1. Perseid meteor shower
Perseid meteor shower occurs regularly from July 17 to August 24 every year. It is not only rich, but also almost never misses the starry sky in summer. It is the most suitable meteor shower for non-professional meteor observers, ranking first among the three periodic meteor showers in the whole year. Comet Swift-Tuttle is the mother of Perseid meteor shower. 1992 around the perihelion of the comet, the Perseid meteor shower shone brilliantly, and the number of meteors reached more than 400 per hour.
2. Dragon meteor
The Draco meteor shower occurs every year from June 6th to June 6th of 10, and the maximum day is June 8th of 10. This meteor shower is one of the three periodic meteor showers in the whole year, with the maximum hourly discharge of 120, and the maximum day is generally close to the new moon, which is less affected by moonlight and provides good observation conditions for observers.
3. Leonid meteor shower
Leonid meteor shower occurs every year from 165438+ 10/4 to 2 1. Generally speaking, the number of meteors is about 10 to 15 per hour, but the Leonid meteor shower has a peak every 33 to 34 years, and the number of meteors can exceed several thousand per hour.
The favorable observation time of Leonid meteor shower this year is165438+1October 17-20, especially around 5: 49 on the 20th, and there may be an "outbreak" of Leonid meteor shower. By then, there will be dozens to 500 meteors across the sky every hour.
4. Gemini meteor shower
Gemini meteor shower appears from June 13 to June 14 every year, and the maximum hourly flow can reach 120, and the maximum flow duration is long.
In 2009, the Gemini meteor shower will reach its peak in the early morning of 15, and the maximum number of theoretical meteors per hour can reach 120. Gemini meteor shower is very suitable for observation, not only the meteor is slow, but also the bright meteor will leave a white trail.
Remind the landlord:
1. The meteor shower should be observed directly with the naked eye. Because observing meteor showers requires a wide field of vision, if telescopes are used, the field of vision will be greatly reduced and the number of meteors observed will be greatly reduced. Moreover, the meteor you see can only be seen in the lens, and you can't see anything clearly. Therefore, it is best not to use telescopes when observing meteor showers, but only use our eyes and a clear and dark sky.
2. It is best not to observe in the urban area, because there are too many artificial light sources in the urban area, which seriously affects the observation effect. If possible, it is best to go to the suburbs and choose an empty and dark venue.
3. Be patient. If you like astronomy, you have to put up with some disadvantages. Observing the meteor shower does not mean that the number of meteors is like rain. Generally speaking, no matter how big the meteor shower is, only a few meteors can be seen on average in 1 minute, and in rare cases, it may reach more than a dozen. When observing, keep an eye on the sky near the radiation point and keep observing. Don't look around because you lose patience, you may miss a wonderful scene.
4. Pay attention to cold and warmth. Meteor showers in the second half of the year are mostly in winter. Tangshan is located in North China, when the temperature will drop below zero, it may take several hours to observe the meteor shower, so be sure to keep warm.
Good luck to the landlord!
