairly large.

Annularity was visible in Cape Verde, Annobón Island of Equatorial Guinea, Gabon, the People's Republic of Congo, Zaire, northern Uganda, southern Sudan, northwestern Kenya, Ethiopia and Somalia. The Sun's altitude was 66°. Occurring 6.5 days before apogee, the Moon's apparent diameter was near the average diameter.
An annular solar eclipse occurred at the moon's descending node of its orbit on Tuesday, May 10, 1994. It was visible over a wide swath of North America, from Baja California across the Midwest of the United States up through Ontario and Nova Scotia in Canada. Occurring only 1.6 days after apogee, the moon's apparent diameter was smaller than the sun. This solar eclipse belonged to Saros series 128.
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, 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.

An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible in Mexico, the United States, Azores Islands, Morocco and Algeria. It was the first annular solar eclipse visible in the US in 33 years. The moon's apparent diameter was near the average diameter because occurs 6.7 days after apogee and 7.8 days before perigee.
