Out walking dog. heard plane. looked up. saw the plane then noticed this other object. it was high in the sky - was a clear sky. it was moving south to north at a faster speed than the airplane. it had no flashing lights. was solid. bright white. then it shot off due west really fast. there was a change in the atmosphere - like a kind of time shifting feeling. a wierd woosh like it was warping. no sound. couldn't be sure but i think there was a flash/beam as well.
