What is a Hybrid Solar Eclipse?

A hybrid Solar Eclipse occurs when there is a combination of an annular eclipse and a total solar eclipse.
It is caused when the moon's shadow moves across Earth - making a transition to another.
During this rare eclipse, the Sun forms a ring-like shape - known as the ‘ring of fire’ - for a few seconds.

Ningaloo Eclipse: where will it be visible?

The eclipse will be visible from Australia, East and South Asia, the Pacific Ocean, Antarctica, and the Indian Ocean, however, not in India.
During the ‘annual ring of fire’ - it will be visible for a few seconds in the Indian and Pacific oceans.
