Huge sunspot fires off intense solar flare (video)


(SPACE.com) A gigantic sunspot unleashed an intense solar flare early Thursday (July 19), though the solar storm shouldn't pose any serious problems to us here on Earth, scientists say.
The flare erupted from a sunspot known as AR 1520 at 1:13 a.m. EDT (0513 GMT) Thursday and peaked about 45 minutes later. The outburst qualifies as an M7.7-class solar flare, meaning it's a bit weaker than the sun's most powerful blast, X-class flares.
