I'd like to say to people stumbling across this thread and thinking "what's the aurora got to do with me" - you may be able to see if from your own locality!
In the UK:
Orkney and Shetland regions get regular aurora (but if you're there you probably know this...)
Northern Scotland gets aurora fairly often.
North Coast of Ireland, Anglesey, Northumberland etc quite a few times a year.
West coast of Ireland, North Norfolk a few times a year.
At least twice a year recently all the way down to the south coast (where it's dark enough)
So keep an eye out, and on this thread!
