Bright orb of light changing to triangular shape and then back to orb shape.I live next to the fence line (border) of the Ravenna Arsenal in Charlestown Township, right outside of Ravenna. I have seen many military craft go in and out of the arsenal over the 20 years that we have lived here but I have never seen anything like this.I and a friend were out for our usual morning walk when suddenly my friend grabbed me and told me to look up into the sky. Just above the tree line there was a huge, and very bright, ball of white light that glided quickly across the sky in the direction of the arsenal. It was so bright that it was disturbing to me and I grabbed her in fear and shouted, "What the heck is that?"She explained that it caught her attention because it was so bright against the still dark sky and she first observed it as a ball of light which quickly changed into a triangle and then quickly changed back into a ball of light again. She said it reminded her of a holographic image the way it changed from one shape to another.It moved too fast to be an air craft and we wondered if it could have been a meteor although I have never seen a meteor that low to the tree line and that large. It frightened me. There was also no sound at all associated with this light. It passed right above us and then completely disappeared, like a light bulb turning off, within about 5 or 6 seconds.We live so close to the arsenal that when military craft fly in or out the sound is so loud that our home vibrates. We have been outside many times at night when planes have flown in and out and never have we witnessed anything like this. This was so out of the ordinary it was frightening to both of us.
