I was out on my front porch having a smoke when i saw in the northern sky 2 rings alternating orange and yellow in color, dimming and brightening as they moved across the sky. the objects seemed to be orbiting a mutual center of gravity. the rings appeared out if the trees low in the northern sky, and wobbled their way heading nne. my sighting ended when the objects went being some thick trees from my point of view. i was able to view the objects for 2 minutes. this is my third ufo sighting.
