Example of a CME with whistler-mode waves. (a) Magnetic field in RTN coordinates and magnitude; (b) solar wind velocity (black) and density (pink); (c) electron temperature anisotropy (black) and beta parallel (blue); and (d) parallel electron heat flux. Vertical blue lines are less coherent whistler-mode waves and vertical gold lines are narrowband whistler-mode waves (examples in bottom panels). Bottom: example 2.1 s waveform capture electric field, one perpendicular to the magnetic field component in red and one parallel component in blue.
