AbstractThe periodicity of high-latitude solar activity has been studied with the use of the Carte Synoptique solar filaments archive. The Morlet wavelet is utilized to analyze the periodicity of the number of solar filaments at latitudes over 50 degrees during Carrington solar rotations 876-1823. For solar filaments at latitudes over 50 degrees, the most eminent periods are about 10.23 and 10.90 years, which correspond to the Schwabe period of high-latitude solar activity, and the these periods make-up a highly significant proportion of the time span considered. The periods of 1.3 and 1.7 years and the quasi-biennial 2-3-year oscillation often mentioned in the literature are not found to be a feature of every solar cycle but seem to appear only from time to time.
