For GLEs,mean values are 3.5 Rs and 11.5 Rs, respectively. (Gopalswamy et al.,2005)Height of CME at the moment 175-315 keV electron’s release is~3.4 Rs.
Protons have to be accelerated up torelativistic energies before 06:40 SolarTime, i.e. when CME was lower than 2-22.3 Rs.Prompt appearance of the high-energyparticles requires that a strong shockwith a large compression ratio occursvery early and relatively close to theSun (
