Camping in Lolo forest Montana with friend we were looking at the stars and watching shooting stars when we saw the object which we first thought was a very large satellite, we both had a strange feeling about it as it flew straight across the sky above us it was moving at a steady pace and looked like a big bright star or satellite we began shining our bright flashlight at it yelling for a few seconds when it flew to the other side of the horizon, it started to dim and shimmy back and forth going in an upward direction faster and dimmer until it disappeared. Neither of us had ever seen anything like it before.
