Short summary
We investigate the reflection of magnetosonic (MS) waves at the local two-ion cutoff frequency in the outer plasmasphere, which is rarely reported. The observed wave signals demonstrate the reflection at the local two-ion cutoff frequency. From simulations, the waves with small incident angles are more likely to penetrate the thin layer where the group velocity reduces significantly before reflection. These results may help to predict the global distribution of MS waves.
