Started of the NLC's were spotted around 12am as a very high cirrus like formation. As it slowly darkened the extent of the display became visible. It lost its height but was very wide stretching from the nw to ne.
What a fantastic and impressive display - the best of the few I've seen. Only really saw it between 3 and 4 am when there were decent gaps in the cloud. Never expected NLC to be that extensive in terms of sky coverage down here in Hampshire.
