The sprawling archipelago of active region 1520... this field of view spans more than 200,000 miles on the surface of the sun! Here is a close-up of the central region. This image was featured on and Phil Plait's blog on Discover. The view in Ha light is quite a different story. And while these spots stole all the attention, a lovely group of prominences was dancing at the edge of the sun.
