An annularsolar eclipse occurred at the Moon’sascending node of orbit on Sunday, June 21, 2020,[1][2][3][4][5][6][7] with amagnitude of 0.994. Asolar eclipse occurs when theMoon passes betweenEarth and theSun, thereby totally or partly obscuring the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon'sapparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like anannulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 6.2 days afterapogee (on June 15, 2020, at 1:55 UTC), the Moon's apparent diameter was smaller.[8]

Path

[edit]

The path of this annular eclipse passed through parts of theDemocratic Republic of the Congo,South Sudan,Ethiopia, andEritrea inAfrica; the southernArabian Peninsula, includingYemen,Oman, and southernSaudi Arabia; parts ofSouth Asia and theHimalayas, including southernPakistan and northernIndia; and parts ofEast Asia, includingSouth China andTaiwan.[9] A partial eclipse was visible throughout much of the rest ofAfrica,Southeast Europe, most ofAsia, and inNew Guinea and northernAustralia just before sunset. In Europe, the partial eclipse was visible to places southeast of the line passing through parts ofItaly,Hungary,Ukraine, and southwesternRussia.[9]

Eclipse season

[edit]
See also:Eclipse cycle

This eclipse is part of aneclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by afortnight. The first and last eclipse in this sequence is separated by onesynodic month.

[edit]

This eclipse is a member of asemester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternatingnodes of the Moon's orbit.[11]

The partial solar eclipses onFebruary 15, 2018 andAugust 11, 2018 occur in the previous lunar year eclipse set.

Saros 137

[edit]

This eclipse is a part ofSaros series 137, repeating every 18 years, 11 days, and containing 70 events. The series started with a 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; the second set of hybrid eclipses from April 6, 1894 throughApril 28, 1930; and the second set of annular eclipses fromMay 9, 1948 through April 13, 2507. The series ends at member 70 as a partial eclipse on June 28, 2633. Its eclipses are tabulated in three columns; every third eclipse in the same column is oneexeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of totality was produced by member 11 at 2 minutes, 55 seconds on September 10, 1569, and the longest duration of annularity will be produced by member 59 at 7 minutes, 5 seconds on February 28, 2435. All eclipses in this series occur at the Moon’sascending node of orbit.[12]

Metonic series

[edit]

Themetonic 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.

Tritos series

[edit]

This eclipse is a part of atritos cycle, repeating at alternating nodes every 135synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

This eclipse is a part of the long periodinex cycle, repeating at alternating nodes, every 358synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.
