AB: Whistler waves inside the magnetopause are found to be generated in thin sheets moving with the plasma drift velocity. In the same region we also observe time-dependent dispersive whistler emissions. The duration of each emission is about 1 second and the frequency ranges from 50 to 150 Hz. Using electric and magnetic wave field observations from the four Cluster satellites we estimate the wave length, the direction of propagation and the size and location of the generation region. We also discuss possible generation mechanisms and their relation to the magnetopause.
