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]

Path

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]

Saros 137

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.

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 18th century:

In the 23rd century:

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.

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.
