Looking at the moon outside for a moment, noticed this odd formation of lights, they were stationary and together form a really large right sided triangle. Maybe if it's a craft it's sort of invisible? The first night I saw it, on the 11th, a helicopter was flying not far from it, and about the same altitude. Which seems to be several hundred feet above the city. I have seen it last night too, but it seems to be a little more west.
