Heliospheric particles

WebSolar Energetic Particles (SEPs) can be accelerated during flares and Coronal Mass Ejections up to relativistic energies. In some events 10 GeV protons are produced and, if able to propagate to near-Earth space, these ions may give rise to Ground Level Enhancements (GLEs), recorded by neutron monitors. We model the effect of a wavy … WebObservations show that the heliospheric plasma sheet (HPS) region and its vicinity contain not only the embedded HCS, but also numerous small-scale structures, namely, SMIs …
