UFO Sighting in Forest Grove, Oregon on September 19th 2014 – Saw a bright orb in the sky split into a perfect traingle or three orbs then it kept splitting off into eventually 6 perfectly round orbs

I was driving in the plains of Forest Grove Oregon with a friend and about 8 pm on September 19th, 2014. All of the sudden my friend spots a big bright circular light in the sky, just stationary a little bit above the horizon. As we watch it, about one minute later it splits into three orbs, all the same size and shape. They make a triangle, one on bottom and the other two even split on top. Then it split from 4 circles to 5 circles to 6 circles in no uniform pattern, this happened over the course of about 4-5 minutes. Then the 6 orbs/circles stayed stationary in the air until we drove out of view about 5-8 minutes later.
