A comparison between the Jupiter dawn-storm-related event and Earth substorm-related event. (a) The magnetic field B _θ and B _R components (in Jupiter-De-Spun-Sun coordinate) for the Jupiter event on 2017 May 16, observed by Juno spacecraft. (b) The measurements of the magnetic field B _Z component (in Geocentric-Solar-Magnetospheric coordinate) for the Earth event on 2015 December 20 by THEMIS P5, and B _lobe, inferred from total plasma pressure at P5 assumed to be in pressure balance with the lobe (magnetic) pressure (Angelopoulos et al. 2020).
