Connectivity of solar storms – STORMGENESIS

Solar storms are a spectacular manifestation of the dynamics of our star. Coronal mass ejections consist of giant magnetic structures expanding rapidly in the solar atmosphere and then propagating in the heliosphere. They can impact the space environment of solar system planets, and perturb significantly our magnetosphere. Their understanding requires to link solar activity on the solar surface, in the solar corona, and in the heliosphere. This is the goal of STORMGENESIS. We will characterize the initiation, propagation and connectivity of solar storms based on innovative and ambitious numerical modelling combined with the latest multi-spacecraft observations. The STORMGENESIS project will therefore provide key physical insights into the most important space weather events, in the new golden age of heliospheric observations offered by Parker Solar Probe and Solar Orbiter.
