摘要
A unique case of two zebra patterns related harmonically with ratio of similar to1:2 was observed by distant radio telescopes at Sao Jose dos Campos and Ondrejov Observatories. Accompanied zebras show that the ratio of frequencies of the neighboring zebra lines is in the range of 1.009-1.037. There is a tendency of a decrease of this ratio with decreasing frequency within the specific zebra pattern. Both facts speak in favour of plasma emission models for the zebra pattern fine structure in radio burst continua.
