UFO Maybe?

I always take a flashlight when I go out with the dogs every morning. This morning I shined all around the yard and for no reason shine a star in the sky. Something happened that has really confused me. If you look from the left of the light in the sky you will see a white object come from left to right and disappear. It's very fast and seems to come from behind the light and circle around going off to the right. Any ideas what it could be?
