I just saw a light in the sky that I can't explain, and I was wondering if you could help at all. At approx 11:30 pm (British summer time) I noticed what seemed to be a very bright star in the west, reasonably low in the sky (perhaps 30-40 degrees from the horizon). The light grew for a few seconds, becoming brighter and larger than any star I've ever seen, before diminishing into what looked like an ordinary star, and then nothing. The whole thing took no more than 10 seconds. It was too bright to be an aircraft, and lacked the sweping motion of the police helicopter's searchlight, plus i was unable to see any flashing aircraft lights afterwards. Can anyone suggest what I might have seen?
