Tucson - Lights in the sky on Thanksgiving night spark stories of possible UFO's or comets flying over the desert.

People living in the area of Houghton and Golf Links report seeing "fireball-like" lights shooting through the southwestern sky Thursday night. Some thought the lights could be the comet Ison, which is heading toward the sun.

News 4 viewer Jeffrey Compton sent in video he shot near his home showing the fireballs glowing in the night sky.

So far, no official explanation for the glowing lights.
