We present spectra of a -8 magnitude Perseid fireball obtained by three techniques: a photographic grating spectrograph, a photographic prism spectrograph and a television grating spectrograph. The prism spectrum was used to study the temporal evolution of three representative emissions: the Mg i lines coming from the main spectral component, the Ca ii lines coming from the high temperature component, and the N_2 bands of atmospheric origin. The high temperature component developed around the height of 95 km, which is consistent with the beginning of the formation of meteor shock wave.
