UFO Sighting in Florida on October 15th 2014 – 2 stop sign shaped groups of glowing orbs that changed into boomerang shape then disappeared. silent.

My husband was taking out the garbage when he saw 2 sets of glowing stop sign shaped orbs moving slowly and silently just above the treetops in a nw direction. He called me out to see. The orbs glowed from red to yellow to white then orange. The pattern then changed to a boomerang shape consisting of approx. 10 orbs. They glided along silently then disappeared behind the clouds. I told my mother about it the next day and she too saw them in the same direction. She had been over a mile away. These were not man made.
