Boomerang With floating/fluttery material.On November 19, 2016, at 23:00, I looked up to my right and noted this huge object that was soft light color/glowing softly, noticeable,come across the 10th hole fairway of Prairie Green Golf course from west to east. Noted there seemed to be like material on object, that was like fluttering like a flag in the air but again, no sound at all. Complete silence as it continued moving in easterly direction. Huge.
