An annular solar eclipse occurred at the Moon's ascending node of orbit on Friday, January 15, 2010,[1][2] with a magnitude of 0.919. 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. It was the longest annular solar eclipse of the millennium,[3] and the longest until December 23, 3043, with the length of maximum eclipse of 11 minutes, 7.8 seconds, and the longest duration of 11 minutes, 10.7 seconds.[4] This is about 4 minutes longer than total solar eclipses could ever get. (The solar eclipse of January 4, 1992, was longer, at 11 minutes, 40.9 seconds, occurring in the middle of the Pacific Ocean.)[5]
Lasting 11 minutes and 7.8 seconds, and eclipse magnitude of only 0.91903, this was the longest and smallest annular solar eclipse of the 21st century. The eclipse was visible as only a partial eclipse in much of Africa, Eastern Europe, the Middle East and Asia. It was seen as an annular eclipse within a narrow stretch of 300 km (190 mi) width across Central Africa, Maldives, South Kerala (India), South Tamil Nadu (India), Sri Lanka and parts of Bangladesh, Burma and China.
