It seems that it can be a real danger of power grids gowing down.
I just received a call from Bill Murtagh who is the top forecaster for the Space Weather Center in Boulder, Colorado. He told me the Kp index has gone off the charts and all SWC personnel has been called in. There is a great concern of a second CME heading towards Earth. There is a real and present danger of power grids going down.
