The 16 day annular eclipse occurred in 20 years can only be seen three times in China

According to Wang Huijuan, a researcher of the nebula program at the National Astronomical Observatory of the Chinese Academy of Sciences, when the moon moves between the sun and the earth, and the three are approximately in a straight line, an eclipse will occur. Because the orbit of the moon around the earth is elliptical, sometimes it is closer to the earth, it looks big, sometimes it is farther away from the earth, it looks small. When the moon is relatively close to the earth, the total solar eclipse can completely cover the sun; when the moon is relatively far away from the earth, the moon can not completely cover the sun. When a total eclipse or an annular eclipse occurs, a partial eclipse can be seen in some areas outside the total eclipse zone or the annular eclipse zone. In addition, the partial eclipse can also occur alone.

Golden ring eclipse is the image name of the annular eclipse, because when you eat, you will find a very bright edge around the blocked part of the sun, like a ring. The eating utensils around the sun have strong ornamental value, the visual shock degree is second only to the total solar eclipse, and different from the total solar eclipse.

The golden ring solar eclipse itself is not uncommon. For example, there will be a 16 day annular eclipse in the 20 years 2011-2030, but only three times can be seen in China. The most recent one is June 21, the last one is May 20, 2012, and the next one will be June 1, 2030. Wang Huijuan said.

Considerable partial eclipses outside the circumsolar zone, such as Beijing

On December 26 last year, the annular eclipse also appeared in the sky, but at that time, only partial eclipses of different degrees could be observed in China. Can Chinese astronomers watch the annular eclipse this time?

Wang Huijuan said that the annular eclipse belt passes through Africa, Asia and the Pacific, central Tibet, South Central Sichuan, northeast Guizhou, southwest Chongqing, South Central Hunan, South Jiangxi, South Fujian and South Central Taiwan in China. If the weather is clear, we can see the annular eclipse in the area of the annular eclipse zone, and we can see the partial eclipse outside the annular eclipse zone. For example, the public in Beijing can see partial solar eclipse.

The closer to the central area of the annular eclipse zone, the finer the golden ring

Is the thickness of gold ring different from place to place? Wang Huijuan explained that the degree of eclipse is the ratio of the covered part of the diameter of the solar surface to the diameter of the sun. The bigger the food, the finer the gold ring. However, for the same annular eclipse on the next day, the difference of food score in the annular eclipse zone is very small, and it is difficult to detect the difference of ring thickness seen in different places.

The time of the golden ring eclipse is on the afternoon of June 21, 2020 Beijing time. The specific time of each region is slightly different. The public can query the specific time of the eclipses initial loss, existing food, even food, light and recovery on the website of Chinas national astronomical science data center.

Wang Huijuan said that the area located in the annular eclipse zone and sunny during the solar eclipse is the best observation site. If the weather is clear in Beijing, you can watch a partial solar eclipse with an eclipse of about 0.6, and the effect is very good.

u25a0 viewing strategy

Bud film must be installed before camera shooting

Naked eyes can be viewed through special sunglasses. If you shoot with a mobile phone, you must install a 3.8 or 5.0 density Bader film in front of the lens of the mobile phone.

In addition, pay attention not to keep your eyes on the sun for too long, and take a rest for 2-3 minutes. In addition, it can also be observed by the projection of the sun through the leaves on the ground, or by the principle of small hole imaging.
