Description
VLF-magnetic components (North-South and East-West) originated from lightning discharges received at Pontianak station, Indonesia. Tweek atmospherics are VLF/ELF electromagnetic waves that are originated from lightning discharges and propagate in the Earth-ionosphere waveguide over long distances (several thousand kilometers).
