Abstract
48.5 kHz signals from a transmitter in Silver Creek, Nebraska, propaga ting to Huntsville (HU), Alabama over a approximately 1200 km Great Ci rcle Path (GCP) exhibit characteristic amplitude changes which appear within 20 ms of cloud-to-ground (CG) flashes located within 50 km of t he path. Data are consistent with the heating of ionospheric electrons by the electromagnetic (EM) pulse from lightning producing ionization changes in the D-region over the thunderstorm.
