What is a solar eclipse?
A solar eclipse occurs on a new moon day when the Moon comes in between the Earth and the Sun and when all the three objects are aligned. An annular solar eclipse will occur when the angular diameter of the Moon falls short of that of the Sun so that it cannot cover up the latter completely. As a result a ring of the Sun's disk remains visible around the Moon.
According to the space.com, the 'ring of fire' will shine with only one-tenth of the sun's normal total light and "near the point of greatest eclipse over the polar region, the annular phase will last up to three minutes and 51 seconds..."
