Unusual phenomena in photographic observations of meteor shower

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.
