Bonfond et al.  are the first to provide a global description of dawn storms in Jupiter’s aurorae, from their initiation to their end. Their work utilizes comparative planetology, where the authors have compared their observations at Jupiter to observations at Earth. They show that Jupiter’s corotation-dominated magnetosphere has auroral features which combine effects of corotation and solar wind driven tail substorm dipolarization, mapping to ionospheric features visible both by JUNO spacecraft imaging and by the Hubble Space Telescope. This type of study helps us probe and better understand physical processes that affect Earth directly.
