There's a chance that we might just get a decent aurora (Northern Lights) show tonight.
Big 'solar storm' on Sunday sent a lump of plasma heading our way and it should arrive tonight / early tomorrow. The more northerly you are, the better your chances but its worth sticking your head outside later tonight and having a look northwards anyway. (There was a display a few years ago that was visible in Spain!)
If its not cloudy I suspect.
