Abstract We suggest an explanation of a sharp increase in the abundance of cosmogenic radiocarbon found in tree rings dated AD 775. The increase could originate from high-energy irradiation of the atmosphere by a galactic gamma-ray burst. We argue that, unlike a cosmic ray event, a gamma-ray burst does not necessarily result in a substantial increase in long-lived 10 Be atmospheric production. At the same time, the 36 Cl nuclide would be generated in the amounts detectable in the corresponding… Expand

TLDR
A rapid increase of 14C is observed in an ancient buried tree from BC 3372 to BC 3371, and it is suggested that this event could originate from a large solar proton event. Expand
Causation of Late Quaternary Rapid-increase Radiocarbon Anomalies

TLDR
Evidence is provided that these peaks in the atmospheric radiocarbon (14C) concentration at AD 774/5 and 993/4 were most likely produced by extreme solar events, based on several new annually resolved 10Be measurements from both Arctic and Antarctic ice cores. Expand
