UFO in utah

I was riding through town the other day, on the way to my fathers burial site. and as i stopped and walked to his grave, i noticed in the distance, a hovering object. It was off in the distance, probably a few hundred feed away, just over the forest edge. It hovered there for about 5 mins, then just faded away. It didn't zoom off, of fly away, it faded. As if it wen invisible.

Has anyone ever heard of this, it really freaked me out. All i could think was that that space ship was watching my every move. I could visit my fathers grave long, i quickly walked back to my car and sped away.
