Geomagnetic storm sudden commencements and their possible sources at the sun
Contenido principal del artículo
Resumen
Se analizan seis casos específicos de tormentas geomagnéticas con comienzo repentino (SC) durante 1978 y 1979 con el prop6sito de determinar los eventos solares (ráfagas. erupciones de filamentos 0 fenómenos transitorios en hoyos coronales) que las produjeron. Se utilizan las posiciones obtenidas por Hewish y Bravo (1986) mediante las observaciones de centelleo interplanetario (IPS) para las fuentes de los choques cuya llegada a la Tierra provocó los SCs. Tres de estos eventos fueron ya asociados por otros autores a alguna ráfaga de erupción de filamento y los otros tres no han sido discutidos nunca ya que no hubo nifaga 0 estallido de filamento alguno en todo el Sol durante los cinco días anteriores al inicio del SC. En todos los casos se encontró un hoyo coronal en 0 muy cerca del centro de la regi6n fuente estimada por IPS. Se discute la posibilidad de que ciertos cambios bruscos en los hoyos coronales puedan dar origen a la formación de choques en el medio interplanetario con las características de los observados.
