How is the golden ring food formed?

Golden annular eclipse is a kind of solar annular eclipse, because the moon is between the sun and the earth, but it is far from the earth and cannot completely cover the sun. Here's what I did for you. I hope it works for you.

The eclipse stage of the golden ring eclipse;

1. Initial loss. The moon moves faster than the apparent speed of the sun. The moon caught up with the sun during the eclipse. When the eastern edge of the moon just "touches" the western edge of the sun, it is called the first loss, which is the first "circumscribed" and the beginning of the solar eclipse.

2. Eat well. About an hour after the initial loss, the moment when the eastern edge of the moon and the eastern edge of the sun "cut in" is called a lunar eclipse, which is the beginning of a total solar eclipse or annular eclipse. For a total solar eclipse, the moon covers the whole sun at this time, while for an annular eclipse, the sun begins to form a ring. During the eclipse, the positional relationship between the shadow of the moon and the first inscribed circle of the sun also refers to the moment when this positional relationship occurs.

The eclipse occurred after the initial loss. From the initial loss, the moon continued to move eastward, the part of the sun's circular surface covered by the moon gradually increased, and the intensity and heat of sunlight decreased obviously. When the eastern edge of the moon surface is inscribed with the eastern edge of the sun surface, it is called eclipse. The direction of the sky is opposite to that of the map.

3. Eat a lot. It is the deepest eclipse moment of the sun, and the center of the moon moves to the center closest to the sun; In the process of partial solar eclipse, when the sun is covered by the moon the most, the positional relationship between them; In the process of total solar eclipse and annular solar eclipse, when the sun is completely covered by the moon and the distance between the two centers is the closest, the positional relationship between them. It also refers to the moment when the above positional relationship occurs.

4.light. The moment when the western edge of the moon and the western edge of the sun "cut in" is called light, which is the end of the total solar eclipse; Generally, an eclipse lasts only two or three minutes, and the longest is no more than seven and a half minutes. For an eclipse, after the eclipse, the appearance of the moon continues to move eastward for the sun.

5. Last contact. About an hour after the birth of light, when the western edge of the moon "touches" the eastern edge of the sun, it is called the last contact. Since then, the moon has completely "left" the sun, and the eclipse is over. Total solar eclipse and annular solar eclipse have the above five processes, while partial solar eclipse has only three processes: initial loss, extreme eclipse and last contact, without food and light.

The formation of the solar eclipse:

Eclipses always occur on the first day of the lunar calendar, that is, the first day of the lunar calendar, but not every first day of the lunar calendar will have an eclipse. This is because the orbit of the sun * * * ecliptic * * * and the orbit of the moon * * * form an angle of 5 9', and when an eclipse occurs, the sun and the moon must be at the "intersection of yellow and white" or descending node * * *. The moon itself does not shine, and under the irradiation of the sun, a shadow will inevitably appear on the side facing away from the sun. A solar eclipse occurs when the moon moves between the sun and the earth, which are exactly or close to the same straight line. If the shadow of the moon is reflected to the earth's surface, then the area covered by the shadow can see the total solar eclipse, and the area projected by the umbra of the moon can see the total solar eclipse.

There are five stages in the occurrence of total solar eclipse: initial loss, eclipse, eclipse, illumination and last contact. The first loss was the beginning of the solar eclipse, and it also entered the stage of partial eclipse. When the two circular surfaces of the moon and the sun are inscribed, it is a very heavy food, and the stage of total solar eclipse begins. When the centers of the circular surfaces of the moon and the sun are closest to each other, it is food, and when the two circular surfaces of the moon and the sun are tangent again, it is light. At this time, the total solar eclipse phase is over. When the two circular surfaces are inscribed, it is called the last contact, and the solar eclipse is over.

Golden ring solar eclipse phenomenon;

On the morning of 2012,21day, Tianyu will stage a rare astronomical phenomenon of "golden eclipse". The only partial solar eclipse that Beijing can see is the first loss, the worst food and the last contact. The specific time points are 2 1: 35, 6: 33: 13, 7: 4 1: 48.

The annular eclipse belt passes through the southeast of Chinese mainland. At 6: 06 in the morning, the annular eclipse was first seen in Guangxi Zhuang Autonomous Region, and then the southernmost Guangdong, Jiangxi, Fujian, northern Taiwan Province Province, Zhejiang and other places entered the East China Sea. The longest annular eclipse in China is 4 minutes and 33 seconds. When the annular eclipse occurs, that is, the eclipse stage, the moon at this time is like a "black hole" in the center of the sun, leaving only a "ring of fire" outside.

The uniqueness of this annular eclipse is that all the places where you can see it in China are at dawn, and the sun comes out with food.

This annular eclipse is another visible annular eclipse in China after1October 20th 1015. Astronomical experts say that although the annular eclipse is not as spectacular as the total solar eclipse, it is still worth looking forward to. It is understood that the next large-scale observable solar eclipse in China will wait until 20 16 years.

Preparation for photography:

For photography lovers, shooting a solar eclipse is an exciting topic. Before shooting, it is enough to have a digital SLR camera and a lens with a telephoto end of about 200-300 mm It doesn't matter whether you focus or zoom. Need to be reminded that it is best not to use the Liveview function to shoot and view the sun without covering the sun filter. Strong light will destroy your camera in an instant. Of course, don't take pictures with the naked eye without covering the sun filter. There is no doubt that you will pay the retina as the price of such foolish behavior.

The simplest method of celestial photography is to shoot directly with a camera. Many cameras can capture large images of the sun at the telephoto end. Because the position of the sun will be very different at the beginning and end of the eclipse, it is necessary to ensure that the sun is on the left side of the picture at the beginning of the eclipse and on the right side of the picture at the end of the eclipse, so that the whole eclipse can be on the picture. ?
