The solar eclipse of July 22, 2009 was the longest total solar eclipse of the 21st century, lasting as much as 6 minutes and 39 seconds in some places. It caused tourist interest in eastern China, India and Nepal.
The eclipse was part of Saros series 136, as was the record-setting solar eclipse of July 11, 1991. The next event from this series will be on August 2, 2027. The exceptional duration was a result of the Moon being near perigee, with the apparent diameter of the Moon 8% larger than the Sun (magnitude 1.080) and the Earth being near aphelion where the Sun appeared slightly smaller.
This was the second in the series of three eclipses in a one-month period, with the lunar eclipse on July 7 and the lunar eclipse on August 6.
