in Visina, Dambovita, Romania, captured giant sunspot AR2786 on November 24, 2020. In this image, the sunspot is the large dark region in nearly the 9 o'clock position on the sun, near the edge or "limb" of the sun. A small dark spot - called AR2785 - is immediately to its right. Thank you, Aurelian.
