I was out walking the dogs in the morning while it was still dark. when i saw what a first thought was a satellite moving across the sky. but after i while i saw another one right behind the first one flying in the same line. this kept going and it looked like a dotted string moving across the sky. there where like 30-40 lights following the same path with almost the same distance between everyone of them. they flew a bit faster than the airplanes in the sky at that moment. at one time it seemed the 2 last lights stopped for a moment before moving along. the lights was brighter than most of the stars. i dont know if satellites fly in in groups following the same path. but not according to a live satellite map. the distance between the lights is hard to tell. but if you hold a ruler in stretched arm in front of the sight it was about 10-15centimeter between the lights. the event lasted between 5 and 10 minutes before all of the lights was out of sight.
