Can we see the meteor shower in 2008? (Huaihua, Hunan)
I have answered many questions about meteor shower before, please send them to the landlord again:
There are several points to explain about meteor showers:
First of all, the meteor shower is not like rain as expected. As long as all the meteors come out from one radiation point, it can be considered as a meteor shower. There are nearly 40 meteors every year. Think about how many meteors you can see every year. The meteor shower flow mentioned in the forecast refers to the number of meteors that can be seen at the zenith every hour when the meteor shower reaches its peak, under the conditions of no light, no moonlight, clear weather and no wind. It is very difficult to achieve this condition, so the number of meteors actually seen is greatly reduced. The major meteor showers every year are the quadrant meteor shower around 65438+1October 4th, Lyra meteor shower around April 22nd, Perseid meteor shower around August 13- 14,1October1.
Secondly, it is difficult to predict the meteor shower accurately to hours, because the mass of the material forming the meteor shower is very small, and a little gravitational disturbance will change the time to reach the earth.
Thirdly, never watch the meteor shower with binoculars, just use the naked eye. Using a telescope will seriously affect the effect because of the small field of view received.
Finally, my opinion is that if you don't like astronomy and just want to see meteor storms, then don't hold any hope. In fact, this is largely the result of media reporters' ignorance of astronomy and hype. They think the meteor shower is the same as that in 200 1 year. But if you want to observe, you must go to the wild, at least to the suburbs. Because the light interference in the city will make you see nothing.
