At about 13:00 on May 31, the Wuxian meteor shower will erupt, which may reach 100000 meteors / hour, forming a meteor rainstorm It is understood that wuxianzuo τ The parent of the meteor shower is comet 73p/ Schwarzman wahlman 3, which was discovered in 1930. It is a short period comet with a period of 5.36 years.

Unlike other short period comets, this comet was lost soon after its discovery, and was not observed again until its return in 1979.
Xiulipeng, member of the Chinese Astronomical Society and director of the Tianjin astronomical society, said that when it returned in 1995, comet SW3 brightened more than 400 times and began to split into five parts. By the time of its return in 2006, astronomers had observed that it had split into at least 65 fragments.
The scientific model shows that at 13:00 on May 31, **
However, astronomers also say that the maximum time of the meteor shower can be predicted, but the flow is "elusive". The international Meteor Organization is very cautious about the forecast of this meteor shower. The zHR value (the number of meteors that can be seen per hour when the radiation point is directly above the head under ideal observation conditions) is currently listed as "unknown".
