I was in my car at a local business waiting for the replenishing crew. Looking at the stars I noticed what looked like a satellite moving across the dark sky, when it began to fade out. Thinking it was going in to the earths shadow I looked away and noticed a shadow moving across the sky. The object is hard to describe. Imagine a brick with rounded edges and protrusions sticking out on both ends. It was a little darker than the sky. It glided over the top of the building and disappeared. If you followed the angle back to where I saw the light dim out, it matched. I told my co workers what I had seen and was thinking about reporting this, but decided not to. Two days later which was today, a co worker told me about a radio program she was listening to that described an object, like the one that I had seen.
