What is the best way to observe the Orionid meteor shower, and does moonlight affect the observation

Tomorrow, October 21, at 1 p.m. is the maximum period of the Orionid meteor shower, which can be seen for several days before and after, and the best place to observe it is undoubtedly a place with a wide field of view, away from light sources, and not obstructed by mountains or buildings. It was the fifth day of the lunar calendar, and the moon would set very early in the first half of the night, so the moonlight would hardly interfere with our observation of meteor showers.

The Orionid meteor shower is one of the seven major meteor showers in the world, and its parent comet is the well-known Halley's Comet.

**The meteor shower radiant will rise at 4 o'clock on the 22nd, and if you are in a large city with a lot of people and more prosperous, you can see 2 per hour, and ideally you can see 20 per hour in places with less light pollution, such as the countryside. The traffic is not very large, it is considered medium. On October 23, the moon will be in conjunction with the moon, and the moon will be near Saturn and Jupiter, and the moon phase will be close to the upper wind, so you can locate Saturn and Jupiter according to the moon.

A few years ago, I saw the conjunction of Venus on the university campus, which is called the "Fairy Tale of the Stars and the Moon" (it is said that it also appeared on the 14th of this month), and the moon conjunct Venus in the shape of a crescent moon, and the bright stars of the constellation Leo are surrounded by it, which is very ornamental. The sky was beautiful, from top to bottom from orange to deep blue, as peaceful as an oil painting. When you see beautiful celestial phenomena, you can always enter a romantic reverie, and you can temporarily escape from the hustle and bustle and immerse yourself in nature, so I personally like celestial wonders such as meteor showers, and I still want to see them when I have the time.

Meteor showers are not only soothing to the soul, but also a kind of sustenance of a beautiful vision.

It is recommended to go to the top of the mountain to see, this is good, the observation is also the most accurate, the moonlight will not affect the observation effect, but the clouds will do, I hope everyone can watch this meteor shower.

Moonlight does not affect meteor shower observations. The selection of the observation site is more important, we can choose to observe in a place with little light pollution and a wide field of vision.

When observing, we should go to a place with a relatively open field of vision, away from the light source, without the obstruction of tall buildings, so that the best effect of observing meteor showers, because the moonlight will fall very early in the first half of the night, so the moonlight will not interfere with our observation of meteor showers.

The brighter the moonlight, the more it will obscure the light of the meteor, and the masked meteor will be invisible.

The Orionid meteor shower will be big tonight, and then everyone can watch the meteor shower. Meteor showers can be seen around 10 p.m. This meteor shower is relatively stable, but may need to be in a place with less light pollution.

Astronomical forecasts show that the main peak flow of this year's Orionid meteor shower will occur on October 21, and the hourly flow is expected to be around 20.

The Orionid meteor shower is active from October 2 to November 7, with its peak on October 21. The parent comet of the meteor shower is the famous Halley's Comet. Its radiant is located between Orion, Gemini and Taurus, near the celestial equator.

As a result, observers in most parts of the world can enjoy this meteor feast.

Studies have shown that there tend to be sub-peaks in the Orionid meteor shower, which can sometimes lead to a number of meteors similar to the maximum period in the nights before and after the main peak. In addition to the 21st, interested members of the public can also observe on the evenings of the 22nd and 23rd. If you're lucky, you might get a lot of windfalls.

The Orionid meteor shower has a maximum hourly zenith flow of about 20 in an ideal state, but from 2006 to 2009 it reached an hourly zenith flow of 40 to 70. The Orionid meteor shower has been reported to have the following characteristics:

1.There are many bright meteors, and they are white;

2.The flow rate is relatively stable and usually remains at a certain level;

3.The velocity of the meteor can reach 66km s, which is a fast meteor with a long trajectory.

4.Meteor showers are extremely gentle, with peak flows lasting longer and can last for a day or more.

Guangzhou residents can observe the Orionid meteor shower from the maximum sunset to 60 minutes before sunrise the next day. On October 21, the moon set at 21:58 in Guangzhou, and the next day at 6:58

27 rises. Therefore, the best observation time in Guangzhou is from 21:58 on October 21 to 5:27 the next day.

Best time to observe: after 10:00 p.m. on October 21. At 1:30 a.m., the radiant of the Orionid meteor shower rises from the northeast. At this time, the moon has set, and the moonlight will not affect the meteor observation.

The best place to observe jujubes: It can be observed in places with less light pollution and a wide field of vision, such as suburbs and rural areas. Of course, if the conditions are good enough, you can also see it on the roof of your house.

October is not only the best time to enjoy the red maples, but it is also a great time for stargazing. Late October is the best time to observe the Orionid meteor shower in 2021. So when is the Orionid meteor shower to be seen? Let's take a look at the latest property viewing strategies.

The "gift" of the Halley's Comet Orionid meteor shower will be at its maximum on October 21. At its maximum, the ZHR (the number of meteors that can be seen per hour when the radiant is directly above the head under ideal viewing conditions) is about 20.

Astronomical forecasts show that the great moment of this year's Orionid meteor shower will occur around 20 o'clock on October 21. There is no expectation of an outbreak, and the big peak is relatively mild. About 20 meteors streak across the eastern night sky every hour.

The characteristics of the Orionid meteor shower are very obvious: meteors are fast, bright and white, and the peak lasts for a long time.

Best observation location: Observation can be carried out in places with less light pollution and a wide field of vision, such as suburbs and rural areas. Of course, if the conditions are good enough, you can also see it on the roof of your house.

Around 8 p.m. on October 21.

On October 21, the Orionid meteor shower peaks. It is estimated that there will be about 20 meteors per hour.

Introduction to the Orionid meteor shower:

As the first periodic comet confirmed by humans, Halley's Comet gave birth to the Urtaid Aquariids meteor shower in the first half of the year and the Orionid meteor shower in the second half of the year. The characteristics of the Orionid meteor shower are very distinct. Meteors are extremely fast, have long trajectories, and there are many bright meteors.

Meteor shower features:

The Orionid meteor shower is characterized by its extremely fast speed and long trajectory. If you see such a meteor with its trajectory pointing in the opposite direction of the constellation Orionids, you can conclude that it belongs to the Orionid meteor shower.

On October 21, any morning near the summit, astronomical observers can begin searching for the lower constellation Orion in the eastern sky before dawn. Orion can be seen in the mid-northern latitudes. Although the radiant or origin point of meteors is in the constellation Orion, meteors can also appear far away from the constellations.

Like most nocturnal observations, light pollution can prevent you from observing the Orionids. You should stay as far away from the city lights as possible. You can go out at about half past one in the morning, and it takes about 20 minutes for your eyes to adjust to the dark environment.

It's best to dress warmly so you don't catch a cold. Lie down and look at the sky with only your eyes. Binoculars and astronomical telescopes do not improve observation because they are designed to observe more stationary objects in the sky.

Because some Orionids can fly at relative speeds of up to 148,000 mph (238,000 kmh), some Orionids appear quickly and brightly. "That's just 6 kilometers an hour slower than the fastest meteor shower of the year, the Leonids," Cook said. ”

Anyway, this year is either a blue moon or a red moon, and now there are meteor showers, do you want to see it? However, everyone must want to know about the meteor shower to watch it, and everyone who wants to see the best time to watch it definitely doesn't want to miss it, so let's go and see it now.

Peak period: around October 21, 2018.

This year's Orionid meteor shower is most likely to occur around the 21st, with no obvious outbreak expected, and the maximum peak is a relatively gentle Kai-shaped macro, with about 20 meteors passing by every hour. The best time to observe in China is from the early morning of October 21 to before dawn.

Although you may have missed the best time to observe the Orionids, the Orionid meteor shower denies that the active period lasts almost throughout October and early November, so you can see if there is a chance to see it again during this time. The first ** Orionid meteor shower was in 2014, and then there were in 2015, and finally this year, whether it can be seen in the future, or in ** is still a question, although the Orionid meteor shower is every year.

The characteristics of the Orionid meteor shower are very distinct. Meteors are very fast, and there are many bright meteors. And most of them are white, and the peak flow lasts for a long time, which makes the Orionid meteor shower very suitable for public observation.

The flow of the Orionid meteor shower is relatively stable, and the maximum number of Zenith meteors per hour is usually around 25.

It's best to choose a place that is open and not sheltered by mountains or buildings**. This way, you can see the meteor more clearly. So everyone should choose a suitable place in their own city, such as grandma in Guangzhou.

6. Tianlu Lake and Nankun Mountain are very suitable for meteors. When observing meteors, you can use the naked eye directly, and you don't need a telescope. Because the observation of meteor showers requires a large field of view, the field of view of the human eye is more than 100 degrees, while the ordinary telescope only has a few degrees, so it may not be visible with a telescope.

Since you don't need equipment, you have to work the venue and the weather. During the meteor shower, the weather is bad and you can't see it, and the night with high transparency, clear and moonless is the best time to watch. When observing, pay attention to cold and warmth, and also pay attention to insect prevention, because there are more meteors in the second half of the night than in the first half of the night, so most of the time is generally observed overnight.

The weather in Wuhan this year is not very good, it has been raining for the past few days, it is very likely that it will not be visible, but there should be a lot of friends in other places who have seen it, this year you can wait a little longer, maybe you can see it, or you can also choose to be in next year**, it is also a very good choice. Maybe this year it's one person watching the meteor shower, and next year it's two people together.

Everyone must pay attention to keeping warm when going to watch the meteor shower, the weather is not very good recently, many places have cooled down, and some places have snowed, so you must remember to keep warm when you go out, this time the meteor shower is on the weekend, there must be a lot of friends to see it.

Although it is said to be a meteor shower, the landlord should not think that the meteor shower looks like it is raining as the TV says, this is called a meteor shower, which is very rare. The most recent meteor shower was the 2001 Leonid meteor shower.

Orionid meteor shower, the active period is in October and early November, the peak is on October 21, the radiant Orion rises from the east at about 22 o'clock in the second half of the month, about 25 per hour, this meteor shower is not affected by the moonlight, it is also rare, although the number of meteors is relatively small, but if the weather is good, this meteor shower is still worth seeing.

**A few things to keep in mind when it comes to meteor showers:

1.Find the radiant of the meteor shower, don't look at the sky aimlessly, for example, the Quadrantid meteor shower a few days ago, the radiant rises at about 1 o'clock in the eastern sky, so we need to look in the direction of the eastern sky: the best time to observe is in the second half of the night.

2.To find a place with less light pollution and the best air, the light source is a big obstacle to seeing the meteor shower, so the place you find should have at least about 100 stars to see, so that the effect will be better.

3.Dark adaptation, when looking at the starry sky from a place of light to a dark place, it takes about a minute to get your eyes used to the darkness.

4.When watching meteor showers, you need to use star charts, flashlights and other tools to find the radiant points, and remember to cover a layer of red cloth when looking at the star map with a flashlight, so that it will not be too dazzling and affect**.

5.Remember to see with the naked eye, it is not suitable to use a telescope to see meteor showers, because the field of view of the telescope is too small, the field of view seen by the naked eye is relatively large, the number of sights is more, and the opportunity is relatively large, from the perspective of the earth, there will be more meteors in the second half of the night, which is also very related to the brightness of the sky and the surrounding environment, because many people have fallen asleep in the second half of the night, the light pollution is naturally smaller, and the brightness of the sky is darker, which is more conducive to watching meteors.

6.**In winter, you should pay attention to keeping warm in meteor showers, you can get a blanket on the ground to cushion it, pay attention to keeping warm.

7.Record the number of fire meteors and bright meteors you see, and count how many meteors you see.

Enjoy watching.

Hope it helps you, I hope it helps.
