Blue light with absolute definition seen over Seymour

On this night I was out on my back deck having an evening cigarette. I was stargazing as I often do and was looking straight up at the constellation Cignus when I saw a very bright bluish light. It was about the size of 4 average stars clumped together as seen from the earths surface. It appeared in one place then disappeared then the same light appeared about 2 degrees to the east. I was facing north. If it was the same object it was moving extremely fast. Much faster than a meteor entering the earths atmosphere. Then it was gone. The night was clear , about 50* with no wind. What I saw was there and was not a reflection or a plane or helicopter. I live under a flight path and see aircraft all day. This, if it was a craft, is something I’ve never seen.
