How many meteor showers are estimated to be there this year

Meteors are there every day. The landlord is interested in finding a moonless sunny night to walk in the suburbs.

If the sky is full of stars and the Milky Way hangs obliquely, even if there is no major meteor shower activity, twenty or thirty meteors can be dealt with alone.

As for meteor shower activity, it depends on the amount of meteor shower. There is also cloud coverage and light pollution at the observation point.

There's a formula that says it all:

Number of meteors seen = meteor shower flow * COS (radiant height) * (1 - cloud occultity) * brightness index (limit magnitude.

In other words, the greater the flow of a meteor shower, the more meteors there are.

The higher the radiant height, the more meteors there are (anything greater than 30° has no effect).

The smaller the cloud occultation, the more meteors there are (this is easy to understand).

The lighter the pollution, the more meteors (the main influencing factor for observations in cities).

Using this formula, although it is not possible to accurately predict the number of meteors, it is possible to make a basically accurate estimate.

For example, for example, in this year's Perseus, the flow rate of the meteor shower = 80. The radiant altitude is about 60° (ignored), the weather is fine because of the influence of the full moon, the limit star, etc. (not as good as the city).

Personally, I estimate that I can see 2-3 meteors in an hour, and the observation results are roughly in line with my estimate, and I can see 7-8 meteors in 5 hours.

The moon has a post-limit magnitude of 5, and the mathematical expectation is around 15 stars per hour, and the observations are about the same, seeing 5 stars in half an hour (dawn......）

Meteor showers are substantial, not substantial.

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 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, at least to the suburbs. Because the lights in the city will interfere with the lights and you won't be able to see anything.

Different meteor showers have different best places to observe, but one thing is certain, the city is not as easy to observe as the countryside, because the light pollution in the city is too serious.

There are many games, and the best place to do so is online.
