Walking dog, Looked up and noticed normal plane flying in westwardly direction. Suddenly out of nowhere it was as if a star had dropped from the sky and was Very low overhead. Within Bow and Arrow shot distance. It was about the size of a basketball and looked just like a star or planet and moved over from my west to the east directly above me. I was stunned, as I watched it for 30 seconds approximately and then suddenly vanish while still in plain view. Didn't shoot off or fly fast just moved totally silently and smoothly and vanished as if it were turned off. Went inside, grabbed a cigarette went back outside at approximately six forty two and for the next twenty minutes six or seven planes flew in the exact path that I had seen the object, circled and flew again. Planes have continued flying overhead and it is nearly eight O clock. This was NOT a plane. One Huge Starlike light. Starlike is the best way i can describe it. It was phenomenal. Totally rattled me. I'm still pumping with adrenaline.
