Coming from Grand Forks going west on highway 15. We were looking at Christmas lights when we noticed 5 white lights to the south of us in a circular position.These lights were big not like an airplanes.They flashed one at a time, when the last one came on the others disapeared.Then the lights disappeared.This was a moonless night and we didn't see what shape the object was that the lights came from.So as the lights dissapeared we looked for a sign to let us know our location and it said Aneta 3 miles.That's it.
