EXTREMELY LOW FREQUENCY RECEPTION AT KINGSTON, R. I.

Abstract

Magnetic fields of natural origin in the 5 to 20 c.p.s. frequency range were recorded in Kingston, R. I. The experimental equipment is described briefly, and results are presented. Variations with time of the first resonant frequency of the earth-ionosphere cavity are indicated, and effects of solar activity are discussed. An analysis of the envelope of recorded wave trains shows only fair agreement with existing theory. (Author)
