Can Fushun see the total solar eclipse

You can see a partial solar eclipse in our city.

On July 22nd, a once-in-a-lifetime total solar eclipse will be well observed in the Yangtze River valley of China. The total solar eclipse belt covers a large population, which is an excellent opportunity to solve the unsolved mystery of the sun and popularize astronomical knowledge. According to the data provided by Purple Mountain Observatory of Chinese Academy of Sciences, for Liaoning 14 city, there is a partial solar eclipse, and Dalian has the largest solar eclipse area, accounting for 69.34%, and the best observation time is 9: 40 on the 22nd. The solar eclipse area in Fushun is 57.86%, and the best observation time is 9: 43. Recently, the author visited researcher Jing Hairong, secretary general of Beijing Astronomical Society and deputy director of Beijing Planetarium, and asked him to express his views on the opportunities brought by the total solar eclipse to observe and study the sun.

Many big cities are in the whole food belt.

The total solar eclipse on July 22 has attracted much attention, and its width, time and population passing through the area are rare. The only thing I am not sure about is the weather in the total solar eclipse area. Jing Hairong suggested that friends who want to enjoy the total solar eclipse should always pay attention to the weather forecast and choose the observation site. This total solar eclipse basically occurred in the Eastern Hemisphere, starting from India, passing through Nepal, Bangladesh, Bhutan and Myanmar and entering China. The total lunar eclipse belt passes through eastern Xizang Autonomous Region, northwestern Yunnan, Sichuan, Chongqing, Hubei, northern Hunan, Anhui, northwestern Jiangxi, southern Jiangsu and northern Zhejiang, and enters the sea in Shanghai, the largest city in China. After that, the total solar eclipse belt will pass through southern 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, and the total solar eclipse in the Pacific Ocean was the longest, reaching 6 minutes and 39 seconds. The total solar eclipse can be seen for more than 4 minutes in most parts of the total solar eclipse belt in China. According to rough statistics, there are 300 million people in the area where the total solar eclipse belt passes. Chengdu, Chongqing, Wuhan, Hangzhou and Shanghai are all in the total solar eclipse zone, which is an ideal choice for tourism in the observation zone.

Observation has important scientific value.

The observation of solar eclipse is not only spectacular and shocking, but also of great scientific significance, especially the observation of total solar eclipse. First of all, when the total solar eclipse occurs, the sun chromosphere and corona layer, which are rarely seen at ordinary times, appear directly in front of us, providing astronomers with excellent research opportunities. Through research, we can get a lot of valuable information about the sun, understand the composition, temperature and structure of the solar atmosphere, and the activities of the sun. For example, as early as 1605, Kepler discovered that there would be weak light around the sun during a total solar eclipse. 1706, Cassini, director of the Paris Observatory in France, called this light "corona". Through many observations of solar eclipses, astronomers finally proved that the corona is a real part of the solar atmosphere. In addition, by studying the solar spectrum, scientists confirmed the status of helium as a newly discovered element on the earth.

Jing Hairong believes that observing the total solar eclipse has important scientific value, and its occurrence can provide a good opportunity for studying the relationship between the sun and the earth. There is a close relationship between the sun and the earth. When there is strong activity on the sun, its far ultraviolet rays, X-rays and particle radiation will be enhanced, which will disturb the earth's magnetic field and ionosphere and produce a series of geophysical effects such as magnetic storm, aurora disturbance and short-wave communication interruption. During the total solar eclipse, various geophysical phenomena occurred because the moon gradually covered various radiation sources on the surface of the sun. Therefore, it is of practical significance to observe and study various related geophysical effects during the total solar eclipse. Observing and studying the total solar eclipse is also helpful to study many topics related to astronomy and physics.

Using the opportunity of total solar eclipse, we can find the nearest stars and planets in the orbit of mercury; We can measure the bending of starlight when it passes near the sun, thus testing the general theory of relativity and studying the nature of gravity. We can study the properties of interplanetary dust near the ecliptic; Can study the optical, structural and chemical properties of the earth's atmosphere; You can study the effects of biological clocks on living things. In a word, the scientific observation of the total solar eclipse can greatly deepen our understanding of the world, and also greatly promote the development of other related disciplines.
