From: Transmission of the electric fields to the low latitude ionosphere in the magnetosphere-ionosphere current circuit

The preliminary impulses (PI) at high latitude (PB, CO, SI) and equator (KO), beginning simultaneously within the temporal resolution of 10 s, while no or small PI is observed at mid and low latitudes (FR, TU, HO). The simultaneity of the onset suggests the instantaneous transmission of the polar electric field to the equator (from Fig. 7 of Araki 1977)
