Description: Very Low Frequency (VLF) spectrograms show
sometimes sets of lines called MLR (Magnetospheric Line
Radiation) with frequency spacing close to 50 or 60 Hz. It is
very tempting to attribute these MLR to Power Line
Harmonic Radiation (PLHR). PLHR are the ELF and VLF
waves radiated by electric power systems at the harmonic
frequencies of 50 or 60 Hz. Here we show for the first
time large scale MLR observed simultaneously on
ground and on board a low altitude satellite which is
flying over the same zone.
