The article headline has been simplified a bit[1]; the storms in question are geomagnetic storms[2]. Geomagnetic storms are perturbations of Earth's magnetic field by changes in the solar wind (i.e. solar storms). Having a high-spatial-resolution record of the way the Earth's field changes when interacting with the plasma presumably yields extra insights into how space weather behaves.
