Black Triangle Sighting in Mankato, Minnesota on May 30th 2015 – Small orb like triangle, with orange lit lighting (no sound)

I was on my way towards Mankato (SW of Eagle Lake on MN HWY 14) when I saw an orange lit orb triangle shaped object about 50 to 70 ft hovering above local radio station (MN 93 Country Radio Station between Mankato & Eagle Lake near roundabout on 14. I pulled over to the side of the road to try and take a photo but by the time I had gotten out of my vehicle the object was gone.
