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.
