High-resolution observations and measurements show variability of multi-source solar wind

What drives the solar wind complexity and variability seen in the heliosphere remains an unresolved mystery. Unique high-resolution observations and measurements taken at 0.5 au, coupled with magnetic modelling and spectroscopic techniques, show that the variability is driven by spatio-temporal changes in the magnetic connectivity to multiple solar source regions.
