You are referring to the total solar eclipse on July 22nd.

This total solar eclipse cannot be seen in Chaozhou. The areas that can be seen are mainly the Yangtze River Basin, including southeastern Tibet, northwestern Yunnan, Chongqing, Sichuan, Hubei, northern Hunan, Anhui, northern Jiangsu, southern Jiangsu, northern Zhejiang, and Shanghai.

But don’t despair, there will be a live broadcast online.

As for the time, each place is different. For example, in urban Shanghai, the solar eclipse will officially kick off from 8:23 am on July 22. From 9:36 to 9:41, Shanghai residents can enjoy it for about 5 minutes.

The total solar eclipse will last for more than two hours and will not end until 11:01.

Astronomy enthusiasts can go to Yangshan Deepwater Port for observation. This area is the longest total eclipse observation point accessible from land in China. The total eclipse lasts from 9:37:32 to 9:43:29, lasting 5 minutes and 57 seconds.

In addition, you cannot watch the total solar eclipse directly.

The following are Baidu's precautions for observing a total solar eclipse. Observing the sun is very dangerous because the sun emits strong visible light, infrared and ultraviolet light.

Ultraviolet light can not only sunburn the skin, it can also quickly cause damage to the retina of the eyes.

Just looking directly at the sun for a few seconds can cause permanent damage or even blindness.

If you observe the sun through a telescope without proper light reduction equipment, the consequences will be even more disastrous.

Partial solar eclipses and annular solar eclipses cannot be viewed without taking special safety precautions.

During the partial eclipse phase of a total solar eclipse, even when the sun's surface is 99% obscured by the moon, the remaining photosphere formed by the new moon can cause damage to the eyes.

Do not attempt to observe the Sun with the naked eye during any partial or annular eclipse phase.

If you look directly like this without using professional equipment, it is likely to cause permanent vision loss.

Especially when the total solar eclipse is about to end, if you look directly at it with the naked eye, the strong sunlight will cause damage to your eyes. Therefore, in addition to using professional astronomical telescopes to watch the total solar eclipse, ordinary citizens must wear special sun protection glasses.

For drivers, don’t forget to drive safely during the few minutes the total solar eclipse lasts. If you want to watch the total solar eclipse, it’s best to pull over and turn on the double-jump lights. Don’t watch it while driving.

Here are some scientific observation methods: 1. Ink observation method (however, this method has a low light reduction rate and can easily hurt the eyes, so it is not recommended). You can take a basin of water, add ink, and look at the sun through the reflection of the water surface.

2. Pinhole projection method: Use two boards, dig a small hole in one of the boards, and let the sunlight pass through the small hole and project onto the other board.

3. Telescope projection method: Don’t move your hands around, otherwise the shadow of the sun will run back and forth.

And never look directly at the sun with a telescope. If you use a telescope to look at the sun directly, be sure to use a filter.

Note: Never use the so-called "Sun Card", "Solar Eclipse Card", etc. provided by informal institutions.

When photographing a solar eclipse, be aware that if you point the lens directly at the sun for a long time, it is easy to burn out the shutter curtain and then burn out the photosensitive element, so you must prepare a color filter in advance.

For multiple exposures, the exposure of each photo must be strictly calculated to prevent overexposure. If it is evening, the light pollution in big cities must be taken into consideration.

PS: On May 21, 2012, an annular solar eclipse was staged again. It can be seen in Guangdong, and of course it can be seen in Chaozhou.
