Crescent shaped object travels through night sky near Boulder.I was driving home from works when I saw an odd shape race across the sky. I had time to say, "Oh my God..." fairly calmly before it was gone. The shape was a bit of a crescent, at an angle to myself and my car. It was not moving towards me, and not heading at a steep angle towards the ground. It simply moved across the sky. There was a brighter light at the front, a dimmer one above and an even dimmer one below the brightest. They were the color of bright embers and did not flicker or blink. There was also no tale. The object seemed large, if I had looked at the end of my thumbnail and held it against the sky with my elbow a bit bent, it would have just covered the object.I'm not certain if this is related or not, but my cell-phone reception has been rubbish ever since even in places it was perfect before.
