Galaxy traffic beacon on the north pole of the Sun, UFO near the sun - Nasa STEREO

When you see this video - you would have impression, that strange object on the north pole is moving. But it is not correct. Don`t forget that BEHIND (NASA) is moving around the Sun by Earth orbit. Full turn around the sun takes one year. Now take a look at timestamps on the video: one oscillation period of object takes one year. So what does it mean? It means three things: 1) Object on video behaves itself, as sunstationary satellite over the geometrical North Pole, it prolongates Sun axis rotation. 2) Centrifugal force of the sun rotation is absent on the pole. So to keep its position above the sun - object must have engines, that will hold it from falling to the Sun! 3) It`s not technical bug of the satellite or its optics - in this case this point would always appear at the same place of all photos. What would it be? It seems to me like some highly developed civilization artifact that can act in Solar atmosphere (its temperature is about 1 500 000 degrees Celsius) PhotosGalaxy traffic beacon on the north pole of the Sun, UFO near the sun - NASA STEREO
