There was a news report tonight suggesting we might be in for a major cosmic flare which would crisp our electronics and satellites. Does anyone know how fast a flare goes from sun to earth. A friend said we should turn of our electronics, and possibly even throw the main circuit breaker for the house. Any opinions/knowledge? They also spoke of something called the Carrington Event in the 1850s which fried American and European telegraph systems.
