How many years does the solar halo occur?

There is at least one solar eclipse in the world every year, but there are total solar eclipse, annular solar eclipse and partial solar eclipse, and some of these phenomena are rare. Even if they happen, you may not be able to see them in your area. So, how many years does the general annular eclipse occur? How many years does an annular eclipse occur? Let's get to know each other.

How many years does an annular eclipse occur? Every few years.

annular solar eclipse

Global scope: 1-2 years; Within China: once every 10 year.

annular solar eclipse

The principle of annular eclipse;

The principle of annular eclipse is similar to that of total solar eclipse. The annular eclipse also occurs because the moon is between the sun and the earth, but it is far from the earth and cannot completely cover the sun.

The process of annular eclipse is divided into initial loss, partial eclipse, initial eclipse, heavy eclipse, final eclipse, partial eclipse and last contact.

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.

Every "astronomical feast" is a good opportunity to popularize astronomical knowledge to the public. In order to let people know more about astronomy, the China Astronomical Science Network Committee, which was jointly established by many domestic astronomical institutions, once set up the China Astronomical Science Network in Dali, Yunnan. The endless universe and spectacular astronomical phenomena can stimulate people's thirst for knowledge and exploration, strengthen the capacity building of astronomical science popularization, innovate the forms of science popularization, and improve the scientific literacy of the public in China.

Observation items:

According to astronomical experts, observing the annular eclipse on the ground requires certain weather conditions. If it rains, it will definitely miss the spectacle of the annular eclipse. At present, the rising mode of "watching the sky by plane" effectively avoids the weather obstacles, but if you need to fly during this period, you can observe the annular eclipse well. If you are waiting for boarding, you can choose the airport boarding gate as the observation place. If you are on an airplane, because the airplane is flying above the clouds, it is less affected by the clouds, so it is more conducive to observation.
