Where can I observe the Ursid meteor shower on December 23, 2011?

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 Ursid meteor shower will appear, but it may not be observed during the day.

Wishing for meteors has always been people's best expectation. On December 22, the last meteor shower of 2020, the Ursid meteor shower, will usher in a new 2021. Let's take a look at the best time and place to see the Ursid meteor shower.

The last meteor shower was the 2020 Ursid meteor shower, which was active from December 17 to 26 and reached its maximum on December 22. Nearly 10 meteors can be observed per hour. Residents of the northern hemisphere were able to see.

20 degrees north latitude (Nanning, Guangzhou, Haikou): observable all night, best in the morning.

30 degrees north latitude (Lhasa, Chengdu, Chongqing, Hangzhou, Nanjing, Shanghai): Observable all night, best in the morning.

The parent comet of the Ursids is 8p Tuttle, which is generally active from December 17 to 26 each year. Named after the meteor shower's radiant proximity to the star of the constellation Ursa Minor, the Ursid meteor shower was discovered by William F. Denning in the mid-20th century.

As a meteor group with the highest declination of the radiant, the Ursid meteor shower is very suitable for observation in the middle and high latitudes of the Northern Hemisphere, although the flow is not large, with 10 to 50 meteors per hour.

The active period of the Ursid meteor shower is from December 17 to 26 every year, with the maximum occurring on December 22 at 5 p.m. Beijing time, and the ZHR (zenith hourly occurrence rate) is about 10. The Ursid meteor shower occasionally erupts, reaching around 50 at the time of the eruption. In the last 70 years, there have not been many recorded observations of the Ursid meteor shower, including two outbreaks in 1945 and 1986.

Between 2006 and 2008, a small increase in traffic was reported. Since the radiant declination of the Ursid meteor shower reaches 76°, for lovers of our country, almost all meteors in the group of the Ursid meteor shower will not be missed, and they can be observed all night. However, compared to this month's Geminid meteor shower, the flow of the Ursid meteor shower is really low, and in the cold winter, non-"iron fans" are not recommended**.

Yesterday on the 14th, a meteor shower fell in the north, an hourly encyclopedia.

If you can see the North Star, you can.
