A new study just released indicates the June 2012 discovery by
a team of Japanese scientists showing a spike in carbon-14 found in tree rings
dating between 774-775 AD – was most likely caused by a CME (coronal mass
ejection). Until now, the 1859 “Carrington Event” has been
documented as the largest solar event to hit Earth ever recorded.
A research team lead by Adrian Melott, Professor of Physics and Astronomy at the University of Kansas and Brian Thomas, Professor of Physics and Astronomy at Washburn University, have examined the evidence and zeroed in on the likely source of
the 774-775 AD carbon-14 event.
It was noted that recent observations of stars similar to the Sun made by the Kepler satellite suggest that they are flaring at levels similar to that which they
suggest – and higher – at average intervals of a few hundred to thousand years.
This new discovery has been titled the “Charlemagne Event” – named after Charlemagne’s victory over the Lombards during the same period. “What our team concluded was the Charlemagne Event would be 10 or 20 times greater than the Carrington Event of 1859″.
