"AR1654 is getting bigger as it turns toward Earth," the website reported. "Not only is the chance of flares increasing, but also the chance of an Earth-directed eruption. This could be the sunspot that breaks the recent lengthy spell of calm space weather around our planet."

According to Spaceweather.com, sunspot AR1654 is growing more active and is now "crackling with M-class solar flares" like the one that erupted today.

The surface of the sun erupted in a solar flare early Friday, unleashing a blast of super-heated plasma into space.
