Perfectly shaped triangle of stars, extremely fast moving, two stars circling each other.We saw a triangle of 3 stars (perfectly shaped triangle) that was stationary when we first noticed it. Within about 10 seconds, it started moving across the sky still in perfect triangle shape, then suddenly, two stars began circling each other very rapidly, while the triangle shape moved extremely fast across the sky until out of sight. There were 4 of us who witnessed this event and we were all stunned at what we saw.
