Abstract
THE actual configuration in space-time of micro pulsation activity has long been the subject of controversy, and no single model has been able to explain all the features of the different types of micropulsations. This communication concerns the method by which impulsive Pi2 (ref. 1) micropulsations spread over the Earth. Such micropulsations are recognized more easily on the night side of the Earth, although they can be detected on the daylight side also if not masked by other daylight micropulsations such as Pc3, Pc4 and Pc5 (ref. 1).
