Sun Unleashes ‘Spectacular’ & Powerful Eruption
The solar storm hit its peak at about 2:41 a.m. EDT (0641 GMT), but the actual flare extended over a three-hour period, said C. Alex Young, a solar astrophysicist at NASA’s Goddard Space Flight Center who runs a website called The Sun Today, in a video describing the event.
