Abstract : The intensities of the polar-glow auroral emissions produced by bombarding protons during a polar cap absorption event are calculated. The observations tend to support Parker's blast model for the propagation of solar flare particles through interplanetary space. The origin of the great auroral displays observed during the large magnetic storms is briefly reviewed.
