A stationary red light accerated incredibly fast and changed to orange color and traveled away at a high rate of speedMy wife and I were driving North on U.S.Highway 53 about one mile from Cotton,MN, when we noticed an unfamiliar stationary red light near a radio communications tower which is about one quarter mile from the highway. We slowed down and then stopped along side the highway about one half mile after initally spotting the light to get a better look. The light was a steady red color like the top light on the communications tower except there were fainter secondary lights. The unknown light was somewhat further from the highway and appeared to be about twice as big. Upon stopping and watching for a few seconds the object accelerated incredibly fast to the South at very high rate of speed changing from a steady red to a blinking orange light with dimmer secondary lights of red and white. The object traveled a distance of two or three miles in a matter of a few seconds and shortly after disappeared from sight.
