According to astronomical experts, on April 20, Tianyu will stage a special solar eclipse - the total annular eclipse. A partial solar eclipse with very small eclipse points can be seen in Hainan, Guangdong, Fujian, Taiwan and a few other regions in China.
The solar eclipse, also called solar eclipse, occurs when the moon moves between the sun and the earth in a straight line.
Total solar eclipse, annular solar eclipse and partial solar eclipse are three types known to the public. What does the total annular solar eclipse mean?
According to Yang Jing, member of the Chinese Astronomical Society and director of the Tianjin Astronomical Society, In the same solar eclipse, if a total solar eclipse is visible in some areas and an annular solar eclipse is visible in other areas, it is called an annular solar eclipse, also known as "mixed eclipse" and "compound eclipse", which is very rare.
In the 21st century, for example, only seven total annular eclipses have occurred in the past 100 years.
This year's solar eclipse has a very narrow eclipse belt. There will be a birthday annular eclipse at both ends of the belt, and a total solar eclipse in the middle.
The solar eclipse belt starts from the south of the Indian Ocean, passes through Exymouth, Australia, southeast of East Timor, Papua Province, Indonesia, and ends in the western Pacific Ocean.
Unfortunately, only a few regions in China can see a partial solar eclipse "eaten" by the moon. These regions are limited to the land and islands in the extreme southeast, including the coastal areas of Zhejiang, Fujian and Guangdong, and a few regions such as Hainan, Hong Kong, Macao, Taiwan, the East China Sea and the South China Sea.
In addition, experts remind that when watching the solar eclipse, Never observe directly with the naked eye, nor use daily sunglasses or sunglasses. You should wear special sunglasses to observe the sun, And watch more than ten seconds will have a rest, to prevent eye injury.
