MULTIPHASE PERIODIC VERY-LOW-FREQUENCY EMISSIONS.

Abstract

When periodic very-low-frequency (VLF) emissions of more than one set are observed concurrently (multiphase emissions) the observation of three sets symmetrically spaced is surprisingly frequent. Evidence is presented which suggests that two sets represent a transient situation, and that the strength of one emission may depend on the strength of, and the elasped time since the preceding emission. The data are interpreted as evidence of a relaxation phenomenon in the generation of discrete VLF emissions, and a qualitative explanation of the stability of symmetrical three-phase emission is given.
