No, sadly, those aren't aliens. Instead, the unusual lights over the Whitefish Bay in Lake Superior, were light pillars, which were caused by falling ice crystals.
I was looking for auroras but was pleasantly surprised to see light pillars early Tuesday morning, October 16th. This is a shot north of Paradise, MI looking east over Whitefish Bay. The red lights are around the Canadian island Ile Parisienne and wind turbines.
