When Space Weather Attacks Earth

Lasrick writes "Brad Plumer details the 1859 solar storm known as the Carrington Event. Pretty fascinating stuff: 'At the time, it was a dazzling display of nature. Yet if the same thing happened today, it would be an utter catastrophe...That's not a lurid sci-fi fantasy. It's a sober new assessment by Lloyd's of London, the world's oldest insurance market. The report notes that even a much smaller solar-induced geomagnetic storm in 1989 left 6 million people in Quebec without power for nine hours.'"
