Three large fireballs hover in place just north of Pueblo, COI was driving north 75mph on I-25 with 2 other passengers at 1:00am MST. We were almost halfway between Pueblo and Colorado Springs when we noticed two large bright orange fireballs, suspended in the sky about 400 feet above the ground and perhaps a mile or two away from us over the hills to the west. We agreed the must have been fairly large at their distance, each perhaps the size of a 2 story house. These fireballs appeared to be emitting smoke; we could see trails of smoke in the air lit up by the orange glow from the balls. We commented and started taking video, still driving (we never did pull over or break speed). After about 30 seconds, a third fireball appeared, as a tiny dot that cut slightly across the sky but grew in size to equal the other fireballs, over the course of 1-2 seconds. The three fireballs were, as far as we could tell, hovering in place in the air for 2-3 minutes, casting a glow on the hills nearby, burning bright orange and emitting smoke. They did not appear to move very much if at all as we drove past the event. We rounded a bend and lost sight of them behind a hill, and when we came to the other side a few moments later, they were gone. ** I will soon obtain the video my passenger took on his cell phone and post in on YouTube. I will title it "Fireballs north of Pueblo, August 23, 2014" **
