The first meteor shower of the new year is coming, which areas can be seen clearly?

The reporter learned today from the Science Department of Purple Mountain Observatory of China Academy of Sciences that a series of wonderful astronomical phenomena will appear in the coming month in 2002 1 and1. Meteor shower, planetary division, east distance of mercury, are you looking forward to the first meteor shower in the new year? Who do you want to go with? Hu, an engineer from Zitong Science and Technology Department, said that the quadrant meteor shower based on the asteroid eh 1 in 2003 will usher in the maximum cycle at 22: 30 on October 3, 65438/KLOC-0. According to the forecast data of the international meteor organization, the zenith time in the maximum period can reach 1 10, that is, the number of possible meteors per hour is 1 10.

The quadrant meteor shower is the first of the three major meteor showers in the northern hemisphere, and it is also the earliest meteor shower that appears every year. Although its zHR is similar to the Perseid meteor shower in August and the Gemini meteor shower in June and February of 5438, the quadrant meteor shower is not as common as the other two meteor showers. This is because the maximum period of quadrant meteor shower is very short, usually only 6-8 hours. If there is no sunny night for the longest time, it will have to wait until next year. Quadrant meteor showers often have very bright Mars, so they are also worth looking forward to.

The radiant point of quadrant meteor shower is located in the shogunate constellation under the handle of the Big Dipper. The evening of 65438+ 10 is the 20th day of the lunar calendar, and the rising time of the moon in the lunar calendar 19.2 is earlier than the radiation point. Moonlight has a great influence on the observation of meteor showers. When observing, you can choose to avoid the moon and avoid the moonlight from entering the line of sight. Taking Nanjing as an example, the rising time of the moon is 2 1:29, and the rising time of the radiant point of the quadrant meteor shower is 23: 18. You can choose to watch the meteor shower at midnight.

Astronomers use celestial coordinates to study the position and motion of celestial bodies. They can use the equatorial coordinate system composed of right ascension and declination to determine the position of celestial bodies, which is similar to the latitude and longitude of the earth. When the right ascension directions of two celestial bodies A and B are the same, they are called two celestial bodies A and B, and there are * * * identical intersections between the big planets and between the big planets and the moon.
