Can you see the 0/3 meteor shower in Tongcheng/KLOC-Anhui in August 2009?

Meteor shower has no obvious regional characteristics. Perseus is the north star, which can be seen in the northern hemisphere, mainly because of weather conditions.

Meteor shower name: Perseid meteor shower

Comet matrix: 109 p/ Swift-tuttle

Radiant point: Perseus

Estimated date: 12-13.

Description: the flow rate is large, and the peak flow rate is about 60 per hour. Low brightness requires patience when observing.

In China, two mornings can be observed continuously: one is from 12 in August to before dawn; The other is from 0: 00 am to before dawn on August 13. Two mornings: in the first morning, the eastern part of China was basically unaffected by moonlight, but the number of meteors observed was relatively small; The first half of the next morning was slightly disturbed by moonlight, but the number of meteors observed was relatively large.

1. Maximum estimate: around 0: 40 and 5: 30 on 13.

2. Observation direction: The radiant point of Perseid meteor shower in the northeast of the sky will not rise from the horizon until 22 o'clock, and will rise even higher in the middle of the night.

The best observation time this year is in the dark night sky a few hours before dawn on August 12. If the day is cloudy, the observations on 1 1 and 13 are also important. Try observing in the middle of the night before the moon rises. Unfortunately, the height of the radiation point was still very low at that time, and only a few meteors in the group could be observed. At this time, the meteors observed in Perseus meteor group usually have long trajectories and produce meteor trails, but this situation is rare.

The active period of Perseid meteor shower this year lasts from mid-July to late August, and it will be extremely prosperous 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. It is difficult to accurately predict the hour of meteor shower, because the mass of the material forming meteor shower is very small, and a little gravitational disturbance will change the time to reach the earth.

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.
