Longest Total Solar Eclipse of the Century

The Total Solar Eclipse on 22nd July will be visible from parts of India, Nepal, Bhutan, Myanmar and China. What is special about this eclipse is its duration. The maximum duration of totality reaches 6 minute 38.7 second, somewhere in the Pacific Ocean southeast of Japan. It will be surpassed in duration only by the solar eclipse of 13 June, 2132!


In India the eclipse will be seen in the early morning and the duration of totality will range from 3m 14s at Surat in Gujrat to about 3m 47s at Siliguri in West Bengal.

It will be the first total solar eclipse visible from India in this century. And it will have to wait 25 years for the next total solar eclipse.

From Kolkata, a partial solar eclipse of magnitude 0.911 will be seen. That means 91.1 % of the Sun will be covered by the Moon. Here it begins at 5:28 a.m., reaches maximum eclipse at 6:26 a.m., and ends at 7:30 a.m.

For other cities in India take look at this article [pdf].

Science Reporter Cover (July 2009)This month's issue of Science Reporter covers this solar eclipse with detailed information and discussions about several related topics, like geometry of eclipses, types of eclipses, shadow bands, the saros cycles, famous historical eclipses etc. It also carries an article on how to photograph a solar eclipse. There are also other excellent astronomy articles as well. They devoted this issue to astronomy to mark the International Year of Astronomy 2009.

Update: Clouds spoiled most of the Eclipse. I could only take this picture with my mobile camera.


Well, the clouds did something good. The thinner clouds acted as a natural solar filter!
