Second EPD reconnection event on 28 September 2002. All-sky images of the OI 630.0 nm (left column) and OI 777.4 nm (right column) emissions observed on 28 September 2002. (X, Y, Z) denote EPD structures involved in the second EPD reconnection event. (a,d) Y-Z connected, the arrow indicates the site of an EPD bifurcation. (b,e) Z disconnected from Y, the arrow indicates the site of disconnection. (c,f) X-Z reconnected, the arrow indicates the site of reconnection. The ellipses encircle the regions of dynamical interaction of EPD structures (X, Y, Z). The two Supplementary Videos provide a clearer view of EPD interactions.
