What is this 'spot' on the sun?

These images come from someone I trust. This person accurately predicts huge storms, earthquakes, and stellar events. He posted these pictures.

I will not speculate as to what this spot on the right side of the sun is. I'm not into 'conspiracies' (although quite a few appear to be true).

I'd like the communities' help figuring out what the "spot" is. All ideas are welcome!
