UFO Sighting in Loveland, Colorado on June 3rd 2015 – two bright green lights accompanied by bright red light in heavy thunderstorm

I was watching an intense lightning show out of my second story bedroom window about 9:30 pm. I suddenly noticed two green lights to the north, right in the middle of the thunderstorm, and thought it crazy that either a plane or chopper would be flying right through it. I thought it to be an airplane at first, but then noticed no red navigation light, nor any strobe collision light, only two green lights. I got my binoculars and then was able to define two bright green solid lights right next to each other horizontally in a fixed position about 45 degrees in the northern sky. Lightning was exploding all around them, and when the sky lit up from the bolts, I was able to see how big and bright they really were - way bigger and brighter than aircraft nav lights. The two lights stayed in a fixed position for about 15 minutes, right in the middle of the lightning storm. Then suddenly, a third bright red light appeared below the two green lights, making a triangle. Then after about 1 minute all three lights descended quickly below the tree line and disappeared from view. The rate that the lights descended was way faster than a chopper could drop from that elevation. My wife and I took several photos on our smart phones, but unfortunately the images had poor resolution (no surprise.)
