NASA Sees Monster Sunspot Growing Fast, Solar Storms Possible

A recent quick-look intensity image is here:

The sunspot group referred to in the article is near the right-hand edge in this 4Kx4K pixel image.

If you zoom to the full-resolution of the image, you can see curved features in the space between the two large sunspots that trace some of the magnetic fields referred to in the article. When these field lines become tangled, they store energy, which can be released suddenly if the field is reconfigured.

Our planet would fit easily inside either of these two sunspots.
