Total solar eclipse and annular solar eclipse are both kinds of solar eclipses. On June 2, 2020, a rare annular solar eclipse was conducted. Will there be a total solar eclipse in 2020?

Will there be a solar eclipse from June 5438 to February 2020? Yes, there will be an annular eclipse.

What date is the total solar eclipse in 2020: 65438+February 15 00: 17.

In 2020, there will be a total solar eclipse and an annular solar eclipse on the earth. The only total solar eclipse in 2020 will occur at midnight on February 15, Beijing time. However, the only continent that the total eclipse belt of this total solar eclipse crosses is South America, and it takes the whole earth to catch up with this total solar eclipse.

In 2020, it can be seen that the annular solar eclipse occurred at 5438+0 on June 26th, Beijing time, that is, the day of summer solstice. The annular eclipse belt spans Asia and Africa, starting from the Democratic Republic of Congo and northern China, passing through Central Africa, South Sudan, Ethiopia, Eritrea, Red Sea, Yemen, Saudi Arabia, Oman, Pakistan, India and China, and ending in the western North Pacific.

Partial solar eclipse can be seen in Africa (except the west and south, Southeast Europe, Asia (except the north and southeast poles, the northern Indian Ocean, the northwestern Oceania and the western North Pacific). Among them, the circular food belt passes through China, Tibet, Sichuan, Guizhou, Hunan, Jiangxi, Fujian, Taiwan Province and other provinces. In these areas, the annular eclipse will be visible in the annular eclipse belt, and the partial eclipse will be visible in other areas.

Observation condition

1. It must be in the center of the total solar eclipse.

2. The total solar eclipse lasts more than 3 minutes.

3. The weather is fine.

Observation (Tips: Don't directly observe the sun with naked eyes.

Ink observation method

You can take a basin of water, add ink, and see the sun through the reflection of water. This method is not recommended because of its low dimming rate and easy eye injury.

Pinhole projection method

Make use of two boards, dig a small hole in one board, and let the sunlight pass through this small hole and project onto the other board.

telescope projection method

Don't shake your hands, or the shadow of the sun will shake. And don't look at the sun directly with binoculars, otherwise your eyesight may be damaged.

Total solar eclipse schedule in 2020 When is the next total solar eclipse in China?

When there is a total solar eclipse, the sunlight on the earth will be blocked by the monthly amount. The last total solar eclipse in China was on July 22nd, 2009. Do you know the total solar eclipse time in 2020? When is the next total solar eclipse in China? Let's reveal the constellation knowledge for everyone! Let's have a look!

Schedule of total solar eclipse in 2020: June 2 1, 06:4 1: 15, annular eclipse, 137, 0.994000m 38s, Africa, Southeast Europe, Asia [Eclipse: Central Africa, South Asia, Total Eclipse]

When is the next total solar eclipse in China? The next visible total solar eclipse in China is on March 20th, 2034, but it is only visible in a small part of Tibet, which is basically a no-man's land. China will not be able to see the total solar eclipse until September 2, 2035. The observation conditions are very good, and its total solar eclipse belt will pass through the northwest, north China and Beijing, and enter the sea eastward.

How often does the total solar eclipse occur? First of all, it is not always possible to see a total solar eclipse. The diameter of the sun is about 400 times that of the moon. Therefore, only when the orbits of the sun and the moon "meet" and the distance between the sun and the earth is at least 400 times that of the sun and distance to the moon, can the moon completely block the direct sunlight of the sun and form a total solar eclipse. In terms of the number of global occurrences, there are actually more solar eclipses than lunar eclipses in a year. From the earth's point of view, the orbit of the sun and the moon runs once every six months, and the possible periods of solar eclipse are overlapping (the eclipse season is even longer than the period of lunar eclipse (there is not necessarily an eclipse in a year, but there will be two to five eclipses). But once a lunar eclipse occurs, it can be seen by half of the earth in the dark. The total lunar eclipse can last for tens of minutes or even hours, and the observable range and duration are much longer than that of the total lunar eclipse, so it is in the same place. On a global scale, the total solar eclipse occurs once every 1.5 years on average.

When will there be an annular eclipse in 2020, and see if it happens during the day or at night?

Among the many astronomical phenomena in 2020, the most interesting thing is the annular solar eclipse in 2020. This annular solar eclipse is partially visible in China, and it is worth watching. Then let's use constellation knowledge to reveal when there will be an annular eclipse in 2020. Does it happen during the day or at night?

Q: When will there be an annular solar eclipse in 2020? A: On June 2, 20201day, you can see the annular solar eclipse.

Q: Does the annular eclipse occur during the day or at night? Answer: The annular eclipse occurs during the day.

On the afternoon of June 2 1 2020, there will be a spectacle of annular eclipse. The annular eclipse belt will enter from Mabangyong, the holy lake in Tibet, pass through the south of Sichuan Basin, enter Fujian through the northeast of Guizhou and the south of Hunan and Jiangxi provinces, enter the sea in Xiamen, Fujian, and finally leave China through Taiwan Province Island. In addition to the annular eclipse belt, partial solar eclipse can be seen in other parts of the country. Because the annular eclipse belt is thin, it "cleverly" avoids all the urban areas except Zhangzhou, Xiamen, and many friends who want to enjoy the wonders of the golden ring may have to bother more.

Principle of annular eclipse: The essence of annular eclipse is actually because the moon is far away from the earth, and the umbra of the moon cannot reach the ground, and its extension line passes through the ground, but people who are located in the extension line of the umbra of the moon can see the annular eclipse. If the moon is close to the earth, the shadow of the moon can reach the ground, and people in the shadow will see the total solar eclipse. Annular eclipse is also related to the earth and the moon itself. Because both the earth and the moon are opaque spheres, the sun shines and is sometimes blocked by the moon. An annular eclipse may occur on the first and second day of the lunar calendar. On these days, if the earth, the moon and the sun are on the same straight line, an annular eclipse will occur. The light from the sun is blocked by the moon. In the shadow area of the moon, people can't receive the sun, so they can't see it. Moreover, because the distance between the moon and the earth is different from that between the moon and the sun, and the distance between the moon and the sun is much greater than that between the moon and the earth, the moon covers the sun and only exposes a part around it, thus forming an annular eclipse.

When and where will the annular solar eclipse in China in 2020 occur?

Annular eclipse is one of the most anticipated astronomical phenomena this year. Annular eclipse can be seen in many places in China, but partial eclipse can be seen in some places, so let's use constellation knowledge to reveal the position of annular eclipse in 2020. When will our country start?

Location of annular eclipse in 2020: China, Tibet, Sichuan, Guizhou, Hunan, Jiangxi, Fujian, Taiwan Province and other places.

When will the annular solar eclipse begin in China in 2020? On June 2 1 day, 2020, the penumbra of the moon entered the Ali region of China, Tibet around 10: 56. End time: 15: 37 After that, the penumbra of the moon left China from Hainan Province.

According to the forecast of Nanjing Purple Mountain Observatory of Chinese Academy of Sciences, in 2020, that is, on June 2 1 this year, there will be an "annular eclipse" passing through China. At that time, astronomy enthusiasts in Tibet, Sichuan, Guizhou, Hunan, Jiangxi, Fujian, Taiwan Province and other places will have the opportunity to see the wonders of the annular eclipse.

Of course, there are still half a year to make full preparations. Solar eclipse is actually a common phenomenon. Some people may not understand the concept of annular eclipse. Annular eclipse is also a kind of solar eclipse, but it is more demanding.

We know that the moon orbits the earth in an elliptical orbit, so the distance from the moon to the earth is changing. According to the position of the moon shadow, the eclipses observed by observers can be divided into three categories: partial eclipse, total eclipse and annular eclipse. When the moon moves between the earth and the sun, if the three are in a straight line, the moon will block the light that the sun shines on the earth. The phenomenon that the sun is partially or completely blocked by the moon is called an eclipse.

In fact, the essence of annular eclipse is that the moon is far away from the earth, and its umbra cannot reach the ground, but its extension line passes through the ground, and people located in the extension line of the umbra of the moon can see the annular eclipse. At this time, from the visual effect, the moon is smaller than the sun, so when you look at the sun from the pseudo-umbra, you can see a halo with the center blocked and the surrounding light blocked, that is, an annular eclipse. If the moon is close to the earth, the umbra of the moon shadow can reach the ground, and people under the umbra will see the total solar eclipse.

Fortunately, we can still see a wonderful annular eclipse after half a year. This annular food belt will start from the Democratic Republic of Congo and northern China, pass through Central Africa, South Sudan, Ethiopia, Eritrea, Red Sea, Yemen, Saudi Arabia, Oman, Pakistan, India and China, and end in the western North Pacific. In China, the annular eclipse belt will pass through China, Tibet, Sichuan, Guizhou, Hunan, Jiangxi, Fujian and Taiwan Province provinces. People in these areas can enjoy the wonderful annular solar eclipse, while only partial solar eclipse can be seen in other places.

From the astronomical observation point of view, the observable phenomenon of annular eclipse is much less than that of total lunar eclipse, because the sunlight is not completely blocked, and many phenomena such as chromosphere, corona and Bailey bead are difficult to observe. However, in the annular eclipse stage, especially when the eclipse is very heavy, the central part of the sun is dark, and the edge is still bright, turning into a golden flashing ring, which is also a deep visual shock. Due to the occlusion of the moon, the outer layer of the sun, which was originally difficult to observe, can be exposed, which is of great significance to solar research. Scientists will also observe through radio bands. Even partial solar eclipse and annular solar eclipse can get important information about chromosphere and corona atmosphere and local radio sources, so annular solar eclipse is a rare experience for people or scientists!

Finally, of course, it is the main observation point. When observing the annular eclipse, we must pay attention to safety. We must wear special observation glasses or choose suitable filters to observe the solar eclipse. Although the solar eclipse is partially blocked by the sun, the sunlight is not very dazzling, but the light emitted by 1% of the solar area is even brighter than the light emitted by welding. If you look directly at the sun for a little longer, it will lead to macular burn and produce "solar retinitis". Once burned, the macula of the retina will never recover. You may not feel anything when you are injured, but you will have adverse reactions after a few hours, and you will be permanently blind in serious cases. Therefore, don't take chances, safety is the first thing to observe, and you can't observe directly with the naked eye.
