Abstract

Theoretical estimates of the acceleration times of solar electrons and protons during the process of “magnetic detonation” — the development of eruptive flares — are made. The relationship between the acceleration rate and the energy of the first protons arriving in the Earth’s orbit is studied using the example of observations of four events in May–June 2024. Eruptive flares (proton and non-proton) can be classified by the electric field strength (by the time of electron acceleration to 100 keV and the moment of arrival of the first protons) and the duration of observation of electron radiation above 100 keV (the time available for proton acceleration >100 MeV).
