Was out on my back patio with friends when we noticed a bright object flashing lights and moving slowly accross the sky, almost directly above us. It was daytime so we assumed it was balloons reflecting light from the sun. But the lights were intensely bright, red, green and white, so we thought it could be a blimp or drone. So I grab my binoculars for a closer look. I was so impressed with what I saw, it was incredible! A donut shaped object. Clearly a donut. It was rotating, spinning, flashing its lights on the outer edge as well as inside the shape. I could clearly see through the center of the object. It was charcoal colored. And the lights, and movement were impressive. Watched it rotate and flash until it was lost behind other buildings. Incredible.
