An event showing the superposition of a transverse ion cyclotron wave and a compressional mirror mode for R outside 6 R S on October 13, 2009. a Perturbed magnetic field components in KRTP coordinates, B 0 ~58 nT, and b left-hand circular polarization in the transverse magnetic components. c The mixture of the parallel compressional mirror mode and the transverse ICW magnetic components. The red point denotes the start time and the blue point denotes the end time
