Well the whole area is a hotspot.
I remember, just about...I was a nipper...maybe 12/13? I attended an event with my older brother in Warminster...some sort of conference...it may well have even be an early Fortean Times event?
Anyway - we went for a "UFO Hunt" with some guy on Cley Hill in the night. I think he was an FT contributor. It was fairly uneventful. Except for, at some point, the whole area was lit up with a greenish, strobe-light/lightning effect. It was very powerful, lit up the whole area and beyond. Hung there for longer than a strobe light, maybe a couple of seconds, then darkness returned. Very odd.
I was very young. Interestingly my brother remembers it, but remebers the "flash" being blue.
Hi, the South West of England of England is occasionally treated to aurora borealis (Northern lights). For example:

"Brian Sheen, from the Roseland Observatory in Cornwall, said the Northern Lights could be seen around once a year in Cornwall but were rarely noticed or captured.
"We don't get it so brilliantly down here as they do in the north. I've only see it three or four times in my life", he said.
Mr Sheen said the display was caused by a burst of gases kicked out from sun spots that interact with the Earth's magnetic field and hit the atmosphere creating "these lovely colours".
Dr Chris Arridge, of Lancaster University Physics Department, said: "If there is greater solar activity, they can, on rare occasions, be seen further south, if the conditions are favourable."
The Met Office, based in Exeter, said on its
blog that the country could have another night of "spectacular aurora views" on Wednesday.
"To see the northern lights, wait until at least half an hour after sunset, go outside away from artificial lights, let your eyes accustom to the dark and look towards the north," the Met Office said."
In 1979 my brother was in back garden in North Devon when he witnessed the night sky turn green in the early evening of a winter night, which properly peed me off as I had just gone in to get a warm coat...! He said there was a wavy effect and it later made the local papers that many others had witnessed it locally.
