流星雨摄影观测记录的罕见现象

Unusual Phenomena in Photographic Observations of Meteor Shower

  • 摘要: 2001年狮子座流星雨, 是几百年来难得有机会在中国观测到的一场流星暴。在我们收集到的照相观测资料中, 发现了一些特殊的、还未引起广泛注意的流星现象。"蛇行"的流星以及螺旋形并带有辐条结构的流星余迹, 早在我国古代记录中就可以找到印证。现代的照相技术, 不仅直观地显示了文字难以描述的颜色、形态和变化, 而且提供了可永久性进行测量的记录。其中包括罕见的对流星余迹的双站观测资料。用常规的"高空风作用"难以解释这些观测现象。它们可能反映了流星带电体与地球磁场的相互作用。

     

    Abstract: The Leonid meteor shower in AD 2001 was a great meteor burst inaccessibly happened in China during recent several hundred years. In these photographic observational material collected from all of China by us, some unusual and unnoticed meteoric phenomena in common were found. A meteor "tortuously crawled like a snake" and a meteoric trail, which was spiraling and with "spokes" structure, catch our eyes dramatically, and can be conformed by ancient Chinese records. The modern photographic technique can not only display the color, the configuration and its variation, which is impossible expressed by text, but also provide permanent and measurable records. Among these material meteoric trails observed simultaneously by two stations are peculiar. These phenomena are very hard to be explained by the action of high altitude winds. It may reflect that the meteoric charged body and the Earth's magnetic field interact with each other.
