A very large sunspot: the AR2924

Sunspots seen by SDO / HMI. Sunspot AR2924 has quickly become one of the largest sunspots of the young solar cycle 25. Any flare today will be directed toward Earth.

AR2924 has two dark cores as wide as Earth that support a scattering of points the size of an asteroid that stretch out over 150,000 km of the sun’s surface. These dimensions make it an easy target for backyard solar telescopes.

Up to now, the sunspot has not produced major flares. However, if it explodes, the explosion will be directed towards Earth.
