Annular Solar Eclipse

A few lucky people in the Indian Ocean will be treated to a rare event on Monday when an annular solar eclipse will transform the Sun into a dark disc with a blazing ring-shaped corona around its rim.

In this phenomena, the Moon moves between the Sun and Earth, casting its shadow on the terrestrial surface.

In an annular eclipse, a tiny shift in distance that results from celestial mechanics means the Moon does not completely cover the Sun's face, as it does in a total eclipse.

Instead, for those directly under the alignment, the Moon covers most of the Sun's surface, and a ring-like crown of solar light blazes from the edge of the disk.

According to NASA, the total eclipse track will run from west to east on Monday from 0606 GMT to 0952 GMT.

It will traverse the Indian Ocean and western Indonesia before petering out just short of Mindanao, the Philippines.

Some are in southern third of Africa, Madagascar, Australia, Southeast India, Southeast Asia and Indonesia will seen a partial eclipse

On this monday(Jan 26),it will be the only annular solar eclipse this year. The last was on 7 February.

If you miss this annular solar eclipse,you will see this phenomena again on 15 January 2010.

The big event for eclipse junkies this year is on July 22, when a total solar eclipse will be visible from India and China, the world's two most populous countries.
