AbstractThe sun has produced several high energy and large fluence solar proton events during solar cycle 22. This recent activity is similar to activity that occurred in the 19th solar cycle before the advent of routine space measurements. In a review of the recent events and a comparison with significant solar proton events of previous solar cycles, it appears that the 20th and 21st solar cycles were deficient in the total fluence of solar particles as detected at the earth. Therefore, when models of maximum solar proton fluxes to be encountered for deep space missions are developed, solar proton data acquired during the present solar cycle should be incorporated.
