Some people worry about the U.S. being attacked with an EMP (electro-magenetic pulse) which is supposed to be capable of destroying most modern day electronic devices, disrupt our power grid and disable autos with computer systems, etc.
Recently however, most have learned that we are already under attack by mother nature, specifically the sun. A sun solar flare was responsible for shutting down the U.S. power grid in the northeast a few years back.
Sunday, the sun started this week with a spectacular solar flare located at a sunspot known as AR2151. Although the place on the sun where AR2151 is located was not facing the earth at the time of the solar flare, the sunspot will be turning towards the earth this week and the forecast is for some spectacular solar activity.
