Abstract/Summary

Key Points Eruption of a coronal mass ejection (CME) from an active region on the solar limb may be able cause major terrestrial space weather disturbance Comparison of recent events observed using modern equipment gives key insights on great historic events such as the role of substorms The longitudes at which low‐latitude aurora is seen depends on the Universal Time of the CME impact on Earth's magnetosphere
