A large solar prominence projecting at least 21 Earth diameters is seen in this H-alpha image. I imaged this prominence from my back yard this morning as the clouds were moving in. Each of the 21 blue dots represent the size of the earth. It was fantastic to see such a long prominence in this new solar cycle.
