In which direction is the 2022 auriga meteor shower?
The best viewing direction of Auriga meteor shower is the southeast sky. That night, if the weather is clear and there is no moon, you can observe it in a place with less light pollution. It is expected to be between 22: 40 on September 1 day and 0: 30 on September 2.
How many Auriga meteor showers will there be every hour in 2022?
The theoretical peak flow is about 100 meteors per hour, and there are many bright meteors, which is also very friendly to non-professional observers. However, compared with the Perseid meteor shower that appeared in August of 13, it was much inferior.
How did the Auriga meteor shower get its name?
Legend has it that the shepherd Auric Tonios is the son of Vulcan hephaestus. He is as clever as his father, but he is lame. In the battle with the monster giant, he invented the four-wheeled chariot, which contributed to the victory. In order to reward him, Zeus promoted him to the sky and became Auriga.
Observations and precautions:
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 rules, as follows:
First of all, the number of meteors is related to their size. For weak meteors invisible to the naked eye, the average number of meteors will increase by two for every decrease in magnitude (because stars with small magnitude are brighter, it is customary in astronomy to call magnitude increase as decrease). Five times. That is, the smaller the mass of meteoroids, the more they are.
Second, in the same day, the probability of meteors appearing before dawn is the highest, and the probability of meteors appearing in the evening is the lowest, that is, there are more meteors in the second half of the night than in the first half 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 meteors 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.

Meteor shower observation
Preparation before observation: First of all, you should be familiar with the starry sky, know the constellations around the meteor shower radiation point and the names of the main stars, and also prepare star maps, record sheets, pens, small flashlights (wrapped in red cloth or red paper), calibrated clocks and other necessary supplies, as well as cold-proof and dew-proof items such as seats and clothes.
When observing, count the meteors. If you observe in pairs, 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, so you can prepare a small notebook. When you see a fashion, draw a line on the notebook with a pencil and count the number of strokes divided by the time interval to get the ratio of seeing meteors. Record the start and end times when counting.
Observing meteor showers can also be used to photograph the beauty of meteor showers. A camera with B-door and high-sensitivity film is needed for shooting. 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 generally does not exceed 5 minutes. This method can be described as "waiting for the rabbit".
