The Catalog is a continuation of the previous five issues which described solar proton events (SPE) from 1970. The Catalog includes the systematized data on SPE with the maximum flux of protons with energy Ep > 10 MeV higher than the value of Jp ≥ 1 cm-2 ∙ s-1 ∙ sr-1 (pfu). There were 142 such events in the solar cycle 23.

In addition to the data on the solar proton fluxes as observed by several spacecraft the Catalog gives information on the particle sources and concomitant X-ray, optic, and radio emission. Integral energy spectrum in the maximum of the intensity-time profile is presented for each SPE.

Unlike previous issues of the Catalog each event is now illustrated by the plots of temporal behavior of X-ray, electron and protons fluxes, solar wind speed, strength of interplanetary magnetic field, and the Dst- index during the time interval around this event.

The data are stored in the World Data Center for Solar-Terrestrial Physics, Moscow ( Data are freely accessible.
