For them that's interested, I've received an amber alert from Aurorawatch. This normally means a fairly good chance of an ok display of northern lights, possibly visible as far south as Newcastle.
Feel free to wave your willy about your own lights, how much better the light pollution is in London, point out that your BMW is the ideal car from which to watch the night sky, ask which tyres are best suited to not looking where you're going, post the daily mash's response, etc, etc
