That giant sunspot that supercharged auroras on Earth? It's back and may amp up the northern lights with June solar storms.

Two panel image on the left the sunspot is visible on the limb of the sun as a dark patch against a monochrome sun and on the right it is flaring with large fiery looking plasma loops of yellow. .

Earlier this month, solar active region AR 13664 produced 12 X-class solar flares across six days. 

The first batch of flares triggered successive Earth-directed coronal mass ejections (CMEs) — large expulsions of plasma and magnetic field from the sun — resulting in a G5 geomagnetic storm at Earth.
