Wednesday’s solar storm peaked around 4:25 a.m. ET, when the sun fired off a huge X-class flare, hurling streams of plasma and charged particles into the cosmos.

NASA's Solar Dynamics Observatory captured the moment of eruption, which has been classed as an M8.3 solar flare—and which almost reached an X-class on the scale.

The solar flare, categorized as X-class in scale—the highest scale, was triggered by an active region of a sunspot on June 19 at 11:50 p.m. UTC.
