Find the total solar eclipse coverage area on the 22nd!

Only the northernmost counties will be able to see the total solar eclipse, see the area between the red lines in the map.

A total solar eclipse will be visible in Longshan County in the northwest, and the time is detailed in details.

When observing a total solar eclipse, you should choose an area with sunny days as much as possible, and you should pay attention to eye safety. Because sunlight is a million times stronger than moonlight, it cannot be directly ** with the naked eye or through a telescope without light-reducing equipment, otherwise it is easy to cause retinal damage and even blindness. During a partial solar eclipse, it is safer to wear a pair of total eclipse goggles or to use a basin of ink with ink to pass through the reflection**.

When observing with a telescope, be sure to add a filter in front of the eyepiece or detector to avoid burning your eyes.

Chengdu, Chongqing, Wuhan, Hefei, Tongling, Tongcheng, Huangshan, Gaochun, Changzhou, Suzhou, Wuxi, Shanghai, Jiaqing, Hangzhou are the best places to observe

The most exciting total solar eclipse is from 9 a.m. to 9:38 a.m. (Beijing time) on July 22, and the longest duration of this eclipse is 6 minutes. The Moon's umbra will cover eastern Asia, the Pacific Ocean and Hawaii.

This solar eclipse is the longest total solar eclipse of the 21st century, and will be visible in the Chinese cities of Tongcheng, Chengdu, Leshan, Chongqing, Yichang, Wuhan, Wuhu, Tongling, Shanghai, Jiaxing, Wuxi, Suzhou, Ningbo, Hangzhou, Jingzhou and other places.

In other provinces, only the sun is partial.

Hehe, that's what can happen if you look directly at a solar eclipse with your eyes.

At the end of the day, it's our eyes. It's something called rhodopsin.

The rhodopsin that decomposes in the light can be resynthesized in the dark, that is, it is a reversible reaction, and the equilibrium point of the reaction depends on the intensity of the light. When we look at the sun, rhodopsin in some retinal cells is over-decomposed by bright light, but relatively little on the surrounding cells, so it creates an illusion. When we are in the dark, the areas of rhodopsin that are over-decomposed have not yet had time to synthesize, and the rhodopsin synthesis of surrounding cells is relatively fast, so the illusion still exists.

It has the greatest absorption capacity for blue light, which is consistent with the fact that the human eye perceives the blue-green region of the spectrum (equivalent to around 500 nm wavelength) brightest (not blue-green) in low-light conditions.

Under normal circumstances, the time for people to stare at the general bright light is a few minutes, but the adaptation time from the sun to the dark place is more than 20 minutes, which is caused by the different rates of rhodopsin decomposition and synthesis.

Relevant information.

Your eyes may be delusional.

Maybe you have another identity, hehe

Hehehehehe, it's normal, I've had it, it's just that it's not the same as you, and when you see the dazzling light, the research will have an indescribable vague hallucination, just like I look at the light now, a few seconds later, I'm looking at the wall, and then something appears on the wall, in fact, I don't know what it is, anyway, it's normal, good manuscript, don't make a fuss, youmae Xiao.

As long as the weather is fine 2009

The total solar eclipse on July 22 will occur around 9 a.m., and the total eclipse belt will sweep from west to east over the following major cities. Those who live in these areas will have the opportunity to see a once-in-a-century ultra-long total solar eclipse lasting 4-5 minutes, which is a long dark night for a 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, Xuanzhou, Ma'anshan, Huzhou, Changzhou, Wuxi, Suzhou, Hangzhou, Jiaxing, Shaoxing, Shanghai, Ningbo, Zhoushan.

This is a total solar eclipse that will be visible to almost the entire Yangtze River basin, and about 400 million people will see it. I carefully checked the above area and found that Huangshan, the place I have always wanted to travel, is near the center of this total solar eclipse, which is great, killing two birds with one stone. Of course, the Hangzhou Bay Bridge in Hangzhou, the center of the total solar eclipse just passed, and it is also a very good choice to watch the total solar eclipse on this nearly 50-kilometer-long sea-crossing bridge.

A total solar eclipse occurs when the Sun, the Moon, and the Earth are three bodies that are blue and square, just right or very close to each other in a straight line. This kind of opportunity can only be seen once in three to four hundred years on average for the same observation point, and the maximum time the sun is completely obscured will not exceed 7 minutes and 41 seconds. When observing a total solar eclipse, be sure to use special or homemade equipment, and it is strictly forbidden to observe the sun directly with the naked eye, so as not to cause damage to the eyes.

It is dangerous to observe a total solar eclipse if you do not know how to observe it, because the sun emits intense visible light, infrared light and ultraviolet light. Not only can UV light cause sunburn**, it can also cause rapid damage to the retina of the eye. As long as the human eye is directly exposed to the sun for a few seconds, it can cause permanent damage or even blindness.

If you look at the sun through a telescope without proper dimming equipment, the consequences are even more dire.

Partial solar eclipses and annular solar eclipses cannot be taken without special safety measures**. During the partial eclipse phase of a total solar eclipse, even though the surface of the Sun is 99% obscured by the Moon

, the remaining light sphere formed by the crescent moon can also cause damage to the eyes. Do not attempt to visually observe the nucleus of any partial solar eclipse, annular eclipse phase, or partial eclipse phase of a total solar eclipse.

In the coming December, Tianyu will stage a rare celestial drama. According to the latest astronomical forecast, on December 21, a wonderful total lunar eclipse will appear in the sky. Astronomical experts said that although the Chinese public could not witness the whole process of the total lunar eclipse, the "penumbral lunar eclipse", "rounding process" and "eclipse out" could be seen in some areas.

According to astronomical experts, according to the latest astronomical forecast, the total lunar eclipse on December 21 will lose at 14:32 Beijing time, and the lunar eclipse will officially begin, and at 16:53, the moon will begin to leave the earth's shadow. There is no lunar eclipse in the far west of China, only the end of the penumbral eclipse can be seen in the central and western regions, the gradual re-rounding process of the lunar eclipse after the end of the total eclipse can be seen in the central and southeastern regions, and the total eclipse of the moon belt can be seen in the northeast region.

This lunar eclipse is an excellent time for people to watch the lunar eclipse and engage in astronomical science activities. Astronomical experts said that for the Chinese public, although they cannot witness the whole process of the total eclipse, it is also good to be able to enjoy the "moonrise with eclipse", so the interested and qualified public must not miss this opportunity.

There are three types of lunar eclipses: penumbral lunar eclipses, partial lunar eclipses, and total lunar eclipses. The middle part of the Earth's shadow is called the umbra, and around the umbra is the penumbra. A penumbral lunar eclipse occurs when the Moon enters the Earth's penumbra, a partial lunar eclipse occurs when a part of the Moon enters the Earth's umbra, and a total lunar eclipse occurs when the Moon enters the Earth's umbra.

Like solar eclipses, lunar eclipses occur almost every year, but some eclipses are not observable in a given area because they do not necessarily occur at night.

The total lunar eclipse on December 21 will be visible in eastern Asia, most of Oceania (except western Australia), the Arctic Ocean, the Pacific Ocean, North America, South America, the North Atlantic, the western South Atlantic, western and northern Europe, and the northwest tip of Africa.

It is understood that when a total lunar eclipse occurs, the area where the moon is located, the sun's light cannot be directly illuminated at all. However, through the Earth's atmosphere, there will still be a little sunlight refracted into the Earth's shadow, so that from the Earth, the Moon does not disappear from the sky, but takes on a rare bronze color, which is commonly referred to as the "Red Moon".

On December 21, 2010, there was a total lunar eclipse in the afternoon of Beijing time, and most of China was not in the best observation area for this total lunar eclipse, because the lunar eclipse began at about 1:30 p.m. Beijing time, and the moon will not rise until about 4:50 p.m., and the eclipse has passed at this time. If the weather is fine on a sunny day, find a place with a higher altitude and a wider view of the east to see the eclipse moon after 4:50. For most parts of China, the overall conditions for observing the total lunar eclipse are not very good, and if you want to observe this complete lunar eclipse, you can go to eastern Russia or the North American continent.

Some places have it, some places don't.
