Remarks
I was on my way to work and first saw a red light in the sky. It caught my attention because there are rarely aircraft visible that time of the morning. I continue to watch it when all of a sudden I saw what would be described as a vapor trail commonly seen during daylight hours behind aircraft. It was a red orange color. After about 15 to 20 seconds, it disappeared.
