Short summary
Our research explores a new method for identifying where and when the magnetic field lines in Earth's magnetotail may change its topology through the reconnection process, during which a sudden release of magnetic energy can lead to the brightening of aurora, a process called substorm. Traditionally, the magnetic reconnection was often interpreted using a two-dimensional model, which however does not capture the intrinsically three-dimensional nature of reconnection physics, as we have revealed.
