The role of CMEs in the lateral spread of electron events in the inner heliosphere

This work focuses on the study of the role played by solar wind transient events in the longitudinal spread of particles during some SEP events. We have selected SEP events observed simultaneously by STEREO and/or ACE/Wind that show an increase in the flux of nearly relativistic electrons. We combine in situ and remote sensing analysis to identify the 3D morphology, position, and kinematics of CMEs that could facilitate the lateral spread.
