Increases in the area of coronal holes related to interplanetary shocks
Contenido principal del artículo
Resumen
El rastreo de perturbaciones del viento solar por medio del centelleo interplanetario (IPS) de fuentes estelares de radio mostró que las perturbaciones interplanetarias mas importantes se originan en regiones solares que contienen hoyos coronales. A raíz de esto se sugirió que los choques se originan en hoyos coronales cambiantes que repentinamente emiten viento solar más rápido. En este trabajo presentamos dos casos particulares de observaciones solares e interplanetarias relacionadas con comienzos repentinos de tormentas geomagneticas (SC) en los cuales se muestra que el choque interplantetario está relacionado con un aumento en el área de un hoyo coronal. Los eventos considerados corresponden al 6 de junio de 1979 y al 1º. de octubre de 1991. Se describe un escenario solar para la ocurrencia de estos eventos y se presenta un mecanismo para la formación del choque.
