November 5, 2009, the specific time of the Southern Taurids

It's hard to calculate exactly what time tonight will be, as meteor showers occur over a roughly period of time. What you will see when you look at the night sky tonight should be the whole night. There will be more in the next few days:

The Yangtze River **November 4** This month will usher in the last big drama of this year's "International Year of Astronomy" - the Leonid meteor shower. Following last month's Draconid meteor shower and Orionids, there are two more meteor showers this month, which dazzle the eyes in the cold night sky.

November 12 Taurid meteor shower.

The Taurid meteor shower is formed by the friction of debris in the orbit of Comet Enke, and because of the different radiants, people call the northerly Taurid meteor shower "Northern Taurusid" and the southerly one "Southern Taurids". They "visit" Earth every autumn, from late September to the end of November. This year's Southern Taurids will be at their maximum on November 5; The Northern Taurids are at their maximum on November 12, when the Moon is waning and has little effect on observations.

At about 10 o'clock in the evening of the 12th, the public can choose a place away from the interference of city lights and patiently look up at the southeast sky; Since meteor showers are slow, around 27 kilometers per second, there are more bright meteors, and when they pass slowly, they are easy to catch in the night sky.

November 18 Leonid meteor shower.

Many people remember the massive explosion of the Leonid meteor shower in 1998. According to the calculations of many meteor shower experts, this year's Leonid meteor shower will bring surprises, and this year there will be an outbreak of "heavy rain" level.

From 4 p.m. to 8 a.m. the next day on November 17, it is the main time period of its activities. At 5:44 a.m. and 5:51 a.m. on the 18th, there will be two "heavy rain" level flow peaks, and the maximum number of meteors that observers can see is around 950 and 600 respectively, and may even be in the thousands.

According to experts, the night of the Leonid meteor shower is the first day of the tenth lunar month and is not affected by the moonlight. At that time, the observation time will be relatively long, and observers should pay attention to cold protection and warmth. (Hanwang-Yangtze River**-Li Jia).

Meteor showers don't have an exact time. It generally always peaks before dawn.

The Taurid meteor shower is a very long-lasting and rare meteor shower, with a number of similar meteors to ordinary meteors.

A meteor shower is not like a solar eclipse, it can be seen halfway around the world (night hemisphere). It can be seen in almost all parts of our country.

This year's forecast from the International Meteor Organization indicates that the Southern Taurids will be active from September 10 and will continue until November 20, with a high probability of occurring on October 10. At this time, the radiant of the meteor shower is still at a definite distance from the constellation Taurus, which is located in the celestial region of the constellation Pisces. Because the flow is small, the forecast maximum time of the Southern Taurids will not be too accurate.

Usually, astronomy enthusiasts don't go out of their way to observe it, but when they observe other meteor showers in the fall, they will see several intraherd meteors of the northern and southern Taurus. Since the meteoroids are only 27 kilometers per second, most meteors in this group appear to be relatively slow, and it is not difficult to distinguish them from other groups.

By the way, as one of the two meteor showers brought to us by Halley's Comet every year, the Orionid meteor shower has a relatively stable flow, with a maximum ZHR of around 25, and in recent years it has exceeded 50. Last year, even though the moonlight was heavily affected, the Orionid meteor shower still reached more than 30 visually. As such, it is also the most noteworthy meteor shower in October every year.

The Orionid meteor shower is active throughout October and early November. According to the forecast given by the International Meteor Organization, the maximum size of the meteor will occur on October 21 this year, and the exact time is uncertain. The Orionid meteor shower has a meteoroid velocity of up to 66 kilometers per second, which is a fast meteor.

The radiant of the Orionid meteor shower, located between the bright star Betelgeuse and Gemini, will rise in the east at around 10 p.m. local time in late October, and the first quarter moon will have an impact on observations starting in the early morning of October 21 this year. The Orionid meteor shower is characterized by being extremely gentle and may last for l days, or even longer. If the weather is fine, the meteor shower is still worth observing.

It was late on the 8th to the early morning of the 10th, and the direction was northwest, so it was a relatively large meteor shower, so it should be visible, but it was easy to be affected by the moonlight.

The question is the same as above, but a few specific points, urgent.

Some people say it's around 22 o'clock in the evening, and some people say it's between 23 o'clock and 24 o'clock in the evening!!

On the 21st, if the moon does not affect the observation of meteor showers, if the weather is fine, as long as you look southeast at around 23 o'clock, you can see meteors streaked across the night sky.
