V-shaped light formation over Beachwood, OHI was walking across the parking lot at the JCC in Beachwood to play volleyball. It was a very clear night. I was watching a small airplane’s lights traveling due west, when I noticed a V-shaped series of white lights above it, moving in the opposite direction (East). It looked like a boomerang formation of 7 or 9 round lights. It was higher and less clear than the plane and had a halo around it, as if it was in some thin clouds (perhaps it was). The V was moving much faster than the airplane - maybe 5 times faster (not accounting for differences in distance from me). Shortly after I caught sight of it, the V turned right (south). It did so abruptly and without much of a curve through the turn. When it changed direction, several of the lights seemed to rearrange themselves - as though they were discreet objects in a formation, not fixed to one single object. They did so very quickly - spontaneously - to go from a eastbound V to a southbound V. The wedge flew south into a part of the sky that was bright from city lights, and I lost it. It made no sound I could hear, and no one was with me when I saw it. The whole event lasted 20 to 30 seconds at most. I have no idea what it could have been.
