I was in my house looking south with my patio door open. A bright white round object came into view in the upper southeast portion of the sky. It was traveling fast without a vapor trail at a speed I haven’t seen with a plane or jet. I live by a naval air station and see navy jets all the time. The object traveled down to the lower southwest portion of the sky before it disappeared behind the tree line. I’m thinking it might have been the international space station passing over, which I’ve also seen before at night. This object seemed larger which may have been from the sun hitting it since it was a very clear sky.
