Can I just say about the end of September time here in the UK - Sheffield, South Yorkshire.
I saw flashing lights above the clouds - no thunder, no rain so it wasnt lightening. These flashes were above the cloud layer and were big (too big to be fireworks) and they were of a white colour!
Anyone experienced this before? I thought it could be the Northern lights, but: A: they occur in the winter months and B: we are too far south.
