• A maximum entropy method (MEM) spectral analysis is made of the number of historically recorded meteorite falls in China from AD 619 to 1943 and the number of witnessed falls in the world during the period from 1800 to 1974. The presence of a 60 year period as suggested by previous workers, CHANG and YU (Mem. Natl Inst. Polar Res., Spec. Issue, 20,276,1981), is confirmed as a common feature of meteorite fall rate. In this paper the period is determined to be between 60 and 63 years. A periodicity of 240 years, also previously noted, is unstable in spectral analysis, suggesting that this periodicity may not exist. The presence of two more periodic components : ∿10.6 years and ∿17.7 years in meteorite flux is indicated from the power spectrum.
