Can Anhui see the total solar eclipse on August 1 2008?
This is the first total solar eclipse in China in the new century. The total solar eclipse starts from northern Canada, passes through the Arctic Circle, Russia and Mongolia, and will enter China through Altai Mountain at 18: 59 Beijing time. It passes through Xinjiang, Gansu, Inner Mongolia, Ningxia, Shaanxi and Shanxi, and stops at Luohe, Henan at sunset (Beijing time 19: 2 1).
Because the total solar eclipse lasts for a short time in a certain area, the longest is only 7 minutes and 30 seconds, so good weather conditions are extremely important for total solar eclipse observation. According to experts' analysis, in August, Hami area and Jiuquan area were almost unaffected by monsoon climate due to the blocking of mountains, with less clouds and scarce rainfall. During the day, the average temperature is above 20℃, the maximum wind speed is only 25 km/h, and sandstorms hardly occur. The climate is extremely dry and sunny. Therefore, Hami and Jiuquan in China are the best places to observe the solar eclipse.
On July 22nd, 2009, a total solar eclipse will occur in a large area of the Yangtze River valley in China. After the total solar eclipse belt entered China from Tibet, it swept Yunnan, Sichuan, Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Zhejiang and other provinces for 5 to 6 minutes. But the next total solar eclipse will be in 25 years. Experts estimate that a total solar eclipse will occur near the border between Xinjiang and Tibet in 2034. In 2035, the total solar eclipse belt will pass through northern cities such as Beijing, Datong and Qinhuangdao.
The so-called eclipse refers to the phenomenon that the sun is blocked by the moon when the moon moves between the sun and the earth. The ancients once described the solar eclipse as "dogs eat the sky". In fact, the eclipse process is more like a shielding process in which a circular plate moves from one side of the sun to the other.
During the solar eclipse, people on the ground in the center of the moon shadow see a total solar eclipse or an annular solar eclipse; People in the penumbra of the moon see a partial solar eclipse. Experts say that although there are two total solar eclipses in the world every two or three years, it takes hundreds of years on average to see a total solar eclipse in any particular place, and each total solar eclipse lasts only a few minutes at most.
A classic observation project can be carried out during the total solar eclipse, which is to verify the deflection of light predicted by Einstein's general theory of relativity in the solar gravitational field. The method is to take photos of the black sun and its surrounding stars, and then compare them with photos taken at night half a year ago or half a year later to see if the angular distance of these stars has changed. If gravity causes light to deflect, the starlight passing through the sun will change direction slightly.
