A mate of mine saw them in Aviemore this year when she walked back to the house while the rest of us were getting lashed in some club. I think they were visible for 2 nights there, but there was a particularly strong solar flare that made them visible so far south of the Arctic Circle over those 2 nights.
There's a bit of a myth that it has to be cold to see them too, but the solar winds are hitting the Earth constantly and it's just a case of being in one of the right places at the right time and you might well have seen them Brock if the solar flare was massive beforehand, like the time one wiped out many orbiting satellites and took out a good chunk of North America's power grid. Rare events, but they do happen.
