The penetration qualities of an astronomical television system, used for the observation of meteor spectra, are evaluated noting the loss in image brightness caused by velocity and dispersion. On the basis of a previously obtained spectrogram, the possibility of determining meteor angular velocity using a pulsed mode of the TV system's operation is considered. The time-lag of signal fade-out in the television system under actual conditions of meteor spectral observation is measured. It is shown that the spectra of meteor trails may be studied by photographing their images from the screen. Previous spectrographs have exhibited three types of meteor spectra, based on the observability of atmospheric lines and bands.
