According to the astronomical popular science experts, on July 30, the Bottle seat Δ South Meteor Shower was extremely large, and the observation conditions were good.

Treasure bottle Δ Nanmei Shower is also called Nanbao Bottle Δ Meteor Shower. It is one of the medium -sized meteor showers fixed every year. The active period is longer. Song Yuanyuan, a member of the Tianjin Astronomical Society and an astronomical popular science expert of the Tianjin Science and Technology Museum, introduced that in the year, there were three times in the meteor shower in the treasure bottle seat. In order to distinguish these three meteor shower, the name of the bright star near the radiation point will be added.

The first time is the meteor shower of the Baotao seat. It appears around April 19th to May 28th each year. It reaches the climax around May 6th. His mother is a well -known Comet Harley. From July 12th to August 23rd each year, it will usher in the prosperity around July 30. The mother's body is unclear. The most likely candidate is Comet 96P/Mek Herz; the third time is the treasure bottle seat. Δ Beiliu Star Rain appears around July 15th to August 25th each year. It ushered in greatly on August 8th, and the mother's body is unclear. Among them, the traffic of the meteor shower of the Baode is the largest. ZHR (under ideal observation conditions, the radiation point is directly above the head, the number of meteors can be seen per hour) is about 50.

Astronomical forecast shows that the peak of the rain bottle Δ southern star rain this year is expected to occur on July 30, and it may last until July 31. ZHR will be 25; after the radiation point is dark, it will rise from the Oriental Horizon. It can be seen all night.

"The southern meteor rain in the southern hemisphere is one of the main meteor shower in the southern hemisphere. For observer in the northern hemisphere, its radiation point will never rise too high, so the traffic will be discounted. Big, but this year's meteor shower is extremely big, there is no moonlight interference, which means that when the weather is fine, the observation conditions are almost perfect. The public who likes meteor shower can try to observe. "Song Yuanyuan said.

Around the end of July, there were Capricorn α meteor shower, southern fish meteor rain, July Tianlongzhan γ meteor shower, etc. "Although the traffic of these meteor shower is not very large, but with the overlapping of the southern meteor rain in the Bao Bottle Δ, the overall number of meteors will increase, and the public will be even more likely to see the meteor through the night sky." Song Yuanyuan said.
