This is from NASA latest solar image “movies” available here. This shows a 48 hour time lapse of the surface of the sun, 15 October to 17 October 2018. The surface of the sun is currently “spotless” in that there are no “sunspots.” But as you can see, it is hardly featureless; in fact a coronal hole pointed our way may cause visible aurora if you live in a dark place close enough to the poles.
