These photos actually resulting from a coincidence.Searching the planet Venus I came to the idea to have a little view on the surface of the sun. And what a surprise, unusually large sunspots were able to be observed.By the way, at present time you can detect the sun marks with the naked eye. Wear protection glasses…!
