The Leonid meteor shower ushered in a grand event on June 7 19.

165438+ 10 is there a wonderful "astronomical drama" in October?

Yes, 165438+ The night in October turns from cold to cold, but the canopy is still wonderful. The reporter learned from the Beijing Planetarium that there will be four celestial phenomena in turn this month, and the Leonid meteor shower, which impressed the public deeply, is expected to usher in a grand event on 17.

1,165438+1October 1 1, west distance of mercury.

On the day of "Double 1 1", Mercury will usher in the last long distance of this year, which is the long distance to the west that appeared in the eastern low sky before sunrise. Mercury's period of revolution is only 88 days. For observers on the earth, it is a great distance when it appears on the east and west sides of the sun in each cycle and reaches the maximum angular distance.

For the area of 40 north latitude, the horizon height of Mercury can reach 17 at sunrise that day. Take Beijing as an example. Mercury rises at 5: 17, so there is plenty of time to appreciate and photograph Mercury. Mercury can reach -0.6 at such a great distance.

2.165438+1October 17 Leonid meteor shower is particularly large.

Leo meteor is an occasional large-scale meteor shower, known as the "king of meteor showers". Active in late autumn, especially in mid-June 165438+ 10 every year.

According to the current forecast, the maximum value of this year will appear at 1 17+09: 00 Beijing time. The radiant point of Leonid meteor shower will not rise until around midnight, and the observation time is from midnight to dawn. For the observers in China, they can try to observe from midnight to dawn at 17 and 18. Due to the low temperature in May 438+065438+1October in late June, especially in mountainous areas far away from urban light pollution, attention should be paid to safety and warmth when observing meteor showers.

3. 165438+ 10/0/9 binary moon.

Jupiter and Saturn are the two most massive planets in the solar system, and the period of revolution is 1 1.9 years and 29.5 years respectively. On the celestial sphere, they move very slowly relative to the background stars. About every 20 years, the public will have the opportunity to appreciate the "combination of wood and soil", which is one of the highlights of the astronomical phenomena at the end of 2020. This time, the two planets "recently" appeared on June 265438+February 2 1, and their angular distance was less than 4 in the middle and late June165438+1October.

165438+1October 19 On the evening of the fifth day, the moon will come near this sky area, and the phenomenon of double stars accompanying the moon will be staged. Eyes. On that day, Jupiter was very bright, reaching -2.7, while pale yellow Saturn was much dimmer, only about 0.6.

4. 1 1.30 penumbral eclipse

From the afternoon of1October 30th to the evening of 165438+ Beijing time, there will be a penumbral eclipse that is difficult for the public to detect. If the moon never enters the umbra of the earth during the eclipse, but passes through the penumbra, the change of the brightness of the moon surface will not be obvious. In most cases, the penumbral eclipse is not as good as the brightness change of the moon caused by poor atmospheric transparency.

The penumbral eclipse begins at 15: 30 Beijing time and ends at 19: 56.

Records of Leonid Meteor Shower:

1902, Chinese astronomers recorded the Leo star shower for the first time;

1799, the famous German scientist Humboldt recorded this phenomenon in Venezuela.

1833, a rare star rain appeared in North America. It is estimated that 240,000 meteors broke through the sky in 9 hours.

1866 Comet Temple-tatar was discovered and its orbit was determined, and star showers were observed in Europe.

1899, the expected star rain did not appear, and the public's confidence in the reliability of astronomical calculation was shaken;

During the period of 1933, there was still no report of star rain.

1966, the spectacular "star rain" appeared again in the midwest of the United States. It is estimated that there are 654.38 million meteors falling from the sky every hour during the rush hour.

1998, the Leonid meteor shower visited the earth again, which made most modern people really realize this "king of meteor showers".

At midnight of 2001118, more than 30 million people all over the world were waiting for the meteor shower.

2013165438+1October 17 The radiant point of this meteor shower is located in the head of Leo, and it will not rise until midnight in mid-June165438+1October.

How big is the meteor shower of 1998?

There are about 200 meteors visible to the naked eye within 1 hour. At the same time, the Czech side also sent an email saying that the radar record of its meteor reached a great level at 17 Beijing time 12.

1998165438+1October 18 in the early morning, nearly 10,000 astronomy enthusiasts and astronomers gathered at four observation points in Xinglong, Miyun, Shahe in Changping and Niulanshan No.1 Middle School in Shunyi, waiting for the arrival of the meteor shower in the chilly wind. However, the mysterious universe played a joke on people.

The lion constellation advanced the most wonderful performance to the early morning of 17, and turned the meteor rainstorm predicted by 18 from 2 am to 4 am into scattered meteors with only 20 or 30 meteors per hour, which really disappointed the expected observers.

Although the flash of every meteor caused a burst of cheers, at 4 am, the person in charge of Xinglong Observatory had to announce that the Leonid meteor shower had arrived early in the morning of 17 due to inaccurate prediction, and reached a great height at about 3 o'clock 15.

After the meteor in the Leonid meteor shower, there will be a short cloud-like trace in the sky, which is the meteor trail. Fireballs sometimes appear in Leonid meteor showers.

In the annual astronomical observation, the Leonid meteor group is very similar to an unstable rocky comet. Meteors have been around for many years, usually averaging over 65,438+05 meteors per hour. In some special years, Leo meteor swarms can suddenly eject spectacular meteor storms, with an average of thousands of meteors per hour.

The maximum discharge of Leonid meteor shower in 20 14 years is expected to be at 0: 00 and 6: 00 on June18, Beijing time, and the maximum discharge this time is 15 per hour.

165438+ There are four astronomical dramas to watch in October. What are the specific circumstances?

There are various astronomical wonders in China almost every year, but recently it was reported that four astronomical wonders appeared in June165438+1October this year. 165438+1What are the four astronomical wonders in October? When can I watch it? Details are as follows:

According to the astronomical forecast, the astronomical phenomena that will appear in June 165438+ 10 are: the westward distance of mercury, the Leonid meteor shower, the double-star arched moon and the penumbral eclipse.

The first appearance was "Mercury Westward Distance" on June 1 65438+1October1day. According to an astronomer, "This is a good time to observe the six distances of Mercury this year. By then, if the weather is fine, the public interested in China is expected to see the rare appearance of Mercury in the morning around a long distance. "

The second is the Leonid meteor shower, which has the reputation of "the king of meteor showers". It will visit the earth on June165438+1October 17. Astronomers said, "The forecast shows that this year's meteor shower will appear around 17 19, and the interested public in China can observe it from 2 am to sunrise in 17 and 18."

In 2020, the moon will approach Jupiter and Saturn almost every month, and the third game will be staged again in June 165438+ 10/9. This time, the distance between the three will be closer and more noticeable. "At that time, the' double star arched the moon' will form a' crooked smile', which is very interesting." Astronomers say so.

"165438+1From the evening of October 25th to the morning of 26th, Mars with good observation conditions will be accompanied by a full moon, and a romantic moonlight express will be staged." Astronomers say.

165438+1On October 30th, the fourth "penumbral eclipse" will occur over the earth. According to astronomers, when the penumbral eclipse occurred, the moon looked a little "dim" than usual. "Leonid meteor shower" and "penumbral eclipse" will be staged in the sky at the end of the month, which is tantamount to a visual feast for astronomy lovers.

I only remember seeing a meteor shower in 1997 or 1998.

Leonid meteor shower at 1998.

For many astronomy enthusiasts, the Leonid meteor shower is the first teacher. The two explosions of 1998 and 200 1 made many people like astronomy and are keen on meteor shower observation. However, in recent years, the Leonid meteor shower has been silent, and the maximum zenith flow is less than 20 per hour.

The local peak of 1998 "rainstorm" occurred at 4: 30am Beijing time 165438+ 10/8, and the hourly zenith meteor flow was about 180, which was basically consistent with the forecast.

Little knowledge of meteor shower

From the earth, the meteor shower seems to emanate from a point in the night sky, which is located in a small sky area called the meteor shower radiation point. People usually name meteor showers after the constellations in the sky where their radiation points are located. According to experts, the mother comet of Leonid meteor shower is 55P comet Temple-Tuttle, with a return period of about 33 years. The last perihelion was 1998, when a meteor storm occurred.

The meteor shower in 2009 mainly came from the dust clouds thrown by comets of 1466 and 1533. When a comet approaches the sun, it will melt the ice in its dust particles, which are mostly larger than sand. For most comets close to the earth, they will burn in the atmosphere and form meteorites.

Luoyang daily-165438+ 10 "meteor shower" and "total lunar eclipse" will be staged in Tianyu.

1October 201118 When did the Leonid meteor shower appear?

Outbreak date165438+1October 18 at 2-3 am. Although there was a lot of traffic when it broke out, the Leonid meteor shower was unknown in most years, with an hourly flow of only about 20. According to the forecast given by the International Meteor Organization, this year's Leonid meteor shower is likely to appear around 1 18+08+02 Beijing time. By then, it will be daytime in China, so the observation conditions in Europe and West Africa will be better. It is unlikely that there will be a large flow in this Leonid meteor shower. Even if there is a small-scale outbreak, the duration is short. The radiant point of the Leonid meteor shower is located in the center of the "big question mark" written by Leo. The radiation point will rise at midnight in mid-June local time at 5438+065438+ 10. We can only observe the meteors in the group in the second half of the night, so the observation in the first half of the night is meaningless. But this year's big cycle coincides with the last quarter of the moon, and moonlight will have a great influence on the observation throughout the second half of the night.
