The Carrington CME event happened back in 1859 and there is evidence that such an event happens around every 150 years. 1959 would be 100 years and then add 50 more years and you'll get 2009. We are ten years past the average time for another CME event. The difference is that we now have our homes connected to many miles of conductors. I expect that it may be wise to have a few fire extinguishers handy. I have seven large ones standing all around the house. We may receive a warning of around 24 to 48 hours? Now try to think of what life would be like after another CME and plan ahead by reading books like: Lights Out, One Second After, and the fifteen books written by, Joe Nobody called: Holding their own.
