An unusual bright orange moving light in the sky over Plymouth UK.The night is cloudless. I looked out of the window to see a large orange light like a fireball in the sky, moving at what appeared to be the speed of a plane, over my house from west to east. The light was 2 or 3 times the size that the largest planet appears to be when it is close to the earth ie much bigger than a star and completely the wrong colour. It is difficult to estimate how high the object was, but it was possibly slightly over helicopter height, but there was absolutely no sound. I called my husband and together we watched the light move steadily across the sky. It appeared to get smaller and then possibly burn out. No other objects were seen in the sky, apart from a few stars, and neither of us have ever seen a light like that in the sky before. We are professionals in our 50s(a teacher and IT professional)and are not UFO watchers.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
