Total solar eclipse What to prepare for in 2009

First see if you are in the **, whether you are in the whole food zone. If you don't want to think about it, go ****. ** Prepare a filter (there are ** glasses sold by the observatory, of course.

If you don't use anything dark and transparent, you can do it. For example, the traditional film black title, the floppy disk that was commonly used in the past can be removed from the disc inside). A few days in the morning, look at a place near your home where you can see the sun from 8-11 a.m.

Don't start the eclipse only to find that the sun is about to be obscured by the tall buildings opposite.

What the hell? Where can I see it?

If you have any, prepare sunglasses, and if you want to take pictures, prepare filters.

An eclipse is an astronomical phenomenon in which the sun is completely obscured by the moon in parts of the earth. Total solar eclipses are divided into five stages: initial loss, eclipse, eclipse, regeneration, and recovery. Since the Moon is smaller than the Earth, only people in the moon's umbra will be able to see a total solar eclipse.

Folks call this phenomenon the Tengu Eclipse Day.

On December 1, 2020, astronomical experts introduced that a total solar eclipse will appear on December 14 and occur in the Southern Hemisphere.

On December 4, 2021, Beijing time, the only total solar eclipse of 2021 was ushered in. This total solar eclipse starts at 13:29 and ends at 17:37 Beijing time on December 4, and cannot be seen in China. The total eclipse zone begins in the southern Atlantic, passes through Antarctica, and ends in the southern Pacific Ocean.

Principle of Phenomenon:

A total solar eclipse occurs because the Sun is close to a point where the Moon's orbit meets the Earth's orbit, and at the same time the Moon is at the farthest point from that point. That is, the linear propagation of light.

The reason why a total solar eclipse occurs is because there is a magical symmetry. The Sun is 400 times the diameter of the Moon, and it is exactly 400 times the distance from the Earth. As a result, when the Moon is completely between the Earth and the Sun, the Sun's surface is completely obscured for those who are completely in the Moon's shadow.

The sun turned black, leaving only a golden halo, and the sky turned indigo. Birds may lose their orientation or fly back to their nests, while bats and other nocturnal animals may come out sleepy.

If you want to see a total solar eclipse in China, you will have to wait another 19 years, that is, in 2035.

On September 2, 2035, a total solar eclipse will be visible in central and southern Xinjiang, northern Gansu, central and southern Inner Mongolia, central Hebei, most of Beijing, northern Tianjin, and southern Liaoning, and partial eclipses will be visible in other parts of the country (except some islands in the South China Sea).

The total solar eclipse in 2009 will take place at 8 a.m. on July 22 (the first day of the sixth lunar month), and the total eclipse will last up to about 6 minutes.

In the middle and lower reaches of the Yangtze River in China, Chengdu, Chongqing, Wuhan, Hefei, Hangzhou, Shanghai and many other cities have seen the longest total solar eclipse of this century, with the total eclipse lasting as long as five or six minutes in many places, among which Tongling in Anhui Province has been identified as the best observation point in the world. In the process, the lunar umbra travels eastward along the Yangtze River, sweeping across both sides of the middle and lower reaches of the Yangtze River.
