8. 13 Can you see the Perseid meteor shower in Tianjin?

In Tianjin, it is very likely that Perseid meteor shower will be seen around August 13- 14.

The area of meteor shower is very small, and the observation conditions of a meteor shower in the whole country are similar. The Gemini meteor shower in 65438+February is one of the three major meteor showers in the whole year, but the maximum value on 65438+February 13 this year is the 16th day of the first lunar month. The phase of the moon is close to 100% and less than 20 from the radiation point, which will affect the observation all night (if you watch the brilliance of the full moon carefully, you will realize that it is fatal to astronomical observation). However, the Gemini meteor shower is active from 65438+February 7 to 18, so we should try to avoid the influence of the full moon. Moreover, there are many bright fireballs in the Gemini meteor shower. If you do visual observation, try to keep your field of vision away from the moon. During photographic observation, attention should be paid to improving the sensitivity and shortening the exposure time, so that the meteor can be submerged by the background skylight illuminated by the full moon as little as possible.

The active period of Perseid meteor shower this year lasts from mid-July to late August, and it will appear extremely in mid-August. According to the forecast of the international meteor organization, the maximum time is likely to be in the early morning of August 13, Beijing time. The moon phase of a day belongs to the first quarter moon, which will have some influence on observers, but there is no moonlight interference in the first half of the night. After Perseus rises, it enters the observable period of meteor shower.

Observe the meteor shower as far as possible in a place without clouds, light pollution and good air quality, any of which will seriously affect the observation effect. You don't have to stare at the radiation point to observe the meteor shower, but you should choose an observation center. There are two conditions for choosing the observation center-close to the radiation point and close to the zenith. Generally speaking, it is better to be about 30 degrees away from the radiation point. Keep an eye on the observation center when observing, don't look around.

65438+65438+05: 30 on February 22nd (accurate forecast, possibly influenced by the earth's movement) is the meteor shower in Ursa minor. The radiant point of the Ursa minor meteor shower is close to the north celestial pole, and the observation conditions are good. For the area around 40 north latitude, the height of radiation point will rise above 30 in the morning 1. The evening of the same day to the early morning of the next day is the ideal observation time for China observers. At this time, the moon phase is a waning moon, rising from the southeast at 3 am, which has little influence on the observation. Moreover, at the beginning of this year, comet 8P Tuttle, the mother comet of the Ursa minor meteor shower, passed the perihelion, so the Ursa minor meteor shower is likely to erupt, so it is more worth looking forward to.

After one o'clock in the morning! Until the sun comes out. Ha ha. It will be cold, so put on more clothes.
