The Super Dual Auroral Radar Network (SuperDARN) is a useful tool for the study of field line resonances (FLRs) in the Earth’s magnetosphere. When simultaneous measurements are made by overlapping pairs of SuperDARN radars the 2D flow vectors associated with an FLR event can be determined. Two FLR events, a low azimuthal wave number (m) event and a high-m event, have been observed with the overlapping Saskatoon and Kapuskasing radar pair. The 2D ionospheric velocity fields associated with each individual FLR have been determined. It is found that both high and low-m FLRs exhibit vortex type flow with the low-m vortices aligning in a north-south direction and the high-m vortices aligning in an east-west direction. The reason for the vortex-type flow structure will be discussed. The FLR flow velocities are also used to estimate 2D maps of field aligned currents associated with the high and low-m FLRs. These field aligned current maps can be used to infer auroral structure associated with FLRs of different azimuthal wave number.
