After the introduction of satellites in this subject,&nbsp; auroral science has greatly advanced. This article describes the present understanding the aurora and its explosive nature from the point of view of a series of electrical discharging processes, namely power supply (dynamo), circuit/current and dissipation (auroral phenomena); this is rather a new approach in the search for the secret of the aurora; in the past, many efforts have been focused on moving magnetic field lines. It is shown that the discharge circuit accumulates the power after the dynamo power increases above 10<sup>11 </sup>w, but it becomes unstable when the accumulated power becomes about 10<sup>16</sup> J, thus suddenly unloading it and generating spectacular auroral displays.</p> ER -
