Height analyses of short-duration meteor trains

Abstract

Just after the appearance of meteors within an altitude range from 90 km up to120 km, faint luminescence can be usually observed as short-duration meteor trains, followed by persistent meteor trains in case of extremely bright parent meteors. In a recent study of trajectory analyses of the Leonids storm in 2001(Shigeno et al., 2003), considerable examples of short-duration train movies are found in their precise double-station video observations.
