UFO Sighting in Bruneau, Idaho on July 18th 2015 – Solid light, size of star, no sound, extreme speed east to west.

We were at the Bruneau Sand Dunes observatory when we saw a bright light, the size of a star, it seemed very high and it was moving faster than anything else I had seen. I have seen satellites at night before and this was brighter and much faster. Also witnessed by my stepson. There was no sound. As it moved closer west it disappeared. The skies were clear. There were many stars in the sky.
