Sun Spits Out Biggest Solar Flare

the sun unleashed its strongest eruption of the weekend yet, triggering a radio blackout even as the star continues to crackle with solar storms.  

According to NOAA's Space Weather Prediction Center (SWPC), the dynamic solar flare occurred late Saturday (May 10) from an active sunspot region called AR3664. 

As a result, parts of some of the Earth's sunlit side had temporary or complete loss of high frequency (HF) radio signals.  

It peaked at 9:23 p.m. EDT (0123 May 11 GMT), registering as a massive X5.8 class flare, SWPC officials said.

The sun, proving that it wasn't done yet, also fired off a powerful X1.5 solar flare at 7:44 a.m. EDT (1144 GMT), NASA officials said. 

X-class flares are the strongest types of solar eruptions from the sun, and while flares can last anywhere from a few minutes to hours, to get these high magnitudes aren't as common.  

the sun has fired off a series of powerful flares this week that have supercharged Earth's northern lights displays.
