Fig. 9From: A brief history of solar-terrestrial physics in AustraliaVector divergence plot showing plasmaspheric duct structure. Positive divergence regions (overdensities) represented by red–yellow hues; negative divergence regions (underdensities) by blue–cyan hues. White represents values close to zero (in FoV). Geomagnetic field lines overplotted as black lines (Loi et al. 2015)Back to article page
