Shiny UFO caught over Cheektowaga, NY

On August 22, 2015, a man has seen a very amazing shiny object flying over Cheektowaga (State of New York) before photographed it. What is it ?

Witness statement:

Shiny object caught my eye and I took a zoomed picture. Never seen anything like it before. Spotted it above KBUF. It doesn't like a weather balloon as I have seen many launched from the NWS at KBUF often. If you have any Idea what it is let me know.
