Abstract: | We have analyzed the meteor records in the chronicles of the east Asian countries, especially the Korean records. Our results
show that the seasonal variation of sporadic meteors has persisted at least for the last two millennia. We also observed the
prominent showers such as the Perseids and the Leonids, which are formed by Halley-type comets. We obtained the regression
rate of nodal points for the Leonids to be approximately 1.52± 0.04 days per century. |
