On July 30th, the δ southern meteor shower in Aquarius was the second meteor shower in Aquarius this year.

At the end of July, the Aquarius Southern Meteor Shower will be staged. There are three meteor showers in Aquarius this year. The Aquarius Southern Meteor Shower on July 30th is the second one this year, and the first one was staged in early May. Then let's reveal the details of the Aquarius southern meteor shower on July 30!

The Aquarius Southern Meteor Shower on July 30th is the Aquarius Southern Meteor Shower on July 30th. The maximum zenith flow is 25, and the meteor shower flow is not large. This is the second meteor shower with radiant points in Aquarius within one year. Meteor shower looks like a meteor from a certain point or area in the night sky, and this point is called the radiation point of meteor shower. In order to distinguish different meteor showers, meteor showers are named after the constellations in the sky where the radiant points are located. For example, there will be Perseid meteor shower next month, Gemini meteor shower in 65438+February and so on. Named after the constellation where the radiation point is located.

There are several meteor showers in Aquarius in 2022: Aquarius has three meteor showers with radiant points a year, so it is distinguished by the names of bright stars near the radiant points. The Aquarius meteor shower that appeared in early May is the first meteor shower in Aquarius, and it is a star named after the Greek letter of Aquarius. It is a common method to name the bright stars in the constellation with Greek letters. The radiation points of the other two meteor showers in Aquarius are all near the stars in Aquarius. To further distinguish, the name of the meteor shower is followed by the location. There is a southern meteor shower in the Aquarius triangle and a northern meteor shower in the Aquarius triangle.

When is the best time to observe the southern meteor shower in Aquarius? Suitable for observation after midnight. Aquarius rises above the horizon around 9 pm in Beijing, and it will rise earlier in the south. This meteor shower is more suitable for observation after midnight. Aquarius is basically located in the south of the equator of the celestial sphere, and the star of Aquarius is located in the south of the constellation. Therefore, for people in the northern hemisphere, the position of the radiation point will not rise too high, which will affect the number of meteors seen. There are many other factors that affect the number of meteor showers, such as whether the sky is blocked, whether there is light interference at your observation site, and so on. The influence of moonlight is also an important factor. Strong moonlight will drown dark and bright meteors. When a meteor shower is observed, the moon will not set until midnight on the 30th. But in general, don't expect too much from this meteor shower. The maximum zenith flow forecast is 25. After deducting various influences, the number of meteors seen per hour is only single digits at most.

Too few meteors is not enough? A big meteor shower is coming! It is worth mentioning that at the end of July and the beginning of August, several other meteor showers near the ecliptic south of the celestial equator were relatively active, including the reverse meteor shower, the Alpha meteor shower in Capricorn and the Southern Pisces meteor shower. In addition, the Perseid meteor shower, which will peak in the middle of next month, will also start activities at this time. Although the flow of these meteors is not large, the total number of meteors will increase when several meteors are superimposed together.

It is easy to distinguish these different meteor groups, that is, to judge where the meteors are emitted. Just because meteors can appear anywhere in the sky doesn't mean that the meteor shower in Aquarius must appear in Aquarius. After seeing a meteor appear, extend the meteor in the opposite direction and trace the backward extension line to which radiation point, so as to determine which meteor shower the meteor belongs to.

Aquarius is one of the famous zodiac signs, which is generally called Aquarius in astrology. The most suitable season for observation is autumn. Located between Capricorn and Pegasus, the constellation is very big, but there are few bright stars. There are only three third-class stars and more than a dozen fourth-class stars. It is very difficult to identify them. You can hardly see them in a brightly lit city. On the classical star map, the stars in the constellation are depicted as a beautiful young man holding a vase and pouring water into the sky. This beautiful young man is Ganymetes, the waiter in charge of pouring wine when the gods held a banquet in ancient Greek mythology. Zeus often held banquets at the temple of Olympus. Traditionally, the unmarried daughter of the host should be responsible for providing tea and wine at the banquet. Princess Heber, the daughter of Zeus before, shuttled between the gods, constantly pouring jade liquid and adding nectar to everyone.

Later, Princess Herb married Hercules, a hero, and was no longer suitable for this job. The pourer disappeared at God's party. So Zeus became an eagle and came to the world to find the right person. Among a group of playful children, he found a beautiful prince and a beautiful teenager, Ganymetes. Zeus's eyes sparkled in front of the children. Brave Ganymede was not intimidated by the eagle, but turned over and rode on its back. At this time, Zeus spread his wings and took off, flying into the sky with a beautiful teenager, taking over the job of Princess Herb and becoming a waiter at the feast. This is Aquarius. The eagle incarnated by Zeus became Aquila.
