Astroboffins are warning that a mighty "eruption" of superhot plasma has been blasted out of the Sun directly at the Earth. The plasma cloud is expected to reach Earth beginning tomorrow, possibly causing strange phenomena - including a mighty geomagnetic storm which could see the Northern Lights aurorae extend as far south as Blighty or the northern USA.
That's pretty much a summary, go to the article for the rest.
If you're lucky enough to live in the northern USA/Canada or northern Europe/Asia, you might be able to see the Aurora Borealis! I wish the article would give us an exact hour...
I live in Southern Pennsylvania, I'm not sure if I'll be lucky enough...
Not sure if I'll be able to see it, but I'm considering getting out my AM/FM/shortwave radio to try to pull in distant FM radio stations (I've actually gotten stations from Baltimore, Philadelphia and even Detroit that way sometime last year, all from the Albany area). =D
