The Earth’s passage of coronal mass ejecta on October 29-31, 2003: ULF geomagnetic field fluttuations at very high latitude
We study ULF geomagnetic field fluctuations detected on October 29-31, 2003, when the Earth’s arrival of solar wind CMEs produced major geomagnetic storms; these solar wind structures are characterized by extremely high plasma speed and long-duration intervals with northward interplanetary magnetic...

Summary: | We study ULF geomagnetic field fluctuations detected on October 29-31, 2003, when the Earth’s arrival of solar wind CMEs produced major geomagnetic storms; these solar wind structures are characterized by extremely high plasma speed and long-duration intervals with northward interplanetary magnetic field. The analyzed geomagnetic field data are from four high latitude stations (three in Antarctica), located deep in the polar cap. The analysis is extended also to low latitude European stations, in order to discriminate between local and global magnetospheric phenomena. Published Monte Porzio Catone 1A.
