Interplanetary coronal mass ejections (ICMEs) are large-scale heliospheric transients that
originate from the Sun. When an ICME is sufficiently faster than the preceding solar wind, a …

Around solar maximum, the dominant interplanetary phenomena causing intense magnetic
storms (Dst<− 100 nT) are the interplanetary manifestations of fast coronal mass ejections …

The 1–2 September 1859 magnetic storm was the most intense in recorded history on the
basis of previously reported ground observations and on newly reduced ground‐based …

Abstract Interplanetary Coronal Mass Ejections (ICMEs), their possible shocks and sheaths,
and co-rotating interaction regions (CIRs) are the primary large-scale heliospheric structures …

We report on a study that compares the properties of magnetic clouds (MCs) during the first
73 months of solar cycles 23 and 24 in order to understand the weak geomagnetic activity in …

The history of geomagnetism is more than 400 years old. Geomagnetic storms as we know
them were discovered about 210 years ago. There has been keen interest in understanding …

Major geomagnetic storms are caused by unusually intense solar wind southward magnetic
fields that impinge upon the Earth's magnetosphere (Dungey, 1961). How can we predict the …

Interplanetary coronal mass ejections (ICMEs) originating from closed field regions on the
Sun are the most energetic phenomenon in the heliosphere. They cause intense …

The explosion of space weather research since the early 1990s has been partly fueled by
the unprecedented, uniform, and extended observations of solar disturbances from space …

During the 7‐year period of the current solar cycle, 64 geoeffective coronal mass ejections
(CMEs) were found to produce major geomagnetic storms (DST<− 100 nT) at the Earth. In …
