At a slightly uncertain date during the latter part of this decade, there was an extreme [[solar particle event]] comparable with the event detected for AD [[774]]/[[775]]<ref>{{cite journal |title=Multiradionuclide evidence for an extreme solar proton event around 2,610 B.P. (~660 BC) |journal=Proceedings of the National Academy of Sciences |author1=Paschal O'Hare |date=2019 |volume= 116|issue=13 |pages=5961–5966 |doi=10.1073/pnas.1815725116 |pmid=30858311 |pmc=6442557 |bibcode=2019PNAS..116.5961O |doi-access=free }}</ref> The exact date and duration of the event is uncertain due in part to an approximate 2-year residence time of the nuclei generated in the atmosphere, before they "rained out" to be incorporated into tree rings and glacial ice, but the event seems to have happened during the latter part of this decade. The possibility of there being a series of events spread over a period of time remains in consideration. What meteorological and astronomical phenomena would have accompanied this event is unknown. The estimated "brightness" of the event is about 2 orders of magnitude stronger than any that has been recorded instrumentally since the beginning of the Space Age.
