202 1 meteor shower schedule forecast 202 1 when will there be a meteor shower?

Meteor shower is a romantic astronomical phenomenon, and it is very beautiful, so it also attracts many people's yearning for it. If you want to observe each meteor shower better, it is very important to know the time of each meteor shower. So the following is the 202 1 meteor shower schedule announced by constellation knowledge!

The Gemini meteor shower peaked at 5 o'clock and the Ursa minor meteor shower peaked at 23 o'clock on February 22.

The observation methods of meteor shower include: visual observation, photographic observation, spectral observation, photoelectric observation, TV observation, radar observation, space observation and so on. But amateurs often use visual observation and photographic observation. According to long-term observation, the appearance of meteors in the sky has certain regularity, which is as follows: First, the number of meteors is related to their size. For dark meteors invisible to the naked eye, the average number of meteors will increase by 2 for every step of magnitude reduction. Five times. That is, the smaller the mass of meteoroids, the greater the number. Second, on the same day, the probability of meteors appearing is the largest before dawn and the smallest in the evening, that is, there are more meteors in the middle of the night than in the middle of the night. In the same year, there were more meteors in the second half of the year than in the first half, and more in autumn than in spring. Although the number of meteors falling on the earth every day will have different results due to different observation methods, it can generally reflect that some laws are similar.

Preparation before visual observation and photographic observation: First, you should be familiar with the starry sky, know the names of constellations and main stars around the meteor shower radiation point, and prepare necessary items such as star map, record sheet, pen, small flashlight, calibrated clock, chair and clothes. When observing, count the meteors. If two people observe, one counts the number of meteors and the other records the time and the number of meteors. Sometimes there are too many meteors to remember. You can prepare a small notebook. When you see something popular, you draw a pencil in your notebook. Count the number of strokes and divide by the time interval to get the meteor rate. Calculate the start and end time of the record. Observing meteor showers can also be used to photograph the beauty of meteor showers. You need a B-door camera and high-sensitivity film. The specific shooting method is: fix the camera on a stable tripod, set the focal length of the lens to infinity, open the aperture to the maximum, and then aim at the selected sky area to start exposure. Each exposure time is generally shorter than 5 minutes. This method can be described as "waiting for the rabbit".
