What is the eclipse season in China?

Solar eclipse, especially total solar eclipse, is a very rare astronomical phenomenon. Although there are thousands of records about solar eclipse in Chinese history books, due to the backwardness of modern comprehensive national strength, until the founding of New China, the scientific research and observation of solar eclipse in China was basically blank. Since the founding of the People's Republic of China, the total solar eclipse has been very rare in China. The first time was in the western part of Xinjiang on September 22, 1968. Under quite difficult circumstances, the relevant astronomical research institutions in China overcame many difficulties, made important scientific observations of solar eclipses, and gained valuable information and experience. About 11 years later, on February 16, 198, a total solar eclipse occurred in Yunnan province of China. However, the weather conditions in this area were not ideal that day, so many people missed the opportunity to enjoy the total solar eclipse. The largest organized total solar eclipse observation in China was on March 9, 1997, when the total solar eclipse belt brushed the Mohe River in the northernmost part of China.

However, the situation that the total solar eclipse does not favor China has been changed in recent two years. On August 1, 28 and July 22, 29, there were consecutive total solar eclipses, the first time in northwest China, and the second time in the densely populated Yangtze River basin. For friends who are interested in enjoying the total solar eclipse, this is definitely a good opportunity to feast their eyes. If you unfortunately miss these two total solar eclipses, the next total solar eclipse in China will be in 234.

The total solar eclipse on July 22, 29 attracted much attention, and the width and duration of its eclipse, which passed through a large population, was really rare. The only thing that is not ideal is the weather in the total eclipse zone. Friends who appreciate the total solar eclipse should always pay attention to the weather forecast to choose the observation site, and don't miss the opportunity.

This total solar eclipse basically occurred in the sparsely populated Eastern Hemisphere, starting from India, passing through Nepal, Bangladesh, Bhutan and Myanmar, and then entering China. The total eclipse belt passes through the southeast of Xizang Autonomous Region, the northwest of Yunnan Province, Sichuan Province, Chongqing, Hubei Province, northern Hunan Province, Anhui Province, northern Jiangxi Province, southern Jiangsu Province and northern Zhejiang Province, and enters the sea in Shanghai, the largest city in China. After that, the total eclipse belt will pass through the southern part of Kyushu, Japan and some islands in the Pacific Ocean, and finally end in the southeast Pacific Ocean. In more than five hours, the eclipse belt swept across the eastern hemisphere, with the longest total eclipse time in the Pacific Ocean, which can reach 6 minutes and 39 seconds. Most areas in the total eclipse belt in China can see the total eclipse for more than 4 minutes. Compared with the total solar eclipse in 28, there is no need to worry about the reception and observation ability of the total solar eclipse area in 29. According to rough statistics, there are 3 million people in the area where the total eclipse belt passes, and there are also many people in India. However, the solar horizon is low and the observation conditions there are not as good as in China. Chengdu, Chongqing, Wuhan, Hangzhou, Shanghai and other big cities are all in the whole food belt, and hotels of all grades are rich in tourism resources, which is an ideal choice for traveling with observation belts. The time of total eclipse in all parts of China varies from 9 am to 9: 37 am. The solar eclipse occurs in summer, which is a good opportunity for students to observe. It doesn't matter if you really don't have the conditions to observe in the total eclipse zone. A partial solar eclipse can be seen all over China.

March 2, 234. A total solar eclipse will occur in Xinjiang and parts of Tibet in western China, which also marks the beginning of the next solar eclipse season in China. On September 2, 235, the total solar eclipse belt will cross the northern part of China, and observers in Beijing will also have the opportunity to enjoy the total solar eclipse.

Because the orbits of the sun and the moon are both elliptical, their apparent diameters are different every time a solar eclipse occurs. And because the moon moves faster near perigee than near apogee, these changes work together, which makes the longest eclipse time of each eclipse different. For the same total solar eclipse, the total solar eclipse time is different for observers in different locations in the total solar eclipse zone. But what is certain is that the longest time to see food must be on the center line of the total eclipse zone, and the farther away from it, the shorter the time to see food.

The maximum apparent diameter difference between the sun and the moon is 2 ′ 38 ″, and the longest time for an equatorial observer is 7 minutes and 4 seconds. The maximum eclipse time of the total solar eclipse in West Africa in 1973 was close to this theoretical value. Under normal circumstances, the total solar eclipse lasts only 2-3 minutes, or even shorter, but an eclipse can last for 4 hours from the initial loss to the total loss in last contact.
