Massive double Sunspot 1263 – wider than the Earth – harbors energy for powerful X-class solar flares!
Double sunspot 1263 is a whopper. Its two dark cores are each wider than Earth, and the entire region stretches more than 65,000 km from end to end.
The clarity of image is impressive. Note the granulation of the stellar surface surrounding the main dark cores. Those are Texas-sized bubbles of plasma rising and falling like water boiling on top of a hot stove.
The magnetic field of sunspot 1263 harbors energy for powerful X-class solar flares. Because the sunspot is turning to face Earth, any such eruptions in the days ahead would likely be geo-effective. (SpaceWeather)
