During the 1977 and 1978 Perseid showers, seventeen meteors were simultaneously photographed with a spectrograph and with a camera equipped with a rotating shutter. Of the eight best examples, the half in whose spectra the forbidden line of neutral oxygen at λ5577 was relatively strongest appeared and disappeared at heights about 9 km. greater than did the half in whose spectra the line at λ5577 was relatively weak. Structural or compositional differences in the meteoroidal particles appear to be the most likely explanation for these height variations. A by-product of the investigation was an average value of −8.8 km/sec2 for the deceleration of the meteors over the observed trajectories.
