Contribución del Observatorio del Ebro al Servicio Internacional de Variaciones Magnéticas Rápidas de la IAGA

Abstract

The rapid magnetic variations constitute a preferential research field inside the terrestrial magnetism of external origin. The origin of these variations has to be placed in the solar activity and its fluctuations. The Ebre Observatory, following its foundational research line, has been participating very actively in the development of the knowledge of the rapid magnetic variations in both theoretical and practical works, from its foundation. It has been also strongly involved in the organizing activity by taking part in committees and international organizations created to foster its knowledge, which culminated with the acceptance of assuming the International Service of Rapid Magnetic Variations. In this paper we make a historical survey of these actions in the framework of the international movements that drove its development.
