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.
Previous annular solar eclipse will occurred on 2nd July 2019 and this year it happening on June 21, 2020.
The full annular eclipse will be visible from parts of Africa and Asia. “A narrow stripe from Africa to the Pacific Ocean will see the Moon in front of the Sun (blocking 99.4% of the Sun at its peak in northern India) such that only a bright ring is visible,” NASA said in a skywatching update for June.
The National Astronomical Observatory of Japan will offer a Japanese-language livestream with its view of a partial eclipse starting at 11:45 p.m. PT on Saturday.
