Scientific paper

The Hawkes and Jones (1975, 1980) theory for the prediction of dustball meteor ablation has been tested using data from two-station TV observations made during the 1977 and 1978 displays of the Perseid meteor shower. End heights were found to be independent of meteor magnitude, with a mean beginning height value of 110 + or - 1 km. End heights and heights of maximum brightness were found to be independent of meteor magnitude only up to a critical magnitude, and their mean values were 99 + or - 1 km and 103 + or - 1 km, respectively. For meteors brighter than the critical magnitude, end and maximum brightness heights were on average significantly lower than the mean levels, in agreement with dustball theory. It is suggested that the Perseid material is weaker than that considered in dustball ablation theory.
