Upper limit peak proton fluxes (IP, [pfu]) and fluences (FP, [cm−2]) for the SEP event on AD774/775 and GLE05 derived in this work, for each integral proton energy.

AD774/775 GLE05

Integral energy Peak proton flux – IP
(MeV) (pfu) (pfu)
E > 10 2.16E+06 2.36E+05
E > 30 6.38E+05 6.96E+04
E > 60 1.72E+05 1.87E+04
E > 100 5.07E+04 5.53E+03

Integral energy Fluence – FP
(MeV) (cm−2) (cm−2)

E > 10 4.25E+12 3.48E+11
E > 30 1.05E+12 8.56E+10
E > 60 1.46E+11 1.33E+10
E > 100 2.13E+10 2.23E+09

Notes. Peak proton fluxes were calculated via Eq. (2) and fluence via Eq. (3) for a given SXR flux. The upper and lower limits listed here are driven by the FSXR range of the associated solar flare per event, and are from Cliver et al. (2022).
