Was outside talking to neighbors when 2 lights that looked like stars appeared. One was north the other was south. Then their was a 3rd one that was blinking a white light. The 3rd light went to the light in the south. The 2 lights in the south started to hover next to each other flashing green,blue,and white lights. Then the light in yhe north dissapeared and then the 4 th light appeared with the other lights in the south.
