Remote possibility of aurora visible from lower latitudes.
Thanks Mike,
I'll monitor SpaceWeather if a possible sighting is likely I'll head out somewhere with a very dark view to the north - possible N. Kent somewhere.

I've just realised that even if there is no cloud (unlikely) there is too much moon :(
