A mixed sunspot emits a powerful solar flare

A jumbled region of sunspots pointing almost directly at Earth has just emitted a large solar flare, which could wreak havoc on power and communication networks for days to come.

NASA Solar Dynamic Observatory (SDO) first detected the sunspot area designated AR3006 (“AR” stands for “active region”) several days ago; now the region is located near the center of the sun’s visible disk.
