HelioCast: heliospheric forecasting based on white-light observations of the solar corona

Poirier, Nicolas; Kouloumvakos, Athanasios; Indurain, Mikel +8 more

We present a new 3D magnetohydrodynamic (MHD) heliospheric model for space-weather forecasting driven by boundary conditions defined from white-light observations of the solar corona. The model is based on the MHD code PLUTO, constrained by an empirical derivation of the solar wind background properties at 0.1 au. This empirical method uses white-…
