“The CME will likely trigger geomagnetic and solar radiation storms today, which could interfere with satellites in space and power grids on the ground, said Joseph Kunches, a space weather scientist at NOAA. Aircraft that fly over the Earth’s polar caps may potentially experience communications issues as well, and some commercial airliners have already taken precautionary steps, Kunches said.”
This is what people are talking about. The storm in question only glanced the earth and is causing issues. We are not prepared for a full blown blast to make contact with the earth.
