I had just stepped outside and through my eclipsed sunglasses saw for the first time in my life with my naked eyes two sunspots on the Sun. The sunspot on the bottom right is 3780 and on the top left is 3784. Each sunspot could be six times bigger than Earth. SDO image is made smaller so it looks almost like by naked eye.
