Observation of VLF Phenomena inside the Auroral Zone.

Abstract

The report presents the results of a three-year program of observations and analysis of very low frequency (VLF) radio emissions in the auroral zone. The particular VLF emissions which are the subject of the study are VLF hiss, VLF chorus and extra low frequency (ELF) hiss. All of these emissions occur in the audio frequency range, and the nomenclature of these various emissions is derived from the sounds generated when the undetected signal is fed into a loudspeaker.
