HUGE Sunspot AR2443 hides spaceship

Sunspot AR2443 is so big, it is attracting the attention of astrophotographers around the world. Earlier today when Peter Rosén of Stockholm, Sweden, photographed the sprawling complex, he found a spaceship hiding among its dark cores. Seriously. Take a close look at the image below:
Indeed, AR244 is huge. From end to end it measures almost 200,000 km. Many of the dark cores are as large as terrestrial continents--and a couple are as large as Earth itself. These dimensions make it an easy target for backyard solar telecopes.
Of greater interest is the sunspot's potential for explosive activity. The spotty complex has a 'beta-gamma' magnetic field that harbors energy for strong M-class solar flares. Any such explosions will be geoeffective as the sunspot turns squarely toward Earth in the days ahead.
