Remember that post where I said we should expect more frequent Coronal Mass Ejections (CMEs) around 2012?

One such CME hit the earth earlier today causing auroras in many states in America. (Auroras usually occur near the Arctic circle.) It wasn’t strong enough to cause any damage; just strong enough for some gorgeous pictures. Details and pictures here.

Cosmic events have unparalleled beauty. It’s a pity most of them would kill the human race if they occurred any closer.
