Fig. 2From: Transmission of the electric fields to the low latitude ionosphere in the magnetosphere-ionosphere current circuitQuasi-periodic DP2 magnetic fluctuations observed at high latitude (Nurmijarvi) and equator (Mokolo) with the high correlation (corr. coefficient = 0.9) and no time shift greater than 25 s, indicating near-instantaneous transmission of the convection electric field to the equator.
