It is said that there will be a meteor shower this year, when is it?

After reading this question, I know that the landlord is a big novice, and he must not have seen the meteor shower, and he doesn't know how to find information about the meteor shower.

Every year, there are three major meteor showers, as well as 6-7 second-rate meteor showers worth paying attention to, and there are also writes that the flow of meteor showers varies very much from year to year, such as lions and dragons. This aspect has already been there, and the landlord may wish to take a look if he is interested.

In addition, the regionality of meteor showers is very small, as long as the owner has heard the name of the meteor shower, it can be observed throughout China.

For some meteor showers with very sharp peaks, such as Tianlong, which had a small outbreak on October 8 this year, the flow reached 100 from 1 to 5 a.m. Beijing time, but the flow at 22 o'clock I observed was less than 20. The best spot for these meteor showers, which have very sharp flows, is Europe (this area is big enough, right?). It's also a face).

For meteor showers with gentle peaks, such as Orion and Gemini, the best observation point is a ring; The former is between the Tropic of Cancer and the Tropic of Cancer, and the latter is between the equator and 50° north latitude.

With such a large range, there is no comparation in the fact that it is best to observe a certain place, as long as the height of the radiant exceeds 30°, the influence of the radiant has become a secondary factor. A nearby light has a much greater impact on the observation than running 2,000 kilometers.

Finally, tell the landlord the most authoritative way to inquire about meteor showers. International Meteor Organization**, but all in English.

If you are too lazy to read English, don't come to the astronomical page to ask questions when you hear that there is a meteor shower activity. In short, don't believe the comments on the Internet, meteor showers often erupt. Only people who have never seen a meteor shower would give such an irresponsible forecast.

The second meteor shower of the year, the Lyrid meteor shower, will occur on April 22.

2. A meteor shower is a special celestial phenomenon in which a group of meteors appears to burst out from a point in the night sky and fall down. This point, or a small area of the sky, is called the radiant of the meteor shower. To distinguish meteor showers from different directions, meteor showers are usually named after the constellation of the celestial region where the shower's radiant is located.

For example, the meteor shower radiant that appears around November 17 every year is in the constellation Leo, and it is named the Leonid meteor shower. Other popular rains include the Aquariid meteor shower, the Orionid meteor shower, and the Perseid meteor shower.

3. Some meteors appear alone, are random in direction and time, and there is no radiant point at all, and this kind of meteor is called an occasional meteor. Meteor showers are fundamentally different from occasional meteors, and one of the important features of meteor showers is that the reverse extension lines of all meteors intersect at the radiant point.

4. Meteor showers vary greatly in size. Sometimes only a few meteors appear in an hour, but they all appear to "flow" from the same radiant and therefore fall under the category of meteor showers; Sometimes, in a short period of time, thousands of meteors can burst out in the same radiant, as spectacular as the fireworks set off at festivals. When the number of meteors per hour exceeds 1,000, it is called a "meteor storm".
