Large and unusual light observed in the evening sky just southwest of Frisco, Texas...I was headed south on Preston Road, about 2 and a half miles north of Frisco, Texas when I observed a bright light in the sky, southwest of Frisco, Texas, with a cloud as a backdrop. The light was white gold in color, and looked to be at two levels, top and bottom. It was dusk, but the Sun was still low on the horizon, and thought at first the light might be a reflection of the Sun on an aircraft approaching DFW Airport, which is relatively nearby.I became convinced that the light was not an aircraft or helicopter. It seemed much too big, like a sudden star in the sky. Besides, living where I do on the north side of the Metroplex, I see airplanes and helicopters flying overhead all of the time. I know them by sight, but what I saw this evening didn't resemble a plane or copter at all.The light stayed in one place, backed by the cloud, for almost two minutes, then rose above the cloud, in a straight line and much faster than a plane or copter could, for about five seconds. The light then completely disappeared, in the blink of an eye. The Sun was still visible, so if what I saw was some kind of reflection off of the sun, it would NOT have disappeared as it did.I looked in all directions from the light, for several minutes, but I did not see the light any further after it disappeared.
