Four orange/red lights flying in formation one minute apart.

While walking my dog I saw an unusual very bright orange/red light approaching my location. It was moving west to east appeared to be at around 500 feet. I thought it might be a helicopter but as it got closer it was completely silent. It was moving slowly and appeared to be hexagon shaped. It was difficult to make out the shape as it was so bright. I watched it move off to the East never changing speed or direction. Having thought the show was over I saw this exact scenario three more times. They were roughly one minute apart. The last one changed direction from the others slightly and almost passed directly over my head.
