Two large UFO orange spotted near Denver

On November 11, 2014, a man and his wife drove on a road in Centennial (South of Denver, Colorado) when they saw two large objects glowing orange. She tried to take a photo and, on it, we can see a mysterious green UFO.

Witness statement:

My wife and I were driving South on I-25 from Denver to Lone Tree, CO. I noticed two circular, large objects at very high altitude. They appeared to be moving slowly East. I asked my wife to take photos of the objects, but not through the windshield. She used her iPhone 5S to take several (6-10) photos holding the phone outside of the passenger window facing the phone South. Unfortunately, she deleted most of them after we got home because they were not good shots of the sky (she thought I wanted pictures of the "pretty" clouds). The one remaining shot did not reveal the orange objects that I saw, but a greenish object in the upper right portion of the photo.
