Wednesday, July 22, 2009 will be a memorable day for those who live in Asia – as they’ll witness the longest solar eclipse in the 21st century, lasting for six minutes and 39 seconds. The eclipse will reach this six-minute maximum duration point over the Pacific Ocean.

The eclipse will be visible in and around central India and in parts of Nepal, Bangladesh, Bhutan, Myanmar and China. This will be the most watched eclipse – as it will be right over the most densly populated area in the world. But hey, if you’re not in the area of the eclipse then you can always watch it online here.
