Abstract
The anisotropic radiation of infrasonic waves from moving aurorae is explained by a shock wave model. The acoustic waves, as observed on the ground at a site ahead of the moving aurora, are amplified in the direction parallel to the auroral motion by superposition of wave fronts if the auroral form is moving at supersonic speed.
