"Annular eclipses are similar to total eclipses in that the
moon, Earth and sun are aligned so that the moon moves directly in
front of the Sun as viewed from Earth,"
"But a total eclipse does not happen, that is the moon does
not completely block out the visible disk of the sun because the moon is
farther away and so its apparent size in the sky is [slightly] smaller than the
sun. This means that a tiny ring of annulus of the solar disk is visible around
the moon."
Sunday's
solar eclipse is what is known as an annular eclipse, in which the moon does
not completely cover the sun as it passes between the star and Earth as seen
from our planet. Instead, a ring of sunlight will still shine around the outer
edge, hence its nickname: a "ring of fire" eclipse.

Where to see it
An annular solar eclipse is set to take place on June
21 and will start at 9:15 AM IST. The eclipse will hit its peak at 12:10
AM IST. A solar eclipse like this one occurs only when the Moon is farthest
from the Earth. However, it comes in between the Earth and the Sun blocking
most of the Sun. Hence, it creates something called “ring of fire” that looks
mesmerising.
It
will be visible over central Africa, the southern Arabian Peninsula, Pakistan,
Northern India and South Central China, Young said. A partial eclipse will be
seen over most of Asia, Africa, South and East Europe, northern Australia and
parts of the Pacific and Indian Oceans, he added.
The
entire eclipse will last about 3.75 hours, but the duration as it passes over
individual locations will equal to around a minute and a half.
During the peak, that will actually shorten to just over 30 seconds..
