I was heading home with colleagues in the car when I noticed a strange horse shoe like shape in the sky with green and red lights, we stopped the car and defendant it still didn't move and had a a very low light in the middle 5hat switched on and off it was fixed for 10min and the it started moving and twisting and I could see the round full shape then it flew to the opposite direction and lowered and I lost site.
