Solar eclipse of June 21, 2020
21st-century annular solar eclipse
An annular solar eclipse occurred on Sunday, June 21, 2020.[1][2][3][4][5] 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.[6]

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.[7] 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.[7]

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.[8]
Note: Partial solar eclipses on February 15, 2018, and August 11, 2018, occurred during the previous semester series.

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:
- Solar Saros 127: Total Solar Eclipse of 1731 Jan 08
- Solar Saros 128: Annular Solar Eclipse of 1759 Dec 19
- Solar Saros 129: Annular Solar Eclipse of 1788 Nov 27

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.
