About the total solar eclipse ~

The reason why the total solar eclipse in 2009 was so long (the longest was more than 6 minutes) was that the moon had just arrived at perigee a few hours before the total solar eclipse began. At this close distance, the moon looks 8% bigger than the sun, so the moon will cast a bigger shadow on the earth and the total solar eclipse will last longer.

The umbra of the moon (the central part of the shadow) first touched the Earth at the sunrise in Khambhat, western India, at 00:53 GMT, 8:53 Beijing time and 6:23 local time (the time zone in this area is 5.5 East). In a few seconds, the coastal city of surat will be shrouded in the shadow of the moon for three minutes, when the sun has just risen, only 3 degrees above the eastern horizon.

As the umbra moves eastward, the height of the sun in the area where the total solar eclipse occurs will rise rapidly. The shadow of the moon crossed India in eight minutes and entered northern Bangladesh and eastern Nepal. In a few minutes, the umbra of the moon will pass through most parts of Bhutan. At this time, the total solar eclipse time on the center line of the total solar eclipse began to exceed 4 minutes. At 7 o'clock local time, the height of the sun is 2 1 degree, and the width of the total solar eclipse zone is 225 kilometers (140 miles).

The shadow of the moon continues to push eastward, passing through northern Myanmar, a corner of Tibet in China and northern Yunnan. After passing through Sichuan Province, after 9: 0012 Beijing time, the moon shadow turned Chengdu from day to night, and Chengdu citizens could watch the total solar eclipse for more than 3 minutes. At this time, the total solar eclipse time in the middle line of the total solar eclipse in the south is close to 5 minutes. Chongqing, another big city south of the center line of the total solar eclipse, will experience a total solar eclipse for more than 4 minutes at 9: 15 Beijing time.

The shadow of the moon with a diameter of nearly 250 kilometers continues to move eastward at a speed of more than 2,000 kilometers per hour in the Yangtze River Basin of China. ..

At 9: 25 Beijing time, the shadow of the moon swept through Wuhan, making the fourth largest city in China with a population of over 10 million quickly enter the night for 5 and a half minutes. Wuhan is located slightly to the south of the center line of the total solar eclipse, and10 million people can enjoy the total solar eclipse for 5.5 minutes. At this time, the height of the sun is 48 degrees, and the bandwidth of the total lunar eclipse is 244 kilometers.

At 9: 33, there will be a total solar eclipse in the most beautiful Huangshan scenic spot in China. If you watch the sunrise in Huangshan scenic spot on the same day and enjoy the total solar eclipse for five minutes at 9: 33, you can watch the sunrise, total solar eclipse and sunset in Huangshan in one day. This is really glad you came.

After 9: 35, the shadow of the moon approaches the Pacific coast, that is, the Yangtze River Delta in China, a densely populated place in China, and a tourist attraction in China: Jiangnan Water Town. Hangzhou, Suzhou, Wuxi, Ningbo, Shanghai and other economically developed cities in the Yangtze River Delta ushered in a total solar eclipse of 3 to 5 minutes in a few minutes. Hangzhou is located about 50 kilometers south of the center line of the total solar eclipse, and you can see the total solar eclipse lasting more than 5 minutes. At this time, the total solar eclipse time on the central line of the total solar eclipse is 5 minutes 5 1 s, and the total solar eclipse time will continue to increase eastward. Wuxi and Suzhou along the center line of the total solar eclipse were also blocked by the moon shadow for 4-5 minutes, while Shaoxing and Ningbo, south of the center line of the total solar eclipse, turned from day to night almost at the same time. Jiaxing, the best observation city in the middle line of the total solar eclipse in East China, will usher in the largest gathering of total solar eclipse lovers in history. The total solar eclipse lasts for 5 minutes and 50 seconds. As early as last year, quite a few foreign group enthusiasts booked hotels around the total solar eclipse. Up to now, it is difficult to book hotels in Jiaxing.

In less than a minute, China's largest city, Shanghai with a population of more than 20 million, will enter the total lunar eclipse, and China's financial center, Greater Shanghai, will change from day to night for five minutes.

The shadow of the moon passes through the Yangtze River Delta, then enters the East China Sea of China, passes over the Japanese volcanic island, and then turns southeast across the Pacific Ocean.

This spectacular total solar eclipse lasted for 6 minutes and 39 seconds at 2: 35 GMT and 10: 35 Beijing time. The shadow of the moon continues to advance to the southeast of the Pacific Ocean. The only route that the second half of the total solar eclipse passes through is the ocean and some small islands, which is about 12 Beijing time and 4: 00 GMT. The shadow of the moon passes through the equator from north to south, and the whole total solar eclipse will end at 12: 18 Beijing time and 4: 18 GMT. The time for the shadow of the moon to project on the earth (total eclipse time) lasted for 3.4 hours, covering 0.7% of the earth's surface, and then left the earth and returned to space.
