On December 7, 2000 a joint current sheeth and vorticity layer hit the magnetopause (MP) generating large amplitude oscillations, and wave‐like perturbations observed by CLUSTER at the near dusk flank. Linear stability theory and MHD numerical simulations support the hypothesis that the waves were due to the Kelvin‐Helmholtz (KH) instability. The simulation brings in light novel dynamic properties of the boundary layer under the KH excitation.
