15. SOLAR COSMIC RAY GROUND-LEVEL EVENT (GLE) ANISOTROPY

The Archimedean spiral configuration in the interplanetary magnetic field controls the energetic particle flow out from the sun. Since it is much easier for a charged particle to propagate along a magnetic field than to cross a magnetic field, solar particle events from solar longitudes that are “well connected” to Earth via this Archimedean spiral path generally have prompt onsets and large...

23. Coronal mass ejections and large solar energetic particle events

The relationship between Coronal mass ejection (CMEs) and large solar energetic particle (SEP) events became well established relatively recently (Kahler et al. 1978; Gosling 1993), not too long after the discovery of CMEs (Tousey, 1973). There was a paradigm shift from flares to CMEs as the main source of SEPs. There are still many questions regarding the CME-SEP relationship, which...
