UFO Sighting in Yellowknife, Northwest Territorie on September 28th 2014 – Disc Glowing Object

Was taking picture of beautiful evening sky and formation of the sky that evening, didn't notice until I started viewing the pictures and notice bright object and I took forth different shots that evening so 2 mins each time and notice the object still hovering and gone on the forth pic. I believe in UFO because this might of been the second time.
