After the beginning of autumn, the weather gradually became cool, especially when watching stars at night, there would even be a burst of coolness, so pay attention to keeping warm when watching stargazing. The starry sky in August is wonderful. In addition to the previous planets and star sky, tomorrow, we will usher in a "star -rated" meteor shower, which is worth looking forward to.

August 12 Yingxian Meteor Shower

The Yingxian Meteor Shower is one of the three largest meteor shower in the northern hemisphere, and the other two are Gemini Meteor Shower and Elephant Meteor Meteor Shower. Both meteor shower occurs in the coldest winter in the northern hemisphere, which is not easy to observe. The Yingxian meteor shower appears in summer, and the observation conditions are relatively comfortable.

The active time of Yingxian's meteor shower from July 17th to August 24th, which lasted more than a month. Generally, the meteor traffic reached a large amount of meteor flow around August 13, and the maximum sky traffic could reach more than 100 per hour. This year, the great period of the Yingxian Meteor Shower Forecast appeared in the early morning of August 13, Beijing time, so it was more suitable for watching from the evening of the 12th to the early morning of the 13th.

In this season, shortly after dark, Yingxian will rise from the horizon of the northeast. At this time, the meteor rain radiation point is low, and the number of meteors can be seen will not be too much; near midnight, the Yingxian seat has risen to rise. In the air, the number of meteors that can be seen will increase; after midnight, the radiation point of meteor shower will continue to rise. At this time, it will usher in the great period of meteor shower, which is the best time to observe.

However, the impact of the city's light interference on observation of meteor shower is still great, so it is best to choose the suburbs. In addition, this year's Yingxian meteor shower coincides with the full moon, and the strong light of the full moon will seriously affect the observation of meteor shower. Some darkest meters will be submerged in the moonlight, and the number of meteors that can be observed will be greatly reduced.

It should also be reminded that the safety of watching meteor shower is the first place. You must be familiar with the observation location in advance and pay attention to bringing warm clothes. In addition, mosquito bite in summer is also a trouble, it is best to bring mosquito -repellent drugs.

Observation of meteor shower generally does not need to carry any equipment. This is because the visual range of the telescope is too small, but it is not suitable to observe meteor. At that time, meteors may appear in any direction in the sky, so the field of vision must be widened. To remind everyone, standing up and watching meteor shower, it will soon be sour around the neck, and it will be more comfortable to take a sitting or lying posture, so it is best to prepare a chair or moisture pad.

The meteor speed that belongs to the Yingxian Meteor Group is as high as 59 kilometers per second, and the time to pass the night sky is only a few seconds. It is fleeting. It may disappear if you exclaim. However, after some of the brighter meteors flashed, there will still be more than a few seconds, and "convenient" people wish.
