Description
Summary:The following notes refer to effects which appear to have a distinct connection with the so-called “ionisation” of the upper regions of the atmosphere by radiations from the sun, and which have repeatedly attracted my attention during the course of recent experiments in wireless telegraphy for the British Postal Telegraphs. In the electronic theory of the causes producing the aurora borealis, it is assumed that by the deflection of the course of the flying ions or electrons towards the poles, due to the earth’s magnetic field, a concentration results in those neighbourhoods, giving rise to the phenomenon.
