Power outage warning: "Big solar flare heading to Earth" — time of "direct hit" predicted
Forecasters at the Space Weather Prediction Center (SWPC), a unit of the US Department of Commerce under NOAA, has issued a G2 geomagnetic storm warning for October 11. Solar storms are rated on a scale from G1 to G5 – with one being the weakest and five having the most potential for damage.
