About the total solar eclipse on July 22nd.

As long as the weather is fine, the total solar eclipse on July 22, 2009 will occur around 9 am, and the total solar eclipse belt will sweep across the following major cities from west to east. People living in these areas will have the opportunity to see the once-in-a-century total solar eclipse for a long time, lasting for 4-5 minutes. It was a long night for the total solar eclipse. Kangding, Ya 'an, Leshan, Chengdu, Zigong, Neijiang, Suining, Nanchong, Chongqing, Dazhou, Qianjiang, Yichang, Jingmen, Jingzhou, Jiangling, Shashi, Kaogan, Xianning, Wuhan, Huanggang, Ezhou, Huangshi, Lu 'an, Hefei, Anqing, Chizhou, Chaohu, Wuhu, Tongling, Huangshan and Xuanzhou. This is a total solar eclipse that can be seen in almost the whole Yangtze River basin, and about 400 million people will see it. After a careful inspection of the above areas, I found that Huangshan Mountain, where I have always wanted to travel, is near the center of the total solar eclipse. Great, kill two birds with one stone. Of course, the Hangzhou Bay Bridge, which passes through the total solar eclipse center, is also a very good choice to watch the total solar eclipse at sea on this nearly 50-kilometer-long cross-sea bridge. The condition of total solar eclipse is that the three celestial bodies, the sun, the moon and the earth, should be just impartial or very close to a straight line. This kind of opportunity can only be seen once every three or four hundred years for the same observation point, and the longest time when the sun is completely covered will not exceed 7 minutes 4 1 second. When observing the total solar eclipse, special or homemade equipment must be used. It is forbidden to observe the sun directly with the naked eye, so as not to cause harm to the eyes.

If you don't know how to observe the total solar eclipse, it is very dangerous to observe it, because the sun emits strong visible light, infrared light and ultraviolet light. Ultraviolet rays not only burn the skin, but also cause rapid damage to the retina of the eyes. As long as human eyes look directly at the sun for a few seconds, it may cause permanent damage or even blindness. If the sun is observed through a telescope without proper dimming equipment, the consequences will be even more unimaginable.

Partial solar eclipse and annular solar eclipse can't be watched without special safety measures. In the partial eclipse stage of the total solar eclipse, even if the surface of the sun is covered by the moon for 99%, the photosphere formed by the new moon will still cause harm to the eyes. Don't try to observe the sun in any partial solar eclipse, annular solar eclipse or partial solar eclipse with naked eyes.
