The authors report on conclusions drawn from an extensive study of ground based measurements of the recovery phase of magnetospheric substorms. Much previous work has considered this phase to simply consist of decay processes of growth phase phenomena as the magnetosphere relaxes to its quiescent state. From their studies of observational data the authors conclude that there is evidence of distinct processes within the recovery phase which are related to it alone. These include intense electrojet activity, high-energy particle precipitation, distinct large scale auroral phenomena, and possibly even expanded auroral activity.
