Evolution of the jet in 171 Å. The left-hand column of each block shows log intensity and the right-hand column the unsharp masked log intensities. Top left set of panels: enhanced emission at arcade foot points and observed outflow. Middle left: apparent reconfiguration of the magnetic field and increased emission along the base arcade. Bottom left: rise phase of a loop overlying the base arcade. Top right: formation of jet spire and the rising loop apparently connects with unseen open field. Middle right: initiation of outflowing plasma along the jet spire. Bottom right: elongated jet structure with overplotted cross-cuts used for anlaysis of the kink motion (Online movie).
