it looked like a very fast moving tiny star very high , very high. it did not leave a trail of light it did not land or fade.We observed 6 small lights with a two hour pereiod. the First two lights were travelling in a circular motion and they eventually met each other and kept going in a large circle above our heads. They were extremely high in the air. They were as high as any star. They were visibally higher than any visible satellite. then later another light flwe in a straight line from south to north. Then later on another from north to south. then we saw 2 more a different time one more circling and then the last travelling in a straight line from east to west. This was not the first time we have seen them. We have seen them in summers past while we are sitting out looknig at the stars. I an very curious to find out what these fast moving "stars" are.
