In reply to sbc_10:
I don't think I've seen them before, despite keeping an eye open for such things. If I have, it has been glimpses of much less impressive displays than these ones.
Scotland will doubtless get them more often than England, being further North and having more hills, but I think they're still pretty rare here. And I imagine they're often hidden above other cloud layers when we do get them, too.
I wonder whether we'll see more this evening? The main storm has passed, but it still looks like it'll be quite windy, with broken cloud. Less likely, but probably still worth checking, I think.
Oh - we might have to slop on the sun cream now, apparently:
