Abstract
Abstract A possible >30 MeV solar proton intensity–time profile associated with the Carrington solar flare event of 1 September 1859 is constructed. The derived profile is consistent with a >30 MeV proton omni-directional fluence of 1.9 × 10 10 cm −2 found by the analysis of solar proton generated NOy radicals that are deposited in polar ice. The intensity–time profile of the solar particle flux is constructed by assuming that the Carrington solar event is part of the class of interplanetary shock-dominated events where the maximum particle flux is observed as the shock passes the Earth. This assumption is based on the knowledge that the very large solar proton ...
