About 10pm one night as I was sitting at the back porch I glanced up to see a round black disc surrounded by a halo or aura silently flying across my line of vision. It took only a few seconds before I lost sight of it. I'll never forget it as I know it was no plane, blimp or any other air craft I've seen before. The height of the object was above tree level how high I couldn't tell you, but I do know it wasn't any star, planet etc. either.((NUFORC Note: Date is approximate. PD))
