On the flux saturation of SOHO/ERNE proton events

Abstract

This study lists the main procedures completed on the analysis of solar proton events using data from the SOHO/ERNE high energy detector in the period 1996$-$2017. The highest possible temporal resolution of 1 minute is used here. The proton fluxes from the two analyzed energy channels, at $\sim$25 and $\sim$50 MeV, are compared with the respective fluxes observed with a similar energy coverage from another proton instrument, Wind/EPACT. The proton events with flux saturation effects are identified and a correction procedure is proposed. Pearson correlation analysis with solar flare class and linear speed of the coronal mass ejections is completed, both with the observed and corrected proton fluxes. The outcomes are presented and discussed.
