Details:
It´s a dark monster in the Sun´s surface: AR4366 is one of the 10 or 20 largest sunspots I have seen in over 30 years of solar observation.
I took this image this morning (10 am local time) in Buenos Aires, with my 120 mm refractor telescope, solar filter and Canon T7i camera.
It is the result of stacking and processing 25 shots, selected from 107.
