I was outside talking with a friend and was looking up at the stars when I noticed a sort of dull bluish green object in the sky, seemingly lower than the stars heading from east to west. I think there may have been a very faint trail behind it but I'm not positive. For a split second I thought it might be a shooting star. We watched it heading in a straight path, going pretty fast until it was out of sight, which took about a minute. Just after it was out of sight another one came from the same place going the same direction, and we lost sight of it behind a tree. We waited for it to come out on the other side but it didn't. I felt excited, I've always wanted to see a UFO and I couldn't believe it. Shortly afterward at about 2:30 am we went outside for a cigarette and saw a third this time heading the same direction but coming from a different spot in the sky. We watched it until it went behind some dark clouds that we didn't notice at first since the sky is fairly clear tonight.
