Yellow ball of flame traveling through the sky.We were in the front yard when the wife and I saw a large round yellow ball of flame going from the South East to the North West. There is a layer of clouds out and it was below this level. There was no sound to it, just the large round ball of yellow.It lasted a good 90 seconds to 2 minutes, as it traveled North, it got brighter until it went behind the houses and we could not see it any more.
