The sun has erupted with its first X-class solar flare of 2015, a not-so-subtle reminder that it can still muster the energy required to generate the most powerful class of solar explosion.

The magnetic eruption occurred yesterday (Wednesday) at 12:22 p.m. ET (16:22 UT), lighting up a huge area in the lower solar corona (the sun's magnetically dominated 'atmosphere'). Shortly after the huge eruption, that measured X2 on the scale of flare energy, Spaceweather.com reports a radio blackout was detected over large swathes of the globe, including much of the Americas.

"The X-flare scrambled the ionosphere thoroughly so that no decametric radio signals were supported in my part of the world," said amateur radio astronomer Thomas Ashcraft.
