NASA: Earth Just Dodged Comms-Killing Solar Blast In 2012

The Doomsday scenario we should have been worrying about

A new analysis of data from NASA's Solar TErrestrial RElations Observatory (STEREO) by Chinese and Berkeley helioboffins shows that a July 2012 solar storm of unprecedented size would have wiped out global electronic systems if it had occurred just nine days earlier.

"Had it hit Earth, it probably would have been like the big one in 1859, but the effect today, with our modern technologies, would have been tremendous," said UC Berkeley research physicist Janet Luhmann.

The 1859 storm, also known as the Carrington Event, after the British astronomer who recorded it, swept over the Earth at the end of August and is the largest recorded solar storm in history. The aurora borealis extended as far south as Cuba and telegraph systems burnt out across Europe and the US, in some cases shocking operators and continuing to send signals even when switched off.
