Right as the sun set to the West, and the moon was shining bright to the ENE, an airplane flying upward in the Southeast sky was leaving a beautiful, colorful contrail. Usually a white streak against the sky, a contrail is a trail of condensed water from an aircraft or rocket at high altitude. It really was an awesome sight.
