UFO Sighting in Gatlinburg, Tennessee on July 6th 2015 – oval shape. red and green lighting. reflecting of the sun right above horizon line

I decided to take a picture of the beautiful mountains. I didnt notice this object until i developed my pictures. I saw a black dot in the sky and as I got a closer look in graphics I noticed a ufo of some sort. it had red and green lighting around it. I am sure it is not an airplane or anything so i am very concerned if i can get an explanation
