Bright white circle left light streak, faster than any jet

Bright white circle appeared in NE and instantly shot NW, it was between Cesna and commercial flight height, maybe 10000-15000ft and size of quarter in my finger measurement, distance covered was about 4 inches in tenths of a second. It left a perfect white light trail its whole distance that all disappeared at the exact same time as the ufo. The streak was so defined and clear I could see windsheer around the object seperating the light from the object. There was no sound and this was not a exhaust trail like a plane, it was just bright white light.
