 The golden ring eclipse will come on the stage tomorrow afternoon. The next observation in China will be until 2030


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

Golden ring eclipse is the image 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.

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.

Take Xiamen City, which is located in the annular eclipse zone, as an example. The time of the annular eclipse (0.99) can be seen in different places in Xiamen city will be slightly different. If you know your specific location, the time can be accurate to the order of seconds. For example, in Xiamen railway station, the initial loss time is 14:43:37 Beijing time, the eclipse time of the moon just entering the solar area is 16:10:17, the eclipse time is 16:10:46, the luminous time of the moon just leaving the solar area is 16:11:14, and the recovery time is 17:24:12. Another example is Tiananmen Square in Beijing, which is located outside the ring eclipse zone. You can see the partial eclipse (the eclipse is 0.59), the initial loss time is 14:33:25, the even time is 15:50:20, and the circle time is 16:58:47.

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.

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.
