Abstract:
We present several case studies of simultaneous multipoint observations of hot ion (~30-2200 keV) injections that occur during substorms in the day- and night-side of magnetosphere from THEMIS, RBSP and MMS probes. We complement them with observations of magnetic field signatures to estimate time delays of earthward plasma flows at multiple probes. We discuss the mechanisms that trigger substorm onset comparing the observations with inner plasma sheet simulations.
