According to the National Astronomical Observatory, on the morning of July 22, the astronomical wonder of a total solar eclipse will be seen across the Yangtze River valley, and a partial solar eclipse will be seen in other areas. The partial solar eclipse will last more than two hours in Beijing and 72.9 percent of the sun will be obscured.

According to calculations made by the National Astronomical Observatory, the partial eclipse will begin at 8:25 am, peak at 9:32 am, and end at 10:44 am.

Zhao Gang, the vice director of the National Astronomical Observatory, said that a total solar eclipse can only be seen from the Yangtze River valley, while partial solar eclipses of varying degrees will be seen from other parts of China. "If sunny, the sky in Beijing will become slightly dark, but only slightly." He added that, if people would like to watch the eclipse, they must be well prepared with observation equipment and not look with the naked eye.

Su Yi, director-general of Tianjin Astronomical Society, and professor from Nankai University, described vividly how the sun in Beijing and Tianjin will resemble a crescent moon, while the sky will not be completely dark.

Tips for observation

Total solar eclipse will cause a temperature drop of 10 degrees Celsius

Kou Wen, a senior engineer from Beijing Planetarium, said that, from past experience, a total solar eclipse will cause a temperature drop of 10 degrees Celsius or more, and watchers should bring long-sleeved clothes to cope. In Beijing, the sun will only be partially obscured, and the temperature will only drop slightly.

Never wear sunglasses to observe

According to Hao Jinxing, vice director and researcher of the National Astronomical Observatory, a whole solar eclipse takes as long as several hours, but the sun will only be fully obscured for about five minutes, outside of these five minutes, it cannot be observed with the naked eye.

For regions experiencing a total solar eclipse, special observation equipment will be needed before and after the sun is fully obscured, and in partial solar eclipse regions, equipment will be needed all the way through. Never observe through sunglasses. When the sun is fully obscured, during these several minutes, people can watch with the naked eye.

The Live Show can be watched on the Internet and TV

On July 22, some websites and TV stations including CCTV and local satellite TV, will broadcast the solar eclipse live. Audiences can watch the broadcast on the Internet and TV.
