Extremely bright red light over Trowbridge

Hi. I just witnessed an extremely vivid red light in the night sky just before midnight 14/06/2014. It travelled about the same speed as a commercial aircraft for about a minute, then started to fade and disappear like a dying ember. There was no sound and no other lights visible as with an aircraft.
The light did not fall from the sky as it faded away. The shape was circular but not spinning or flashing on and off. Maybe a flare??? Have never seen anything like this before.
