Fig. 5From: Subpacket structure in strong VLF chorus rising tones: characteristics and consequences for relativistic electron accelerationSharp electron injections occurred at the (n = 1) cyclotron resonant energies associated with the growth of the chorus elements shown in Fig. 2 (a MagEIS 54-keV electrons) and Fig. 4 (b HOPE 9.25-keV electrons). The observation times of the chorus rising tones are indicated by dashed linesBack to article page
