Open AccessExtreme Solar Events: Setting up a Paradigm
The Sun is magnetically active and often produces eruptive events on different energetic and temporal scales. Until recently, the upper limit of such events was unknown and believed to be roughly represented b...

Open AccessTree-rings reveal two strong solar proton events in 7176 and 5259 BCE
The Sun sporadically produces eruptive events leading to intense fluxes of solar energetic particles (SEPs) that dramatically disrupt the near-Earth radiation environment. Such events have been directly studie...

Open AccessCosmogenic radionuclides reveal an extreme solar particle storm near a solar minimum 9125 years BP
During solar storms, the Sun expels large amounts of energetic particles (SEP) that can react with the Earth’s atmospheric constituents and produce cosmogenic radionuclides such as 14C, 10Be and 36Cl. Here we pre...

Eleven-year solar cycles over the last millennium revealed by radiocarbon in tree rings
The Sun provides the principal energy input into the Earth system and solar variability represents a significant external climate forcing. Although observations of solar activity (sunspots) cover only the last...
