Object was first observed after blinking once up in the sky then it proceeded to move directly overhead of us at approximately 100-200 feet above in a straight line. It stayed a constant yellowish wite color as it went overhead. Our dog had been laying calmly outside and immediately got up and started barking and barking and wanted to go inside. My husband let her out of her lot and she went immediately to the door to go inside like she was upset and scared and wanted to get inside the house. He took 3 photos with his cell phone as it went above us. As it was above us he said he could tell it had depth to it. It then flashed 2 to 3 times and was green in color and then it completely disappeared. Right after this happened we saw 3 planes flying closely together in a straight line flying east to west. The object flew from NW to SE on a 140 degree bearing. We could tell these were planes because they were higher in the sky and were blinking in white and red. We have seen planes many times before in the sky at night above our house. This all happened around 9:30 pm and lasted for 4-5 mins. The object made no sound whatsoever.
