What do I need to pay attention to when observing meteor showers at night?

Remember to wear a hard hat and beware of being hit on the head by the pop!

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.

I can't see it tonight, so I'll give you the schedule for the future.

2018 meteor shower time.

January Quadrantid meteor shower, 3-4.

April Lyrids, 21-22.

Etaaquarids in May, 21-22.

The Lyrids meteor shower in June, 14-16.

Delta Aquariids in July, 28-29.

Capricornids in July-August, 29-30.

Perseids in August, 12-13.

The draconids are expected to appear on the 12th-13th in October.

The Orionids meteor shower is expected to appear from October to November on the 21st to the 22nd.

The Leonids meteor shower in November is expected to appear on the 17th-18th.

The Geminids meteor shower (Geminids) in December is expected to appear on the 13th-14th.

The Ursid meteor shower is expected to appear in December from the 17th to the 26th.

Meteor showers are usually more likely to occur between 2:15 a.m. and 4:45 a.m.

A meteor shower is an astronomical phenomenon in which many meteors are emitted from a so-called radiant in the sky in the night sky. These meteors are fragments of the universe known as meteoroids that are projected into the Earth's atmosphere at extremely high speeds as they orbit in parallel orbits.

Features of meteor showers:

Most meteoroids are smaller than gravel, so almost all meteoroids are destroyed in the atmosphere and do not hit the Earth's surface; Debris that is capable of hitting the Earth's surface is called a meteorite.

Meteor showers that are particularly large or unusual in number are known as "meteor outbursts" or "meteor storms" and can produce more than 1,000 meteors per hour. Before sunrise on October 21-22, 2018, the Orionid meteor shower will reach its maximum.

Analysis: The parent comet of the Draconids is called "21p", which is permanent and distinguishes it from any other comet. where 21 is the number and p is the periodic comet.

Comet 21p was only discovered by astronomers in 1900, and its orbital period is years. The most recent perihelion dates for its orbit to the Sun were June 1972, February 1979, September 1985, April 1992 and November 1998, and the next perihelion is expected to be in early July 2005. According to the operation law of meteor swarms, whenever its parent comet passes around the perihelion date, its meteor shower is full; When its parent comet is far from the Sun, its meteor shower becomes thin.

The last time Comet 21p passed perihelion was in November 1998, and on the evening of October 8 of the same year, astronomy enthusiasts in China and Japan invariably observed the explosion of the Draconid meteor shower, with as many as 700 meteor showers per hour.

The Draconid meteor shower is called the Draconid meteor shower because its radiant is located in the constellation Draconia. The specific radiant point is located at 262 degrees right ascension and 55 degrees declination. The Leonid meteor shower, which is more familiar, has a meteor velocity of 71 kilometers per second, while the Draconid meteor shower, whose meteor speed is only 20 kilometers per second, is "slow".

Observing the Draconids, high latitudes (north) are more favorable than low latitudes (south). The best time to observe the Leonids and Perseids is in the early hours of the morning, while the best time to observe the Draconids is at night.

When is the best time to observe? The best time to observe Li is on October 8 and 9, and the best time to observe is between 40 minutes after sunset and 12 o'clock at night. Observe the northerly evening sky.

On October 8, the sunset time in Guangzhou was 18:08. The observation site should be selected on a clear night with a wide field of vision, sparse population, dim lighting and brilliant stars. Observing meteor showers in big cities can be "grainless".

Summary. Hello dear, happy to answer your questions. Can you still see a meteor shower on a rainy night, the answer is that you can't see a meteor shower on a rainy night.

Because the sky is mostly cloudy on a rainy night, it is invisible with the shade of clouds, but it is okay if the clouds dissipate quickly. Many times it is not visible, and special cases are treated specially.

Hello dear, happy to answer your questions. Can you still see a meteor shower on a rainy night, the answer is that you can't see a meteor shower on a sleepy night after the rain. Because the sky is mostly cloudy on a rainy night, it is invisible with the shade of clouds, but it is okay if the clouds dissipate quickly.

Many times it is not possible to see, and the special treatment of the special locust crack is different.

Can you elaborate on that a little bit more?

Many times you can't see the meteor shower pro, special treatment in special cases. A meteor shower (a meteor shower with a flow of one meteor per hour) is a special celestial phenomenon in which a group of meteors appears to burst out from a point in the sky and falls. 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 sun's radiation pressure, forming a comet trapped 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 trail of the dust tail, there is a chance to see a meteor shower. Meteor shower activity is a comet cycle.
