A total solar eclipse occurred at the Moon's descending node of orbit on Wednesday, July 22, 2009,[1][2][3][4] with a magnitude of 1.07991. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring only about 5.5 hours after perigee (on July 21, 2009, at 21:10 UTC), the Moon's apparent diameter was larger.[5]
This was the longest total solar eclipse during the 21st century, with totality lasting a maximum of 6 minutes and 38.86 seconds off the coast of Southeast Asia,[6] causing tourist interest in eastern China, Pakistan, Japan, India, Nepal and Bangladesh.

The total eclipse was visible from a narrow corridor through northern India, eastern Nepal, northern Bangladesh, Bhutan, the northern tip of Myanmar, central China and the Pacific Ocean, including the northern part of the Ryukyu Islands, the whole Volcano Islands except South Iwo Jima, Marshall Islands, and Kiribati.
Totality was visible in many large cities, including Dhaka and Dinajpur, and Chapai Nawabganj district in Bangladesh; Surat, Vadodara, Bhopal, Varanasi, Patna, Gaya, Siliguri, Tawang and Guwahati in India; and Chengdu, Nanchong, Chongqing, Yichang, Jingzhou, Wuhan, Huanggang, Hefei, Hangzhou, Wuxi, Huzhou, Suzhou, Jiaxing, Ningbo, Shanghai as well as over the Three Gorges Dam in China. However, in Shanghai, the largest city in the eclipse's path, the view was obscured by heavy clouds.[7][8] According to NASA, the Japanese island Kitaio Jima was predicted to have the best viewing conditions[9][10] featuring both longer viewing time (being the closest point of land to the point of greatest eclipse) and lower cloud cover statistics than all of continental Asia.
A partial eclipse was seen within the broad path of the Moon's penumbra, including most of Southeast Asia (all of Pakistan, India and China), East Asia, northern Oceania, and Hawaii.
The eclipse, and the reaction of thousands of observers at Varanasi was captured by the Science Channel Wonders of the Universe series hosted by Brian Cox.[11]
This eclipse may be the most-viewed total solar eclipse in history, with 30 million people in Shanghai and Hangzhou alone.[12]
Observations
![](http://upload.wikimedia.org/wikipedia/commons/thumb/0/0d/22Jul09_eclipse_Varanasi.jpg/300px-22Jul09_eclipse_Varanasi.jpg)
Thousands of pilgrims gathered on the banks of the Ganges River in Varanasi, India to experience the eclipse as a religious or spiritual event. Some people expected that there would be a relationship, either positive or negative, between their health and the occurrence of the eclipse.[13]
Indian scientists observed the solar eclipse from an Indian Air Force plane.[14]
The Chinese government used the opportunity to provide scientific education and to dispel any superstition. A flight by China Eastern Airlines from Wuhan to Shanghai took a slight detour and followed the course of the eclipse to allow longer observation time for the scientists on board.
Observers in Japan were excited by the prospect of experiencing the first eclipse in 46 years, but found the experience dampened by cloudy skies obscuring the view.
In Bangladesh, where the eclipse lasted approximately 3 minutes and 44 seconds, thousands of people were able to witness the eclipse despite rain and overcast skies.
Duration
![](http://upload.wikimedia.org/wikipedia/commons/thumb/c/c0/Moonsize.jpg/220px-Moonsize.jpg)
This solar eclipse was the longest total solar eclipse to occur in the 21st century, and will not be surpassed in duration until 13 June 2132 (Saros 139, ascending node) which will last for 6 minutes and 55 seconds. Totality lasted for up to 6 minutes and 38.86 seconds (0.14 seconds shorter than 6 minutes and 39 seconds), with the maximum eclipse occurring in the ocean at 02:35:21 UTC about 100 km south of the Bonin Islands, southeast of Japan. The uninhabited North Iwo Jima island was the landmass with totality time closest to maximum, while the closest inhabited point was Akusekijima, where the eclipse lasted 6 minutes and 26 seconds.[15]
The cruise ship Costa Classica was chartered specifically to view this eclipse and by viewing the eclipse at the point of maximum duration and cruising along the centerline during the event, duration was extended to 6 minutes, 42 seconds.
The eclipse was part of Saros series 136, descending node, as was the solar eclipse of July 11, 1991, which was slightly longer, lasting up to 6 minutes 53.08 seconds (previous eclipses of the same saros series on June 30, 1973, and June 20, 1955, were longer, lasting 7 min 03.55 and 7 min 07.74, respectively). The next event from this series will be on August 2, 2027 (6 minutes and 22.64 seconds).[16] The exceptional duration was a result of the Moon being near perigee, with the apparent diameter of the Moon 7.991% larger than the Sun (magnitude 1.07991) and the Earth being near aphelion[17] where the Sun appeared slightly smaller.
In contrast the annular solar eclipse of January 26, 2009 (Saros 131, ascending node) occurred 3.3 days after lunar apogee and 7.175% smaller apparent diameter to the sun. And the next solar eclipse of January 15, 2010 (Saros 141, ascending node) was also annular, 1.8 days before lunar apogee, with the Moon 8.097% smaller than the Sun.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight. The first and last eclipse in this sequence is separated by one synodic month.[6][21][22]

Saros 136
This eclipse is a part of Saros series 136, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on June 14, 1360. It contains annular eclipses from September 8, 1504 through November 12, 1594; hybrid eclipses from November 22, 1612 through January 17, 1703; and total eclipses from January 27, 1721 through May 13, 2496. The series ends at member 71 as a partial eclipse on July 30, 2622. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of annularity was produced by member 9 at 32 seconds on September 8, 1504, and the longest duration of totality was produced by member 34 at 7 minutes, 7.74 seconds on June 20, 1955. All eclipses in this series occur at the Moon’s descending node of orbit.[24]

Tritos series
This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

Inex series
This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

In Sichuan province, China, 150 km southwest of Chengdu many people ascended Mount Emei to view the eclipse. While viewing conditions were not ideal due to thick cloud cover, typical of this region and altitude, the effects were reported as impressive. The summit of Mt. Emei contains numerous Buddhist temples and statues, as well as a large candle and incense lighting ceremony/area. During the eclipse day turned to night, leaving only the candles to cast a unique lighting on the adjacent Buddhist statues and buildings.
