How many times did the total solar eclipse appear in China? How many years does it appear on average?

Throughout the 20th century, there were seven total solar eclipses in China.

190765438+1October 14 The total solar eclipse was in the late Qing Dynasty. Although food can be seen in Hexi Corridor, Inner Mongolia and Heilongjiang, the longest food was delayed for more than 2 minutes, but it was not officially recorded. Only partial solar eclipse can be seen in Shanghai. French missionaries took the first group of photos of solar eclipse in China at Sheshan Observatory.

On June 1936 and 19, a total solar eclipse occurred on the Sino-Soviet border and northern Japan, with the longest eclipse lasting more than 2 minutes. The Chinese Astronomical Society sent two teams to observe abroad. The team headed by Yu, director of the Institute of Astronomy, Academia Sinica, went to Hokkaido, Japan, and successfully took photos of the corona and solar eclipse films in key periods. Another team went to Boli, Yuzhe Zhang and Hengli in the Soviet Union. Although it was cloudy and the plan failed, I also accumulated some experience.

1941September 2 1 The total solar eclipse belt enters from Xinjiang and passes through Qinghai, Gansu, Shaanxi, Hubei, Jiangxi, Fujian, Zhejiang and other provinces. The longest eclipse lasted more than 3 minutes, and the observation conditions were good. However, at this time, during the difficult period of the Anti-Japanese War, a large area of land fell, and foreign customized instruments could not be transported, and the Institute of Astronomy also moved from Nanjing to Kunming. Even so, the China Solar Eclipse Observation Committee organized two observation teams. The Northwest Team, led by Yuzhe Zhang and Gao Lu, went to Lintao, Gansu Province, and held a photo exhibition of solar eclipse, lectures on popular science and science film along the way, which finally achieved many scientific achievements and filmed the film of solar eclipse. The Southeast Team went to Chong 'an, Fujian, and measured the geomagnetic variation data during the total solar eclipse.

1 February 5, 943, the longest total solar eclipse of1min 40 seconds appeared in the eastern part of Heilongjiang, but it was not observed at that time.

1On the evening of September 22, 968, a total solar eclipse occurred in western Xinjiang, and the longest solar eclipse only lasted for more than 20 seconds. This is the first total solar eclipse in China since the founding of New China. China has organized a large-scale and multidisciplinary comprehensive observation: the Zhaosu observation team in Zhaosu Town, Yili City has carried out optical observation, and the Kashgar observation team in southern Xinjiang has carried out radio observation. In addition, there are geophysical and meteorological sections. Astronomers in China also made the first attempt to observe the solar eclipse on an airplane flying at an altitude of over 1 1000 meters. Generally speaking, this observation has achieved quite gratifying results.

1980 February 16 at about 6 pm, a total solar eclipse occurred in Yunnan, Guizhou and other places, and the longest eclipse was delayed by nearly 2 minutes. The observation conditions such as solar horizon height were much better than those at 1968. At that time, at the beginning of reform and opening up, the scientific community was full of spring. China Academy of Sciences has organized various teams to make optical and radio observations of the sun, measure the ionosphere, geomagnetism and gravity field of the earth, and study the weather changes during the total solar eclipse. The optical observation station is Yingpan Mountain in Ruili County, and the radio observation station is Phoenix Mountain Observatory in Yunnan Observatory. Shanghai Science and Education Film Studio filmed a documentary about the whole process of solar eclipse observation. China Association for Science and Technology also organized middle school students from Beijing and Shanghai to observe the solar eclipse in Yunnan. People in local villages all wore sunglasses. That scene was really touching.

1The total lunar eclipse zone of the solar eclipse on March 9, 997 swept Mongolia from the northern end of Xinjiang, passed the northernmost end of Heilongjiang and ended in the Arctic Ocean. Mohe County is the only city in China located in the total solar eclipse belt. At that time, the height of the sun was moderate, making it the best observation place, and the longest eclipse lasted about two and a half minutes. The eclipse coincided with the world's attention, and comet hale-bopp was also high in the sky. More than 3,000 Chinese and foreign experts and enthusiasts from Taiwan Province, Hongkong and Macau gathered in this small town on the northern border of China, and the observation scene was quite spectacular. CCTV and Heilongjiang TV also broadcast live. The scientific achievements of this total solar eclipse research were later compiled into a book "Total solar eclipse and near-earth environment".

On August 1 day, 2008, Xinjiang and Gansu ushered in the first visible total solar eclipse in China since 2 1 century. Everyone remembers this clearly, so I won't go into details here. After this year, the next total solar eclipse in China, which passes through many large and medium-sized cities, will wait until September 2, 2035. By then, the total solar eclipse belt will enter the sea eastward along Jiayuguan, Baotou, Datong, Beijing and Qinhuangdao, but most of them will last less than 2 minutes. Then on April 30, 2060, the total solar eclipse passed through Aksu, Xinjiang, Xining, Qinghai and ended in Lanzhou. The solar eclipse in China in this century

At 9: 35 am on July 22, 2009, the total solar eclipse in East China lasted for the longest time in nearly a hundred years. The best observation point in China, Zhoushan Langgangshan Island, lasted 6 minutes and 04 seconds, and the best observation point was an island in the Pacific Ocean, reaching 6 minutes and 44 seconds.

In 20 12 years, scientists predict that there will be another total solar eclipse.

A total solar eclipse will occur in China in 2009. Among them, the total solar eclipse on July 22, 2009 was the longest in the past century, reaching 6 minutes and 44 seconds. This total solar eclipse can be seen in Shanghai, Hefei, Suzhou, Hangzhou and other Yangtze River basins, and Tongling is the best observation point. If the weather is fine, we can feel the feeling of suddenly turning black. Some documents point out that if there is a total solar eclipse, if the weather is fine, even the stars in the sky will be observed during the total solar eclipse!

Because the total solar eclipse swept through the densely populated Yangtze River Delta urban agglomeration in China, it attracted much attention.

August 2008 1

The eclipse is divided into 1.039, and the longest duration of the total eclipse is 2 minutes and 27 seconds. It can be seen in northeastern North America, Europe and parts of Asia, including northern Canada, Greenland, Novosibirsk, Mongolia, Xinjiang Uygur Autonomous Region, Gansu Province, Ningxia Hui Autonomous Region, Shaanxi Province, Shanxi Province and Henan Province in China.

In China, considering the sun height, geography, traffic and other comprehensive factors, Jinchang, Gansu Province is a better observation site. The Moon's umbra center will only pass 1 2km north of Jinchang Center, and the total solar eclipse time will be about1min for 45 seconds.
