Where space weather starts: Self-consistent propagation of flux ropes in realistic coronal simulations

The effects of space weather extend out across our entire solar system, but this is a simulation of where everything starts: the sudden, violent, emergence of a "flux rope" out of the sun's magnetic field and into the solar wind. In the process flux ropes may bring along millions of tons of plasma from the solar surface to be released into space, known as a Coronal Mass Ejection, or CME.
