The sighting, reported anonymously, has been entered into the organization’s database.

The text of the report says, “On [495 North,] caught sight of two unusually bright lights as I was sitting in the front passenger seat on the ride home. Kept my eyes fixated on it and then saw a third light appear.”

The report continues, “[Three lights] then formed into one massive triangle, possibly mothership size. Couldn’t get a clear view because of the dark cloudy sky and trees as we kept driving. By then the lights seemed to dim out.”]
