#CarringtonEvent #MiyakeEvents
"Miyake was not researching the Carrington event, but something bigger and more distant. Thanks to previous research, she knew there had been a pronounced carbon-14 spike sometime in the late eighth century. Eventually, she found an unmistakable signal: Between 774–775 AD, she noted a 12 percent jump in carbon-14 that suggested an event twenty times larger than ordinary cosmic phenomena. Other researchers confirmed Miyake’s findings with European and North American trees. Scientists found a similar signal in beryllium isotopes present in Antarctic ice cores. The collective findings provided abundant evidence that the event in question was a global, rather than a local, phenomenon.
(. . .)
Miyake and her team published their results in Nature in 2012. Since then, more 'Miyake events'—characterized by sudden, single-year leaps in the concentration of carbon-14 in trees, as well as beryllium-10 and chlorine-36 in ice sheets—have been confirmed in 7176 BC, 5410 BC, 5259 BC, 774 AD, and 993 AD.
Miyake events exhibit significantly greater intensity than the solar or stellar events that could have triggered the Carrington event in 1859. 'Those two scintillating days in 1859 are barely a blip,' Charlotte Person, a dendrochronologist at the University of Arizona, told Science. The carbon-14 stored in tree rings that year barely surged at all."

What if a #solar storm a thousand times stronger than any recorded hit Earth today? Imagine a surge of #energy from the #cosmos so powerful that it leaves its mark not only on our #atmosphere but also etched into the very rings of ancient #trees.

The solar system occasionally hits the “off” button for (electronic) technology. Estimates based on “recent” data suggest we are overdue for the next occurrence, but we really don’t know when it will occur.
Biology survives the events.

#MiyakeEvents als absolutchronologische Fixpunkte #dendrodatierter Holzbefunde:
"Schweizer Forschern ist es erstmals gelungen, eine über 7.000 Jahre alte Siedlung in Griechenland jahrgenau zu datieren. Dafür kombinierten sie #Jahrringmessungen an Gebäudeteilen aus Holz mit dem plötzlichen Anstieg von Partikeln aus kosmischer Strahlung im Jahr 5259 v. Chr."

Nine such extreme #solarstorms—known as #MiyakeEvents—have now been identified as having occurred over the last 15,000 years. The most recent confirmed Miyake Events occurred in 993 AD and 774 AD. This newly-identified 14,300-year-old storm is, however, the largest that has ever been found—roughly twice the size of these two.

Radiocarbon traces left in tree rings by cosmic ray blasts are making it possible to date many historic events and ruins with remarkable accuracy.
