My colleague asked me to help, when will I see a meteor shower in the last time? Thank you

Frankly, there are no meteor showers left to observe this year. The territoriality of meteor showers is very small, and a meteor shower can be observed throughout the Northern Hemisphere and half of the Southern Hemisphere. And the observation conditions are almost exactly the same throughout China.

The Draconid meteor shower on October 8 has only 2 flows this year, and even the theoretical hope is slim.

In late October, the Orionid meteor shower is the only small meteor shower, and it is fortunate that you can usually see double-digit meteors, and the maximum radiant on the 21st is too close to the moon, and it will end at the end of October.

November 7 is the maximum of the Leonid meteor shower, but it is far from the meteor shower in 2001, maybe only a dozen.

November 8 is the Taurid meteor shower, and you can usually see four or five meteors per hour, which is not large, but the cycle is relatively stable.

December 14 is a big Geminid meteor shower, but it coincides with the Full Moon and is not worth watching.

If you must see it, it is recommended to pay attention to the Elephantids around January 4 next year.

By the way, meteor showers are observed with the naked eye, and telescopes do not achieve the observation effect.

Please refer to the following for notes on meteor showers: (it is best to read all the answers).

Draconids. This meteor shower occurs in early October, and the best time to observe it is on October 8-10, and the best time to observe it is a few hours before dawn, when the sky is clean and there is no light damage.

Meteor showers can theoretically be enjoyed anywhere, but choosing a good viewing location will increase the chances of spotting meteors. The days before the peak are usually better than the days after. Check the weather forecast in advance and plan the date and location of your trip to avoid bad weather.

In order to reduce light pollution, it is necessary to go to the countryside or nearby parks. If your options are limited, turn your back to the street lights and give your eyes at least 15 minutes to adjust to the darkness so you can catch more of the fainter meteors, and remember not to look at your phone while you wait!

Meteors can appear anywhere in the sky, so the more sky you can see, the better. Find a place where you can see the horizon clearly, away from trees and buildings. Binoculars and telescopes are not necessary because they limit the size of the sky you can see.

The Perseid meteor shower is one of the brightest and most active meteor showers of the year. Although the Geminid meteor shower also has a high time rate. However, it occurs in the northern hemisphere during the cold months of December. In contrast, the Perseid meteor shower during the summer vacation is more suitable for family and friends**.

In addition, during the Perseid meteor shower, there is also a good chance of seeing fire meteors (extremely bright), as well as meteors with long trajectories.

Generally, it cannot be seen, and special treatment is given in special circumstances.

A meteor shower (a flow of meteor showers per hour) is a special celestial phenomenon in which a swarm of meteors appears to burst out of a point in the sky and fall down. The root cause of the formation of meteor showers is the fragmentation of comets. Comets are mostly made up of ice and dust.

As the comet moves closer to the Sun, the ice vaporizes, causing dust particles to be ejected out of the parent body and into the comet's orbit like fountain water.

However, large particles remain around the parent comet to form dust comets; The small particles are blown away by the radiation pressure of the sun, forming a comet tail. The remaining material continues to remain in the vicinity of the comet's orbit. However, even small eruption velocities can cause very different periods of particle rotation.

Thus, on the next comet return, the small particles will lag behind the parent body, while the large particles will be ahead of the parent body. As the Earth passes through the dust tail orbit, there is a chance to see a meteor shower. Meteor shower activity is a comet cycle.

Requirements:

1. There are shooting stars;

2. Low surrounding brightness;

3. There is nothing to obstruct the line of sight;

So, the sky before the rain is darker, and there are clouds blocking the view, so it is unlikely to be seen.

The chance of being after a rain is a little greater than before the rain, as the air is washed away by the rain and visibility is improved. Of course, the necessary conditions must be met.

Meteors generally occur at an altitude of 80,120 km above the ground, not at low altitudes.

Weather phenomena such as rain and snow are generally in the troposphere below 10 kilometers from the Earth. If it rains, you won't be able to see a meteor on the ground.

Of course, if the meteoroid is relatively massive and does not burn up at high altitude, it will still be possible to see it until it reaches a low altitude near the ground and emerges from the clouds.

Meteors are not visible on rainy days because there are more clouds on rainy days, which makes the visibility of meteors less.

For a specific meteor shower, only when the radiant of the meteor shower rises above the horizon can you start to observe, the radiant of the Leonid meteor shower is located near the lion's head, and it rises to a more suitable position at about 2 o'clock to 3 o'clock in the morning, and the meteor shower should choose an environment with a wide field of vision, pure atmosphere, sparse population, and dim lighting, which is not suitable in large cities. Visual observation of meteors is the best method, no need for a telescope, not even binoculars, visual inspection is the best.

In addition to warm clothing, observers should also bring a record sheet, a star map for observation, a pen, a flashlight, and a timer. If you see a meteor, make a number, and record it.

Most meteoroids are depleted before they fall to the ground, and a small number fall to the ground, called meteorites. Most visible meteoroids are about the size of a grain of sand and weigh less than 1 gram. Meteoroids enter the atmosphere at speeds between 11 km s and 72 km s, and the color of each meteor varies depending on how hot it is.

There is a shelter in the middle of the sky and the clouds cannot penetrate.

If you can see the sun during the day when it's raining and it's cloudy, then I'll just say it, that's common sense.

Unless it's sunny and rainy, it's ......Hehe......No way.
