Thanks for posting. I was living in the Caribbean when that happened, and there were no news reports about it locally.Satellite or power grids disruptions depend on the intensity of the flare, of course. This is an X1.1 at the moment. An X28 in November 2003 caused disruptions in satellite communications and power grids. A similar storm in 1989 knocked out Quebec's power grid.
