Juno observations of energetic electrons and plasma waves on 16 July 2018. (a) Magnetic field strength and rate of change (<em>dB/dt</em>); (b) Energy spectrogram of electron fluxes from 30 keV to 1 MeV observed by JEDI; (c) Energy spectrogram of electron fluxes at energies from 100 eV to 30 keV observed by JADE; (d-e) Pitch angle distributions of electron fluxes at 98 keV and 32 keV; (f) Wave electric spectrogram at frequencies from 20 to 150 kHz, where the white dashed line is the local electron gyrofrequency and the orange dotted line is the modeled plasma frequency; (g-h) Wave electric and magnetic field power spectrograms at frequencies from 1 to 20 kHz, where the white solid line is the left-hand cutoff frequency (<em>f</em>L=0) and the orange solid line is the calculated plasma frequency based on <em>f</em>L=0.
