It looks like the sun has developed rash. Sunspot group 1105 consists of more than 25 tiny spots scattered across an area some 40,000 km wide. Sascha Somodji sends this picture of the busy active region from his backyard observatory in Krefeld, Germany:
Sunspot group 1105 stands in marked contrast to nearby sunspot 1101, which consists of a single dark core. (Click here to see the two side by side.) If sunspot 1101 looks boring, that's because it is. The sunspot's magnetic underpinnings resemble a simple dipole, and the spot is correspondingly quiet. Sunspot group 1105, on the other hand, is much more complicated with a profusion of opposite magnetic polarities popping up and bumping together. Magnetic reconnection is happening there almost non-stop, causing sunspot 1105 to crackle with B-class solar flares. It is, indeed, a "rash sunspot."
