Abstract

Solar and lunar daily geomagnetic variations provide the basic scientific material for electromagnetic sounding of the Earth at frequencies of 1,2,3,4, cycles per solar or lunar day. The variations also provide information on the upper atmosphere wind movements which give rise to the ionospheric dynamo producing the emf’s driving the current systems. These in turn produce the daily variations.
