Solar flare electrons at the Sun and near the Earth. Insights from interplanetary transport simulations

We study 15 prompt 3He-rich electron events observed near 1 AU by Wind/3DP above 50 keV. The events are associated with magnetically well-connected flares (between W10 and W85) with rather short soft X-ray duration (~10 min) and HXR sources seen by RHESSI on the visible solar disk. We compare the Wind/3DP observations with the results of interplanetary transport simulations, to infer the properties of the propagation and constrain the injection of solar energetic electrons in the interplanetary medium. We discuss the correlation between the inferred total number of injected electrons with the number of electrons required to produce the observed X-ray flux.
