Giant Sunspot Region AR 2529 17-4-16

The Sun’s activity is now heading towards solar minimum, but it can still occasionally surprise us with some large surface features such as sunspot active region AR 2529 which appeared over the last weekend. To give you some idea of scale you could fit five Earth’s inside the dark area of that sunspot ! It is so large people have reported seeing it at sunset behind thin cloud with the naked eye.
