Bright white light in night sky flashed, moved to the right, then faded out.We was with a group of four people. We were in our backyard in Silverton, Oregon. We were camping outside at around 11:00 pm looking up at the stars, when suddenly, there was a really really bright light that at first we thought was a star. It was the same size and color as a star but it was super bright. We thought it might be a planet but we used an iPhone app to look at the planets and the light didn't show up on the app even though a star right next to it, called Deneb, did. All of a sudden, the light flashed. We watched it start to move to the right but suddenly the light faded into the dark night sky. We waited for it to come back but it never returned.
