Over rush lake, outside of rush city MN I saw a football like shape comprised of solid red lights which, by there arrangement one could tell the object was a 3 dimensional oval prism that shined too bright to determine wether the object was transparent on the other side of the lights. On the left tenth or so of the foot ball shaped object was a difference in lights both color and texture-wise the surface of the object seemed to (uniformly) emit light and was akin to a police car's lights if there was no white strobe and also not flashing but only pulsating. This was distinguishable as the rear of the object because the direction of motion was towards the opposite side of the object. The object appeared to be at an altitude of 300 feet and noiselessly traveled east to west (ish) at a speed between 30 and 50 miles per hour before leaving my field of view, I know of two other witnesses who also witnessed this back in late summer 2015.
