When was there a meteor shower in 2012? At what number? What s the seat?

At around 10 a.m. on December 23, the Ursid meteor shower will appear, but it may not be visible during the day, but it will continue for a while, and you should be able to see it at night. According to the situation of previous years, the Ursa Minoris meteor shower has 10 meteors per hour, although it is not as spectacular as Gemini, but because it is November 29 of the lunar calendar, it will not be affected by the moon, the sky is relatively dark, and it can be observed by the naked eye.

However, meteor observation requires a lot of air and darkness, so if you can't count more than 200 stars at the location you are observing, it is recommended that you sleep.

There are a few things to note about meteor showers:

First of all, meteor showers are not like rain as expected, as long as the meteors come out of a radiant, they can be considered meteor showers. There are nearly 40 meteor showers that can be called meteor showers every year, and you only have to think about how many meteors you can see every year. The flow of meteor showers in the forecast refers to the number of meteors that can be seen at the zenith of an hour by a person with normal vision in the absence of lights, moonlight, clear weather, and no wind when the meteor shower is at its peak.

It's hard to get to this point, so the number of meteors you can actually see is much lower. The larger meteor showers each year include the Quadrant meteor shower around January 4, the Lyrid Lyrid meteor shower around April 22, the Perseid meteor shower on August 13-14, the Leonid meteor shower on November 17-18, and the Geminid meteor shower around December 14.

Second, it is difficult to predict meteor showers to the hour, because the mass of matter that forms meteor showers is very small, and the slightest gravitational disturbance will change the time to reach the Earth.

Again, you must not use a telescope for meteor showers, you can use the naked eye, and the use of telescopes will seriously affect the effect because of the small field of view received.

Finally, my advice is that if you're not a hobby of astronomy and just want to see meteor showers, don't look no further. In fact, this is largely the result of the fact that the reporter does not understand astronomy and hype. They thought the meteor showers were the same as the one in 2001.

But if you want to observe, you have to go to the field or the suburbs, otherwise the city lights will make you see nothing.

The first meteor shower of 2012 was the Quadrantids, which reached their peak around January 4 each year.

At the same time, it is also one of the four relatively stable meteor showers every year, and it can be seen almost every year.

There is a quadrant, around January 1st to 5th.

The address above, if you can, take a look.

May meteor shower name: ETA Aquarids Comet Parent body: 1C Hally

Radiant point: Aquarius ETA Estimated date of appearance: 5th-6th.

Description: The density of meteors is high, but the flow is not very stable (the lowest is only a dozen, the highest can be hundreds per hour). The equator and the southern hemisphere can be observed in the hours before dawn, and the north is not conducive to observation.

Many intra-swarm meteors leave long orbital trails in the sky.

Let's take a look at this first

December is destined to be a romantic month. In addition to the total lunar eclipse, on the 14th of this month, the starry sky will also be romantic, and the Geminids, Ursid meteor showers, and Mercury's western elongation are also worth looking forward to.

This year's Geminid meteor shower will be at its most high, from 9 a.m. to early morning on December 14. The Geminid meteor shower's radiant is located near North River 2 and rises almost shortly after sunset, so we can observe meteors in its group throughout the night. If the weather is clear and people face northeast and stand in the open area, they will see a romantic sight of 100 to 120 meteors per hour streaking across the night sky, so it is the most observable meteor shower of the year.

This year's Ursid meteor shower is expected to be at its maximum at around 10 a.m. on December 23, which will also be visible through the night. The number of meteors per hour does not exceed 10, but it is slower and comes in a variety of colors.

Moreover, around the 22nd, it is already a waning moon, and the moonlight has little effect on the observations. For observers in most parts of China, the radiant of the Ursid meteor shower will be visible all night, and the best time to observe it is from the evening of the 22nd to the dawn of the 23rd.

Before dawn on the 23rd, low in the southeast, Mercury's western elongation will appear, which is the best time to observe Mercury. Mercury's greatest western elongation is when Mercury appears in the west of the Sun and its angular distance reaches its maximum. You must know that Mercury is so close to the Sun that it is usually lost in the sun's brilliance, making it the most difficult planet in the solar system to observe.

The top three hyped meteor showers are the following:

Draconids: October 8 is at its peak, and there is a small eruption this year, and the flow can reach 200, but the radiant has already fallen at 1 o'clock, so China cannot see the peak.

Southern Taurid meteor shower: To be honest, I don't know when this meteor shower is at its peak, because it has a small flow of single digits, but it can stay at a similar flow for almost two months. It is characterized by the occasional fire meteor, and the brightest meteor I have ever seen is due to him (-10 magnitude, the brightness of the moon).

Orionid meteor shower: October 21 is at its peak, a very modest meteor shower, with a flow of 30, and the peak can be maintained for more than 48 hours, so it is almost the same a day earlier or a day later.

But I personally suggest that if the building is mainly observed, the latter two are directly excluded.

The northern and southern Taurids (there are two, almost) are rarely observed, and they are observed in passing while observing other meteor showers. It's not that the Orionid meteor shower can't be seen, but hitting the big moon this year makes it meaningless for people who watch the excitement.

The Draconid meteor shower can still be considered for observation, but to be honest, the conditions are really not good, the same, hitting the moon, but because of its large flow, maybe it can "get out of the mud without staining", right? Find a place where you can see 200 stars (there will not be too many stars in the sky with the moon), observe the first half of the night, the mathematical expectation is about 30 (I am not very responsible to estimate the flow of about 100), I don't know if this number is satisfied with the landlord? What about the Perseid meteor shower on the 13th Beijing time?

Let's be honest, this year is a small year for meteor showers, and all the slightly larger meteor showers hit the moon. Is it related to the moon? Probably, there will be a very good total lunar eclipse on December 10.

The landlord's understanding of meteor showers is relatively general, and I personally suggest that you don't look at meteors with the moon on your head, and you can't draw them.

Yes, it started around 9 p.m. on the 14th and ended in the early morning of the 15th, but it may not be visible due to urban light pollution and moonlight.

In fact, it was from the night of the 14th to the early morning of the 15th!

The Geminid meteor shower occurs around December 13-14 each year, and the maximum flow can reach 120 birds per hour, and the flow is very large and lasts for a long time. The Geminid meteor shower originated from the asteroid 1983 TB, which was discovered in 1983 by the IRAS moon and which scientists judged to be the remains of a comet that "burned out". The Geminid meteor shower radiant is located in the constellation Gemini and is a famous meteor shower.

Who has a ** to shoot it down, every time.

Not necessarily, there is a small chance of a meteor shower for two days in a row.
