The flare had a magnitude of at least X9, making it the most powerful solar eruption of the current solar cycle — surpassing a monster X8.7 magnitude blast in May.

The huge solar flare, which registered as a powerful X2.2 sun storm, occurred began at 2:38 p.m. EST (1938 GMT) and reached its peak strength 48 minutes later.From start to finish, the intense ...

Colossal solar flare erupts from Earth-facing sunspot, sparking strong radio blackouts over Pacific Ocean (video) Related: We may have just witnessed some of the strongest auroras in 500 years.

The latest flare, which is the largest of the current solar cycle, is the sun's most intense outburst since 2017. And an even more powerful explosion could be on the way.

Earlier this week, NASA’s Solar Dynamics Observatory (SDO) recorded a rarely seen event—four nearly-simultaneous flare eruptions involving three separate sunspots, as well as the magnetic ...
