I was repairing the window on my dump truck and caught the object as it appeared over the pine tree in my back yard. Looking as if it were over our pasture, it made a curve upwards then came down between the pine and cedar and disappeared into thin air. I first noticed the object because it was in my line of sight as I tried to line the mirror up before the glue dried. It was directly in my line of sight behind the mirror I was working on. I thought it was a falling star but I noticed the "tail" was not normal and that the entire object was the same amazing color that I've never seen before in the sky. It just appeared in my viewing window as I looked at the mirror, then I watched it make a sort of half loop up and then down, and disappear into thin air. I was completely amazed and in disbelief. I don't believe in UFO's. I really don't!! I still don't, until I find out for sure what this was anyway, my wife looked all over the internet to find something or someone who had something in the sky this morning, and found nothing so we decided to speak to you. The object just disappeared as easily as it appeared but after it made the half moon shaped path from mid sky upward then down, then disappeared.
