✦ Synopsis

The data of proton [luences measured in Ihrec ranges of energy ~.alues (I MeV, 10MeV, and 100 MeV) in the current solar cycle 22 have been analysed to detect periodicities. Power spectral analysis of Ihe tirne series of the data of proton Iluences shows a periodicity of 74 days, which conforms to that of olher kinds of solar activity as reported by earlier authors, thus indicalin~ the intitnate relationship of proton emission with sohtr activity.
