the solar flair ups are a cause of concern for NASA and the Gov,, one strong enough could cause the electric grid to go down and knock out communication satellites, to go down as well,, and the "experts" say we are long over due for a really big one,,
but it is fascinating to see something so spectacular

Yeah, really amazing stuff.

As for the grid, I don't know if we've done anything to upgrade our grid to be able to handle such a flare (or even if there is anything that we can do about it).
