The Largest Sunspot in Decades Is Spitting Solar Flares at Earth

SOLAR FLARES INFLATIONARY GEOMETRY – Negative Axisymmetric Curvature

TIME

The sun’s largest sunspot region in more than 20 years is facing Earth, sending solar flares our way and threatening a coronal mass ejection (CME), which can cause auroras and significant disruptions to our power grids.

Sunspots are relatively cooler regions of the sun visible on the surface, with complex magnetic field activity. The sunspot region AR12192 is the “largest sunspot group since November of 1990,” according to Doug Biesecker, a researcher at the National Weather Service Space Weather Prediction Center. AR12192 is roughly the size of the planet Jupiter, but the largest sunspot on record, seen in 1947, was three times that size.

AR2192 has been sending out high-energy solar flares but thus far no CME, which, Biesecker says, tend to be more closely associated with the magnetic complexity of a sunspot region than with a region’s size. A smaller solar storm around Halloween back in 2003, for example…
