UFO Sighting in Madison, Wisconsin on 2017-06-03 20:30:00 - Very bright white light

My girlfriend and i were playing disk golf at hiestand park "hole 5" around 8:30pm on june 3rd 2017. i noticed a very bright light in the dusk sky to the south/south east about 30 degrees up and told her to look at it. she saw it right away and we both stood there and watched it. it was back dropped by the clouds as it was a warm and partly cloudy day, it looked like an airliner coming in for a landing with its landing headlights on or about 3-5 times the brightness of jupiter or the iss as it was such a bright ball of white light. it was in front of the clouds and appeared to not be moving much. we saw it for about 15 seconds and then it dimmed. i saw a small black dot as the light dimmed away, then the object completely vanished. within a couple minutes of me and my girl friend discussing the strange thing we just saw i pulled out my phone and googled flighttrader24 live flight radar to see if their were any flights at that position and direction and there didn't seem to be any...
