The visible spectrum of a bright Leonid bolide was recorded and analyzed by fitting the parameters of a newly developed numerical plasma model. In this procedure, elemental composition, electron density, plasma temperature, and the density of the heavy particles were extracted from the observed spectrum. The model introduced in this study involves self-absorption and takes into account the effects of the non-homogeneous meteoric plasma on the observed emission spectra using a simple radiative transfer model.
