Five orange objects "floating" over Colorado.A little after 11:00 P.M., as my family and I were heading in the house, I looked up to the west and observed five glowing orange objects moving slowly across the sky in a southerly direction.I quickly got the attention of my family members, and we were able to observe them for about a minute until they traveled out of sight.They made no noise at all. They traveled in a line, but the distance between them seemed to fluctuate, almost like birds. They did not move like normal aircraft, but appeared to be "floating." To me, they appeared circular. To my dad, they appeared triangular. Their color was beautiful.
