[1] Lightning discharges are powerful impulsive sources of electromagnetic energy over a wide bandwidth allowing passive methods to determine lightning location through the energy released by the lightning discharge. While multistation lightning location techniques provide high location accuracy, in some instances it is impossible to deploy a multistation network, and for this reason, techniques have been developed to allow single-station lightning location. We consider the validation of the “Kharkov” single-station lightning location method proposed by Rafalsky et al. [1995a], through comparing the locations of ELF/VLF observed sferics determined by the Kharkov technique with the positions of coincident lightning flashes recorded by a commercial lightning detection network. Making use of 85 sferics observed at Robertson Army Barracks, near Darwin, Australia, in the period from 20 November 1997 until 7 January 1998, we find that that ∼68% of Kharkov method bearing estimates are accurate to within 4.1° and that ∼68% of the Kharkov method range estimates are accurate to within 73.2 km.
