AB: We present the first bi-static observations from the SuperDARN CUTLASS radars of naturally occurring ULF wave activity in artificially generated backscatter at 78°N. The backscatter was generated through O mode heating of the F-region ionosphere using the SPEAR high power system, which is located on Svalbard. By merging line-of-sight velocity data from the 2 radars the true ionospheric velocity vector of the flows could be determined and compared with the magnetic perturbations observed on ground magnetometer stations in the vicinity of the heater patch. Two large scale ULF wave events are detailed in this paper. Comparisons of the wave characteristics as observed in the ground magnetometer and radar data are made and discussed.
