Bright Orange Object at 38000ft 200 miles SE of Nova Scotia, viewed for 15 Minutes.On the 6th of December 06 I was travelling on Continental flight C028 to London Gatwick from Newark NJ. It was 02:30 (London Time) and according to the in flight map provided by the airline we were apprx 200 miles SE from Halifax. We were at 38000 feet and travelling NE at apprx 548 MPH. The plane was a Boeing 757 and I was sitting in Row 15 seat F. I noticed a bright orange glow on a cloud which must have been at least 10 miles away. The sky was clear above the scattered cumulous which reached up to about 1000ft below our altitude. I do not remember seeing the moon. At first I thought it was just inner cloud lightning but thought this was odd because of the bright orange color. As I continued to watch I saw an intense bright orange sphere of light which was smaller than the size of a pea from that distance. The sphere hung in the air and did not climb or decend and remained at about 10 miles. The object lit up the cloud behind it with a bright orange glow similer to athe glow achieved by a fireplace. It was orange. The object remained very bright. Almost laser bright. I spoke to the lady sitting next to me in seat 15D and asked her if she could see the same thing. She agreed. She could not guess what it could be. We both watched as the object remained and we moved Eastward. We watched for at least 5 to 7 minutes. The object then started to desend through the cloud causing the glow to follow down against the clouds behind it. The object desended vertically through the clouds. After about another 4 minutes we lost site of the object but the glow took longer to disappear. I did consider that I had witnessed an inflight collision but on landing in London there were no reports of air accidents.
