UFO Sighting in Concord, North Carolina on June 22nd 2013 - Red light with blue aura around it. Hovered and moved left slowly and stopped before descending behind building.
I was working in a parking lot directing traffic and I looked up to see a objecting that I thought was a plane because of its red and blue light. I went back to directing and after an unknown amount of time I looked up to see it again but I thought it was a star. Then I realized the clouds in front of the moon. I looked at the object and saw it as a red light with a blue aura around it. I kept an eye on it for 10-20 minutes. I saw it move slowly to the left before stopping again. I then watched it slowly descend straight down behind a building. There was fireworks in the area which I think attracted it.
