groups of black circular objectsIt was a little before sunset when I was out on the balcony looking out towards the west. I notice these black things up in the sky and thought (at first) they were geese flying. Someone that was with me said, "No, those aren't geese." So I looked harder and noticed there were more of them. The first bunch I saw was 5, black, circular objets, to their diagnal was 4 more, then 3, then 2, then 1. They all seemed to be hovering in place. After about ten minutes the first five started moving. Then the other groups followed. They moved west then disappered.
