I also saw a moving light about that time (also from Washington State) which I took to be a satellite. It was a bit different from other satellites I've seen in that it was very bright when I first saw it, so I thought it was a planet. Then it dimmed and as I realized it was moving it disappeared.

But now that I think about it, the one I saw moved from North to South so it wasn't the same. I suspect a lot of people may have seen things in the sky they aren't used to just because they don't usually look at the sky.
