Strange hovering light due East of Madison, SD. Sighting occurred at the dosc golf course at 7th and Blanche. Light hovered in the far distance and did not move. Light changed from red to white, back and forth. Noticed the light and took video. After video was take, a 2nd light appeared and went towards the light. It neared the first light and then veered away from it, out of sight. The light was still there at 23:45.
