UFO Sighting in East Carbon, Utah on June 20th 2015 – Standing on my porch, 6 spheres, 3 large and 3 smaller ones traveling southeast over East Carbon, then all 6 disappears

I had just walked out onto my front porch, trying to cool off from the hot temperature inside my house, and standing where the driveway meets the porch, I noticed 6 spheres or orb like objects traveling from the northwest, headed somewhat towards the Book Cliffs. When they got over East Carbon, they just blinked out, like as if someone was turning off a light switch. There were 3 large white translucent looking or somewhat glowing spheres in a row, with 3 much smaller ones following them from below, in a triangular formation. I have seen small planes and helicopters fly over this area many times and these 6 objects was traveling much faster than any plane or helicopter that I have seen. These spheres or orbs looked very solid and traveled in a straight line, nor did they pulsate or change direction. I have seen these spheres many times before in the past and thought it would be a good idea to start reporting them.
