Solar energetic particle events are observed at Earth following some but not all major solar flares. While there is a statistically higher probability that energetic particles will follow a flare on the western side of the solar disk, which is understood to result from the average interplanetary magnetic field (IMF) configuration, what causes a particular solar flare to generate an energetic particle event near Earth is poorly understood. In order to explore the concept of magnetic connectivity further, we are using a coronal potential field source surface and Schatten current sheet model coupled to a heliospheric magnetohydrodynamic model, the WSA-Enlil coupled model, to determine the location of the footpoint on the sun of the IMF field line that passes close to Earth. We explore whether the probability of a solar energetic particle event near Earth is influenced by distance of the flare location from the Earth-connected IMF magnetic footpoint. We present preliminary results and statistical analysis for sixteen Carrington Rotations, including 20 X class solar flare events that resulted in solar energetic particle events near Earth.
