An annular solar eclipse occurred on June 21, 2020. 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 solar eclipse occurred one lunar year after the July 2, 2019 eclipse.

Visibility

The central path of this annular eclipse passed through parts of Central and Eastern Africa, including Congo Republic, DR Congo, the Central African Republic, South Sudan, Ethiopia, Eritrea, and Djibouti; the southern Arabian Peninsula, including Yemen, Oman, and southern Saudi Arabia; parts of South Asia and the Himalayas, including southern Pakistan, northern India, Nepal, and Tibet; parts of East Asia, including South China and Taiwan, and part of Micronesia, including Guam.^[1] A partial eclipse was visible throughout much of the rest of Africa, southeastern Europe, most of Asia (except the north part of Siberia and most of the island of Java), and in New Guinea and the north of Australia just before sunset. In Europe, the partial eclipse was visible for places southeast of the line roughly passing through Perugia, Miskolc, Lviv, and Yaroslavl.^[1]

For Oman and India, it was the second annular eclipse 6 months after the December 2019 eclipse.^[2]

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.^[3]

The partial solar eclipses on February 15, 2018 and August 11, 2018 occur in the previous lunar year eclipse set.

Saros 137

It is a part of Saros cycle 137, repeating every 18 years, 11 days, containing 70 events. The series started with partial solar eclipse on May 25, 1389. It contains total eclipses from August 20, 1533 through December 6, 1695, first set of hybrid eclipses from December 17, 1713 through February 11, 1804, first set of annular eclipses from February 21, 1822 through March 25, 1876, second set of hybrid eclipses from April 6, 1894 through April 28, 1930, and 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. The longest duration of totality was 2 minutes, 55 seconds on September 10, 1569. Solar Saros 137 has 55 umbral eclipses from August 20, 1533 through April 13, 2507 (973.62 years).

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.

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.
