Description

A Ground-Level Enhancement (GLE) was detected on May 11, 2024, following a significant Forbush decrease. Simultaneously, a powerful Solar Energetic Particle (SEP) event was measured at the Lagrange L1 point and by the Solar-Terrestrial Relations Observatory Ahead (STEREO-A). This event was triggered by an X5.8 flare and a fast Coronal Mass Ejection (CME) with a speed >1500 km/s which generated a shock wave in the solar corona.
We modelled this coronal shock wave using a 3D reconstruction technique and a magneto-hydrodynamic model. The results of this reconstruction are presented with an observational analysis of the SEP event and electromagnetic signatures. This work was coordinated under the Horizon Europe SPEARHEAD project.
