An annular solar eclipse occurred at the Moon’s ascending node of orbit on Sunday, June 21, 2020,[1] with a magnitude of 0.994. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring 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. Occurring about 6.2 days after apogee (on June 15, 2020, at 1:55 UTC), the Moon's apparent diameter was smaller.[2]
The path of this annular eclipse passed through parts of the Democratic Republic of the Congo, South Sudan, Ethiopia, and Eritrea in Africa; the southern Arabian Peninsula, including Yemen, Oman, and southern Saudi Arabia; parts of South Asia and the Himalayas, including southern Pakistan and northern India; and parts of East Asia, including South China and Taiwan. A partial eclipse was visible throughout much of the rest of Africa, Southeast 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.
Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.[3]

See also: Eclipse cycle. This eclipse is part of an eclipse 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 a fortnight. The first and last eclipse in this sequence is separated by one synodic month.
