round object with single red light in center.We were outside on the beach looking at the stars when we saw the object. It looked like a round, flat metal brown-beige object with a single red light in the center. The object was the size of my thumbnail at arms-length away from me. It moved across the sky silently in a straight line then seemed to disappear, though I may have just lost sight of it behind trees or something. I thought we watched it for 20 seconds, but my husband believes it was only 5-10 seconds.
