Details:
Active Region #12833 is the only spot on the sun. A close-up image shows #12833 a nice looking asymmetrical sunspot and it is surrounding by granulation. Working with the contrast, the umbra has some brightening and this depends on the strength of the magnetic field. Also, a close-up of the granulation. Some of them have irregularly shaped cells and they are separated by dark lanes.
