Triangle over River Falls/Prescott, WI

The report, as filed

I was sitting on my deck and leaned my head back to stretch and noticed a bright light in the sky. I couldn't figure out what it was so I kept watching it. It was a clear, blue-sky day with no clouds. The object was very bright and the lights were sort of on the sides. It was like reflective lights that were flashing very quickly. The object had a triangular shape and was gray in the center in between the lights. The object was stationary and then quickly shot off to the side and disappeared. A few seconds later the object appeared again in a different spot along with more similar objects. At one point several of the lights/objects went into a circle shape and then zoomed off and disappeared. The objects kept appearing, veering off VERY fast and then reappearing smaller, which just seemed farther away. I took a video the last minute, or so. Another person saw the lights toward the end, when they were smaller and farther away. My dog started barking! ferociously when the original object veered away rapidly. These objects were also moving around the sky erratically, quickly changing direction or disappearing and reappearing.
