Geomagnetic storm
Videos
A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere that is driven by interactions between the magnetosphere and large-scale transient plasma a

GOES-7 monitors space weather conditions during the Great Geomagnetic storm of March 1989. The Moscow neutron monitor recorded the passage of a CME as a drop in levels known as a Forbush decrease.
Solar wind

The solar wind is a stream of charged particles released from the Sun's outermost atmospheric layer, the corona. This plasma mostly consists of electrons, protons and alpha particles with kinetic ener

…regions (CIR). The former often originate from solar active regions, while the latter originate at the boundary between high- and low-speed streams of solar wind. The frequency of geomagnetic storms increases and decreases with the sunspot cycle. During solar maxima, geomagnetic storms occur more often, with the…
Laboratory simulation of the magnetosphere's influence on the solar wind; these aurora-like Birkeland currents were created in a terrella, a magnetised anode globe in an evacuated chamber.
This is thought to show the solar wind from the star L.L. Orionis generating a bow shock (the bright arc).
