Constellation meteor shower

The clockwork meteor shower, which had several wonderful performances in the 20th century, bloomed in the night sky as scheduled.

The 9th is the 29th day of the eighth lunar month, and there is almost no moonlight interference all night. In addition, the radiation point of meteor shower is not falling all night, so there are many meteors that can be seen. So many fans were waiting that night.

Astronomical enthusiasts in Tianjin observed the meteor shower around 10 that night. On some cloudy days, the observation conditions are not very favorable. Nevertheless, more than a dozen meteors were observed in an hour or so, most of which were blue-green and slow.

According to astronomical experts, the mother comet of clockwork meteor shower was named 2 1P, which was discovered by astronomers in 1900, with an operating cycle of 6.6 1 year. At the beginning of last century, the meteor shower in Clockwork was unknown. Until 1933 and 1946, the constellation meteor shower had two extraordinary explosions, making it the most brilliant meteor shower in the 20th century.
