5 lights flying in formation at extreme speed.5 formation flying semi bright (three tims brighter than a normal star) lights were flying in formation from west to north. They seemed to fly in a formation like the number 5 in a dice. The "5 dice"-form was flying with the horisontal plane. The speed was really fast, but not as fast as shooting stars, rather a third of that normal shooting star speed maybe. The reason we saw it was that we were looking at the big dipper and pointing out were the exact north was so the both of us saw it extremely well.
